Group A R32 GTR Key Specs:
4 wheel drive
Rear diff speed
4 wheel speed sensors control the 4wd system
ETS pump varies oil pressure to transfer case to distribute force between axles
The R32 GTR’s 4 wheel drive system allowed the car to operate as 2 wheel drive only in fast corners and 4 wheel drive when the system detected slip at the rear wheels. When you can do this with your transmission you are going to be in a good place lap time wise.
The Nissan Skyline R32 GTR had around 100 bhp more than the Sierra Cosworth‘s and the GTR’s 4 wheel drive system was key to getting this power to the ground in the dry and especially the wet.
