Last week we spotted the 2012 Porsche 991/998 Cabriolet, the doors will be replaced with the current cabriolet version and other shared components from the Boxter and Caymen.

This 991/998 Cabriolet sports a new technology on the roof which improves on the previous cabriolet models.

The 998 model will have a longer and wider wheelbase than the current model and the spy shots show its wider stance. Changes are incorporated to meet the latest crash requirements and to improve aerodynamic downforce and driving electronics.

Electronic features include an integrated torque vectoring system on four-wheel-drive models and a faster-acting limited-slip differential on rear-drive 911s. The 911 will get LED front and rear lights as standard fitment.

Regarding the powertrain, Porsche will implement updated versions of the current 911’s 3.6 and 3.8-litre flat sixes. Light-pressure turbocharging is being developed to boost efficiency, but these developments won’t be seen until the 998 receives its facelift in 2015, These spyshots hint at the Turbo with the vents but we can reveal these are camouflage stickers.

Easy noticeable on the spyshots is the disguised active spoiler. It uses the same active technology seen on the Panamera.

It will extend at high speed to boost downforce without shaving the speed off at high speed due to drag improvements.
