Porsche Boxster S
As Porsche enthusiasts already know, the “S” badge signifies a truly special model, not just a trim upgrade or option package. For 2003, the Boxster S carries on a Porsche tradition of transforming an already outstanding sports car into something truly special. Changes for the new model year involve performance, handling and content, and discreet exterior identification.
The Boxster S builds on the foundation of the standard Boxster and is powered by an exclusive, 3.2-liter, six-cylinder “boxer” engine that has been modified for the 2003 model year to provide 258 horsepower (SAE) and 229 lb.-ft. or torque. This enhanced powerplant works with a strengthened six-speed manual transmission and improved vehicle aerodynamics to propel the Boxster S from a standing start to 100 km/h (62 mph) in only 5.7 seconds, a figure two-tenths of a second faster than the 2002 version.
To produce this latest boost in the power output of the Boxster S engine, Porsche engineers used the latest VarioCam® technology, new Motronic ME 7.8 engine management controls, a “returnless” fuel supply system and an improved oil pump.
Formerly, the camshaft could be adjusted up to a range of 25 degrees, but this newest VarioCam technology allows infinite adjustment of the crankshaft angle by up to 40 degrees. This reduces charge cycle losses, improving power and mileage, and keeping exhaust emissions to a minimum. Porsche was the first manufacturer to introduce this integrated design, which it launched in the 911 Carrera.
