The Porsche 911, internally type 993, is the fourth generation of the 911 model of Porsche sports car, manufactured and sold between January 1994 and early 1998 (model years 1995–1998 in the United States), replacing the 911, type 964.
Porsche 911 , introduced in 1989, was the first to be offered with Porsche's Tiptronic transmission and four-wheel drive. In 1990, Porsche drew up a memorandum of understanding with Toyota to learn and benefit from Japanese lean manufacturing methods. In 2004 it was reported that Toyota was assisting Porsche with hybrid technology. [23]
The original Porsche 901 on display at the 2019 Geneva Motor Show. The 911 traces its roots to sketches drawn by Ferdinand "Butzi" Porsche in 1959.

The VarioCam timing system was first introduced on the 968 and would later become a feature of the Type 993 air ...
In April 2011, Porsche announced the third generation of the 997 GT3 RS with an enlarged 4.0-litre engine having a power output of 500 PS (368 kW; 493 hp).

The development work from the Turbo S LM-GT helped Porsche in creating the 993-generation 911 GT2 in 1995, which would be mass-produced and sold to racing customers. Some teams, unable to buy new 911 GT2s, developed their own twin-turbo racing versions of the 964 Turbo to mimic the Turbo S LM-GT, but lacked the success of the factory project.
Porsche decided to restart production to reproduce the lost cars. [18] In late September 2017, the 911 GT2 RS driven by Porsche test driver Lars Kern set a 6:47.3 minute lap time around the Nürburgring Nordschleife, averaging a speed of 184.11 km/h (114.40 mph). This made it the fastest production car lap time recorded on the track at the time.
However, its frontal chassis is based on the 993-generation 911, while the rear subframe was derived from the 962C Group C prototype [5] along with its water-cooled, twin-turbocharged and intercooled, 4 valves per cylinder 3,164 cc (3.2 L) flat-six engine fuel fed by Bosch Motronic 5.2 fuel injection, which was longitudinally-mounted in a rear ...
