In 2004, production of the Carrera GT commenced in Leipzig, and at EUR 450, 000 ($ 440, 000 in the United States ) it was the most expensive production model Porsche ever built.

Internally, Porsche called it 931 ( left hand drive ) and 932 ( right hand drive ), much like the 911 Carrera Turbo, which had been " Type 930 ".

After a successful sales run of both naturally aspirated and turbo models, in 1980 Porsche surprised everyone and release the 924 Carrera GT, making clear their intention to enter the 924 in competition.

By adding an intercooler, increasing compression to 8. 5: 1 as well as various other little changes, Porsche was able to develop the 924 Turbo into the race car they had wanted, dubbing it the 924 Carrera GT.

Lastly, in 1981 Porsche entered 1 of 2 specially built 924 Carrera GTP's ( Aka: 944GTP Le Mans ) which Porsche Motorsports introduced a new prototype highly modified 2. 5 liter I4 engine.

Unusual features were champagne gold metallic paint, matching brushed gold flat disc wheels, two-tone leather interior, a plaque containing the production number on the dash and the extremely collectible three-piece Porsche luggage set.

In order to help make the car more functional, as well as to distinguish it from the naturally aspirated version, Porsche added a NACA duct in the hood and air intakes in the badge panel in the nose, 15-inch spoke-style alloy wheels, four-wheel disc brakes with 5 stud hubs and a five-speed transmission.

The larger disc brakes made the Red Line capable of decelerating from 70 mph in 164 ft., what John Phillips of Car and Driver Magazine described as " Porsche territory ".

Other options include active shock absorbers ( ThyssenKrupp Bilstein GmbH's DampTronic, rebadged as PASM by Porsche ), ceramic disc brakes ( PCCB ), xenon headlights ( Hella's Bi-Xenon ) and an electronically controlled sport mode ( Sport Chrono Package ).

Porsche began experimenting with turbocharging technology on their race cars during the late 1960s, and in 1972 began development on a turbocharged version of the 911.
