Porsche has released more details on their upcoming Boxster Spyder, ahead of its unveiling at the LA Auto Show.

The engine being used comes out of the Cayman S. It develops 315bhp, compared to the 305bhp of the Boxster S, and revs to 7500rpm.

The car will weigh just under 1275kg, making it lightest car that Porsche makes today. Equipped with a seven-speed PDK gearbox and a Sport Chrono Plus package, it’ll get from 0 to 60mph in just 4.8seconds.

They’ve saved weight by fitting aluminum doors, an aluminum rear deck, lighter bucket seats and a lighter roof. The car also comes without air-con and a radio as standard.

There have also been some modifications to the chassis and suspension, including a 20mm drop in ride height and stiffer springs. To contribute even more to handling, the track has be widened both at the front and rear.

The alloy wheels are the lightest that Porsche offers, weighing less than 10kg each. They come with high-tech compound tires which can be ran at lower than normal pressures.

Other changes from the Boxster S include a different steering box, different front brakes and a limited-slip diff as standard.

There’s bad news too though. With the roof up, you can’t drive at more than 124mph, and Porsche doesn’t recommend that you drive it through an automated car wash.
