That damages the engine because the oil is too thick to get into small crevices and the gaps between parts are too large due to thermal expansion/contraction.
At minus -60 you could tell the game isn’t realistic the diesels seemed to start up within the first few cranks, at that temperature a diesel definitely wouldn’t be starting that quickly

There is one feature missing in beamng that would drastically improve realism to me, and that is thermostat. Engines , when starting cold, IRL, increase the RPMs until achieving working temperature. The increase is not dramatic, for my 2007 Ford Focus (piece of trash) it would be ~100-150 RPM higher idle. About 5 minutes idling in winter (~15 degrees centigrade) and the engine is warm and idle drops. My carbureted scooter has an electric enricher which is composed of a tiny hole that is open inside the carburetor, and the enricher is a plastic covered stick like shape, sitting outside the carb, with wax inside it, covering a small tube that plugs right into that hole. A cable that is connected to the AC circuit is heating the wax, which in turn pushes the metal pin, that plugs the "extra fuel" hole in the carb. The AC circuit is powered only when the engine is powered (and generating power by stator), and not related to the 12v DC battery. I need those things in beam :(
I totally noticed that. I live up north so cars idle high when starting up until it warms up. Also they should add a feature that depending on grill size cooling efficiency goes up and down. This means for extreme cold they could add a car bra to it.

The real problem is that -280°C is less than 0° K, so it’s simply impossible to do, every molecule is absolutely static for thermodynamic’s laws and that’s why engines destroys as soon as you start them Moreover, I think beamNG let starts cars because you start them with engine already heated and only few seconds after changing the temperature… You should wait 10 minutes between every change and then try again
Nice, just keep in mind that anything below - 273 doesn't make sense since the absute zero in temperature is at - 273 degrees Celsius. Anything below that is impossible to achieve or exist.
yeah, at -265C water would be rocksolid… and the atmosphere would start to liquidify / or start fall as snow :) all pipes in the car would be ruptured, batteries would have no charge in them and probably ruptured too… those cars would not go anywhere :)
That's actually wrong. If you set the temp in the game, let's say -10C and fast forward game time you'll see that cars take much longer to start. I remember watching a video about that; some youtuber tries to start cars around that temp in the game and they take a lot of time to start. I think what's happening here is although air temp is low, cars are not yet cold enough to have problems starting. Wait for a long enough time and try this again, you'll see different results.

The Beam devs have done most of the core pieces so now they're visiting the smaller things that add even more realism to an already awesome game.
Diesel is rated for -40C in cold climate countries but sure it’s the near 0 Kelvin where particles on the atomic level stop moving that causes issues with starting
Hell nah at -20 celsius most vehicles would struggle with cold starts at least a little. Where i live in the midwest we’ve seen as low as -35 celsius and i can say with certainty that almost every vehicle would struggle starting especially diesels if the fuel hasnt been treated so it wont turn to gel.
Normally Winterdiesel I think freezes at -40 degreese and gaoline is a bit higher... from what Ive heared. Seems like BeamNG doesnt simulate Temperatures very well. But to all: BeamNG is still in the Beta Phase... But I hope they add VR Support in some of the next updates...
I think what's happening here is although air temp is low, cars are not yet cold enough to have problems starting. Wait for a long enough time and try this again, you'll see different results.
I think the only reason the cars had trouble with -270 temps is because the air density was severely changed. The required fuel from the injectors was way out of the scope of what they could provide so you were running way too lean and the engine efficiency went to crap. If you look at the airspeed indicator in an app you can see that they do model the air density. If you set the temp below 15c and drive at sea level, the airspeed will read higher than the ground speed, varying depending on how much lower than 15c you go due to increased air density flowing over the "sensor". Temps above 15c have the opposite effect.
