My guess: Older/well worn cars lose a few horsepower from their engine's output from less compression, more friction, etc.
... OP, brake fade is a temporary condition caused by higher than designed temperatures vaporizing the pads. This feature would be included in the brake thermals update the devs are probably either working on, or will start soon. What I assume you are suggesting is brake rotor and pad wear, which would be nice along with a decrease in engine efficiency but only for campaign (when it comes out) and only if you don't do the proper maintenance on your car. See, in freeroam, you simply don't drive long or far enough for part wear to become a problem warranting attention.
That's something that bugs me a little, it also applies to the fuel comsumption and, to a lesser extent, thermals. It would be nice to have UI Apps to set things like brake wear, fuel level, specific internal damage in general and to a lesser extent brake fade, that would take too long to achieve in an average free roam session.
except that can take many many many thousands of miles. I had a focus on 152000 miles that still pulled near bang on the factory 0-60 time which would suggest negligible power loss due to age/wear. You arent going to be doing 152000 miles in BeamNG
would still take more than a few days of *solid* driving to wear the engine. Unless you have no oil, at which point engines already get damaged in game
It would take a few years of solid driving to get any form of HP loss....as for brake fade....thats dependant on how you drive the car and how you use the brakes....
You need to understand one thing. This game is realistic. Cars in real life don't fade off and start losing Horsepower within 100 miles of usage. Or one gas tank. If you drove the car for atleast 10,000 miles then I'd expect some wear and tear. But who wants to waste their time on that. Right?
Actually, you would only get wear and tear at 10k if you were ridiculously hard on the engine, like running the car with almost no coolant or oil. If the oil is changed regularly and the owner makes sure the engine is running properly, the block could last a million miles or more.
Horsepower lose seems a bit unnecessary, but brake fade is a MUST. Give us a reason to use race brakes, because right now any ABS brakes will out perform racing brakes, plus cars with tiny drum brakes have very decent stopping distances compared to modern cars with large rotors which, while better, have mediocre braking performance.
Yes you will. Brake fade is distinct from brake wear. Brake fade is caused by the brake pads and rotors heating up too much and losing effectiveness. This usually happens during racing or while traversing down mountainous roads, two situations that are fairly easy to find in Beam. Brake wear is a much longer term condition due to abrasion of the pads and rotor over time.
Oh yes you can cause brake fade very easily. Dinky, poorly cooled drum brakes would fade noticeably in one hard stop. Disk brakes cool better, they'd take a whole lap around the track before they start fading, but for track driving, it's very noticeable.
Ever driven? I assure you that in BeamNG you can easily drive hard and fast enough to cause fade, it would be possible within a single lap of ECA perimeter. Fade and wear arent the same thing.
Not sure if fading brake pads/drums are a good idea due to the fact that in real life you can drive like 200k km without replacing them. However drum brakes can/will have some issues after they warm up enough but sadly very few vehicles have them as primary brakes. I think.
