The beamng seems like it does not simulate cold starts in normal conditions like -20 or -40

Wow, never seen -268.5 degrees celsius in Utah, before...

5:27 physics: -280°C? That's illegal

At the -60 degree Celsius mark, or -76 Fahrenheit I guarantee the 2 diesels would never be able to start without some serious help, normal 15w-40 oil gets so thick that I'm not entirely sure the starter could even turn them over cold without oil heaters or block heaters

Every abandoned car finder:

Next test: set the temperature to 90°C, more or less the average temperature of an engine running.

Off course the car can’t start. You went bellow the lowest temperatire known of physics

BeamNg is missing a proper good quality smoke physics. I mean they've reached pretty high peak when it comes to damage simulations and physics, I'd love them to see go more into details, brake glow, sparking brakes, rainy conditions, diesel smoke, screamer pipe setups with proper sounds, etc

Surprising they have a point they won't run but didn't set it anywhere near to realistic, maybe somebody missed a decimal point.

I can assure you , that truck wouldnt have started at minus 20 without being plugged or having the glow plugs played with

Cold start, rev it immediately

Gotta love that very rough idle on the Semi-truck at the end.

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

it's not the starter, neither the battery... U FROZE THE FUEL TO CLUMPS

5:28 ah yes,in the world of BeamNg,there's no such thing as absolute zero(-273.3°c)

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 :(

-280°C? There is no such thing. The absolute zero temperature is -273.15°C or 0°K.

Nobody: My computer fan: 7:27

Set a low environment temp and run without radiator. Also, you may test the picollino, since it's aircooled Edit: Actually i did that myself, it doesn't matter the temp, it seems that the cars won't start and run because they can't get enough air. If you set it to -270ºC and start to climb, there will be an altitude that the engine will refuse to rev up and will "lock" itself, it seems that Beam has a air density simulation that gets all haywire with those extreme temps. I went as far as running the engine only on nitro haha

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.

Lol I wish my car starts that easy in minus 20 degrees

Hmm..... temperature on Beam bugged, or maybe you'll need to see the temperature of the engine/oil because you might have to let them sit after adjustment..... because I live in North Dakota..... Once it hits 0°F and you don't have a block heater things start to not want to start, -10°F after sitting for 3hrs and you'll be sluggish starting, -20° and no block heater or battery plugged in? It's either going to have extremely limited voltage for starting, or your oil is so viscous you're struggling to turn over. I've had vehicles that won't start at -10°F, -30°F is usually where they don't want to do anything if they've sat for over an hour with no assistance.... everything else at -30° is great too, infotainment systems struggle to show their screens, stuff is tight and doesn't want to move....so yeah temps definitely bugged on Beam, or they need to "soak".

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

7:09 that was like a dyno test xdd

This shows that Beamng completely fails at simulating air temperatures.

If you have the car on a downhill and you starting roll, the engine doesn't froze on start up and Will work even at neptunian temps 😁

already at -60 c none of these vehicles would start

8:57 Maybe you found the low temperature limit but judging by the sound of the truck engine, these engines seem to find it difficult.

At -60° diesel is just wax. Nothing would work and at 0 K a lot of metal parts would break like glass under stress.

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 like how condensation billows from the exhaust at lower temperatures.

I find it hilarious that the old car seemed to run slightly better than the others, despite it having a carburetor. Funny!

Interesting how even Beam understands how minimum temperature is -273

It's not realistic. Even in -10°C when you start a car, it idles almost in 2k rpm. Because the automatic choker goes on.

Love how the desert and the weather still looks warm 😂

Ok there is no way the Diesel engines and the carbureted engines would’ve started that easy BeamNG lmao

how do i put the Temperature down i wanna try this too on my own

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.

Temp: almost absolute zero Beamng: I see absolutely no reason why it shouldn’t start

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.

It's physically impossible for the gas engines to work under -100 since the fuel would've frozen already

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

the truck starting sounds like someone struggling to breathe lol

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

Let alone that the gasoline would instantly freeze on - 270

Very cool video Dude, but how you change the temperature!?

How to change temperature? Plz i neee to know :(

PLEASE MAKE A TUTORIAL ON HOW TO CHANGE TEMPERATURE ITS NOT WORKING FOR ME

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.

Just saying the only vehicle that would have a hope of starting at -60c would be the efi gasser but that’s pushing it

Impressive, very nice, let's see Paul Allen's diesel.

*-100 degrees* Crickets: ctrrrrrrrrrrric

7:17 had a 2 fast 2 furious moment 💪

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.

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.

Any vehicle wouldn't start at -100 C but this was entertaining lol

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!

the exhaust has visible smoke once it gets to freezing temperature. cool detail.

5:26 Duuuude, u can't reach -280C. The lowest possible temperature is exactly -273.15C or -459.67F... Science! (:

no country has such tempratures

-100 degrees start up in a desert map, ironic

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?

What a video. Its just always the same engine start

The limit is -271 if enemy further engine will lock up AND you need to respawn the car and then it will affect it

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.

how to set the temperature down?

Actually kind of disappointed the diesels didn't have any issues until impossibly cold

BeamNGdrive cars stop starting when the temperature is lower than absatute zero (-273,15°C), disel is frozen at -60°C.

how do you actually change the temperature in beam?

5:27 when every rule of physics goes too far, but not too far like temperature.

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

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.

What's cursed is that he made it cold in the desert.

I've played this game for years and didn't know you could change the temperature

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

This is awesome video I'd love to see how hot it can get before it won't start anymore

Lol the fact you did it in the utah map

-273 is absolute zero where particles no longer move lmao

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)

Cold start....in the fucking desert... Are you fucking kidding me

It would be cool to see the cars actually drive in their minimum temperature limits!

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

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.

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.

importance of 0.5 degree lol

The fact is that cold in a desert is all sorts of janky

Wow, didn't know that was a thing! Edit: I'm first???

Goes below absolute zero of -273.15C... guess we found the cut off after all atoms in existence stop moving.

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

did you turn off pre heat engine?

I hope my 2007 Skoda octavia 2.0 Tdi would start that well too in -200°C 😂

Did you have to quick turn each of them off after spawning? Or were you some how able to get them to spawn cold and dark?

Man VS Car in Arctic weather (top gear). A diesel engine dont work under -17ºC... no -260 xD

how do you change the temperature? wanted to do this for myself a long time but couldn't find an tutorial

How about extreme hot start ? Or something like that

In this case -100 degrees ain’t exactly doing shit because those exact same cars are starting like nothing 😂😂

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 love your vids keep up the good work
