Mitsubishi 3000GT VR4 Specifications:
The 91-93 models came stock with a twin-turbo charged, DOHC, 24 valve, 3.0-liter V6 that produces an
incredible 100hp/liter for a total of 300hp. The car has All-Wheel-Drive (AWD), All-Wheel-Steering (AWS),
an Electronically-Controlled-Suspension (ECS), an Active-Aero system, an Active-Exhaust system, an all
wheel Antilock-Brake-System (ABS), and numerous other options.
The AWD has a 45/55 rear torque bias with viscous coupling unit to spread the torque where it's needed. Once
you have an AWD vehicle, you'll never go back. There's nothing like cornering with AWD and feeling all four
wheels working you through the turn as you're locked to the road.
The AWS is a same-phase system that turns the rear wheels in the same direction as the front wheels (hence
same-phase) at speed. The rear wheels turn up to 1.5 degrees in-phase providing excellent yaw and
lateral acceleration response. When changing lanes at speed the car literally "shifts" over a lane,
rather than following the nose over.
The ECS allows the driver to instantly select from either "Tour" or "Sport" suspensions. These options
allow for a more comfortable ride when driving on rough city streets, or a more responsive, firm ride
when the situation calls for it. In addition, the system provides constant dynamic ride control by
stiffening the struts independantly, or in conjunction. By adjusting the the struts, the system minimizes
body roll during corning, squating during acceleration, and nose-dive during breaking.
The Active-Aero system on the VR4 provides a negative lift coefficient of up to -0.07 to greatly
improve high-speed stability. The car is literally sucked down to the road. This is accomplished
with two mechanisms. The first is the front air dam which lowers up to 2 inches, then retracts when
the car slows. The second is the rear spoiler which increases its attack angle by 14 degrees then
returns to horizontal as the car slows. The whole system deploys at speeds in excess of 50mph, then
retracts when the speed drops below 31mph.
The Active-Exhaust system allows the driver to instantly change the exhaust from "Tour" mode (i.e. quiet),
to "Sport" mode (i.e. loud). The idea behind the Tour/Sport difference is that the Sport mode flows
through a less restrictive muffler, and therefore is more free-flowing.
