Ferrari 512 TR

After a long production run of over 7000 cars, Ferrari updated their Testarossa design into the 512 TR. The body was slightly updated by Pininfarina, while much work was done by Ferrari under the hood to gain roughly 40 more bhp.

The 512 TR sports a 4.9-litre (4.943 L (4,943 cc)) longitudinally rear-mounted flat-12 engine.[25] Each cylinder of the engine has four valves, with forty-eight valves total. The engine is lubricated via a dry sump system, and has a compression ratio of 10.00:1.[27][29] These combine to provide a maximum of 491 N⋅m (362 lb⋅ft) at 5,500 rpm and a maximum power output of 315 kW (428 PS; 422 hp) at 6,750 rpm.[25][27][29]

The car can accelerate from 0–100 km/h (62 mph) in 4.8 seconds[26] and on to 161 km/h (100 mph) in 10.7 seconds. It can complete a standing (from stationary) quarter mile in 13.2 seconds or a standing kilometre in 23.4 seconds. The 512 TR has a top speed of 313.8 km/h (195.0 mph).

A recall was issued in 1995, regarding fuel hose fitting issues.[30] Over 400 cars had this defect which was caused by variances in temperature and environment. Another recall was issued in relation to the passive restraint system on seat belts not functioning properly, on over 2,000 cars.[30] If the restraint system suffered a mechanical or electrical failure only the lap belt would provide safety to the occupant.

The 512 TR’s engine was extensively reworked. Nikasil liners were added, along with a new air intake system, Bosch engine management system, larger intake valves, and a revised exhaust system. In addition to the higher peak power, the modifications delivered a more broad power band for better acceleration.

Gearshifting effort, a prolonged complaint about the Testarossa, was eased with a new single-plate clutch, sliding ball bearings, and better angle for the gearshift knob. The braking system included larger cross-drilled front rotors. Quicker steering, lower-profile tyres, 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 easier to drive.

The interior also received updates, with the centre console split from the dashboard, and the climate controls relocated. Pietro Camardella[31] at Pininfarina was tasked with redesigning the body of the car for better integration of the newly included spoilers and the new engine cover. The design was updated in line with the recently introduced 348.

The 512 TR has 18 in (457 mm) wheels with a width of 8 in (200 mm) at the front and 10.5 in (270 mm) at the rear. The tyre for the front wheels are 235/40 ZR 18 and 295/35 ZR 18 for the rear.[5][27][29] The front brakes have a diameter of 315 mm (12.40 in) and the rear brakes have a diameter of 310 mm (12.20 in).
