The original Testarossa was thoroughly re-engineered for 1991 and released as the 512 TR, effectively a completely new car. It increased the output of the 4.9 L engine to 428 PS (314.8 kW/422.1 hp).

The 512 TR's engine was modified in many ways. Nikasil liners were added, along with a new air intake system, Bosch engine management system, 10.1:1 compression ratio with new pistons, larger intake valves, and a revised exhaust system. In addition to the higher peak power, the modifications delivered a more broad power curve for better acceleration.

Gearshifting effort, long a complaint about the Testarossa, was eased with a new single-plate clutch, sliding ball bearings, and better angle for the shifter. The braking system included larger front rotors and cross-drilling all around. Quicker steering, lower-profile tires, and new shock settings improved handling. Most importantly, engine and gearbox position was rethought, which improved the centre of gravity, aiding the handling and making the car less fearsome on the limit.

The interior was revised too, with the center console split from the dashboard, and the climate controls relocated. Pininfarina tweaked the body of the car to better integrate the spoilers and engine cover and update the design in line with the recently released 348. A recall was issued in 1995, regarding fuel hose fitting issues. Over 400 models had this defect. Certain variances in temperature and environment would cause the hose to fail.

The 512 TR could accelerate to 100 km/h (62 mph) in 4.8 seconds and could reach the quarter mile mark in 12.8 seconds. Top speed was 192 mph (309 km/h). It cost US$212,160 in 1992 with luxury items, the "gas-guzzler" taxes, and destination freight.
