1992 Ferrari 512 TR news, pictures, and information

In 1991 the Testarossa evolved into the 512 TR wîth subtle exterior changes to improve aerodynamics. The alterations included a one-piece nose wîth rounded front grille, flush mounted lights and ducts, and a new undertray. At the rear a small kamm tail smoothed airflow. High speed stability and cooling improved, while lift was reduced.

Structure

The 512 TR had a floor pan strengthened at high stress points by chromium-molybdenum steel. New welding techniques strengthened joints. The drivetrain and rear suspension of the 512 TR were directly mounted on the full rear frame. These changes contributed to substantially increased torsional rigidity and decreased weight.

Drivetrain

The engine of the 512 TR evolved significantly to produce 421bhp at 6750rpm, and 360lbs-ft of torque at 5500rpm. The torque curve of the 512 TR is somewhat more progressive than that of its predecessor. These improvements were achieved through numerous small changes including a strengthened block, a 10:1 compression ratio, revised valves, and a new intake system that ingeniously changed the intake of air. A Bosch Motronic 2.7 system controlled the engine.

Wheels

To fully exploit its power, the 512 TR was also given new cast alloy wheels. These wheels are thinner spoked versions of the Testarossa's, for improved brake cooling. The five hub bolts remain. These wheels are18'X8' wîth 235/ZR40 tires at front, and 18'X10.5' wîth 295/ZR35 tires at the rear.

Interior

The interior of the 512 TR differed most obviously from the Testarossa by changes to the center console, providing a more spacious feeling in the cabin. The basic shape and arrangement of the dashboard was unchanged, though its edges were rounded. Some gauges and instruments were relocated within the binnacle. The 512 TR was also given an updated Momo §teering wheel wîth a slightly thicker leather covered rim. The seats were redesigned and lowered.
