- 10 Things You Didn't Know About The BMW i8. The BMW i8 brings a lot of firsts not only to BMW, but to the automotive world. From chemically hardened glass to it's highest specific output engine ever, from a unique leather treatment to exceptional aerodynamics, the BMW i8 is as cleverly engineered as it is unique in appearance.

Kerbal Space Program music!!
+Ali Mosa Haha, had to look up what this was! :)
Well the I8 looks like a kerbal space program invention
+Ali Mosa yep recognized it immediately
+Engineering Explained You actually might love this game, its about rocket science and involves physics :P
i knew it was familiar!
the engine looks like a sad pirate
Isn't the inline 3 the same engine that's in the Mini Cooper ?
+Mike Arredondo indeed it is. Mini and BMW share a lot of parts tho.
+Eduardo Boquin well they r made by the same company since BMW purchased mini
+Mike Arredondo Yeah, makes sense from a financial point of view.
I was just saying that it looks like a one eyes smiley face
More of these. The combination with such a music was excellent to hear, at least from my view.
+VisioRacer Glad you enjoyed it!
+Engineering Explained how much does the car cost so far
+Engineering Explained How do you get 356 bhp out of 3 cylinders, can you explain please?
+Robert Perry turbo, and electric motor
+Robert Perry Higher turbo boost pressure. However the ICE itself has got 'just' 231 PS (metric hp), while the electric motor has 131 PS (362 PS together).
3:19 but why? One of the main reasons why i would buy an electric car or a hybrid is the ability to sneak up on people or to be able to sneak out.
safety
ali han True
+TheAventadorSV I'd like to change that noise into a recording of myself going "VroomvroomVROOM!"
+ali han Ever hear of look both ways before crossing?
If you don't darwins law wants you dead, lets not prevent it
+IIGrayfoxII That feature is mostly for blind people
2:10 it looks so sad!
+Dean Bay yeah, look at all the dust that settled. how can one treat a beautiful car like that :(
Because it's a pile of crap haha
ksp sound ?
yep
Everyone knows that.
that is what I was thinking as well
2: This is illegal in australia
I would disable 10
Pedestrians should look before crossing the road, not Oh I don't hear a car I will go now
+edals90 not due to the number of lights working, but the lights must illuminate at a constant rate.
I would say this means no flashing during emergency(blinkers flash instead) or go dim and bright
To me this law is a bit stupid, flashing brake lights make more sense when doing an emergency stop than flashing blinkers which flash by design
+edals90 Yes you must have working brake lights, but the brake lights themselves must burn at a set rate.
No flashing/strobeing , no starting off dim and getting brighter
+IIGrayfoxII You must have forgotten about blind people. They rely on sound to distinguish where a car is. If the car doesnt have sound, they have no idea the car is there. This has been becoming a common thing in electric vehicles given those situations.
+derekjm1 Even people that can see rely heavily on sound to keep track of their surroundings, given the option they should never step onto a main road without looking but in shared areas you can't expect them to be constantly looking behind them to see if some ninja car is creeping on them.
+IIGrayfoxII The feature is probably disabled on i8s sold in Australia.
Boadcasted driving noise??? That means... It can be hacked and replaced with human representation of driving noise?!
"Oh look! Here goes an i8 -Brrrrrbubububub prrrrrr meeep meeep
The music made me double check if i had KSP running
That was interesting, BMW knows how to make a car.
Does the pedestrian warning scream "I have more money than you!"?
This takes me back to the vehicle assembly building
Good info, and nice music. No really the music was fine. :)
Great Car
Pedestrian safety? Why would a BMW owner want that?
Because they are all ignorant, like you.
Right? I never see bmw owners use signal lights at all
Was confused for a second because of the KSP build music theme :D nice music choice
Next video: 5 Things I HATE about the BMW i8
+Joe C No hate, just love!
Haha vehicle virgins reference?
Wrong channel..
+Joe C That was original.
+Engineering Explained to be honest, getting really tired of the 5 things I hate/love about whatever, don't be like those other guys, you're unique and have a good concept for your channel.
The background is the same as kerbal space program lol.
Is anyone else unable to think of anything but kerbal space program?
Can you make a video explaining how spoons work? How do they scoop so hard?
:)
How many space does the i8 use to open door. I am talking about is i8 will open the door easily when parking in the crowded parking lot?
ksp music nice :₩
I can't take his voice seriously with the KSP music
Kerbal Space Program background noise? WTF.
