From Porsche press: For the 2005 model year, engines are substantially more powerful, yet also more fuel efficient in both the Boxster and Boxster S. New five- and six-speed manual transmissions feature shorter, crisper gear changes and Tiptronic® S gearboxes have been upgraded. Variable-ratio steering is standard equipment, and the steering column both tilts and telescopes to enhance driver control and comfort. Driver and passenger both benefit from redesigned and roomier interiors and four seating choices.
Wheels and tires are larger and brakes are upgraded. Porsche Stability Management becomes part of a long list of standard equipment, with Porsche Active Suspension Management, Porsche Composite Ceramic Brakes and the Porsche Sports Chrono Package added to the options list.
The Boxster’s new headlamps have the traditional Porsche look. Separating headlamps from other front lighting, which allows fog lamps to be placed lower and further from the car’s centerline, thus they are better positioned to light the way through fog or snow. At the same time, the primary headlamps are designed to enhance the driver’s lateral illumination.
Boxsters continue to be powered by Porsche’s horizontally opposed “flat” six-cylinder “boxer” engine architecture. While engine displacement remains 2.7 liters for the Boxster and 3.2 liters for the Boxster S, both engines have been extensively revised to provide substantially more power and to provide it more efficiently.
Horsepower increases dramatically, for the Boxster from 225 a year ago to 240 (SAE) in the second- generation car, and for the Boxster S from 258 last year to 280 (SAE) now. But just as impressive is the way torque is delivered right where it’s needed. The Boxster accelerates from a standing start to 60 miles per hour (97 km/h) in less than six seconds and the Boxster S accomplishes the same feat in just 5.2 seconds. But the most dramatic improvement is in pulling power for passing, even in the low-to-middle section of the rev range.
Top speed on the test track for the Boxster is 159 mph (256 km/h) and 167 mph (268 km/h) for the Boxster S.
