The video contains both exterior and interior footage of the new 2012 BMW 3 Series (F30) sedan. The car in question is a diesel, has a start/stop system and is limited to 210 kph (130 mph) for test purposes. The day this video was shot, BMW also tested the 3 Series while pulling a trailer (see the beginning of the video).
Like BMW, Mercedes-Benz, Aston Martin, Citroën and SsangYong were testing their newest cars in the Sierra Nevada (Spain) that day. This video also contains a test version of the Aston Martin DBS (evolution rather than revolution?) and two uncamouflaged Citroëns DS5.
At the IAA in Frankfurt (September), BMW will probably reveal its newest model.
