Most lists about how to save money on gas suck. They tell you to buy a different car, or remove all the weight from the back of your car. These solutions are either not realistic or painfully obvious. That's why I created this video, to offer driving techniques (which are free) that allow you to get better fuel economy in your own car, regardless of which car you drive. Often times, you don't even need to slow down, and some of these driving techniques are not only more efficient, but they'll get you to your destination faster as well.
We'll discuss how to approach stoplights and heavy traffic, how to handle hills, and whether it's better to accelerate lightly, or with moderate throttle while short-shifting. We'll also discuss how to properly incorporate engine braking into your driving, which uses no fuel at all, and can extend your brakes' longevity. Check out the video for all the details!

I’ll go on record and say 95%+ of people don’t understand the concept of coasting
Haha nope, flying up to stoplights like it's gonna get them somewhere faster.
Engineering Explained right?! Or on the freeway with brake lights ahead and immediately on their brakes. Just coast... who knows, maybe you’ll never have to touch your brakes.. Save $ on both brakes & gas...

I save money on gas by buying a new car everytime I run out of gas.
lol, saving on 'gas' but not 'money'
I really hope your local dealer fills the tank before the purchase ... :)
Bruh what? 😂💀
I didn't think I'd have to make it obvious that this is a shitty joke.
@Stephen Hill r/woosh
It really amazes me how big a hurry so many people are in to wait at a red light.
Gotta respond to that new notification on their phone!
The reason realy is, atleast here in Germany, that the traffic lights have weight sensors.
So if there is no car standing at the white line, the light will stay red for longer
They're trying to get in front of you whose driving under the speed limit.
I'm so glad to see I'm not alone. Also, when in heavy traffic, I refuse to start and stop 50 times. I'd rather coast at 15km/h in first gear.
I see that everyday I going to work. Even I pass them at every green, them race ahead - never learn!
"Use less brakes"
A car comes in front
Me : Heavy sweating
Increase following distances
Me when I had to nurse our car home when one of it's brake caliper didn't get pushed back by the spring inside and thus would cause the brake to constantly rub and get hot. Managed to travel 50 miles without actually using the brake
@@or2kr This man needs to race at Le Mans.
Release the gas, and press the clutch.
Ahhahaahah
I always consider it a win when I'm still rolling as the light turns green.
Instant dub then you end up getting past the next light to and the person who went light to light doesn’t make it
Even if you're barely moving, it's still a ton of momentum saved compared to starting from a dead stop.
Especially true when you're shifting!
@@rars0n jajaja about 2 to 3 tons on avarage xd (pun intended)
Just started driving with my learner’s permit and I already manage to do that
Well unfortunately I realized my “lead-foot syndrome” takes a quarter of a tank from my mom’s Toyota Sienna in just 2 days of back and forth from school ._.
Dang fun comes at a price indeed
I love it when people fly by me while I'm coasting, have to stop, and then they have to watch me fly by them because the light turned before I got to it.
They usually end up a whopping 1 car ahead most of the time. All that throttle to save them 3 seconds off their journey.
Thats an amazing feeling.
@Tony, very true. Always have to check the cross traffic before breaking the coast. Another hazard is that someone towards the back of the line will get the urge to cut me off so they can beat the first car at the light.
Jase, I coast to a red light also when possible so you dont always have to stop but more often then not some idiot(s) will race past and cut back in front of you then stop at the red light, then you have to stop too as they seem to have a slow reaction to the green , maybe checking their phone while stopped?
I drive like you too and I make a game as to when I'll see a car that flies past me at which light and how often.
@@roughas100 Yeah, that's what usually happens sadly.
I can’t stand the people who are constantly tapping their brakes on the highway to slow down slightly. It’s like they don’t understand the car will slow down if they just let off the gas.
There's a lot more they don't understand.
It cancels cruise control (although there is a button for it) and signals the driver behind one is slowing down. Because WAY to many drivers follow too closely.
As the other person mentions, too much tailgaiting going. That is why I usually tap the brakes even though I don't need to. I will not do it if nobody is behind me, but otherwise it is safer to show that I am slowing down.
coen071993 Hitting the brakes when someone is tailgating is very dangerous. Obviously the tailgater is in the wrong, but you could cause a chain reaction crash. I’ve seen it happen. Just take your foot off the gas and the car will slow down on its own due to friction and engine braking. You shouldn’t be touching the brakes at all on the highway unless it’s an emergency, or you are in bumper to bumper traffic.
@@Rocky32189 The issue with it is that both things are dangerous because not tapping the brake sometimes means they don't realise you are slowing down.
The best way to truly understand these principles is to cycle. You will really notice these points on efficiency, as your legs will be doing all the work.
Great advice
Period.
cycle what?
@@feelinghealingfrequences7179 A bike... 🚴
yup. agree
Instructions unclear. No longer stop at stoplights.
