BMW Vision Efficient Dynamics (2009) teaser video

By Ben Pulman First Official Pictures 28 August 2009 12:49 BMW has launched a teaser video for the Vision EfficientDynamics sports car concept that it will unveil at the 2009 Frankfurt motor show – and we've today published a new (sadly teaser again) photo of the green coupé from our friends over at IAAblog.com Not a lot until the final few sequences when we get to see the rear of this eco-friendly concept car. It shows the back of the sports car with F1-inspired winglets and other body addendum, plus external rear lights. BMW announced the car at the same time it confirmed its withdrawal from F1, claiming the concept would ‘demonstrate how efficient a sports car can be’ and that it ‘will also prove that sustainability does not apply to the drive train alone, but to design and materials as well.’ There’s been no hint from Munich on the powertrain, but in line with the other cars BMW will reveal (the X6 and 7-series ActiveHybrids) the Vision EfficientDynamics concept will almost certainly feature hybrid drive.

McLaren P1: Paris 2012

The McLaren P1 – spiritual successor to the iconic McLaren F1 – has been publicly revealed at the 2012 Paris Motor Show. Still, we do have more details on the P1 concept that McLaren say will turn in to a production car in 2013 before it finds its way in to the garages of wealthy McLaren customers in 2014. The McLaren P1 is designed to be “…the best driver’s car in the world on road and track” according to McLaren, which is setting the bar a bit higher than high, and the concept P1 at Paris is – at least in terms of what we can see – 95 per cent of what the production model will be.

60 years of Unimog spawns off-roader concept

Mercedes-Benz is paying tribute to 60 years of Unimog trucks with a mean, green off-roader concept that the company claims stands for future versatility in vehicle design. In a nod to the first Mercedes Unimog--built in 1951 and reinstated with the 2010 product range--the team of Mercedes and Daimler designers gave the 2011 design concept an open cab. They injected the U 5000's off-road capabilities into the equation as well, drawing on the truck's historic design strengths.
