2005 TechArt Boxster Widebody

Athletic beauty: The TechArt Widebody based on the Porsche Boxster of the 987 model range doesn’t only offer spectacular design but also extra driving fun and agility. After the huge success of the Widebody concept for the first Boxster generation, TechArt Automobildesign developed a wide body version for the current version of the roadster.

With the add-on fender flarings on front and rear axle the TechArt Widebody is eight centimeters wider than the standard car. The front extensions don’t only provide extra room inside the wheel houses but also improve the deventilation of the heated up air with their integrated wheel-house ventilation. The rear flarings are equipped with largely dimensioned air ducts to bring fresh air to the centrally placed engine.

Apart from spectacular, sporty design the TechArt designers of course paid attention to optimal aerodynamic efficiency. The TechArt front spoiler bumper reduces the lift at the front axle and improves the cooling of the front brakes with large air ducts. The TechArt rear apron with integrated diffuser rounds out the conversion.

Extremely broad wheels and tires make the TechArt Widebody concept for the Boxster complete: Specially for this wide body version they developed custom-made versions of the one-piece TechArt Formula five spoke wheel. The front axle is equipped with wheels in size 8.5Jx20, the rear axle is equipped with 11Jx20 wheels.

After extensive test drives, TechArt Automobildesign recommends ContiSportContact 2 high performance tires in sizes 235/30 ZR 20 front and 305/25 ZR 20 rear for the Widebody based on the Porsche Boxster. The height-adjustable TechArt sport suspension is specially set-up for these ultra-wide wheels and tires and the wider track of the car. The coil-over suspension doesn’t only provide an individual damping of the roadster but also lowers the two-seater car by some 25 millimeters. Boxster models with PASM system can be updated with the sporty set up TechArt coil over sport suspension.

TechArt also offers engine tuning for the Widebody. The two watercooled six-cylinder boxer engines can be upgraded with the TechArt power kits. They each consist of a sport air filter and newly programmed engine electronics. The result: 15 hp / 11 kW extra power and optimized road performance.