😂😂😂
That's the ultimate way to save fuel. After you didn't stop at stoplights you got into an accident an destroyed your car.
-> No driving -> no fuel used -> max fuel saved ;)
Melvin Klein 1 million iq
You're obeying higher laws.
You joke, but picking a longer route with fewer traffic lights may actually be more fuel efficient, depending on the extra time spent driving vs time wasted idling
Predicting traffic movements and reacting accordingly in time generally does a good rule of thumb to save fuel
Oh my God there is others I was losing hope. My whole family says i dont need to worry about other drivers and how they are moving
@@kenworthkid998 Your entite family are idiots. Not paying attention is how you get into accidents, 'cause there are enough idiots on the roads
I'd say that's the most important thing above everything else when driving. Not only saves your fuel AND fuel of others (if you keep slamming your brakes you'll confuse others too), but also prevents accidents and is less exhausting for all drivers as it makes traffic more fluent.
99% of people on the road don't do this and doing it can sometimes get you into an accident
Small caveat: if you're constantly changing lanes in traffic to go to the lane with the least amount of traffic and most amount of open space, then you might be saving fuel but causing massive phantom traffic jams.
It all depends on how you're reacting because most people just want to save themselves a small amount of fuel while destroying others' fuel economy.
10:00 “does that mean that you should be flooring it at every stop light?”
Mustang owners: absolutely
@Triston Stuart oof you get an 80s stang?
Why just Mustang owners? Flooring it on every green light is worth it even in an e-Up!
Just about every other driver I see: "Absolutely!"
The sad thing is that we (hardcore viewers of Engineering Explained) are already using these techniques (and are BTW pleased to hear that Jason confirms we are doing this right), but exactly those people who DON'T watch these type of videos are the ones who really need to understand the True Driving.

This reminded me soo much of YOLO by Lonely Island from when it first came out
That did not age well...
Any time you use your brakes you're throwing away energy, so the less you use the brakes the better your fuel economy.
Unless you have a hybrid or EV, then braking *gently* is generating energy. It's basically coasting with superpowers. 😋
@@mjc0961 The regenerative brakes on an EV aren't 100% efficient, so while they're much better for your economy than using the regular brakes they're still worse than not braking at all.
AND SAVE THE PLANET
@@mjc0961 That's only because the car is smart enough to not actually use brakes.
So if there's a kid running after a ball across the road, don't brake at all; you save energy and the planet from overpopulating.
Most satisfying thing is when one of those drivers that thinks he is cool overtakes you and eventually he just ends up standing still at a stop and you just cruise pass him.
When I drive my Super Beetle, I approach the hill at 45, floor it, and am doing 25 at the top of the hill.
💀😂
Same for my 87 tracker
Back when I owned a few air-cooled VW's, they would pull most highway uphills at about 55 mph, in third gear at full throttle. The only trouble was, the transmissions had too much gap in ratios between second and third. You could only go about 40 in second, but you didn't really get on the power band in third below about 50. So, if you got caught behind a truck or other slower vehicle, and had to slow down below 50, you would be stuck in second gear at 40 until you got to the top of the hill.

I have never seen in my limited 5 years of driving experience ever seen anyone else coast in traffic like i do. Helps alleviate traffic and saves money and makes you calmer and more focused driver.
Yes, after 35 years of driving, 10 years bicycle commuting, and now a couple of years on a motorcycle commuting, I'm really not in a rush to go anywhere. If people are getting all uptight I'm VERY happy to move over and let them get as far away from me as possible. If someone wants to drive like a nut, there you go buddy you just move on past and get in front of me. WAAAY in front. Enough that I have time to brake before I come to the wreck you caused.
Exactly. Especially merging. I'll go off on a whole rant there if I get started. Idk why people think 6 inches off anothers bumper is the fastest way to move.
@John. Agreed. I had to drive cross country a lot due to a job. Out of boredom, I'd play with the math to see what different speeds would save me time wise. Not worth it usually.
A trick I like is someone hanging in your "blind spot" ( i have too many mirrors to have one) when you want to lane change. Blinker makes them be nice and slow down or be an ass and punch it. Either way, they are now out of your blind.
@@paulparoma rushing, pride, and a false sense of invincibility. That's what I think are the main culprits to the frantic, unsafe, racing mindset many drivers have...
@@paulparoma agree. Advertising gone wrong, perhaps. Nobody can defy physics, even if we all want to...!
It's almost impossible to coast with a 45-50 mph speed limit at red lights. They change to red to fast which makes roundabouts actually safer.
i love how Jason supported everything with mathematics ang computation. no beliefs and speculations. maths dont lie.
It gets addictive over time
Yeah but he still makes mistakes.
The power used to fight fluid friction is indeed dependent on v², but the coefficient C_d (d for drag) is ALSO dependent on speed. Sometimes, you can increase your speed by just a little bit, and C_d gets divided by 2, which is nice.
