Power Plant:
3.8 liter SC underhood view   The Super Coupe's comes equipped with a 3.8 liter V-6 powerplant that is force-fed with an Eaton Corporation supercharger. The 8.2 to 1 compression ratio, combined with six computer controlled  sequentially fuel injectors, completes the well rounded underhood package. While running at a maximum 15,600 rpm's, the supercharger provides 12 psi of boost and as a resultant it develops 210 bhp at 4000 engine rpm's. The engine develops 315 lb-ft of torque at 2600 rpm. The supercharged V-6 delivers ample power without much noise but an underdrive kit and a performance chip are available to boost the horsepower rating to 255 bhp.

Transmission:
  The 4-speed automatic transmission features a 0.67:1 overdrive ratio and an electromechanical lockup to eliminate torque-converter slippage on the supercharged models.

Braking System:
  The Thunderbird SC braking system features 4 wheel disc brakes with ABS. The Thunderbird SC can stop in 140 ft from 60 mph. From a speed of 80 mph, it takes the SC 247 ft. to come to a safe stop.

Suspension System:
  Up front, the T-Bird rides on a short and long-arm system rather than a more conventional MacPherson-strut arrangement. This system features variable-rate coil springs, a 1.2 in. diameter anti-sway bar and electronically controlled nitrogen-pressurized gas shocks.

  The rear suspension is even less conventional for a rear wheel drive domestic sedan. It's fully independent with a large lower H-arm on which the variable-rate coil spring rides and there is a smaller U channel upper arm. These arms are tied together by a cast aluminum knuckle. In addition, there is a 1.1 inch diameter anti-roll bar and gas-pressurized shocks with electronically controlled damping. The car's gripping power comes from the big P225/60R-16 Goodyear Eagle GT-II's mounted on 7 inch wide light alloy wheels.

  The SC is equipped with an electronic suspension control. You can definitely feel a difference in the ride when you switch from the soft and sport (Firm) setting. The ride control system is made by Tokico. A computer monitors vehicle speed, brake-line pressure, steering angle and engine-computer acceleration signals to determine the shock valving. There are two switch settings. These settings are: Auto and Firm. The automatic setting selects soft shock valving for a smooth, comfortable ride. When driving conditions require a firm ride, it automatically overrides the soft valving. The firm position is simply an override that selects the firm setting in all driving modes.
