Porsche engineers were caught on film recently testing the next generation of the Boxster roadster that is due to be revealed at a major international motor show sometime next year.

The Boxster prototype looks no different from the current model, but that shouldn't come to as a surprise to Porschephiles that are used to the company's evolutionary approach to design.

The new Boxster will share many parts with the next 911 while the German engineers will most likely try to further reduce the car's weight to improve handling as well as to boost fuel efficiency.

The engine line-up and transmissions including a six-speed manual and seven-speed dual clutch PDK will be carried over with minor changes from the current model.

There have been rumors circulating around the net that Porsche may also introduce a smaller displacement yet powerful four-cylinder engine, however, this has not been confirmed.

Sales of the next generation Boxster will most likely start towards the end of 2011 or early 2012.
