Mercedes doesn’t do revolution when it comes to the M-class. Instead, the third generation of Mercedes’ midsize SUV is noticeably tame evolution, one that emphasizes more efficient engines, a more luxurious cabin and enhanced safety.
On sale this September and still built in Alabama, the new 2012 M-class seeks to blend off-road versatility with the kind of on-road manners expected of a Mercedes sedan. To find out more, we spoke to the development team in Stuttgart, Germany. Here’s what they had to say.
Sensible Styling
Anyone expecting a wholesale shift in Mercedes’ design language will be disappointed. This is a familiar-looking M-Class, blending hints of the full-size GL and compact GLK SUVs. The three-pointed star continues to dominate the grille and the prominent shoulder lines lead the way to a rear that emphasizes its width with taillights that echo the E-class.
Jan Kaul, the manager of the interior design, admits the overall concept was deliberately conservative and reflects the car’s global appeal. «The biggest markets are Germany and the U.S., but China and Russia are growing fast. »
Arguably the most challenging feature is to be found to the rear of the C-pillar, where the angular surfaces give place to an eccentrically curved rear window. «We tried different solutions,» says Kaul, «but we wanted to keep some of the influence of the original M-Class.» No less of an influence was a desire to optimize the aerodynamics, which Mercedes claims are class-leading. Careful attention was paid to the rear spoiler, the area around the windscreen and the front fenders, which integrate subtle spoilers.
Sedan-worthy cabin The cabin is more like an internal S-Class than ever, but seeks to assert clearly an SUV design language that is more upright and imposing. There's the familiar mix of knobs and switches, topped by a multifunction display – all of it a step above the previous board. Hartmut Sinkwitz curiously titled Mercedes Center Director of Interior Design Competition, now admits that customers see the M-Class as an alternative to a traditional sedan and expect a similar level of quality. While the environment for generations one and two was more utilitarian, the emphasis is on luxury and ornamentation.
The contrast with the poor quality of the original 2007, M-Class can not be greater. "The first generation car was actually a separate project," says Sinkwitz. "It was developed by a U.S. team and was influenced by the quality of its rival based vehicles. The M-Class was designed here in Stuttgart. The perceived quality is as important as reliability. This is essential to Mercedes. "
Mercedes never cut his list of options and owners can choose from a wide range of devices and combinations of colors including nappa leather panels and trims some ash particularly attractive. Sinkwitz admits he has some concern about the very richness of the election. While customers have the freedom to enjoy his eccentricities, traders will be able to suggest combinations of colors that stay on the right side of tasteful.
Regardless of your seat, all M-Class will be adapted for four. Mercedes customer research suggests that while the M-Class owners will occasionally lead to five, who prefer to optimize the comfort of a quartet of luck. "If you need more space, we offer the R-and GL-Class," says Sinkwitz.
Each Class M also have all the safety features for the last time in the toolbox Mercedes. Highlights of the festival stands up to nine airbags including a support system and the attention it tries to keep awake if you start falling asleep. "In the U.S., 47 percent of the M-Class customers are women," said Dr. Joachim Schmidt, Executive Vice President of Sales and Marketing. "For them, security is a key priority. "
Efficiency is the key under the cover can be seen as M-Class SUV gas-guzzling, but Mercedes is talking about his newly discovered thanks to the fuel efficiency of a new range of BlueTEC diesel and gasoline engines BlueDIRECT to be offered in the U.S.
The ML350 CDI gets a new version of Mercedes turbodiesel 3.0-liter V6. Peak Output rises from 231 to 258 horsepower and 398 to 457 pound-feet of torque. No EPA estimates are available yet, but Mercedes says the engine delivers about 32 mpg in the European cycle. Taking into account that about 15-20 percent of the M-Class vehicles sold in the U.S. are now diesel-powered, this model could become a much bigger part of the lineup in the coming years.
On the gasoline side, the ML350 4MATIC BlueEfficiency will be powered by a 3.5-liter V6 direct-injection engine rated at 306 hp and 273 lb-ft. Acceleration from 0-60 takes 7.6 seconds, and top speed is 146 mph. It will be joined later by what Mercedes is calling its «international engine,» a 4.6-liter twin-turbo V8 offering up 408 hp and 516 lb-ft of torque.
Across the range, Mercedes is claiming a 10 percent improvement in fuel efficiency, achieved through a range of measures. Electro-hydraulic steering is standard, together with auto-stop/start technology connected to a seven-speed automatic transmission, which taken together equate to almost a quarter of the efficiency savings. In Europe, this efficiency drive will manifest itself in an eco-focused model powered by a 2.1-liter turbodiesel offering a range of up to 750 miles with a 23.8 gallon tank. This model won’t be crossing the Atlantic, although the engine may feature in a U.S.-bound C-Class.
Farther down the line, there’ll be a V8-engined AMG version and a hybrid.
On- and Off-Road Versatility
The project leader for the ML, Dr. Uwe Ernstberger says that «Mercedes customers expect a high level of off-road ability.» That’s news to us, but Mercedes took the idea seriously enough that it will offer an off-road package beginning next year. It adds an underbody skidplate, two-speed transfer case, center differential lock and an enhanced air suspension that allows a maximum ground clearance of 11.2 inches and a fording depth of 23.6 inches. There is also a Land Rover-style electronic system that provides six transmission modes: one automatic, two off-road and three on-road modes covering winter, sport and trailer-pulling.
Even if you don’t opt for the extra hardware, every M-Class will still feature Mercedes’ 4MATIC four-wheel drive system along with traction control, and an ABS system that has been tuned for off-road work. Back on terra firma, the ML is promising greater agility. Air suspension is standard but you can upgrade the system to include adaptive damping and an Active Curve system that acts to minimize body roll through corners. Couple this with wheels that go up to 21 inches, and you have an SUV that should deliver plenty of on-road performance.
Final Thoughts
Mercedes officials claim the key attributes of the new M-Class are defined as «efficiency, capability and safety.» This might not be a slogan to excite enthusiasts, but it will no doubt play well to the SUV’s core constituency. Mercedes has sold over 1.2 million M-Classes since 1997, so it was never likely to take a big risk. This new SUV is predictably predictable, but that’s unlikely to stop it from being a huge success.
