Debuted in 2000, the Porsche 996 Turbo succeeded the 993 Turbo and was the first water cooled production 911 Porsche. The 996 Turbo utilized the GT1 engine, like it's race-bread brother, the GT3, and featured twin-turbos that produced 420 Horsepower. Putting the power in motion was the all wheel drive like its predecessor.
The coefficient of drag is 0.32. The Turbo had different headlights compared to the regular Carrerra and Carrera 4. The Turbo introduced the large vents in the front and rear bumper and was later copied onto the Carrera 4S and Cayenne Turbo. The 996 was highly criticized due to the sharing of parts with it's little sister, the Porsche Boxster. Owners that shelled out over $100,000 for their new Turbo's were not thrilled to see the lesser priced model running around with the same headlights and interior bits for half the price. It was simply a numbers game for Porsche. Porsche was able to cut costs by sharing parts between 5 models, while also increasing sales by introducing the first automatic "Tiptronic" or "tip" transmission.
For and additional $17,000 US, the X50 package could be added, boosting the power to 450 Horsepower, and 457 ft lb of torque. With this package the car could do 0-62mph in 3.8 seconds.
The Turbo S is the exact same thing as the X50 package. It was named the Turbo S in Europe, and later towards the end of the 996 life cycle, the 996 Turbo S coupe and Turbo S Cabriolet replaced the X50 package and made it's way to the US
Styling-wise(coefficient of drag:0.32), the car was more individual than previous Turbos. Along with the traditional wider rear wings, the 996 Turbo had different front lights and bumpers when compared to the Carrera and Carrera 4. The rear bumper had air vents that were reminiscent of those on the Porsche 959 and there were large vents on the front bumper, which have been copied on the Carrera 4S and Cayenne Turbo.
