Mercedes-Benz S400 Bluetec Hybrid Concept

Mercedes-Benz has taken its Bluetec V-6 diesel engine and mated it with a hybrid system. Result? Claimed fuel economy of 40 mpg on the highway (European test cycle) and acceleration to 60 mph in a shade over seven seconds, which is none too shabby. Also not surprising given the 265 horsepower and 465 lb.-ft. of torque produced by the dual power plant. Mercedes says the car will arrive in the States after 2010. Beyond those tidbits, very few details were parceled out.