I live in the desert and literally just got six inches of snow today, might hit single digits tonight even lol. Not all deserts are near the equator like the Sahara, and often times they're quite cold come wintertime.
something i have discovered while playing with altitude and temperature in that game is that when you lower the temperature the air density in higher altitudes falls dramatically, and as far as i could notice only the air density took an effect on how the engines ran , so at -200°C but at altitude 0 the cars ran like normal
having started cars in -45c, naw, the carb would be fine too as long as the fuel is flowing, just gotta hope the choke does not freeze up nor that the carb ices up before it can heat up enough to keep it melted.
@@chubbysumo2230 there’s a pretty big temperature difference between -45 and -60c I doubt a carbureted car would fire without a starting aid you just can’t control the fuel mixture as precise and fast as efi
My 10 year old MPFI Hatchback has enough brains to idle at 1500-2000RPM during cold starts. And my Diesel SUV would guaranteed not start at less than freezing, as Diesel clumps and turns into gel at low temperatures without additive.
Living in a cold climate I can confirm the test was not accurate. No I didn't really expect it to be but I was hoping it would have been a little better than this.
Unlike water, gasoline does not freeze at zero degrees Celsius, but only at around minus 60 degrees. Diesel begins to flocculate at around minus 22 degrees.
While I haven't seen temps anywhere near -100° F out here in the desert, it's gotten down to -20 around me plenty of times. They aren't just always hot barren wastelands.
I find this hard to believe I had to start my car once at -27 and everything was so slow and it took a while to start. It’s a gas car. So these cars starting at -250 and firing up no problem seems very unreal
280 below is the limit since -273.15'C is Absolute Zero. Even at -100'C, the tyres ought to be down around 11 psi and somewhat flat-looking, then at -200'C they should be 21 psi down and thus at around only 11 psi, basically flat at that point, but with proper tyre extreme-low-temperature damage simulation the tyres would crack and break apart at around -60'C since rubber loses elasticity at that temperature and the first light-moderate bump would shatter the tyre. Likewise, the battery, being lead-acid in basically all cars still just a different internal cell makeup, lose 35% of their cranking power at 0'C and by -18'C lose 60% of their cranking power. Thankfully, even if reduced in amp-hours charge, they have a lower coulombic efficiency and thus warm up a little bit under a cranking load, which is why a successful cold start has a slow crank that gets a bit faster and then the first combustion strokes happen to make it faster until idle speed is reached and the engine becomes self-sustaining as the throttle opens up to cold-high-idle speed. One thing of note, in extreme cold it would be cool if just having your lights on would make the difference between running out of electricity under starting or actually making it to idle. At around -40'C is when the older cars' fuel lines should start to freeze and make starting nearly impossible, especially problems with the carburetor jets both with partially frozen fuel and a very lean fuel mix from the cold, dense air. Maybe -60'C for newer cars would be okay due to modern fuels but it would have fuel problems with partly frozen gas being shot out of the injectors, little frozen crystals in the gas of the parts like Nonane at -50'C and Octane (the main component of gasoline beside Heptane's -91'C) at -57'C. Gasoline actually starts to turn into a gel at -100'C and by -200'C its all solid flammable ice. At -35'C is when diesel fuel begins to turn to gel so that's a problem trucks have had to deal with for decades. In terms of the oil, higher performance car engines ought to have more trouble starting since their race oils have a worse cold weather rating but a better high temperature rating, they are designed for high revs and high throttle, while economy cars use lighter oils that get too viscous when hot but they stay viscous and not gel-like in really cold weather, cold enough that the battery is the primary concern. On the subject of electric cars, Lithium-ion stops charging at full speed at 0'C, so regen braking starts to fail in the winter unless you're burning power to keep the cells warm. Some cells can go as far as -4'C and do full charge rate, but its inadvisable due to permanent cell damage below those temperatures, which Beam could simulate as a damage value reducing cell maximum charge as well as current charge level in concert with each other. Edit: By around -20'C the lithium batteries have lost about half of their discharge rate and capacity. By -40'C they just stop, like they chemically stop working from the temperature/charge/discharge