My greatest achievement was buying this baby
Do you know if the 3 Cyl the same one as in the Mini?
omg the music i cant concentrate KSP lol
What does the pedestrian avoidance speaker sound like?...
I saw my first i8 on the road besides seeing on a showroom floor. It's possibly one of most beautiful pieces of engineering on the roads today.
The likes of Tesla, BMW and Nissan will more than likely entice other manufacturers to introduce their own line of more appealing hybrids, with more of a reliance on the electric motors, or electric-only vehicles.
My only gripe is the cost. At this moment majority of hybrids and full electric cars start around €25k. In the near future it would be nice to see affordable, practical motors in and around the €10,000 price tag that's not a second hand Prius.
Leaps behind tesla, just not with the price which is funny...
What sound does the pedestrian protection system produce? Does it mimic a gas powered engine sound? Really curious about that.
Superbly nice vid by the way! and soundtrack too.
Rotary Rotor Literally it is spacelike sound of alienship floating :D
Lol, the music instantly felt familiar
Would the CD be better with the grill completely empty instead of that black cover?
+Sebastian Rosenberg Naa, if a bumper has holes that ar not "flow thru" it adds drag. Even the flow thru ones add drag but are usually there to convert drag into downforce.
"i" stands for injection?
Is this guy serious?
#9 at 2:55
"Having the electric motor upfront means that under deceleration, as load transfers to the front axle, more energy can be recovered versus a rear wheel drive system."
Did he come up with this theory on his own? Or did some marketing genius from BMW tell him this?
The only difference here would be the packaging of the motors in combination with the engine in the back with the smaller electric motor. Regenerative braking capability would be identical from one axle to the other. Plus they get the say that the car is all-wheel-drive, which sounds better than only being two-wheel-drive.
#9 should have simply been stating the fact that with the electric motor at the front axle and the internal combustion engine at the rear axle, it allows the car to be rear-wheel-drive, front-wheel-drive, or all-wheel-drive.
Probably depends on how aggressive the regenerative braking is. Load transfer means that more braking can always be done with the front wheels than the rear, so if the regenerative braking force applied up front exceeds the braking capabilities of the rear wheels, then what he said is true.
That theory would hold true if braking forces were allowed to go high enough to lose traction of the rear wheels. A Chevy Volt or Cadillac ELR with their 16.5kWh capacity battery can accept regenerative braking up to a maximum of 60kWh. A larger battery can handle a larger surge of energy coming into it, but even a Tesla Model S which weighs 4,936lbs (P90D & sunroof, etc.) and a 90kWh battery...STILL only has a programmed 60kWh of regenerative energy recovery rate. They have been this way regardless of being AWD or RWD, 60kW/70kW/85kW/90kW battery sizes. The BMW i8 lithium battery is only 7.1kW in total capacity. Highly doubtful that it would hit above 60kW of energy surging into it at such a high C-Rate.
It has to do with the driving experience of how a driver expects a similar behavior to what they may be familiar with from driving cars, such as manual transmission sports cars, in the past. Regenerative braking exists to provide higher efficiency on a commute, and 60kW is a sweet spot that mimics the feel of a manual gearbox selected in a gear that is one or two gears lower than you would cruise at, which is probably equal to no more than 20% of stopping potential at the very most.
Keep in mind that BMW's marketing department is who most likely mis-spoke when they mentioned this detail to him. Perhaps something was lost in translation.
Could you please do a video explaining drag coefficient? And what those numbers actually mean?
+Talis Broks You got it! th-cam.com/video/eWTsXrPWl5Q/w-d-xo.html
+Engineering Explained awesome! Thank you. Your video's are great! Super helpful.
Nice !
AH Kerbal Space Program Main Menu Music is the same song, was a bit confused there
It not the first 3 cylinders produced engine of BMW if you'd consider BMW motorcycles where BMW used to built the K75 with a horizontal 3 cylinders (the only motorcycle that I know with such a horizontal engine, crazy!). Although it's the first turbocharged 3 cylinders produced engine of BMW :)
Speaker for outer noise - great solution, i saw that problem with non-electrical cars very often, new (just bought) Hyundai Solaris at low speed have very low and non-structural noise, so you need to get very close to people to let them hear you, or use horn. Same problem was with Mitsubishi LancerX 2.0 L but it is hearable from 2-3 meters, instead of touching someones leg from behind (and he "oh, what's this?" than "POKE what are you doing here, sorry, go on please").
