Porsche Boxster S - 2003 Model

191 kW (260 bhp) and even more torque

The Boxster S has evolved in every respect. The six-cylinder horizontally-opposed power unit now develops maximum output of 260 bhp (191 kW) at 6200 rpm, maximum torque increasing to 228 lb-ft (310 Nm) at 4600 rpm. Acceleration from 0–62 mph takes 5.7 seconds and top speed is now 164 mph (264 km/h). Despite this increase in power and performance, fuel consumption is down by 2 per cent, mainly due to Porsche's new VarioCam technology adjusting the camshaft continuously up to an angle of 40° and thus helping to further reduce charge cycle losses in the process.

Modified six-speed manual gearbox

The six-speed manual gearbox featured as standard in the Boxster S has been appropriately modified in line with this increase in power and performance. To efficiently handle the higher torque, the single-plate dry clutch has been reinforced and exerts higher contact pressure. The individual transmission ratios are unaltered and the five-speed Tiptronic S transmission, combining supreme comfort with road performance, remains as an option for Boxster S.

Reduction of unsprung masses

New 17-inch light-alloy wheels developed specifically for the Boxster and 18-inch light-alloy wheels introduced originally on the 911 Carrera significantly reduce unsprung masses and, as a result, ensure even more sensitive and precise suspension and shock absorption. The slim spokes of the new 17-inch wheels, fitted as standard on the Boxster S, bear testimony to the consistent application of lightweight design and technology, saving 2 kilos on the car’s previous wheels. And the 18-inch wheels, available as an option on both the Boxster S and the Boxster, reduce weight by an even more significant 10.8 kg or 23.8 lbs, equal to a weight reduction of 22.1 per cent.

Soft roof with a rear glass window

The roof now moves down to the rear lid at a steeper angle, closely resembling the aluminium hardtop available as an option. This new shape is the result of a new, fourth roof bracket fitted above the rear window which is now made of glass. Replacing the plastic rear window of the former models, the new heated rear glass window improves visibility to the rear and motoring comfort in cold and wet weather. The glass window does not alter the time required to electrically lower the roof, which remains at a record 12 seconds as a result of the new roof kinematics.
