Using the Madness engine (developed by Slightly Mad Studios (Project CARS 2)), Reiza Studios has improved their car audio by increasing tick rates compared to the Automobilista 1 audio engine. This results in a higher fidelity audio in-game and a noticeably smoother audio curve as seen in the new vs old comparison below.

Reiza Studios has shared a work in progress video highlighting audio improvements made to three high-revving cars seen in the video below.
Regards to physics, as both physics and controller tick rates were already high, it left less room for improvement. Still, a small bump has been made which should allow for greater control. To demonstrate the higher tick rate, Reiza has released another work in progress video showing a very high-powered car on slick tyres in wet conditions below.
The drivetrain model has also seen improvements specifically for cars with manual transmission (Reiza assures us that players can´t get away abusing their gearbox speed shifting or skipping gears without clutching or rev-matching).
The new drivetrain model will eventually include damage to gears and gearbox from recurring miss-shifts. You can see the new drivetrain model in action in the work in progress video below.
