Ferrari 512TR & 512M
An evolution of the Testarossa, the 512TR was released in 1992. Both the design and the mechanicals were revised to keep the car ahead of the competition.
The design featured, most visibly, a new 348-style nose, whilst revisions were made to the rear lights and slatted grille, the engine cover and various other areas. New (still 5-spoke) 18 inch wheels were fitted with narrower tyres at the front (235/40) and wider at the rear (295/35). The intrior also received many small changes.
The engine retained its 4943cc capacity, 48 valves and red cam covers, but gained over 30bhp thanks to larger valves, a higher compression ratio (10:1) a new engine management system and new inlet and exhaust systems. It was also located lower in the chassis (still over the gearbox) due to the new exhaust system. The suspension remained effectively the same, with double wishbones all round and twin coil/damper units at the rear, although the front track was increased whilst the rear decreased.
Performance, predictably, improved, with 0-100km/h in 4.8 seconds and a top speed of 314km/h (192mph).
In 1994 the 512M took over in production. This featured further significant external modifications including new, fixed headlights (replacing the pop-up lights in the Testarossa and 512TR) and new round rear lights, not covered by the black slats. The weight of the car was further reduced by around 18kg whilst the engine power went up by 12bhp.
