(I've only read the first 5 and the latest 15 pages so forgive me if I repost some stuff)
- The Lamborghini Aventador's rear spoiler has multiple levels of tilt for increasing speeds.
- The Peugeot 307 CC has the driver animation for shoving the stick forwards into reverse gear. The Dodge Challenger SRT8 and Volvo C30 also have such animations and even have the driver using the respective autostick and tiptronic functions unlike the Peugeot. The electric/hybrid Tesla, Leaf and Prius also have driver arm animations, though the first doesn't have the lever moving from D to R.
Conversely, the Mustang GT and SL55 AMG have no animation whatsoever, despite the latter having a similar autostick function to the Dodge. As a whole though, cars that utilize paddle modes will not be able to shift the lever or press buttons to activate reverse gear.
- The premium Minis are among the few premium sporty/performance cars that are correctly specified as having open differentials. The R35 GT-R correctly has an open front diff as well, though the center and rear end seems to be a normal LSD rather than the fancy torque biasing ATTESA system.
Perhaps this is partly why only the Evolutions have the correct (though artificial ESP-ish feeling as wheelspin feels too controlled) torque biasing AYC-effect. The Evolution X does have a front LSD unlike a R35. Not really sure about the older Evos and R32-R34 GT-Rs though...
- The premium Toyota Vitz uses a CVT but has simulated 'fixed' gear ratios. Thus it drives more like a normal automatic.
(Personally wish I could switch to the normal CVT function though.)
The Insight on the other hand has it's CVT locked to normal drive mode so paddle shifts are not possible despite the driver animation of readying for a shift at high RPM.
- Most Audis are specified with a front LSD but no rear one. Perhaps this gives the feeling that power is being shuffled to the rears as the fronts are less likely to wheelspin freely.
- Part of the reason the R8 5.2 V10 grips so well is that it was given meaningful racecar-lite front downforce. (Around the value of the Viper ACR if I remember right.) Other supercars like the Gallardo and the SLR were given zero front downforce.
Funnily enough, I read some independent-wind-tunnel-test-forum-thing a long while back stating that the actual R8 V10 would suffer more from high speed front-end lift while the LP560-4 would encounter the opposite, rear-end lift at high speed. (200 kph. And for more trivia, a stock C6 ZR1 suffered both front and rear lift at that speed.)
- Despite the existence of the Golf GTi/R and the Scirocco R, the Audi TTS still sounds like the 3.2 V6. Thus I could argue that this is a even bigger 'wrong sound' culprit than the Lamborghini V12s as the correct sound is present elsewhere in the game (!).
- GT5 generally does well with raising spoiler effects (like the Aventador example above). However, there are also 2 screw-ups among premium cars.
The Gallardo's doesn't raise at all while the MP4-12C should have a very mild tilt in certain conditions, though it works correctly as an air-brake. McLaren says that it would tilt in wet conditions, during high speed cornering and if the driver 'requests' it with the interior button.
- On the topic of nit-picking, the older '07 GT-R is the only 'ordinary' R35 GT-R where PD bothered to take into account the slightly different look/design of front versus rear wheels.
- The Leaf appears to be the only electric powered car where the dash displays work. (Including hybrids.)
