Porsche unlocks secrets of its mid-engine 911

Porsche is beginning to realize that it's sitting on a goldmine of automotive history with its secret vault full of rare cars. Autoblog toured it a few months ago, and they were amazed at all of the curiosities hidden inside. Now, it's starting to let more folks in thanks to a new series of YouTube videos. The first covered the 965 prototype that shoved a water-cooled, Audi V8 into one of its cars. Next up, a mid-engine 911 that acted as the powertrain test mule for the Boxster.

The Porsche 911 is inextricably linked to its rear-engine layout. They go together like peanut butter and jelly. However, at the time Porsche was developing the Boxster, the company didn't want to lay all of its cards out of the table during testing. As opposed to using camouflage, it put a whole different car on top. The prototype looked just like any other 911 Targa of the day, but the biggest giveaway that something was amiss was the heavily tinted rear window. By obscuring it, inquisitive journalists couldn't peak at the new engine that replaced the backseat.

It might not look like anything too important on the outside, but this is a major piece of Porsche Boxster history underneath.
