Model development
After a production period of the Porsche 911 over 15 years, a model change was urgently needed. Porsche was the end of the 1980s in a serious crisis. The Porsche 944, the Porsche scored his biggest sales, could not sell more with the hoped-for numbers.
Also be converted the customers who wanted a Porsche 911 drive. It stood in the buying decision is no longer the pure driving performance of the car in the foreground, but also the driving comfort. The construction of the 911 based in its basic features still at the level of the 1960s and was no longer appropriate in many parts. Although the 911 was always continued to improve, yet the end of the commercially sensible possibilities was reached.
In order to offer a modern and marketable vehicle back, the Porsche 964 was developed. In developing this model, Porsche 959 to draw on a wealth of know -how thanks to earlier prototypes and small series models such as the legendary Porsche.
Therefore, the 964 includes many new features that did not exist in the classic Porsche 911: the first time was at Porsche with the 964 offered a mass-produced car with all-wheel drive. The new concept was a simplified version of the 959 - wheel-drive technology.
Furthermore, Porsche rejected the torsion bar suspension used for 40 years of the types 356 and 911: The 964 has a completely new aluminum chassis with MacPherson struts at the front and rear coil springs. Power steering and ABS were standard; the new 3.6 -liter engine was a twin-spark ignition with knock control and a fully controlled three- way catalytic converter.
Despite the many changes, the sales name Porsche 911 was still maintained; the term 911 was too strongly associated at this time with Porsche, as that would have been it can do without. In addition, the Porsche 964 corresponded with its features exactly what the 911 customers expected of a modern sports car the end of the 1980s.
Marketing with a designed by the agency Jung von Matt catchy advertising was supported: " You can have breakfast any longer. They are used to back for dinner. Is there a better family car? " The Porsche 964 was very successful and is now very popular on the used car market.
Body
The sold from 1988 Porsche 964 is the first major revision of the 911 body style since the beginning in 1973 built " G " model.
The G model has been revised in many ways, the superficial biggest changes are noted on the bumpers. The new bumpers were compared with those of the previous model have been greater and were hotly debated among Porsche fans.
By aerodynamically favorable body shape and especially because of the full panel of the car floor a hitherto unparalleled low air resistance at 911 with a drag coefficient of 0.32 was achieved. To achieve a 964 with 250 hp, the same terminal velocity of about 260 km / h as the 37 kW ( 50 PS) more powerful Porsche 911 Turbo ( Type 930) from the old G- series. The automatically extending at a speed of about 80 km / h rear spoiler of the 964 replaced the previously optional fixed rear spoiler for all Carrera models. This causes in addition to the better aerodynamics and improved engine cooling.
First, the car was only offered in the all-wheel version of the Carrera 4 and offered in parallel with the model 911 Carrera 3.2 the old form. From 1989 ( model year 1990/L-Programm ) of the Porsche 964 was also available with rear-wheel drive as the Carrera 2. Both models were sold in the Body: Coupé, Cabriolet and Targa.
The top model 911 Turbo based on the 964 came in 1991 model year (M ) program on the market. In this model, many features of the old turbo model ( Porsche 930) were, such as the wide fenders over the front and back and fixed large rear spoiler. When driving the proven engine type 930 of the previous model has been used, its performance with an improved engine control and a 30% larger intercooler to 235 kW ( 320 hp) has increased.
In 1993 ( model year 94/R-Programm ), the Speedster was built as a separate model of the 964 series in a small series of only 930 pieces. As a basis for the Speedster the 964 Carrera 2 Cabriolet served with a shortened windscreen and revised roof construction. Particularly striking is the rear view with the two " humps". In addition, about 15 Speedster have been built in the Turbo look with wide body to customer in the Porsche Exclusive department.
Engine / Transmission
Even when 964 was still set to the proven air-cooled six-cylinder boxer engine with dry sump lubrication, with dual ignition and an improved electronic engine control DME ( Digital Motor Electronics ) was further developed by Bosch.
The 400 cc enlarged to 3.6 -liter displacement engine delivers at a speed of 6100 rpm, a power output of 184 kW (250 hp). Another innovation was the DME with integrated knock control (left and right respectively, a knock sensor, the rows of cylinders 1-3 and 4-6 are connected to an aluminum bridge ), which automatically performs a spark at different fuel qualities. Together with the aerodynamically enhanced body could thus fuel consumption compared to the old 3.2-liter engine can be lowered. The tank was thus reduced from 85 liters of the previous model to now 77 liters, the luggage compartment size zugutekam.
After produced from 1968 to 1980 semi-automatic " Sportomatic " an automatic transmission in the 911 was from January 1990 964 Carrera 2 with the " Tiptronic " available again. The Tiptronic allows the driver next to the fully automatic gear selection the opportunity to choose the four gears manually. The Tiptronic development was based on that used in the Porsche 962 Porsche double - clutch ( PDK) of racing.
From model year 1991, there were in addition in addition to the Carrera and Speedster models with 184 kW ( 250 hp), the new top model 911 turbo with turbocharger and intercooler. Its engine had at first like the Porsche 930 had a displacement of 3.3 liters and made 235 kW (320 hp). As of January 1993, the new engine type M64 was used with a larger displacement of 3.6 liters, also for the " Turbo", which reached the same turbocharger and intercooler as its predecessor, now a power output of 265 kW (360 hp). The 3.6 liter turbo model has a standard 92 -liter fuel tank. At 964 turbo 993 turbo was dispensed with dual ignition otherwise used, as well as the successor.
All models are equipped with a fully controlled three - way catalytic converter.