Also the power produced by the engine is not exactly the same as fuel consumption, because the efficiency ratio is not the same for all RPM (as he stated in argument #5, so if your gear transmission is correctly designed (as well as the car's aerodynamics), you should drive at the speed limit.
His math is often bad. At 3:32 he explains that V^3 (velocity cubed) means the power increases "exponentially", but he doesn't understand what this means. V^3 is a polynomial function (simply cubed). Exponential would be something like F^V (F to the power of V, where F is some factor, and V is velocity again). That grows much faster with increases in V, which is why "exponentially" means growing very fast. But this is not exponential. He repeats this "exponential" mistake later too. Maths may not lie, but people can lie about maths (though I don't think this was intentional).
@@johnjones7400 yeah, I was like... That's not exponential, lol
I learned that first method with stop lights while driving motor scooters in town. If you slow down to give yourself more time before reaching the red light you have a better chance of reaching it still moving and you actually end up passing everyone that had rushed up to the light and then stopped.
I have been especially interested in vehicle efficiency for about a decade and I can stand behind all your explanations. Even though I knew most of these I'm glad to hear it explained so clearly and with great detail.
As I have learned, common sense isn't that common.
Strive to have uncommon sense.
True, but the meaning of common sense is incredibly subjective
There would not be a highschool course on basic physics if it were common sense. Get off your high horse.
It's pretty shocking people don't know this stuff.
Incredibly common sense but 80% of the people I see race towards red lights, I'm just off throttle and engine breaking they blow past me, some time under taking and then break last minute. It's litteray like they can only see 10 meters ahead. I seriously dont understand baffles me I'm not exaggerating
Friends and family make fun of my 'old man' driving because I use these techniques whenever I can but are surprised that I maintain my speed limit on-ramps instead of braking like everyone else. They're even more surprised when my driving gets spirited in curves. Little do they know that I'm keeping myself entertained by challenging myself to drive efficiently.
What is about highway ramps that cause people to brake even when it's completely unnecessary? I see this every single day, and it drives me nuts.
@@rars0n people just have no confidence driving,

A small point: the amount of power required to overcome air resistance in relation to the speed is not exponential, but cubic (still polynomial). But otherwise fantastic video :)
English is not my native language so I didnt learn maths stuff in english but here a kubic function is still considered as exponential growth or exponential correlation. Also in theory you could write x^3 as a power of e so thats still an exponential function. :P
@@invalid8774 x^3 is not exponential growth, 3^x would be exponential growth. You cannot express x^3 as a power of e, but you can express 3^x as a power of e. In order to be exponential growth, the rate of change needs to be proportional to the current size. The rate of change of x^3 is proportional to x^2, not x^3, so it is not exponential. The rate of change of 3^x is proportional to 3^x, so it is exponential.
@@invalid8774 LOL. By your logic, a constant function like f(x) = 8, should also be exponential, cuz 8 is 2^3.
I believe the hill solution could provide more insight by also computing a correlation coefficient of a linear regression between the dependent and independent variables. Obviously, based on constructive knowledge, speed, distance, and time are independent variables and fuel consumption would be the independent variable. The absolute value of the standardized coefficient for each independent value can compute the variance to the dependent value to answer which of the independent values affects the dependent value. Just a thought. Probably not practical for real world driving 😂 but if you mapping a rout and want to maximize your fuel consumption this would be a fun little project. 🤷🏻♂️.
I always do tip 1 and it makes me feel like some kind of wizard when I see everyone else racing to get to a stop light then I just casually cruise on by them in the other lane right as the light turns green. The thing is, it's common sense, it shouldn't make me feel like a wizard...be better drivers.

Spot on video.
"Drive fast when you need to stop" is literally the optimum way to approach a red light, where "fast" means "keeping the minimum speed as high as possible". This is only perfectly achieved if you know exactly when the light will turn green. You would immediately brake down to and maintain a constant speed that would carry you to the intersection in the time it takes for the light to turn green. In reality, there is some uncertainty as to when the light will turn, and traffic behind you might get annoyed if you apply your brakes "prematurely". So use your best judgment in traffic, and if feasible, use engine braking exclusively to slow down as you approach the light, so that you are at least decelerating at a steady but modest rate well before the intersection, buying yourself more time to coast while not using any fuel, and not annoying the cars behind you to do so.
