2003 Porsche Carrera 4S

(from Porsche Press Release) The 2003 Porsche Carrera 4S combines the 3.6-liter, 315-horsepower (SAE) Carrera engine with the body, all-wheel drive chassis and feature content of the 911 Turbo, with only some minor design detail differences between the two models:

The front spoiler differs slightly; the Carrera 4S retains the automatic-deploying rear spoiler from the 911 Carrera instead of the Turbo’s two-piece wing; the Carrera 4S deletes the Turbo’s side intake ducts because these are only required to supply air to the turbo intercoolers; the C4S gets its own glass-reinforced plastic rear decklid with a reflector strip connecting the taillights.

The 3.6-liter engine – also shared with the 911 Carrera, Carrera Cabriolet, Carrera 4 Cabriolet and 911 Targa – produces 273 lb.-ft. of peak torque at 4,250 rpm, with at least 236 lb.-ft. available from 2,500-7,000 rpm. The engine uses VarioCam® Plus valve timing and lift system adapted from the 911 Turbo to help boost torque.

The 911 Carrera 4S can accelerate from zero-to-62 mph (100 km/h) in 5.1 seconds. A six-speed manual transmission is standard. The advanced Tiptronic® S five-speed automatic, which allows manual control, is available as an option. The all-wheel drive system uses a viscous multi-plate clutch mounted behind the front differential, sending five-to-40 percent of available torque forward depending on traction and power applied.

The standard solid-spoke aluminum alloy Turbo 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. The Carrera 4S shares the 911 Turbo suspension and 13-inch vented, cross-drilled four-wheel disc brakes.

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.

Safety technology includes a patented crumple-zone body structure, new seatbelt pretensioners and load limiters, dual front airbags, door-mounted side airbags, and anti-lock brakes (ABS).

The 911 Carrera 4S shares the additional standard luxury content of the 911 Turbo, which includes fully power-adjustable leather seats for the driver and passenger (with driver’s side memory), programmable remote entry and security system with alarm and immobilizer, and a digital audio system with an in-dash CD player.
