Mercedes shows off new 2011 R-Class crossover

Mercedes-Benz is giving its big R-Class luxury crossover a new look.

But while some others are reducing their size, the Mercedes will stay true to its roots with the R-Class. It will come in either six- or seven-passenger versions.

It will come with two engines. The 3.5-liter V-6 gasoline engine in the R350 4MATIC produces 268 horsepower. The 3-liter turbo-diesel in the R350 BlueTEC 4MATIC develops 210 horsepower -- and 18 miles a gallon in the city and 24 mpg on the highway. All will have all-wheel-drive.
