The EPA (Environmental Protection Agency) fuel economy figures for Infiniti's all-new M35h are finally out. According to the government agency, the Japanese brand's first-ever hybrid model returns an estimated fuel economy of 27 mpg in the city, 32 mpg on the highway, and 29 mpg on the combined cycle.
For comparison, the conventional M37 with a 330HP 3.7-liter V6 is rated at 18 mpg City and 26 mpg Highway, while the M56 that is powered by a 420HP 5.6-liter V8, at 16 mpg City and 25 mpg Highway.
The M35h's drivetrain pairs a 3.5-liter 24-valve V6 engine with 306HP to a 50 kW [68HP] electric motor for a system net output of 360 horsepower. Both the gasoline V6 and electric motor deliver their power to the rear wheels via a 7-speed automatic transmission. Infiniti says the 1.830 kg (4.035 lbs) luxury sedan can reach 62mph (100km/) from standstill in 5.5 seconds en route to a top speed of 155 mph (250 km/h).
According to the Japanese automaker, the M35h can drive on electric power alone at speeds up to 62 mph for a distance of up to 1.2 miles at a time.
U.S. sales of the 2012 M35h will start this spring.
