The 2000 Porsche Turbo was offered with an option named X50, which added more power.
The 2004 Turbo S version came fitted as standard with that and added more goodies.

The 2004 Porsche Turbo S was a surprise for the market. It was the more powerful version of the 2000 911 Turbo. While it wasn’t the quickest Porsche ever made, it was more performance-focused than its non-S sibling.

From the outside, the front bumper attracted views due to its large three air-intakes needed to cool the radiators like the non-S version, but a lip was added under the apron. On its sides, another pair of air-intakes needed to feed the big turbochargers were installed in front of the rear wheels. The wide rear fenders looked muscular. The rear “duck-tail” spoiler was fixed.

Inside, the Turbo S was similar to the Turbo version but included a 6-CD changer. The classic, five-dials, instrument cluster featured an aluminum background for the gauges instead of black ones. On the options list, there were new seating options.

The Turbo S was the quickest and fastest from its lineup. With a 0-100 kph (0-62 mph) under 4 seconds, it was a fierce competitor for other supercars on the market. On top of that, it featured an all-wheel-drive system, which was better in slippery conditions. The Porsche Carbon-Ceramic Brakes were fitted as standard, and the adjustable dampers offered a higher cornering speed. It was available with a 6-speed manual or a 5-speed automatic gearbox (Tiptronic) with manual override to change gears and paddle shifters.