"Drive slow when you need to go" is pretty accurate most of the time, except when the speed limit itself is set very low. If you can reasonably get away with driving over the speed limit when the speed limit is 5 mph, 10 mph, or 15 mph, you will get significantly better fuel economy in basically any vehicle (FE at 10 mph is approximately double the FE at 5 mph, and FE at 20 mph is typically somewhat close to double FE at 10 mph). Cars typically achieve their best fuel economy somewhere between 20-40 mph, with small-engined, low power/weight cars (ie Toyota Prius) peaking in the lower end of this range, and large-engined, high power/weight cars (ie Chevrolet Corvette) peaking in the upper end of the range. The drop in fuel economy due to increasing air drag is usually not significant until speeds reach 50+ mph, depending on the aerodynamics of the vehicle. For best highway fuel economy, drive in the far right lane as slow as you safely can. The denser traffic is, the smaller your speed differential relative to the flow of traffic needs to be. If traffic is very sparse, you might be able to drive at the posted minimum speed limit, but when doing so, you need to be constantly watching for cars approaching from behind in your lane and accelerate to a reasonable speed as they get close. Never drive slower than the posted minimum in clear and dry road conditions when traffic is freely flowing. You will notice the most dramatic improvements in fuel economy using this technique on the higher speed limit freeways.
"Slow up; fast down" for hills is optimal because it reduces your vehicle's average speed and allows the engine to do its work in a more efficient manner. You might also find that hills where the elevation change is substantial enough, increasing throttle on the uphill sections such that your speed drops gradually to 5-10 mph below the speed limit by the crest of the hill, places the engine at a more favorable BSFC. Then coast down the hill in neutral or in highest gear with very light throttle to allow as much of the stored potential energy to be converted to kinetic energy as possible.
"Shift early" is an optimal strategy because it keeps engine rpms down and engine load higher, which places the engine at a more favorable BSFC, as long as you're not lugging the engine. As far as accelerating softly; this is actually not as efficient as accelerating at higher engine load, depending on the distance between stops. In city driving and on residential streets, accelerating harder (half to three-quarters throttle) from a stop light/stop sign allows you to reach the speed limit earlier using less fuel and begin coasting sooner to the next stop. If you want to lower your average speed, just don't accelerate all the way to the speed limit (say 5 mph under). If the speed limit is 45 mph, then accelerate to 40 mph efficiently and quickly, hold at 40 until you're close enough to coast to the next stop, then coast in neutral the remaining distance. You can take this one step further and try pulse-and-glide, traffic permitting. You would accelerate to 45 quickly and efficiently, then immediately begin coasting in neutral, down to 35 or so, and then accelerate again quickly and efficiently back to 45, and repeat the process as necessary to cover the distance. This method of driving is a lot more fuel efficient than driving at a steady 40 mph, since the engine would be at a very low load driving at a steady 40 mph.
Of course, driving a manual transmission vehicle gives you more control when applying these techniques.
5:30 the most frustrating thing about where I live is that drivers will _speed up_ to red lights and rage at you if you slow down at lights you obviously cannot make. But I generally try and do this. I had no idea it was better for fuel economy.
Great video, man. stuff like this really helps.

I was filling my 2006 Focus every 10-14 days and now I'm filling my 2020 Kona every 21 days. I'm pretty sure that the difference is not just a more efficient engine, but better driving habits -- the latter owing to the Kona's fuel economy meter making me more conscious of how I'm driving.
For sure, i went from a 2002 V6 Gallant to a 2020 Corolla, the amount of fuel efficiency is 80% of the battle
"Patrick, where's the boat?"
"It was on "E" for "end", so I threw it out"
I’m always puzzled when there’s a stoplight and there’s a person eager to get to the stop quicker. I coast to a stop and it usually turns green before I have to push the brakes.
The best thing is when you can see the lights for the other directions or you see the walk signs and you figure out exactly when the light will turn green.
Im in the car driving sometimes and passengers will say go faster! And im like for what?? You wanna be at that red light quicker
Depends on my mood. when im all chillaxin' and maxxin' im like that, but when im worked up, i go with the "save my brakes" option. (short hard braking wears brakes out less quickly)
It really depends on the scenario. If you coast to a stop light and a bunch of cars behind you are trying to make it through a previous intersection, they now have slower traffic ahead because you are driving 20 mph under the limit. This multiplied by the number of drivers doing the same, is one of the causes of traffic.
I'm more than puzzled...I'm downright angry at their stupidity. I do wonder though, maybe they dropped something and need to safely look for it so they hurry to stop...that's usually not the case though. It's usually just stupidity.

good luck with that
I had to teach my boyfriend this recently, but he's quite logically minded and open to ideas so he was quite receptive to it.
After a bit of practice he found that not only was the ride smoother from not having to brake as much, but overall range increased by ~15%.
Unfortunately he still gets caught up in fear based ideas though.. like our Range Rover had DPF issues a number of months back so now on his way home from work if the DPF system starts a regen cycle he will purposely drive an extra 15-20km around the highway before coming home, wasting time and fuel just because he's scared it will immediately clog up on him if he doesn't.
For reference, the issues it had were quoted by our original dealership to be $3,000 in repairs.. while another dealer literally at the other end of the street just updated the software in 45 mins for free which fixed all the errors and improved economy by 1/3rd instantly.

