I found this article and these photos about the unveiling of the new 2011 R class from Mercedes-Benz at eMercedesbenz.com. These photos show the first redesign and update for the R class that was originally introduced in 2006.

The biggest changes look to be to the front of the R class. Design cues from the rest of the Mercedes-Benz SUV line up are evident. All of the new Mercedes-Benz vehicles seem to be influenced by the Mercedes-Benz “halo” vehicle, the new SLS Gullwing. It seems that all Mercedes-Benz styling is moving towards a more upright front grill, like you see on the SLS, lights on the R have also changed, LED running lights have been added as well.

The R class, while a bit difficult to categorize, is a great, versatile vehicle. It’s roomy for passengers, very comfortable for long distance road trips, and not obnoxiously big like some SUVs. But what is is really? A wagon, SUV, crossover? I guess it doesn’t really matter, if you’ve got people or cargo to haul in style and comfort, it’s a great option. 

From eMercedesbenz.com:

Mercedes-Benz is celebrating the world premiere of the redesigned 2011 MY R-Class luxury crossover at the New York International Auto Show, open to the public April 2-11, 2010 at the Jacob Javits Center. The 2011MY R-Class combines the spaciousness of a luxury SUV with the safety, style and exclusivity of a Mercedes-Benz sedan.

Powered by a 3.5-liter V6 gasoline engine, the R350 4MATIC produces 268 hp and 258 lb-ft. of torque, while the R350 BlueTEC 4MATIC features a 210-hp 3.0-liter turbodiesel delivering an impressive 18 mpg city and 24 mpg in the highway driving cycle. Available in 6- and 7-passenger seating configurations, all models feature the sure-footed confidence of standard 4MATIC all-wheel drive.

Bold New Look

One look is all it takes to see that the new MY2011 R-Class conveys a new level of assertiveness, underscoring the unique personality of this multi-talented vehicle. The completely redesigned front end completely transforms its overall appearance, taking its inspiration from Mercedes-Benz sedans and SUV models. Alongside its fresh exterior, the inner values of the redesigned MY2011 R-Class also speak for themselves. These include the spaciousness of a luxury SUV, as well as the safety, style and exclusivity of a Mercedes-Benz sedan. At the same time, the latest generation offers the interior versatility central to the R-Class vehicle concept, while also delivering the all-weather confidence of 4MATIC allwheel drive as standard (U.S. models only). The R-Class celebrates its world premiere at the New York International Auto Show (NYIAS) March 31, 2010.

Efficient Engines

For the U.S. market, the R-Class is offered with a choice of two fuel-efficient engines. The R350 4MATIC delivers 268 hp and 258 lb-ft of torque, yet achieves an estimated 14/19 mpg (city/hwy), while the R350 BlueTEC 4MATIC is one of the world’s cleanest diesel vehicles. The V6 turbodiesel engine generates an output of 210 hp (155 kW) and an impressive torque of 400 lb-ft. Equipped with the highly-effective AdBlue© exhaust treatment system for low emissions, the diesel engine achieves an estimated 18/24 mpg (city/hwy).

A New Level of Style and Versatility

The redesigned R-Class features an assertive new design, further emphasizing the unique personality of this multi-talented vehicle. Designers focused their attention on completely restyling the front end, giving the R-Class a look that is both harmonious and powerfully dynamic. In addition to the hood, fenders, radiator grille, front fascia, headlamps and bumpers — with chrome simulated under guards — have all been completely redesigned. The face of the R-Class can be further enhanced with chrome trim incorporating optional LED daytime running lights in combination with bi-xenon headlamps.

Viewed from the side, the R-Class sets itself apart from conventional crossovers with the coupe-like line of its windshield and its distinctive, redesigned exterior mirrors and wheels. U.S. models feature standard 5-spoke, 19-inch wheels, with a 20-inch rim available on the R350 4MATIC as part of the Sport package. International market versions offer 5-spoke, twin 5-spoke and 10-spoke designs ranging from 17 to 21 inches (43.2 to 53.3 cm). The front-end design language continues through to the rear of the R-Class, with a restyled rear bumper with reflectors, standard LED rear taillights and integrated exhaust pipes.