graphs I've been able to find. Electronically they would just stop discharging when the cells go below -20'C or if they go above 60'C. By around -30'C the battery is down nearly 70% of its full power, and as it gets colder you'd notice easily the decreasing power output as the acceleration gets slower and slower until the car stops being able to overcome rolling resistance and the ever-increasing gear-reducer oil thickness, that is assuming the battery protection could be disabled via a car setup option or the min/max temperature values adjusted, get to see the battery explode when you overheat it from repeated drag races without a cooling break. That'd be fun. For all types of engines, a general temperature that the transmission oil freezes at would be around -90'C (that is too thick for the internal pump to even move it), so electric cars would fail to move or move very poorly at those temperatures presuming their batteries can even hold a charge (not likely), gas engines would maybe creep forward if you can work the clutch properly or just stall the engine in an auto (presuming the engine can even run with nearly gelled gas), and a diesel wouldn't even start at all but presuming it could it would creep slowly or wreck the gearbox from the high engine torque in the low-end. Differential fluid doesn't really seem to freeze (Google has literally no data available like WTF) but around -45'C is when it's too thick to drive with. An optimal mixture of 70% antifreeze to 30% water for the coolant freezes at -65'C, or for a 50/50 mix at -37'C, its all quite interesting the stuff that can go into this. Funnily enough, power steering fluid freezes at the surprising temperature of -3'C because its ethylene-glycol based, like how pure antifreeze alone freezes at -17'C but when mixed 70/30 with water that goes down to -65'C, power steering fluid has a high freezing point, though since the pump is right on the engine block it warms up very fast so its not really a problem. At -103'C is when the A/C refrigerant solidifies, with it liquifying at -26'C. Seriously, cars are interesting shit and I love them.
I think the effect of temperature is not properly simulated. There's no way the engine from a semi will start at -250 ºC like it's a summer day. Then they lock up all of a sudden. Also, it allows you to set temp to "-280 ºC" which is undefined. Minimum temperature in the universe is 0K (around -273 ºC)
Cool vid but as for the diesels very inaccurate, depending on the additives diesel can start to gel at about -10c, at -100 it would be like vaseline and the vehicle would not start, just watch cold diesel starts from places like russia and look at the struggle there diesel cars have starting at -20
you should've warm the engines to working temperatures to see if there is any difference on that lowest possible temperature between cold and warm engines
At -280C the laws of physics no longer exist, given -273.15 is absolute zero, I wonder if the game was just following along on that basis and that's why things worked at -270 but not -280.
I dont agree to the cold starts but the only reason i can think of the power getting weaker as temp drops is air to fuel getting lean due to air getting more dense
Next time, let the cars get down to temperature. None of these vehicles should have started at -100C, but just because the air is cold doesn't make other things immediately cold. You need to let things get down to temp.
There is a video of people living in Yakutsk( spelling wrong maybe) temperaturew around -40 degrees celsius, and they have a diesel jeep. They have to unfreeze the engine oil. It's not simple like here in this game.

I wouldn't even start.
I find it hilarious that the old car seemed to run slightly better than the others, despite it having a carburetor. Funny!
Temp: almost absolute zero
Beamng: I see absolutely no reason why it shouldn’t start
Diesel is rated for -40C in cold climate countries but sure it’s the near 0 Kelvin where particles on the atomic level stop moving that causes issues with starting
Hell nah at -20 celsius most vehicles would struggle with cold starts at least a little. Where i live in the midwest we’ve seen as low as -35 celsius and i can say with certainty that almost every vehicle would struggle starting especially diesels if the fuel hasnt been treated so it wont turn to gel.
Normally Winterdiesel I think freezes at -40 degreese and gaoline is a bit higher... from what Ive heared. Seems like BeamNG doesnt simulate Temperatures very well. But to all: BeamNG is still in the Beta Phase... But I hope they add VR Support in some of the next updates...
I think what's happening here is although air temp is low, cars are not yet cold enough to have problems starting. Wait for a long enough time and try this again, you'll see different results.
-268.5°C. Air gases have frozen into solid form but the engine still starts. Logic.
