Porsche celebrates 20 years of the 911 GT3. This now iconic model first debuted in 1999 at the Geneva Motor show on the 996 generation. The focus was to eliminate every feature that added unnecessary weight to the car in pursuit of ultimate performance.

Sound deadening material, rear seats, rear loudspeakers, and the sunroof were completely removed, while air conditioning and a CD player/radio could be optionally deleted or included in the car at no cost. This was a modern 911 at its most pure form, complete with a naturally aspirated engine, manual transmission and rear-wheel drive.

These measures made the 911 GT3 one of the fastest and most athletic cars you could drive on the road legally. Since its debut, race-tuned versions of the 911 GT3 have won numerous endurance races including 24 Hours at Spa, Daytona and even 7 endurance victories at the Nürburgring.
