Its handling characteristics are superb; its level of safety is exceptional even in extreme situations. In short: the 911 GT3 places maximum performance at your fingertips at all times. Not just on the racetrack.' – Porsche Cars North America Inc.
Intended primarily for racing, though still road legal, the Porsche 911 GT3 can trace its ancestry all the way back through a succession of high-performance models to the legendary 911 Carrera RS of 1973.
The car takes its name from the FIA's GT3 category of production sports car racing, and has been produced in a variety of versions since its introduction in 1999 on the Type 996 iteration of the perennial 911. The 3.6-litre flat-six engine, though, departed from mainstream Type 996 practice by virtue of its water-cooled cylinders, leaving only the heads cooled by air.
Called the 'Mezger' engine after its designer, Hans Mezger, this unit was closely related to that of the Porsche 962 sports prototypes and the 911 GT1 racer.
In the GT3 it produced 355bhp, 59 horsepower more than in the standard Type 996, which was delivered to the road via a strengthened gearbox boasting interchangeable ratios.
To make the GT3 fit for track use, the brakes, suspension, and wheels were up-rated to cope with the substantial increase in performance, while aerodynamic downforce was enhanced by a larger front air dam and a rear spoiler. Weight reduction extended to the removal of the rear seats and most of the sound deadening, rear speakers, sunroof, and air conditioning, though the latter could be ordered as an option, as could a CD/radio.
There was also a 'Clubsport' package, comprising racing-type bucket seats, bolt-in half roll cage, six-point driver's harness, fire extinguisher, and a single-mass flywheel.
Where other 996s suffered both physically and reputationally from a somewhat over-hyped propensity to eat their own engines in a catastrophic and terminal fashion, the ‘Mezger’ engine in the Turbo, GT2 and GT3 was famously bullet-proof and trouble-free.
In its original Type 996 incarnation, as seen here, the Porsche 911 GT3 was produced up to 2006.
