Porsche 911 Carrera
For 2003, the 911 Coupe and Cabriolet are powered by Porsche’s 3.6-liter, horizontally opposed six-cylinder “boxer” engine, which produces 315 horsepower (SAE) and 273 lb.-ft. of torque. A true sports car, the 911 Coupe weighs less than 3,000 pounds and sprints from a standing start to 62 mph (100 km/h) in 5.0 seconds on its way to a top test-track speed of 177 mph (285 km/h).
And, Porsche owners know that such speed is only part of the equation. The Porsche 911 Coupe and Cabriolet achieve optimum balance between performance and handling, between exciting dynamics and luxury amenities, and between active and passive safety technologies.
The 911 Carrera Coupe can accelerate from rest to 62 mph (0-100 km/h) in just 5.0 seconds, the Cabriolet in 5.2 seconds when equipped with the standard six-speed manual transmission. A five-speed Tiptronic® S automatic transmission remains an option for all 911 Carrera models.
Porsche offers a choice of two transmissions on the 911 Carrera models: a precisely shifting standard six-speed manual and the optional Tiptronic S five-speed automatic transmission. Porsche increased the torque capacity of the manual transmission for the more powerful 2002 models by using stronger alloy steel on key components. In addition, the output shaft runs in three bearings instead of two, and the differential uses stronger bevel gears. As before, a dual-mass flywheel ensures low vibration, and a hydraulic clutch provides consistent performance.