At -60° diesel is just wax. Nothing would work and at 0 K a lot of metal parts would break like glass under stress.
Love how the desert and the weather still looks warm 😂
I think the only reason the cars had trouble with -270 temps is because the air density was severely changed. The required fuel from the injectors was way out of the scope of what they could provide so you were running way too lean and the engine efficiency went to crap. If you look at the airspeed indicator in an app you can see that they do model the air density. If you set the temp below 15c and drive at sea level, the airspeed will read higher than the ground speed, varying depending on how much lower than 15c you go due to increased air density flowing over the "sensor". Temps above 15c have the opposite effect.
Ok there is no way the Diesel engines and the carbureted engines would’ve started that easy BeamNG lmao
PLEASE MAKE A TUTORIAL ON HOW TO CHANGE TEMPERATURE ITS NOT WORKING FOR ME
th-cam.com/video/QKhBEBGSEjE/w-d-xo.html here, at second 30... he shows it
Impressive, very nice, let's see Paul Allen's diesel.
It's physically impossible for the gas engines to work under -100 since the fuel would've frozen already
Interesting how even Beam understands how minimum temperature is -273
well not really, because air would condense into a liquid right around -200.
" even beam " well... the car will probably not even start at -50
*-100 degrees*
Crickets: ctrrrrrrrrrrric
The fact is that cold in a desert is all sorts of janky
I live in the desert and literally just got six inches of snow today, might hit single digits tonight even lol.
Not all deserts are near the equator like the Sahara, and often times they're quite cold come wintertime.
the truck starting sounds like someone struggling to breathe lol
no country has such tempratures
Let alone that the gasoline would instantly freeze on - 270
Very cool video Dude, but how you change the temperature!?
Press F11, pick the theLevelInfo object in the Scene Tree and search for the temperatureCurveC entry.
@@ForgottenMustard Thank you very much, i waiting for more cool videos!
How?
At -68 no cars would start that easy
7:17 had a 2 fast 2 furious moment 💪
something i have discovered while playing with altitude and temperature in that game is that when you lower the temperature the air density in higher altitudes falls dramatically, and as far as i could notice only the air density took an effect on how the engines ran , so at -200°C but at altitude 0 the cars ran like normal
So you mean we need to drive sea level to on -200C° to drove normally.
5:27 when every rule of physics goes too far, but not too far like temperature.
What a video. Its just always the same engine start
the exhaust has visible smoke once it gets to freezing temperature. cool detail.
Just saying the only vehicle that would have a hope of starting at -60c would be the efi gasser but that’s pushing it
having started cars in -45c, naw, the carb would be fine too as long as the fuel is flowing, just gotta hope the choke does not freeze up nor that the carb ices up before it can heat up enough to keep it melted.
@@chubbysumo2230 there’s a pretty big temperature difference between -45 and -60c I doubt a carbureted car would fire without a starting aid you just can’t control the fuel mixture as precise and fast as efi
how do i put the Temperature down i wanna try this too on my own

F11
a -50° gradi in russia devono tenere sempre in moto il motore perché se no il monoblocco si congela insieme ad olio e acqua e si spacca tutto!
My 10 year old MPFI Hatchback has enough brains to idle at 1500-2000RPM during cold starts. And my Diesel SUV would guaranteed not start at less than freezing, as Diesel clumps and turns into gel at low temperatures without additive.
Living in a cold climate I can confirm the test was not accurate. No I didn't really expect it to be but I was hoping it would have been a little better than this.
The old lady down the street warms her car up just like that on cold days.
How to change temperature? Plz i neee to know :(
Press F11, pick the theLevelInfo object in the Scene Tree and search for the temperatureCurveC entry.
@@initialyeet3951 Okay, but what's your point?
@@initialyeet3951 Why does it matter? Most likely he is a child.
@@initialyeet3951 your name has yeet in it...
@@ForgottenMustard can u make a video on how I can't figure it out tbh
Should do an extreme heat start video just to see at what point they can't cool themselves.
How do you adjust the temp like that?