Cool video,thanks. It's always refreshing to get more gee wiz info on a car, especially one I'll never drive. Drag coefficient of 0.26? Not impressed. Same as a Mazda 6. They could've saved themselves tons of money (and the consuner) by spending less on aerodynamics that don't justify part of the price. The other stuff on the video is just neat. Thanks.
FWIW my 2015 Toyota Prius Plug-in makes a baby Godzilla roaring noise when at low speeds in EV mode to notify pedestrians. I believe the Nissan Leaf makes a sound at low speeds as well. However the other features seem unique to BMW and are pretty cool!
Hey! So I'm going to be majoring in engineering starting in September. I'm currently a grade 12 student. Can you provide any tips for first year engineering students, and some things you'd wish you would've known? Or how to prepare? Thanks!
How much cost for maintenance
Do the American's even need a noise to recogniz' a car coming?!
In Europa it's just an option, but no one orders it.
Why can a fwd car regain more break energy?
Yes the car dives in while breaking... But isn't this becouse of the breakbalance between the axles? So if the balance was 40:60 not 60:40 the back axles would regain' more energy right?
Of course I'm aware that the steering would be that good especially under ABS.
i'm honestly not a fan of the way the doors open... i don't like the scissor doors at all and the gull wing doors even less - they could have done it just as well with the cool new doors they have just opening in the normal fashion.
Very low vibration from an inline 3? Unless it is using a balance shaft you're off the mark. The apparent smoothness would be from the soft engine mounts and sound insulation.
My EcoBoost 1L 3 cylinder (same basic architecture) is far from smooth at idle. The engine movement at idle is almost comical.
hahaha, thought my KSP was open...apparently so did a lot of other people!! i love the vehicle though :D
I was working at a bmw dealership and we had a white i8 in the shop. while walking though the shop everything sensed fine no imminent danger, but about 3 quarters though the massive shop I look back and INCHES behind me was the i8 driving. it made zero noise. i mean zero noise. this sumabitch followed me across the shop starting at the end of the shop inches behind me in this car and I had no clue. I literally screamed when I saw that car behind me. I've driven the i3 many times and at some 3 miles an hour it mostly silent except some tiny transmission noise you hear if it's only a few feet away, but this i8 made no noise at all at that speed, i imagine at some 10mph or so it would make transmission noise. sitting inside the car is incredible though, absolutely love the interior feel
"very low engine vibration" lol what. The torque forces kill it. The engine mounts and balance shafts are taking care of those forces. Have you ever driven a 3 cyl without balance shafts and relatively stiff engine mounts?
I had to drive one of these for my old job. I didn't think to figure out how to open the door from the inside before I got in. It was pretty embarrassing.
OMG, this car is perfect for somebody that has actually managed to convince themselves that they need a smart watch. How's the weather out there...I better check my watch before I look outside!
NIce reference to KSP! Because in ksp you need to build space vessels as fuel efficient as possible too, using different engines as they did in bmw or multistaging or both)))
This car sell 333 thousand dollars in China.. Meanwhile in the US the price tag is only 135 thousand dollars... And I want this...
Kerbal Space Program background audio ... I played the game so long i grew hating that annoying sound when building my space ships.
These facts are trivial. Everyone knows about these. Pah why even my dog knew. You're slacking EE
I think they stole the car sounds idea from Traxxas RC trucks. They are electric but make revving noises when you accelerate.
The adaptive brake system lighting isn't anything new, BMW has had that in cars since the E38 7 series, my E46 has it.
How far have BMW gone with weight saving?
If someone wanted to save even more weight what could they get rid of or modify to make the car lighter?
Most i8 info vids overlap. This had 10 new features I didn’t know about. 👍🏽
Why does the electric motor need a transmission? Isn't the whole advantage of the electric motor that you have instant torque at 0 rpm with a relatively smooth torque curve?
Yep, it looks the i8 like a spacecraft, but not at the level to put KSP music :D
All new BMWs well for like the past 2 years have the pressure based extra brake light. Saved my ass 2 times.
It is interesting that w124 AMG Hammer had 0.25 Cd in 80-s.
