2012 Mercedes-Benz M-Class – Click above image for high-res gallery

Mercedes-Benz will launch its 2012 M-Class crossover in the U.S. this fall, complete with a range of four- and six-cylinder engines. Globally, the M-Class will be offered in ML250 BlueTec, ML350 BlueTec and ML350 BlueEfficiency designations.

The base ML250 will be powered by a 2.1-liter diesel four-cylinder, while the ML350 BlueTec uses Merc's reworked 3.0-liter diesel V6, which cranks out 258 horsepower and 457 pound-feet of torque. The diesel-burning 3.0-liter meets emissions standards in all 50 states and boasts reduced fuel consumption compared to the outgoing 3.0-liter oil burner. According to M-B, the revised Euro 6-compliant diesel bumps the ML350's fuel economy rating up to 20 miles per gallon in the city and 25 mpg out on the open highway. That's a mild improvement over the 2011 ML350's rating of 18 mpg city and 25 mpg highway.

Turning to the gas-powered ML350 BlueEfficiency, it uses the direct-injected 3.5-liter V6 found in the C- and E-Class vehicles. All three engines – two diesels and one gasser – will be hooked up a fuel-saving seven-speed automatic transmission. Look for the revamped M-Class to hit dealerships in September.

      20 city/25 highway for the diesel is excellent. Much better than the 16 city/20 highway on premium the gas v6 gets now. In fact, if those mpg numbers are right, the diesel will be beating their hybrid M-Class (20 city/24 highway on premium). I'm curious as to whether or not we will see the 4cyl diesel ML250 though? That one should be the fuel economy champ.

        The ML250 is for the European market, where the customers *really* care about fuel consumption and don't cry about "underpowered", when you have 100 hp per ton.

      I run a 2004 MB E270 CDi Auto which regularly gets 43 MPG ( US ) on a decent run at motorway speed over here in Europe !

      Another utterly useless vehicle by MB...the worst polluting fleet of vehicles to date.

        Never drove a diesel, have you. Modern diesels are amazing. The only thing better would be a diesel hybrid, but that would be terrible polluting to you, wouldn't it.

      Not very impressive to be honest...

        Get ready to be blown away. The era of the hybrids has come. Porsche's 918 coming out next year gets 100 miles to the gallon. It also holds the record for a street auto on the Nurburgring. The Jaguar CX-75 gets better than 100 miles to the gallon. It also does 0-60 in 2.5 seconds, the standing quarter in the nines at 156 and tops out at 213 mph. Then, there's the Audi R-8 that had 4 800 hp electric engines for a total of 3200 hp and 3318 ft pds of torgue at 1 rpm. They decided to make a very detuned version of the car because it didn't belong anywhere other than tractor pulls or smoking funny cars at the track.

      Nothing to get too excited about. I bet the 3.5L V6 gets the same crappy mileage as before.

      Are you saying that the 4 cylinder diesel is coming to the US? Check your facts.