I'm probably late, but you can find that in environmental controls
I love your vids keep up the good work
BeamNGdrive cars stop starting when the temperature is lower than absatute zero (-273,15°C), disel is frozen at -60°C.
Actually kind of disappointed the diesels didn't have any issues until impossibly cold
Any vehicle wouldn't start at -100 C but this was entertaining lol
Unlike water, gasoline does not freeze at zero degrees Celsius, but only at around minus 60 degrees. Diesel begins to flocculate at around minus 22 degrees.
5:26 Duuuude, u can't reach -280C. The lowest possible temperature is exactly -273.15C or -459.67F... Science! (:
My toilet at 3 AM gets colder than that
What's cursed is that he made it cold in the desert.
I'd kind of like to see if the performance of an electric vehicle is altered in the cold as it is in real life.
It would be cool to see the cars actually drive in their minimum temperature limits!
-100 degrees start up in a desert map, ironic
While I haven't seen temps anywhere near -100° F out here in the desert, it's gotten down to -20 around me plenty of times. They aren't just always hot barren wastelands.
I find this hard to believe I had to start my car once at -27 and everything was so slow and it took a while to start. It’s a gas car. So these cars starting at -250 and firing up no problem seems very unreal
Almost as if its a game
280 below is the limit since -273.15'C is Absolute Zero. Even at -100'C, the tyres ought to be down around 11 psi and somewhat flat-looking, then at -200'C they should be 21 psi down and thus at around only 11 psi, basically flat at that point, but with proper tyre extreme-low-temperature damage simulation the tyres would crack and break apart at around -60'C since rubber loses elasticity at that temperature and the first light-moderate bump would shatter the tyre. Likewise, the battery, being lead-acid in basically all cars still just a different internal cell makeup, lose 35% of their cranking power at 0'C and by -18'C lose 60% of their cranking power. Thankfully, even if reduced in amp-hours charge, they have a lower coulombic efficiency and thus warm up a little bit under a cranking load, which is why a successful cold start has a slow crank that gets a bit faster and then the first combustion strokes happen to make it faster until idle speed is reached and the engine becomes self-sustaining as the throttle opens up to cold-high-idle speed. One thing of note, in extreme cold it would be cool if just having your lights on would make the difference between running out of electricity under starting or actually making it to idle.
At around -40'C is when the older cars' fuel lines should start to freeze and make starting nearly impossible, especially problems with the carburetor jets both with partially frozen fuel and a very lean fuel mix from the cold, dense air. Maybe -60'C for newer cars would be okay due to modern fuels but it would have fuel problems with partly frozen gas being shot out of the injectors, little frozen crystals in the gas of the parts like Nonane at -50'C and Octane (the main component of gasoline beside Heptane's -91'C) at -57'C. Gasoline actually starts to turn into a gel at -100'C and by -200'C its all solid flammable ice. At -35'C is when diesel fuel begins to turn to gel so that's a problem trucks have had to deal with for decades. In terms of the oil, higher performance car engines ought to have more trouble starting since their race oils have a worse cold weather rating but a better high temperature rating, they are designed for high revs and high throttle, while economy cars use lighter oils that get too viscous when hot but they stay viscous and not gel-like in really cold weather, cold enough that the battery is the primary concern.
On the subject of electric cars, Lithium-ion stops charging at full speed at 0'C, so regen braking starts to fail in the winter unless you're burning power to keep the cells warm. Some cells can go as far as -4'C and do full charge rate, but its inadvisable due to permanent cell damage below those temperatures, which Beam could simulate as a damage value reducing cell maximum charge as well as current charge level in concert with each other.
Edit: By around -20'C the lithium batteries have lost about half of their discharge rate and capacity. By -40'C they just stop, like they chemically stop working from the temperature/charge/discharge graphs I've been able to find. Electronically they would just stop discharging when the cells go below -20'C or if they go above 60'C. By around -30'C the battery is down nearly 70% of its full power, and as it gets colder you'd notice easily the decreasing power output as the acceleration gets slower and slower until the car stops being able to overcome rolling resistance and the ever-increasing gear-reducer oil thickness, that is assuming the battery protection could be disabled via a car setup option or the min/max temperature values adjusted, get to see the battery explode when you overheat it from repeated drag races without a cooling break. That'd be fun.
