The third generation of the Mercedes-Benz M-Class sets new standards in the SUV sector, and particularly impresses with its low fuel consumption and emission figures. Compared to the previous series, the entire model range of the new M-Class consumes an average of 25 percent less fuel. Outstandingly, the ML 250 BlueTEC 4MATIC is content with an NEDC consumption of 6.0 l/100 km (158 g CO2/km) and can travel up to 1500 kilometres on a single tankful. Efficiency notwithstanding, the fascination of the M-Class with its unique synthesis of agility, driving pleasure and comfort is fully preserved.
In the ML 250 BlueTEC 4MATIC, the 3.0-litre V6 of the previous ML 300 CDI BlueEFFICIENCY 4MATIC model is replaced by the thrifty four-cylinder power unit already familiar from the S-Class. The NEDC consumption of 6.0 l/100 km is 28 percent lower than that of the previous model. Thanks to AdBlue® exhaust aftertreatment, the diesel meets the EU-6 standard due to come into force from 2014.
The calculatory range with a full tank of fuel is particularly impressive. With an NEDC consumption of 6.0 l/100 km, the ML 250 BlueTEC 4MATIC with the standard 70-litre tank can cover around 1170 kilometres between fuel-stops. If the vehicle is fitted with the optional 93-litre‑tank, the car can even cover up to 1500 kilometres between fuel-stops.
The excellent fuel economy is underpinned by a comprehensive package of BlueEFFICIENCY measures, as well as by this state-of-the-art engineering. In addition to the ECO start/stop function that comes as standard, these measures include the new seven-speed 7G-TRONIC PLUS automatic transmission with a new fuel-economy converter, low-friction bearings and a transmission oil thermal management system. Low-friction axle drives, electric steering, the optimised belt drive, the on-demand control of all ancillary components and pumps, and tyres with low rolling resistance also play their part in reducing fuel consumption. What's more, intelligent lightweight design has stopped the weight from spiralling upwards.
With a drag coefficient of Cd = 0.32, the new M-Class (ML 250 BlueTEC) also sets a new best figure for this vehicle class. The key factor determining the low wind resistance is the aerodynamic efficiency of the basic body shell, including the optimised design of the front bumper, the A-pillars and the roof spoiler, plus numerous other detailed improvements.