Could you maybe make a video explaining why some people put their car in 2nd gear while being parked?
Why do everybody hate I8. I don't understand it looks so sexy. If it has bad qualities still buyin it.
You should've thrown a rock at the rear window to test its hardness
+Peter Jada It's inside the car haha, protected by rocks (by the front windshield and rear window).
+Engineering Explained I mean....you still could've thrown a rock at that window and one of the exterior windows to test their claims of increased strength 😁
+Peter Jada He could have, but if he damaged it which is most likely, he would be paying for it and BMW normal glass is expensive(german brand tax), let alone this "special" glass
Throw a rock at any car windshield and the windshield will crack
+IIGrayfoxII it was a joke...I think we can take BMWs word for it on the chemical hardened glass
150k and that's the engine bay?? yeah I'd rather not. they could have at least tried just a little bit to make the engine bay pleasing to the eye
Hey jason i think u should turn the gain down a little on you mic its redlining and starting to distort
something I just realized, this car us available in almost video games wonder why that is.
Looks like soud pollution from transport not going anywhere and btw i think pedestrians should pay more attention to their surrounding
All that styling yet a higher coefficient of drag than the kia optima plug-in's .24
What about the feature that tells u how long till the red light turns green ?
+Mike Arredondo That only works in some citys, I think. So no point reviewing a feature thats only available to only 0,1% of the people that is considering buying them.
+Mortalomena by some city's do u mean large metro areas where 99.9% of these car will be purchased and be drive in ?
People will still dislike the i8 because they have awful taste in cars, they'll prefer a Prius...
Environmentally friendly leather!? There's something I've not heard before lol
I think this is an amazing technologial achievment. Regardless of how it performs in sport situations, I think this definately paves the way for thoes futuristic cars potrayed in movies like "demolition man". I cant wait to see this merged with google's self driving cars
I'm slowly beginning to fall in love with this
it would be nice to hear the noise it makes for pedestrians while in electric mode.
BeamNG? Anyone? The SBR4 also has the brake light feature lol
How did you get your hands on an i8 for a youtube review?!
environmentally friendly method to treat leather? What, like not killing the cow????????
Your Number 10 is actually optional and will cost you a few bugs extra
I'll never get over the fact that the rear end looks like it's giving birth to a 911. *can't be unseen*
My 13 year old z4 has brake force based ligthing..not new lol
My friend has a black one in shanghai, I tried it once, very hard to get in and out of the car....
Doesn't it have a heads up display too like on the windshield I always thought that was pretty cool
Props on the Kerbal music :D
Most internal combustion cars make almost no sound at low speed. All you hear is tire noise.
Excellent presentation. Now, perhaps a video on heel-and-toeing?
Nice vids these days man ! +engineering explained
+J. Holder Thanks!
While I don't really like this car, it is quite impressive in a lot of aspects.
The KSP music is making me think there's multiple videos running
fun fact: there are 2 hidden ventilation in the bumper creating an airflow around the car.
why are you using kerbal space program soundtrack? xD
i thought i had kerbal space prograsm running when this video started.
I wonder if you can disable the engine noise coming from the speakers.
...is that really Minecraft music in the background?
3 cylinder has no better balance than 4 cylinder. It has perfect primary and secondary balance, but it has big rocking motion, it would vibrate more.
3 cylinder has better exhaust pulsing and it could be more efficient for turbocharging. And this is not first 3 cylinder BMW, because 2 series MPV uses same engine.
Fun fact - this engine is exact half of engine from BMW M3.
+Mladen Milić While it is half the cylinder count, it is not "half" of the m3 engine. BMW is not using the modular "B" platform engine in the m3, the m3 uses the s55 while the i8 uses the b38
+Mladen Milić it would have been first 3 cyl bmw when it launched.
There's already a bulletin out for the rear motor mounts breaking due to vibration. The engine in the i8 is definitely half of the same engine that's in the M3 though.
dknollRX7 it is not. Completely different platforms. The i8 uses the modular platform while the m3 uses the old 6 cylinder platform.
+Akash Hegde I meant to say definitely NOT*. Should have double checked before I hit send. I work at a BMW dealer and I'm the only one certified to work on the i8. I can attest it's a completely different engine from the M3.
Its so quiet that the speakers need to produce noise so pedestrians can hear it, lmfao...
It would be interesting to see laser headlights for U.S. bound i8.
