The new Infiniti M Hybrid – or M35h – has been officially rated by EPA (Environmental Protection Agency. Estimated fuel economy is 27 mpg City, 32 mpg Highway, with Combined fuel economy rated at 29 mpg.

32 American mpg is about 6.0 liter per 100km or 40 UK mpg, but before you say that’s not very astonishing you have to remember this is a luxury sedan weighing more than 1.8 tons powered by high performance 360 hp powertrain that enables it to go from 0 to 60 mph in 5.5 seconds. Given the performance and convenience it delivers, that is actually pretty good.

The Infiniti M35h features the all-new Infiniti Direct Response Hybrid™ system, an advanced one-motor, two-clutch parallel hybrid design that utilizes precise, high-speed motor control technology enabled by the powerful Lithium-ion battery, allowing power to be delivered directly to the vehicle’s 7-speed automatic transmission.  The Infiniti M Hybrid’s exhilarating driving performance also greatly benefits from use of Infiniti’s proven 3.5-liter DOHC 24-valve V6 engine, which paired with the 50 kW electric motor, provides a hybrid system net power of 360 horsepower.
