Two things i'd like to suggest. Firstly to do with engine behaviour. When engines are not under load (neutral or clutch in) engines will rev up incredibly quick (and there isnt really a issue there), but will decelerate extremily slow. this means driving manual is a bit weird and generally makes the game seem a bit weird. Second is to do with automatic transmission behaviour, which i have two suggestions for. Firstly, when you engage it into gear it will realistically start moving without throttle. however, it moves quite a bit faster than a real automatic creeps. torque converters wont make cars creep quite that fast. ontop of that, theres so much drive force from the idle creep that some cars cannot stop with brake fully on. I'm sure anyone whos driven a automatic car before will know it only takes very light brake pressure to stop the car from creeping. Secondly, when you switch between gear mods in real automatic (D, 2, 1, N, R) the transmission will not check what gear it was previously in. what i mean by this is when i switch from 1 to 2, then to D the transmission will not stay in 2nd or shift up to third, it will go straight to 1st gear when D is engaged. the engine over revs, car spins out, and it takes quite a while to switch up to 3rd. its just a ugly situation. If there was a script added to check what gear it was previously in when you select D, life woulld be better.
I noticed a couple of days ago that slamming it in to first gear while going 80+ did not decelerate the car nearly as much as I feel it would. The wheels gave a short chirp and the speed dropped from 80 ish down to 60 and I was happily holding that speed for ages without my foot on the throttle. The top speed of the car in first gear is about 30, so i would expect the speed to drop down to 30 quite quickly. Though I would expect the engine or gear box to explode if I did that in real life.
The automatic tranny behavior is a little derpy right now, its being worked on and has actually improved since first release. On the engine braking thing: Slamming into 1st at 80mph would blow your engine, so dont be surprised that it doesnt brake that well. Under normal conditions, the engine braking works quite well
I disagree with above, engine braking for the most part is unrealistic. Furthermore, both the manual and auto tranny setups need work on realism. The manual's clutch engages fully at 1-2% from 100% pressed in (IIRC, RoR had this issue). The auto does require a heck of a lot of brake force to be stood till in D.
the clutch is a bit grabby but it hasnt bothered me too much, but the keeping still in D on autos is just silly lol. all it needs is to have the trans engage itself A LOT less
A torque converter is basically a clutch that's slipping all the time. You could simulate the behavior by having the clutch partially engaged at all times except WOT or top gear (which then it'd be fully connected, simulating a lock-up converter), with it never fully disengaging (except with the transmission in Neutral). You'd have to model clutch slip for the "automatics" to be much more linear than an actual clutch but that shouldn't be hard for someone that can do all this other programming. The hard part would be simulating a parking pawl. Putting an automatic in Park doesn't lock the brakes, it locks the driveline. That means wheels not connected to the transmission would turn freely.
The devs know about this, they've stated this in the pre-race update blogpost. It's a temporary setup because a parking pawl hasn't been programmed yet.
I want to agree with op. The engines needs some more love. One of the most odd behaviour is, that it only needs 15% - 20% throttle to let the engine spin up to max rpm slowly (without load). Maybe modern cars have a controller in between, but in fact the throttle - rpm ratio is much more linear with real cars. What i noticed from my Pugeot irl, it is around 75% throttle to actually reach maximum rpm. It also holds the rpm much more. Maybe an exponential engine self friction will solve that. I would also appreciate i we get some realistic turbo charger. ATM selecting the part just changes the static rpm - torque table and fully leaves out spinup / spindown time.