For all types of engines, a general temperature that the transmission oil freezes at would be around -90'C (that is too thick for the internal pump to even move it), so electric cars would fail to move or move very poorly at those temperatures presuming their batteries can even hold a charge (not likely), gas engines would maybe creep forward if you can work the clutch properly or just stall the engine in an auto (presuming the engine can even run with nearly gelled gas), and a diesel wouldn't even start at all but presuming it could it would creep slowly or wreck the gearbox from the high engine torque in the low-end. Differential fluid doesn't really seem to freeze (Google has literally no data available like WTF) but around -45'C is when it's too thick to drive with. An optimal mixture of 70% antifreeze to 30% water for the coolant freezes at -65'C, or for a 50/50 mix at -37'C, its all quite interesting the stuff that can go into this. Funnily enough, power steering fluid freezes at the surprising temperature of -3'C because its ethylene-glycol based, like how pure antifreeze alone freezes at -17'C but when mixed 70/30 with water that goes down to -65'C, power steering fluid has a high freezing point, though since the pump is right on the engine block it warms up very fast so its not really a problem. At -103'C is when the A/C refrigerant solidifies, with it liquifying at -26'C.
Seriously, cars are interesting shit and I love them.
I think the effect of temperature is not properly simulated. There's no way the engine from a semi will start at -250 ºC like it's a summer day. Then they lock up all of a sudden. Also, it allows you to set temp to "-280 ºC" which is undefined. Minimum temperature in the universe is 0K (around -273 ºC)
-273 is absolute zero where particles no longer move lmao
Cold start....in the fucking desert... Are you fucking kidding me
This is awesome video I'd love to see how hot it can get before it won't start anymore
Temperature in BeamNG doesn't affect the start of engines. Engine brake shows up only if you go under -273 C which is 0 K and game breaks somehow
I subscribed, but how do you get BeamNG drive on your pc? Same with that nice looking gauge
Cool vid but as for the diesels very inaccurate, depending on the additives diesel can start to gel at about -10c, at -100 it would be like vaseline and the vehicle would not start, just watch cold diesel starts from places like russia and look at the struggle there diesel cars have starting at -20
you should've warm the engines to working temperatures to see if there is any difference on that lowest possible temperature between cold and warm engines
how to set the temperature down?
At -280C the laws of physics no longer exist, given -273.15 is absolute zero, I wonder if the game was just following along on that basis and that's why things worked at -270 but not -280.
I hope my 2007 Skoda octavia 2.0 Tdi would start that well too in -200°C 😂
ELECTRIC/TESLA BOIS:
WE DON'T HAVE SUCH WEAKNESSES
Yes you have, lol
how do you actually change the temperature in beam?
Lol the fact you did it in the utah map
Beam should've put v8s in the new "BMWs".
I've played this game for years and didn't know you could change the temperature
I dont agree to the cold starts but the only reason i can think of the power getting weaker as temp drops is air to fuel getting lean due to air getting more dense
Most cars also generate zero heat at idle. Ive left cars on for 20 or 30 minutes and still not warmed up
Next time, let the cars get down to temperature. None of these vehicles should have started at -100C, but just because the air is cold doesn't make other things immediately cold. You need to let things get down to temp.
Man VS Car in Arctic weather (top gear). A diesel engine dont work under -17ºC... no -260 xD
I literally have the same video concept and I still editing it but you make it first
anyway Good job
There is a video of people living in Yakutsk( spelling wrong maybe) temperaturew around -40 degrees celsius, and they have a diesel jeep. They have to unfreeze the engine oil. It's not simple like here in this game.
Pretty sure they fixed it in some update because i saw people do this in newer versions and cars seemed to start worse
