The powerplant, a twin-turbocharged boxer six-cylinder engine with an air-cooled block and water-cooled heads, displaced 2.85 liters, about half a liter less than a contemporary 911 engine. The motor had originally been developed for the “Moby Dick” race car and then been redeveloped slightly for the short-lived Porsche Indy Car and several other projects before being “tweaked” a last time for use in the 961, the 959’s racing counterpart.

it was one of the first high-performance vehicles to use an all-wheel drive system; it provided the basis for Porsche’s first all-wheel drive Carrera 4 model; and it convinced Porsche executives of the system’s viability so well that they chose to make all-wheel drive standard on all versions of the 911 Turbo starting with the 993 variant. During its lifetime, the vehicle had only one other street legal peer with comparable performance, the Ferrari F40.[citation needed] The 959’s short production run and performance have kept values high.[citation needed] In 2004, Sports Car International named this car number one on the list of Top Sports Cars of the 1980s.

In addition to the numerous mechanical upgrades, the new model also received significantly evolved styling both inside and out, with a more modern, streamlined look and more standard luxury than on the 944. Production was moved from the Audi plant in Neckarsulm (where the 924 and 944 had been manufactured under contract to Porsche), to Porsche’s own factory in Zuffenhausen.

Porsche’s 944 model debuted for the 1982 model year, was updated as “944S” in 1986 and as “944S2″ in 1989. Shortly after the start of production of the S2 variant, Porsche engineers began working on another set of significant upgrades for the model, as executives were planning a final “S3″ variant of the 944.

Changes to the 968’s powertrain also included the addition of Porsche’s then-new VarioCam variable valve timing system, newly-optimized induction and exhaust systems, a dual-mass flywheel, and updated engine management electronics among other more minor revisions. The 968’s engine was the second-largest 4-cylinder ever offered in a production car up to that time. A new 6-speed manual transmission replaced the 944’s old 5-speed, and Porsche’s dual-mode Tiptronic automatic became an available option. Both the Variocam timing system and Tiptronic transmission were very recent developments for Porsche. The Tiptronic transmission had debuted for the first time ever only 3 years prior to the debut of the 968, on the 1989 Type 964 911. The Variocam timing system was first introduced on the 968 and would later become a feature of the Type 993 air cooled six cylinder engine.

Shortly after the start of production of the S2 variant, Porsche engineers began working on another set of significant upgrades for the model, as executives were planning a final “S3″ variant of the 944. During the development phase, 80% of the 944’s mechanical components were either significantly modified or completely replaced by the engineers, leaving so little of the outgoing S2 behind that Porsche management chose to introduce the variant as a new model, titling it 968.

It took over the entry-level position in Porsche’s lineup from the 944, with which it shared about 20% of its parts. Ultimately, the 968 became the final model in an evolving line started almost 20 years earlier with the introduction of the 924.Porsche’s 944 model debuted for the 1982 model year, was updated as “944S” in 1986 and as “944S2″ in 1989.

Nordschleife circuit in the Eifel Mountains has been achieved during the qualifying session for the 1983 1000 km Nürburgring, by Stefan Bellof, who drove his 956 around in 6 minutes 11.13 seconds, at an amazing average speed (considering the difficulty of the track layout) of 202 km/h (126 mph). The race lap record is held by the same Bellof, during the 1983 1000 km Nürburgring, the lap being clocked at 6:25.91.

At the 1985 1000 km of Spa, Bellof died after colliding with Jacky Ickx’s newer 962. Safety concerns over the 956 led to the eventual end as teams upgraded to the safer 962.

World Championship for Makes with Jacky Ickx and Derek Bell driving for the factory. After missing the following round at the 1000 km Nürburgring for developmental reasons, the Ickx/Bell unit reappeared at the 24 Hours of Le Mans. They led the race for the entire 24 hours, eventually taking the overall win - their third win together. As they had already won in 1981 with a Porsche 936 that had used an early version of the 956 engine, their car had start number 1. The two other factory 956 followed them, so the three factory Porsches finished 1-2-3 in the order of their starting numbers.

Boosted by this success, Porsche sold customer versions of the 956 to privateer teams such as Joest Racing, Obermaier Racing, John Fitzpatrick Racing, Richard Lloyd Racing, Kremer Racing and Brun Motorsport who raced them independently of the factory.