@@kunstderfugue only if traffic is light enough for people to easily get around you, cause if you are the one causing a train of cars behind you, I would like to slap some sense into you
also your engine and transmission will wear less
@@kunstderfugue For long hills, you don't need to slow down because you can do that when you near the top of the hill. And since the aerodynamic drag doesn't change much, might as well stay at cruising speed for higher efficiency until you near the top of the hill since the load (weight of your car x distance x grade of hill) remains constant.
Pablo López-Ortega usually hills on highways are quite long so like others have said unless traffic is extremely light then no you’re going to cause problems.
I’m glad you posted this cause I’m at a quarter tank and don’t get paid till Friday lmao
You’ve got this!
Did you make it?! Checking in a year later
Abdulaziz 😂😂😂😂
I also want a resolution to this
Great explanation!, thanks 🙏
Hey here in the Netherlands we get taught this kind of stuff in driving school. And it's a requirement for when you get your driver's license.
I guess that should happen at more places in the world 😅
It is pretty common in Czech republic too. Although some private driving schools do not teach this behaviour from what I gather. How their students get a driving license is beyond me.
@@pavelkryl457 Ah yea, in the Netherlands I know tho, they test this on your theory exam and again during practical exam so there really is no way around it here atleast.
I enjoyed reading 0 mph as "Omph" as in the sound Driver 1 makes as he stops.
Lol, I read it that way aswell.
Jeremy Clarkson said something about frequent braking wasting fuel a while back. Some cyclist got in the way and he joked about running them off the road to save fuel or something like that lol
As usual an excellent video. Thank you!
Cool vid! I do all these things already and hardly ever see anyone else do them. The hill one especially, it's super funny watching people floor it up a hill to maintain their speed.
1. drive a manual.
2. keep the revs low.
3. quit mashing the throttle at every light.
I get better combined mpg than the internet says i should be getting on the freeway. Anyone else?
Absolutely
Basically.
drives an STI
i want to hear the turbo whistle loool
Almost correct. You should drive an automatic of the proper type. With a modern ECT or DCT you don't have the losses of a torque convertor and the computer is much better at keeping the engine in the optimal rev range than you are. Depending on the application a CVT or serial hybrid system can actually be the most efficient solution.
My favorite technique is driving my car at the highest gear at the lowest RPM (when possible) and timing stoplights to minimize my loss of momentum.
Highest gear and lowest RPM possible isn't always the best. Too low rpm and too much load can create a worse efficiency. Also your engine, dual-mass flywheel and drivetrain don't really like too low rpms.
Right, it's called lugging the engine. Basically if you can floor it without picking up speed, you're lugging, which is bad for the engine in the long run and there's no real benefit to fuel economy anyways.
It’s really all down to your car I couldn’t physically lug my v8 if I wanted to without stalling
Hey Jason, I love the video, a lot of these techniques I learned early on as a driver from a few sources. One was my Driver's Ed instructor, one was from The Kim Commando show about how to be a "Mileage-mizer", and one was from when I attended CDL school and drove for Prime Inc. which limits their trucks to 62mph and 65mph to save fuel economy. I would like to see a video about Engine Brakes like the Jacob's Brake.
Well explained. Thanks bro
it is actually a common sense that every expirience driver does on daily basis.. but this guy know how to explain it educationally.
Every experienced driver? What a joke, as someone who puts on 120,000+ miles a year I can assure you that no possible bracket you put drivers in would have everyone doing anything the same, hell it would be a miracle if half did the same thing. Except being on there phone while they drive, that's like 75% of everyone on the road.
I was driving like this on my driving lessons few years back and the instructor was amazed and said no one learning drives like this and I was just like it's complete common sense... Doesn't everyone drive like this?
I've actually been doing most of these since I started driving. I'm geeky. I like efficiency. I went and learned all this and literally made a lifestyle out of it.
But as he said, at the same time I had to learn to be courteous and aware of what other people are doing around me. I highly recommend everyone do the same. You can only maximize a lot of these techniques on relatively empty roads.
Coasting alone I find saves you the most. you can still coast and not bug ppl too much, just don't brake last minute.
Old video but a great one. I've recently upgraded my car and now have dynamic cruise control that keeps me a set distance behind the car in front, I think I've got mine to 2 seconds gap. I'm amazed how close everyone else drives, causing them to stop start. Sooner self driving cars come in the better.
Great video and advices
Unfortunately, a lot of these strategies will piss off the drivers behind you.
11:41 Which is why he states to be conscientious of other drivers around you and not to annoy them
@Mark Skowron Totally fair point. Hopefully, your state doesn't have a traffic law where you can be ticketed for impeding the flow of traffic, like California does.
that's their problem
@@EdwoodCA, I bet the law is in the books in order to conserve nature and help people save on gas.
