A guide to making rally cars. in my experience playing Dirt Rally 2.0 and Beam NG
 
 

Intro

Automation isn’t really made for building rally cars. You can make a pretty good approximation but it lacks things like toe adjust (can be done in Beam), individual gear tuning and proper tires. these might come later but for now we have to make do.
 
Rally in Beam NG is hard… Really hard, a single mistake and your car will never drive another meter. so its almost more important to make a car drive able than to make it fast. Both is best.
 
 
 

Drivetrain

Engine tuning is very important for drive ability. A poor power band can make a car stall in hairpins.
 
 
NA engine’s are pretty easy. Just keep the max torque at 1/2 to 2/3 of max rpm and tune the exhaust for max torque instead of power (usually one tick down). Also throttle response is good, so use a light bottom end and quite rich fuel.
 
 

 
Turbo’s are more difficult. Lag can make the car stall easily. to get a good powerband use a low cam profile and high boost. make the compressor big enough so the turbo doesn’t overheat and the turbine as small as possible without surging. AR should be so it just encompa*ses the power band. the low cam profile is crucial to stop the turbo from overheating.
 
 

 
 

 
The gearbox is just as important as the engine. for rally cars wheelspin is good, it enables you to powerslide and it gives more traction on gravel. so make the gears short. on most tracks you will never exceed 180 kph so going above that is pretty useless. if you have low power go even lower id say set max speed at 220 kph at 400 hp to 120 kph at 100 hp but it kind of depends on your engine. the worse your powerband is the shorter your gears need to be, The graph should have a flat line at the top, big gaps will make the car transition from wheelspin to traction and back, this will at best stall the car and at worst send you flying of the track. if you cant get this to work tune the engine less aggressively
 
 
 

Tires

I tested all promising tire compounds in beam on several surfaces, From hard long life, Chunky offroad and All terrain was All terrain the obvious winner it pulled the most G on all surfaces in all directions. hard long life was equal on tarmac but a lot worse on light and heavy gravel, sand, gra*s or mud. chunky offroad did a bit better in mud but worse everywhere else. on Italy gravel hillclimb 1 chunky was 30 sec slower than all terrain (driver error was 3 sec over 3 runs each) it also pulled 0.8 g compared to 0.9 in all directions except braking, here it was 0.8 compared to 1.2
 
 
the tires work best with narrow profile with a high tire wall. 15 inch 630mm by 160 mm all round on my AWD Group B car
 
 
I also would not give the wheels a big offset. it doesn’t really help performance and tucking them in protects the suspension from collisions, you also see this on real cars.
