Spy pictures of the next-generation Porsche 911 Cabriolet have surfaced. It has current-car headlights and a soft top, but changes are imminent at the rear.

The next-generation Porsche 911 (998) Cabriolet is coming along quite nicely as these spy pictures will attest. Taken during some hot weather testing the images show a slightly longer body made to increase rear seat space. The front end features 997-style headlights which are raised to meet safety regulations.

Expect to see radical changes to the rear lights where LED technology will be used. That massive camouflage rear spoiler won't make production; it's just there to hide the real deal. The current hard-top bug sweeping other supercar makers has not yet bitten Porsche. Thus only the traditional canvass is to be fitted on the roof.

The 911 Cabriolet is one of the most expensive and exclusive 911s in the range. As such very high technologies like the 7-speed PDK transmission and PASM (Porsche Active Suspension Management) are to be employed. All performance indicators will be improved with the next-generation, including top speed, fuel economy, C02 emissions and handling.

Almost every 911 model in the current range has a Cabriolet version, from the Carrera up to the Turbo. The latter makes a heady 368kW (500hp) and does 0 - 100km/h in 3.8 seconds.