@Mark Skowron You can't really be in the right on this subject. Question is, what priorities do we as individuals have? Your priority might be to save gas and be gentle on your engine, while someone else prioritizes dynamic driving and experience that comes with it (not speeding, just dynamic), and don't really care about fuel economy. It's a matter of perspective, you can't say someone's wrong only because they have different point of view.
I’m glad you added that very last part, I already do all of these things regularly but not in heavy traffic. I’ve been stuck behind people doing them in heavy traffic and it’s annoying as hell. Especially if someone is coasting up to a red light in the left lane which then makes me miss the green turn arrow making me wait an extra 20-30 seconds at the light.
In that scenario, they saved gas by making you waste your gas.
great video man very informative!
Triple like this one. I always wanted to find an efficient way to communicate exactly this to people. Now, I can just reference it. I call it a "red light race" as drivers are competing, who will be at the red light first and sitting there with engine idling. Similar to the hill racing. This, btw, shows that using cruise control is not the most efficient way of driving. Thank you very much for this video! Love it!
The stoplight strategy would work well if people could estimate light timing. Instead they start coasting way too soon, take too long to speed back up and then the light is red again before we get there and everyone has to stop. This also doesn't take into account that often a brisk acceleration will get me through the next light before it changes and a slower acceleration, while saving fuel, leaves me idling at the next light and triggers a pattern that ends with me waiting at nearly every subsequent light. Your city's traffic planning may vary.
First my apologies for using metric measurements (because I’m translating my text from another site to here) but here goes:
Here in The Netherlands we may travel 130 km/h on the highway but because we have a nitrous oxide crisis next year we will lower it to 100 km/h during the day.
Now some motorists were furious because they said “this will waste hours of our lives!”
I started calculating in my, quite common, commute to check that statement:
On my daily commute I have driven 130 and 100 km/h and measured the time gain of 130 to be at one minute per day.
My daily uses 5,2 liter per 100 kilometer at 100km/h and 8,3 liter per 100 kilometer at 130km/h.
I travel 40.000 km per year. 80% of those are highway kilometers. That’s 32.000 kilometer. At 100 km/h that’s 1664 liter and st 130km/h that’s 2656 liter. That’s a difference of 992 liter per year. For my car that equates to 24 extra gas fill-ups. An average fill-up will take me 10 minutes (braking, stoppen, waiting for a free pump, driving up to the pump, getting out, using my bank card, tank, noting down kilometers, leave). So driving 130 would cost me extra:
€1587,- and 4 hours (tanking).
I work 5 days a week with 24 holiday days so around 236 days. At130km/h I would save almost 4 hours (3,92) of driving.
So 100km/h will cost me zero hours extra a year compared to 130. What’s more: driving 100km/h is less stressful, generates less noise, makes it easier to coast / keep a safe distance / drive at a constant speed.
My daily car is small, light and has a small engine. Driving 130 gives you extra adrenaline because of the screaming engine so you start to drive more aggressive.
By the way: in real life traffic one rarely can drive 130 constantly so you have to brake and accelerate more, which uses even more gas.
In conclusion: driving fast and aggressive in daily traffic doesn’t save real time (due to more fill-ups), gives more stress and costs a lot more.
I sound like an old dude now but it’s just common sense 🤪
Quite a large difference in fuel economy at 130 km/h compared to 100 km/h: ~60% more, while you only expect ~40% more based on the aerodynamic drag, does this reflect errors in measurement, more slowing down and accelerating or a lower efficiency at higher rpm?
Also: please don't apologize for using metric measurements.
wvdh well a few weeks ago the engine explained itself all over the embankment. Although the engine bay said that the distribution belt was swapped not too long ago it broke and this tiny but powerful engine was an interference engine…
So the engine probably got a little sloppy at high revs too. A week before self destruction I noticed my normal mpg (actually lp100km) creeping up to 6 in stead of 5.2. I thought it was a winter thing (I rode on summer tires that were barely road legal - I wanted to buy new tires the weekend the engine blew up).
So I guess the internals were floating a bit all this time because ever since I had the car it would sound like a chain saw when cold starting.
@@wvdh drag goes up with the CUBE of velocity, kinetic energy with the SQUARE.
1.3x1.3x1.3=2.197 - so 60% vastly _underestimates_ the potential extra costs and as you go faster, air drag comes to dominate everything.
One of the reasons speed limits get set at 50-60mph (80-100km/h) is because this is about the highest speed at which aerodynamic drag is the least important part of fuel efficiency calculations. Below 40mph(70km/h) it simply doesnt matter at all for practical purposes.
Having to design for high speed slipperiness has a tendency to majorly impact a vehicle's _low speed_ fuel economy, usually by adding substantial mass. This is important because 90% of vehicles spend 90% of their time in low speed conditions.
No need to be sorry for using the correct unit of measurement
Thank u bro for this good video
Great tips!
