The Porsche 944 is a sports car built by the German manufacturer Porsche from 1982 to 1991. It was conceived as a replacement to the Porsche 924, being the new base model of the entry of the mark, although 924 production continued through 1988. The 944 was intended to stay the sale until well into the 1990s but major revisions planned for the 944 S2 were finally embodied in the new model 968, his successor. Although it was built with the base of the chassis of the 924 and the 944 offering the latest in technology in the 1990s. It was a model of success that were developed in versions coupé and cabriolet with gasoline engines from 2.5 L To 2.7 L and 3L versions 8 valves, 16 V and Turbo.

History and overview of models

The Porsche 924 was originally a joint project of VW-Porsche to develop a new model of Volkswagen or Audi. The joint venture VW-Porsche, which was formed with the intention of selling the 914, I had planned that this model would not have the good acceptance that has had the 356. However, the rate of sales was enough to not be ignored by VW so it was agreed that Porsche would develop a new model to be marketed as a VW or Audi. In 1972, the substitute for the version of Volkswagen of the 914, code EA-425 began development.
This model should use as many VW parts as possible but with the appearance similar to the Porsche 928 as the car was going to be sold probably as an Audi according to the agreement of marketing of Volkswagen-Audi-Porsche. Although testing had already begun in the spring of 1974 Volkswagen decided to cancel the program due to the costs of production, as well as the feeling that would be in direct competition with the recently released Volkswagen Scirocco that filled the hollow as cupe and sporty enough. The project almost disappears when the joint venture broke up and, due to the oil crisis of 1973-1974, VW withdrew the car definitely of all of the future plans of the company.

At Porsche, however, were convinced of its potential success and the dealers of the brand they wanted desperately a model "economic" that provides a large volume of sales. So it was that Porsche bought the project for more than $ 40 million in 1975 and finished its development, resulting in the model 924. For your manufacturing signed a contract with VW to build the plant to NSU in Neckasulm under the quality standards of Porsche.
The mechanical arrangement of the car you gave a great stability and excellent driving control in extreme situations, what we did receive many positive reviews. Even so its origins VW and the rough engine Audi 2L bit powerful of the early versions earned many negative reviews. Porsche introduced a 924 Turbo to increase performance and to counter these criticisms, but the price was considered too high by the time they were descending sales.

Rather than discard the model completely, the factory decided to develop the 924, as they had done with generations of the 911; Although the number would change, the 924 provided the basis for its replacement.
Thus was born the new 944 in the Porsche redesigned the chassis and left the engine Audi. In its place was installed a new engine 4-cylinder with 100mm diameter, 78,9 mm stroke and 2.5 L which block of aluminum came from a cylinder bank of the V8 5000cc of the 928 though in reality, very few parts are actually interchangeable.

It is not a natural choice for a luxury sports car a 4-cylinder in-line but the decision was that it was not practical to develop a new 6-cylinder engine in V or one of 6 on-line, in addition, would not fit in the engine bay. To eliminate the forces of middle and high vibrations that you get in a 4 cylinder so great was provided with a balancing system for 2-axis rotating spinning at double-speed the engine. This system was developed and patented in 1975 by Mitsubishi Motors, the axes of balanced wear a cams (weights) eccentric to produce the inertial forces necessary to balance forces secondary destabilizing, making a 4-cylinder engine as smooth as one of 6 online.

In the design we chose for the layout of the 924 carrera GT circuit with its expansion of bodywork to the wheels and improvements in the suspension and brakes. It is hoped that this new model with 163 HP, more masculine and 215 Km/h of top speed, was considered entirely Porsche and left to suffer from the criticism that plagued the 924 for its initial source Audi-VW.

Porsche introduced the 944 in 1982. It was faster than the 924 (despite having a slightly worse aerodynamics), was better equipped and more refined than the 924, it handled better, braked better every time and it also was more comfortable driving and, according to the factory said, reaching 0 to 100 Km/h in 8,4 sec. The car had a weight distribution almost perfect (50,7% of the. / 49.3% after.) thanks to the system "tranxale" with the engine in front and gearbox in the rear axle. This, together with the axis "weisachs" gave him a dynamic equilibrium and optimal behavior in curves the limit of adhesion excellent. The front suspension consisted of an independent system with shock-absorbers, MacPherson-type with coil springs, lower trapezius, and anti-roll bar. The rear consisted of a system of parallelograms deformable, torsion bars cross-cutting, anti-roll and dampers.

In the 2nd half of 1985 the 944 received its first significant changes. a new dashboard and new door panels, radio antenna integrated in windshield, upgrade the alternator (from 90 To 115 (A), the capacity of the oil pan is increased, new suspension arms, cushioning front and rear aluminum, larger fuel tank, electric seats and/or heated in option, sound system of high fidelity Porsche and revisions in the mounting of the "tranxale" to reduce the vibration and noise. The wheel of style "Cookie Cutter" used in the early 944 were updated to the new style "dialphone" (telephone dialer). The wheels Fuchs remain as an option. The cars of model year 1985 that already incorporated these changes are sometimes referred to as "1985/2".

944 S

In 1986, it appears the version 944S with a 2.7 L 16 V and 190 HP, and in the year 1987, it was again updated by joining ABS and airbags to increase the safety. Due to the ABS the track width was changed, and tires Fuchs were not available as an option.

944 S2

In 1989 appears the version 944S2, which was a version of the 944S of 16V, with the body design of the turbo and its capacity increased up to 3L. The power was 211 HP and the maximum torque is improved to 28.6 Kg.m. It incorporated changes in the injection, the brakes of the turbo, 250 HP, stabilizer bars stiffer and new alloy wheels of 16”. Thanks to all of this amounted to 100 Km/h in a second less that the 2.7 L 8-valve and around 240 Km/h of speed. Did not match the excellent performance of the turbo but it was driving more pleasant, smooth and linear so that (along with the $ 16,000 difference) opted to many of the buyers. The version cabriolet appeared soon after leaving the coupe.

In 1986 Porsche introduced the 944 Turbo, known internally as the 951 (952 for the driving units on the right). This had a turbo and intercooler in the initial version standard offered 220CV to 6000 rpm, and its price at the end of 1985 was around us $ 60,000. This he did to be placed on the same step of prices of the 911 and slowed down their potential success in spite of having a better behavior and performance are gross similar to the 911 Carrera 3.2 liter.

The Turbo also brought other important changes such as improved aerodynamics, a gearbox, reinforced with a system of oil cooling, and a final gear ratio different, a new radiator of cooling of engine oil (the maximum power used in a heat exchanger water-to-oil), wheels 16” series (on option tires Fuchs forged) and a firmer suspension to handle the extra weight. We reviewed all the internal components of the engine 951 (made more than 30 changes) to make sure that would endure increased heat and higher pressures and internal charges that would have to endure.

It introduced few changes in 1987. One of them was the elimination of the system of cooling of oil of the gearbox and changes to the suspension arms of the suspension. It is also offered, for the first time in a production car, the dual airbags as standard. The engine remained the same M44/51 the model of 1986.
