The R33 GT-R launched in January 1995 with the base model GT-R and the V-spec model. The V-spec model weighed in 10 kg (22 lb) heavier, and had sportier suspension resulting in lower ground clearance. The V-spec also featured the newer ATTESA E-TS Pro all wheel drive system, which included an Active Limited Slip differential. The V-spec model also included a four wheel independent channel anti-lock braking system.