In addition to those, when climbing a long hill you should speed up. Longer your engine works against gravity, more fuel burns. Don’t forget that gravity causes acceleration in the opposite direction when going uphill.
That actually isn't the case, for two reasons. 1) It takes the same amount of energy to go over a hill no matter how long it takes you to climb the hill. Potential energy= mass x height x acceleration due to gravity.
However, 2) the faster you go, the more air resistance there is, meaning it will take more energy to climb the hill. In conclusion, driving uphill faster will take more gas than driving up the same hill at a slower speed.
On another note, if the terrain is very hilly (up and down), it is beneficial to speed up slightly and not brake down a hill, because you will have more speed (kinetic energy) when you begin to climb the hill on the other side, meaning you will need to use less gas to climb the hill.
i drive at 40km/hr with my rpm at 1000, automatic transmission rav 4. would that harm the car?
@Cloudchaser, you should go at least 4k rpms for more than 30 seconds once in a while. Not that you should do that every journey but once in a month would be enough.
@@martinwilliamson5250 i dont think so. I know your science checks out as far as the physics goes but you have to take into account the engine efficiency. Steadily speeding up a bit BEFORE a hill (which i think is what hes saying) helps you stay in low rpm high load when going the uphill part without significantly increasing air resistance relative to the overall engine power
I live in the uk, and we save money on gas by buying petrol
Gas is petrol. Did you mean E85? (Ethanol) if you did mean E85, you will actually use significantly more fuel then if you used petrol.
@@TheUchihasparky It's a joke relating to how Americans call unleaded fuel 'gas', while in the UK, Australia and some others we call it 'petrol'.
Here in Aus, gas refers to LPG which is a totally different animal.
Ethanol is an interesting one, because when tuned correctly you can get significantly more power out of an engine, but you're certainly right that you use more of it.
In general, 100% ethanol means ~30% worse economy. As such, E10 (10% ethanol) is 3% worse economy.
The reason why some encourage it though is that the emissions and production are better for the environment when compared to regular unleaded.. but depending on the area and production facility that is still being debated too.
@@MotoCat91 yes, we essentially grow ethanol. And yes you get more power and its higher octane then 93 octane, but like I said, you use more of it
MotoCat leave it bruhh.. this fella is all gassed up. He’s not gonna get it
@@MotoCat91 Yup, the fertiliser production and soil destruction of corn agriculture means ethanol often hits a higher total carbon footprint than just using petrol. Leave it for racecars and liquor stores imo
Coming from sim racing I've been using these techniques and manage time to take less pit stop.
Works well.
IRacing?
@@santiagodamelio1013 i mainly play project cars 2, and dirt rally 2.0 This technique works in GT Sport too.
@@santiagodamelio1013 Some of this works in iRacing, but not everything. Mainly due to its far-from-perfect fuel consumption calculation ... iRacing only checks gas pedal position, it doesn't care about rpm. So coasting works, but using higher gear doesn't.
@@kenkalajdzic ah that's interesting, I never played Iracing because of the monthly fee. I already have a mmorpg for that..
Ok great advices Thank you
Fantastic video!
I been driving like this since I started driving Lol....I just thought it was common sense if you see a light that’s red ahead you start to slow down slowly
Heavy truck active cruise control with radar incorporates the decelerate up a grade technique, much to the chagrin of those travelling at a constant speed behind you. The trucking schools also train progressive shifting to save on fuel by staying in low RPM's too. It's important when you are moving a 30k lb vehicle (empty) and have around 10 or more gears to get through.
Very true - truck drivers are experts in economical driving, so following a truck (at a safe distance) is still a good idea for fuel economy, even if you're not drafting.
0:51 look at that the cyber truck
Very informative!
I’ve been coasting up to red lights for years. People behind me always get so agitated and drive around me just to get to the red light first.
Then you fly past them when you get there as it turns green.
@@JamesSmith-dn8lb I sometimes get to do that riding my bike in the bike lane.
J Walker Doing this in an ev is hilarious.

Thank you for the caveat at the end “don’t annoy other drives.”
That should have been articulated more. That hill thing can piss people off if there's any traffic.
From my experience, it can't be avoided.
@@josugambee3701 -- It can be avoided by not playing hyper-miling games when there are other drivers on the road who will find one's self-centeredness exasperating.
@@grizzlygrizzle I try to drive normally - drivers around here are just assholes.
@@grizzlygrizzle i just hang out behind 18 wheelers ;p
Excellent driving tips. I have also come to the conclusion that keeping tires inflated at maximum cold tire pressure will give you the best fuel economy. I have done an experiment between the lower recommended pressures given by tire shops and the maximum cold pressure with the result being that max cold wins in this fuel economy test.
I’ll try all of these tricks on my next trip and see how it effects my economy, great video!
