The 3000GT VR-4, however, is four-wheel drive. And it needs all the traction it can get: A twin-turbocharged, twin-intercooled V6 with dual overhead camshafts and four valves per cylinder spins out 320 horsepower at 6000 rpm. Even more impressive is that it produces 315 foot-pounds of torque at just 2500 rpm. All VR-4s come with a German-designed and North Carolina-built Getrag 6-speed manual gearbox.
MacPherson struts up front employ negative offset steering geometry for better braking stability. The VR-4's rear suspension is a double wishbone arrangement.
The VR-4 also has 4-wheel steering. Toe-control links in the rear suspension induce toe-in for greater stability when cornering and under hard braking and acceleration. It does this by adjusting the toe, or alignment, up to 1.5 degrees, steering the rear wheels in the same direction as the front wheels. (This only occurs at 31 mph or faster.)
Big four-wheel vented disc brakes slow the VR-4 down. ABS is standard.
The four-wheel-drive system consists of a center differential with a limited-slip viscous coupling; the rear differential also uses a viscous coupling. The normal torque split front/rear is 45/55 respectively so that the VR-4 has rear-drive bias under normal conditions. If slip occurs, torque is sent to the tires with greater traction. Next Page
