Porsche 959 is a sports activities automobile synthetic through Porsche from 1986 to 1989, first as a Group B rally automobile and later as a criminal manufacturing automobile designed to fulfill FIA homologation guidelines requiring that a minimal range of two hundred road criminal gadgets be constructed.

In 1986, it held the identify because the world's quickest road-criminal manufacturing automobile. During its manufacturing run, it became hailed because the maximum technologically superior street-going sports activities automobile ever constructed and the forerunner of all destiny high-quality vehicles. It became one of the first excessive-overall performance motors to apply an all-wheel pressure gadget, imparting the premise for Porsche's first all-wheel pressure Carrera four model. In fact, it satisfied Porsche executives of the gadget's viability so nicely that they selected to make all-wheel pressure widespread on all variations of the 911 Turbo beginning with the 993 version. In 2004, Sports Car International named the 959 primary on its listing of Top Sports Cars of the Nineteen Eighties.

Development of the Porsche 959 (at the start known as the Gruppe B) commenced in 1981, rapidly after the enterprise's then-new Managing Director, Peter Schutz, took his office. Porsche's head engineer on the time, Helmuth Bott, approached Schutz with a few thoughts approximately the Porsche 911, or extra aptly, a brand new one. Bott knew that the enterprise wanted a sports activities automobile that they might hold to depend on for years yet to come and that might be advanced as time went on. Curious as to how a lot they might do with the rear-engined 911, Bott satisfied Schutz that improvement exams must take place, or even proposed studying a brand new all wheel pressure gadget. 

Schutz agreed, and gave the challenge the inexperienced light. Bott additionally knew thru enjoy that a racing software commonly helped to boost up the improvement of recent models. Seeing Group B rally racing as the appropriate area to check the brand new mule and its all wheel pressure gadget, Bott once more went to Schutz and were given the pass beforehand to increase a automobile, primarily based totally on his improvement mule, for opposition in Group B.Porsche advanced an already current engine in preference to developing a brand new one from scratch. 

The powerplant, a dual-turbocharged six-cylinder boxer engine with an air-cooled block and water-cooled heads, displaced 2.eighty five liters, approximately 1/2 of a liter much less than a cutting-edge 911 engine. It became coupled to a completely unique guide gearbox supplying five ahead speeds plus a "G" off-street gear, in addition to reverse. The motor had at the start been advanced for the "Moby Dick" race automobile after which been redeveloped barely for the short-lived Porsche Indy Car and numerous different tasks earlier than being "tweaked" a closing time to be used withinside the 961, the 959's racing counterpart. 

The water-cooled cylinder heads mixed with the air-cooled block, four-valve heads and sequential turbochargers allowed Porsche to extract 331 kW (444 hp) from the compact, green and rugged strength unit. The use of sequential dual turbochargers instead of the extra ordinary same turbochargers for every of the 2 cylinder banks allowed for clean seamless shipping of strength throughout the engine RPM band, in comparison to the abrupt on-off strength function that outstanding Porsche's different turbocharged engines of the period. The engine became used, truly unchanged, withinside the Porsche 959 street automobile as nicely.

In an try to create a rugged, light-weight shell, Porsche followed an aluminium and Aramid (Kevlar) composite for frame use at the side of a Nomex floor, in preference to the metal commonly used on their manufacturing vehicles. The vehicle's weight of three,a hundred ninety pounds (1,450 kg) helped to acquire its excessive overall performance level.

Porsche additionally advanced the auto's aerodynamics, which have been designed to boom stability, as became the automated ride-top adjustment that have become to be had on the road automobile (961 race vehicles had constant suspensions). Its "0 lift" aerodynamics have been a huge a part of maintaining it drivable. Porsche 959 additionally featured Porsche-Steuer Kupplung (PSK) which became on the time the maximum superior all-wheel-pressure gadget in a manufacturing automobile. Capable of dynamically converting the torque distribution among the rear and the front wheels in each everyday and slip conditions, the PSK gadget gave the 959 the adaptability it wanted each as a race automobile and as a "high-quality" road automobile. Under difficult acceleration, PSK may want to ship as a lot as 80% of to be had strength to the rear wheels, supporting make the maximum of the rear-traction bias that happens at such times. It may also range the strength bias relying on street floor and grip changes, supporting hold traction in any respect times. 

The dashboard featured gauges showing the quantity of rear differential slip in addition to transmitted strength to the the front axle. The magnesium alloy wheels have been unique, being hole inner to shape a sealed chamber contiguous with the tire and prepared with a integrated tire stress tracking gadget.

The 1983 Frankfurt Motor Show became selected for the disclosing of the Porsche Group B prototype. Even withinside the final hours of October nine, completing touches have been being implemented to the auto to head on show the following morning.

First client deliveries of the 959 road version started out in 1987, and the auto debuted at a value of $225,000 USD according to unit, nevertheless much less than 1/2 of what it value Porsche to construct every one. Production led to 1988. In total, 337 vehicles have been constructed, along with 37 prototypes and preproduction models. At least one 959 and one 961 continue to be withinside the Porsche anciental corridor in Stuttgart, Germany.

In 1992/1993, Porsche constructed 8 959s assembled from spare components from the stock at the producing webweb page in Zuffenhausen. All 8 have been "Komfort"-variations: 4 in purple and 4 in silver. These vehicles have been a lot extra expensive (DM 747,500) than the sooner ones (DM 420,000). The later vehicles additionally featured a newly advanced speed-touchy damper gadget. The vehicles have been offered to chose creditors after being pushed through works employees for a while and are nowadays through a ways the maximum sought-after 959s.

Porsche 959 became now no longer road criminal withinside the United States previous to 1999 whilst the "Show and Display" regulation became passed, even though an unknown range have been imported through the "gray market" at some stage in the overdue Nineteen Eighties as display pieces. During the model's improvement Porsche refused to offer the US Department of Transportation with the 4 959s they required for crash trying out, and the auto became in no way licensed through the National Highway Traffic Safety Administration for road use withinside the U.S. With the passage of "Show and Display" the crash check necessities have been eliminated and importation of the 959 became allowed, assuming the auto may want to meet the emissions requirements relevant in 1987.