This is why everyone should learn to drive on a manual it teaches you discipline
I dont know how to drive a manual because no one in my family drives one lol
@@paulparoma i dont know man ive feel more in synch with my car and what's going with it in general because of the transmission ive heard quite a few people say the same in one way or another over the years. Thats the best way to put it for me. I know quite a few of manual trans drivers out there and they're all good drivers except one. My pops lol hes got too much goin on most times.
I agree. Quite a few of these scenarios change significantly when you drive a manual. Gears don't change automatically for you so going down a hill at 45 might not actually take using your brakes. 75 in in 5th isn't the same as 75 in 4th as 80 in 6th. There's a lot more factors than mentioned here.
I drive Manuel daily
I have a Hyundai, a car with the fancy-shmancy "shiftronic" transmission.
It's just an automatic transmission with a +/- lever selection next to "Drive". It allows the driver to shift at will, by telling the computer what they want it to do (computer calculates if shift can be performed, based on several factors, and then does it).
The computer DOES prevent stalls, forcing downshifts as the car begins stopping. Other than that, it's as close to a manual experience as any automatic transmission vehicle can get.
Whoops. I rambled. On to my main point...
That car's unique functionality allowed me to begin appreciating just how combustion vehicles are able to do what they do. It also taught me RATHER QUICKLY what is good and bad for transmission operation.
The second I see a yellow light -> downshift
haha down shift to second.
Yeah I usually downshift and floor it.
Yea you can either slow down or speed up faster
Explained well 👍
Slower speed doesn't always correlate to better fuel economy and neither does more load at low rpm. As cylinder pressure (load) increases, the air/fuel ratio gets richer to make more power and prevent knock. This is especially true with TGDI engines where low speed pre-ignition is a major concern. An air/fuel gauge can be very valuable in this case as you can keep the rpm down and throttle open to just before the ECU increases the short term fuel trims. For the speed, same deal. Too low of rpm at too low of speed can lug the engine which you don't want. I was shocked to find that my wife's Altima actually got better fuel economy at 55 mph than it did at 45 mph. That engine is just at a more efficient rpm and load at 55 mph, enough so to overcome the increase wind resistance. Another note to that also, wind resistance only starts to become a big factor above about 55 mph. Below that speed, the air can usually drift over and around the car pretty easily. Above that, it doesn't have time to move out of the way and air pressure begins to build in front of the car. This also increases the drag (vacuum) generated behind the car. That air dam in front is something we take full advantage of in racing.
Good video, good points covered. I was ready to say that in scenario #4, most likely the person behind you would be on your tail, flashing lights, and giving you the “you’re #1” sign. But you redeemed yourself with your final point to be aware of traffic around you. Well dome👍.
TL;DW: To save fuel, go slowly and stay off the brakes. Imagine you have crates of tofu in the trunk... Oh wait

I take great pride in timing out coasting to a red light and hitting it just as it turns green so I don't actually have to stop it's quite satisfying

It's hard to do this in NY cuz everyone goes fast and lots of stop and go
Everyone drives like lunatics during rush hour. Literally all good driving habits get thrown out the window. I live in the city and the traffic is god awful, but it gets bad in some parts of LI as well.
@@kevinnorris6558 yep you literally see the difference during rush hour it's crazy
Thank you so much, I was seriously wondering about engine efficiency graph. Can you please do more of that in the future?
To continue on my comment: in Borger, Texas the main street had timed traffic lights with signs stating that if you maintained your speed at 35 m.p.h. you would hit every green light, and it was true every time I drove thru town and went 35 m.p.h. I would just go straight thru town non-stop. Pretty cool, wish more places were like that. Thank you.
I love that you mentioned the total drive time vs speed. Coworkers speed home from work every day (about 25 minute commute), I just do the speed limit. They might save 30 seconds on their total drive, which is all thrown out the window when they get stopped at a stop light and I happen to come by right when it's green. Of course, that can be random for any given day.
but it could also happen that they just passed the traffic light and it turned red just as you arrived
I used to really speed everywhere ... until I realized how little actual time (if any) I was saving.
"Power increases exponentially with speed" No, man! You just wrote that it increases polynomially! Exponentially would be P ~ exp(v)
Nice
Most descriptiona of exponential increase actually refer to polynomial indices, unfortunately. This is obviously a misnomer but it exists nonetheless.
It became a huge misnomer, because everybody wants to sound smart, so they use exponentially for pretty much anything that can be defined as “more aggressive than linear”. They don’t even bother
hah! I was thinking the same! But I always feel that I'll come off as a dickhead every time I want to correct people on that. So mostly I don't, but sometimes I do. It's amazing how many people, even with a fairly sound base in mathematics do this mistake!
@@mattegeniet very true, but I did not expect it from Jason!
Really like the closing statements. I had that at the back on my mind all through your video. Be mindful.
You're also putting more wear and tear on your engine when you're stopping and starting as opposed to coasting to the light. This also applies on takeoffs.
