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.

Le Mans echoed to the sound of racing cars on Easter Sunday as teams took part in the sole scheduled test day, and Audi's new R18 coupe dominated the LMP1 class. Le Mans 2011: classes and rules changes The Automobile Club de l'Ouest (ACO), the organisers of the annual 24-hour race, made several changes to the competition classes and technical specifications for Le Mans 2011, aimed at reducing costs, raising lap times and ending the dominance of turbodiesel endurance racers. Out went V10 and V12 engines in the LMP1 (Le Mans Prototype) class, and in came new capacity limits for all engines, intake restrictors and lower turbo boost limits on existing turbodiesels. Naturally aspirated petrols units are now limited to 3.4-litres, turbo'd petrols can be no bigger than 2.0, and turbodiesels are restricted to 3.7-litres.
