Ferrari 512 TR, a sublime model, born from an evolution of the amazing Ferrari Testarossa

Improving the amazing lines presented by Pininfarina on the Ferrari Testarossa is not at all easy, yet they succeeded in Maranello: the Ferrari 512 TR has some aesthetic changes, thanks to which it is possible to improve the aerodynamics of the car.

Production of this new model officially began in 1991, seven years later than that of the Testarossa, and unlike the previous version, the 12-cylinder boxer was placed at a lower height from the ground. This modification, in addition to increasing the declared power of thirty-eight horses, also improves the handling of the vehicle, making the Ferrari 512 TR the worthy heir to the acclaimed Ferrari Testarossa.

The 512 TR takes the place of the Testarossa and is announced in 1992.

The name of the new model returns to indicate some of its technical characteristics: five refers to the capacity in liters of the engine, twelve to the number of cylinders and TR represents the abbreviation of Testarossa.

The main differences from an aesthetic point of view, compared to the previous version, consist in some changes made to the nose and tail of the car, in the air vent slits in the engine hood and in the design of the wheel rims.

Even the profile of the rear pillars, in a barely perceptible way, is modified: on the 512 TR they are linear, and join directly to the roof panel, thus abandoning the previous version of the Testarossa, consisting of a step and a perforated air grille vent.

Some changes are made to vary the interior design, such as the seats, the different profile of the steering wheel and some details of the finishes, while from the point of view of mechanics, many details of the engine and gearbox undergo some changes: the result obtained leads to an increase in overall power, and a more positive and rewarding use of the gearbox.

An important novelty, which cannot be noticed without a keen eye, concerns the engine and transmission, mounted 30 millimeters closer to the ground to lower the center of gravity, and thus improve the already high standards of road holding.

The bodies of the 512 TR are assembled, as well as on the Testarossa, on a chassis with a wheelbase of 2550 millimeters. The internal reference number is F 110 HB, and the construction criteria follow those already adopted for the previous model.

All chassis numbers will take the order of the continuous numbering, and various models, destined for world markets, will be made with the driver's seat placed both on the left and on the right.

The new aesthetic appearance of the nose bears a close resemblance to the 348 model, seen for the first time in 1989. The front grille is adorned with a chromed Prancing Horse, flanked by the front light clusters that incorporate the position lights in a single block. the direction indicators and fog lights.

In the back the panel is decorated with a style rich in curved lines, and changes the shape of the recessed seat, where the plate is placed. The bonnet of the Testarossa is equipped with a raised central panel in the same color as the bodywork, with satin black air vents on the sides and in the rear section.

On the 512 TR, the raised section and the air vents of the new profile are painted in satin black, while the portion of vents located in the rear area maintains the body color.

The 512 TR code embellishes the rear lip of the bonnet, while the Ferrari inscription is present in the upper part of the facade.

The Testarossa lettering characterizes the upper part of the raised central section, while the new alloy wheels are a very elegant interpretation of the classic Ferrari design in the shape of a five-pointed star, made with thinner spokes.

The rims, as in the Testarossa version, have different dimensions: the front ones measure 8J by 18 inches in diameter, while the rear ones measure 10.5J by 18 inches.

This involves a slight increase in the front track, with a consequent reduction, albeit minimal, of the rear one. The rims hide large perforated and ventilated disc brakes, equipped with calipers with four pistons. Their control circuits, separated for the front and rear train, are of the hydraulic type and can boast the help of the servo assistance.

The independent suspension and steering systems basically follow the similar concepts already seen on the Testarossa, from which they differ only in some small variations and adjustments made to adapt them to larger diameter wheels and to obtain a more precise and stable ride.

The twelve-cylinder boxer, with four valves per cylinder and dry sump lubrication fitted on the 512 TR, is an improved version of the already advanced power unit fitted to the Testarossa.

This maintains the same displacement of 4943 cm³, with bore and stroke of 82 by 78 millimeters, and have as internal reference number 113 G, but has modified inlet ducts, and larger valves, thus favoring an inlet more efficient than the air / petrol mixture.

In addition, fuel injection and electronic ignition are replaced with an integrated Bosch Motronic M2.7 system, which is able to offer higher performance than the previous version. The new pistons used increase the compression ratio from 9.3:1 to 10:1, and new profile camshafts are designed.

All these improvements report an increase in declared power of thirty-eight horsepower, which will reach values ​​of 428 hp at 6750 rpm on models destined for the European market, and 421 hp at the same rpm on models made for the United States.

The increase in power will also improve acceleration, increasing the maximum speed by about 20 km / h compared to the Testarossa, reaching a top speed of 314 km/h.

The 512 TR will be produced between 1991 and 1994, before being replaced by the F512 M. The units built amounted to 2.261 units, and the chassis are numbered from 89.100 to 99.743.
