The 2003 Porsche 911 Turbo all-wheel-drive coupe was powered by a twin-turbocharged 3.6-liter horizontally opposed six-cylinder engine that produced 415 horsepower. An optional X50 engine performance package, which boosted horsepower to 444, was also available.
A six-speed manual overdrive tranmission was standard, while a five-speed automatic Triptronic transmission, with an on-shifter gate and steering-wheel-mounted controls for manual shifting, was optional.
Porsche's all-wheel-drive system was also part of the package.
Porsche added an in-dash CD player to the Turbo's standard AM/FM audio system for 2003. Other features included air conditioning, leather seats, dual front and side airbags, a keyless entry system, power heated mirrors, cruise control, an anti-theft alarm system, a telescopic steering wheel, and a leather-wrapped steering wheel, as well as powered windows, steering, brakes, and door locks.
The 911 Turbo was also equipped with a special Turbo tachometer, four-wheel anti-lock brakes, fog lights, 18-inch alloy wheels, upgraded brakes and suspension, bi-xenon high-intensity headlights with headlight cleaners, and a rear spoiler.
The 2003 Porsche 911 Turbo was one of a long line of near iconic Porsche sports cars that promised a lot to drivers, and delivered on those promises in almost every way. Drivers noted that the car's power, handling, precise steering, braking, suspension, and interior all met or exceeded expectations. Drivers also noted that visibility out the rear was exceptional, as was reliability.
