A Porsche Boxster prototype has been spied making a pit stop at BMW's Forschungs und Innovationszentrum (FIZ) development facility in Munich, Germany. While this is a little strange, there could be a very logical explanation behind it - the Boxster is a hybrid.

Nothing is official, but a little deductive reasoning builds a pretty strong case for this argument. Firstly, Porsche CEO Matthias Mueller has already confirmed the company will offer hybrid variants of all models and BMW FIZ does development work on hybrids such as the 3-Series, 5-Series and i8. Furthermore, as of right now, the only hybrid system Porsche has is built around the supercharged 3.0-liter V6 which is likely to large to fit in the Boxster. Add in the fact that BMW isn't shy about sharing - as they have a hybrid partnership with PSA Peugeot-Citroen and an agreement to sell engines to Saab - it seems increasingly likely that the two company may be working together.

Regardless, the redesigned Boxster is expected to be unveiled sometime next year and could be offered with a 2.5-liter four-cylinder engine that produces up to 360 bhp (268 kW / 365 PS) in turbocharged guise.
