2003 Porsche 911 Turbo

The 2003 Porsche 911 Turbo continues a performance legend begun when the first 911 Turbo was introduced to North America in 1976. With a 415-horsepower (SAE) twin-turbo engine and advanced all-wheel drive, the latest 911 Turbo takes its place in the top echelon of the supercar category.

Derived from the Porsche GT1 racecar, the 3.6-liter, horizontally opposed six-cylinder engine sustains 415 lb.-ft. of peak torque from 2,700-4,600 rpm. In place of a conventional throttle cable setup, the E-Gas electronic throttle transmits pedal position to the engine control unit.

Power drives through a standard six-speed manual transmission. The advanced Tiptronic® S five-speed automatic transmission is available as an option.

The 911 Turbo can accelerate from 0-62 mph (0-100 kph) in just 4.2 seconds. On the test track, the 911 Turbo can sprint from a standstill to 100 mph (160 kph) in only 9.2 seconds and achieve a top speed of 189 mph (305 km/h).

An optional engine enhancement performance package increases the twin-turbo engine’s output to 444 horsepower (SAE) and 457 lb.-ft of torque.

The standard Porsche Stability Management system (PSM) can detect a loss of grip at the front or rear and reduce instability by applying braking to individual wheels and, if necessary, altering engine power.

The upper part of the two-piece rear stabilizer wing automatically rises at speeds above 75 mph (120 kph) and lowers at speeds below 50 mph (80 km/h).

The standard aluminum hollow-spoke alloy wheels measure 18 x 8 inches in front and mount 225/40 ZR18 tires; the 18 x 11-inch rear wheels mount 295/30 ZR18 tires. Also derived from the GT1 racecar, one-piece, four-piston monobloc brake calipers reduce unsprung weight and heat and feature 13-inch (330-mm) vented, cross-drilled discs front and rear.
