Mercedes-Benz ML 450 hybrid - Up to 34 MPH on battery alone

The road to production for the Mercedes-Benz ML450 hybrid hasn't always been smooth, but now that the Germans have shown off the new SUV here at the New York Auto Show (following its early debut at the 2007 Frankfurt Motor Show), they'll be happy to tell you just how amazing and luxurious this SULEV people-hauler is.

The numbers start with a respectable 21 city/24 highway mpg rating. With a 3.5-liter V6 Atkinson cycle engine and a 288V NM battery pack, the ML450 hybrid can go 1.8 miles and up to 34 mph on battery power alone (take that, Toyota Prius!). The hybrid powertrain altogether has a combined output of 335 horsepower, so providing adequate power to move the giant SUV was clearly just as large a priority as fuel economy. The ML450 hybrid features Mercedes' first application of the Two-Mode hybrid powertrain it co-developed with General Motors and Chrysler - similar applications also appear in the Chevrolet Tahoe Two-Mode Hybrid, Dodge Durango and Chrysler Aspen Hybrids.
