With the world premiere of the ML 450 hybrid, Mercedes-Benz is setting the first of a total of five accents at the 2009 New York International Auto Show. The new ML 450 hybrid is the first full hybrid from a European manufacturer and was specifically developed for the North American market. The ML 450 hybrid consumes almost 50 percent less than the ML550, although it boasts over 90 percent of the maximum power generated by the V8 model. 

Mercedes engineers have combined the all-new four-cylinder diesel engine with BlueTEC, the technology of the world's cleanest diesels. The outcome is the most fuel-efficient and cleanest diesel model in this vehicle class, according to Mercedes. The ML 450 hybrid has a range of up to 44 mpg. Thanks to highly effective exhaust gas treatment, the E 250 BlueTEC fulfills the U.S. Bin 5 and ULEV emissions standards, which are among the toughest in the world. At the same time, the four-cylinder offers a level of engine refinement and performance on a par with that of a six-cylinder, thanks to its high torque (381 lb-ft / 500 Nm), 7-speed automatic transmission and Lanchester balancing shafts. 

The performance figures for the ML 450 hybrid (335 hp, 381 lb-ft) are at the level of a classic eight-cylinder SUV with permanent all-wheel drive. Conceived specifically for the North American market, the ML 450 hybrid achieves highway gas mileage of 24 mpg (21 mpg city), making it the most efficient vehicle in its segment. Classified as a SULEV (Super Ultra Low Emission Vehicle), the SUV complies with the strictest current U.S.emissions standard. At the same time, the ML 450 hybrid guarantees a refined driving experience combined with increased driveline comfort with a system output of 335 hp and an overall torque of 381 lb-ft (517 Nm). The powertrain is controlled fully automatically, meaning that the driver can concentrate on the traffic and enjoy the driving experience of the ML 450 hybrid without additional operational effort.
