2WD vs 4WD drivetrain losses

[32godzilla]

I've been wondering lately if a 2WD car with exactly the same power and weight as a full time 4WD car would be quicker over the 1/4 mile without taking into account traction, wheelspin etc etc.

The reason I'm wondering this is why the GTR was built with a Torque split converter and not full time 4WD?? Is it to basically give grip for the initially takeoff then once wheelspin isn't a problem put all the power through the rear wheels to cut drivetrain loss?

its like that so it doesnt drive like a hyundi wrx

Hi 32godzilla, we typically see 50 kw losses through 2 wd Skyline and 65 kw losses in 4 wd.

The GTR 4wd drive system is set up such that it gives a rwd handling experience and only diverts drive to the front wheels when necessary. As fatz says "so it doesnt drive like a hyundi wrx".

Hope that helps
