Infiniti Announces Official EPA Estimates for the 2011 M-Series

Infiniti today released official Environmental Protection Agency (EPA) fuel economy estimates for the 2011 Infiniti M performance luxury sedan, showing increases of up to four miles per gallon versus 2010 M models. The new generation M's all-new design includes two new powerplants, a 3.7-liter V6 and 5.6-liter V8, each offering more horsepower and torque than the previous smaller displacement designs.

The 2011 Infiniti M horsepower, torque, fuel economy figures, and increases compared to the previous generation models, are:

MY 2011	M37	M37x	M56	M56x
Horsepower (hp)	330 (+27)	330 (+27)	420 (+95)	420 (+95)
Torque (lb-ft)	270 (+8)	270 (+8)	417 (+81)	417 (+81)
City MPG	18 (+1)	17 (+1)	16	16 (+2)
Highway MPG	26 (+1)	24 (+2)	25 (+4)	23 (+3)

"The all-new 2011 Infiniti M's powertrains offer both increased power and efficiency," said Ben Poore, vice president, Infiniti Business Unit. "Our V6 power is up 9% to 330 horsepower, while V8 power is up almost 30% to 420 horsepower and torque is increased 24% to 417 lb-ft -- while amazingly adding 4 mpg Highway for the M56 and 3 mpg Highway for the all-wheel drive M56x."

Multiple advanced technologies allow the new Infiniti M to provide these increases in power and torque while also improving fuel efficiency across all model offerings. The 3.7-iter V6 and all-new 5.6-liter V8 engine both utilize Continuously Variable Valve Timing Control System (CVTCS) to optimize both intake and exhaust valve timing. Variable Valve Event and Lift (VVEL) technology is also applied to the intake valves on both the V6 and V8 engines to improve performance, emissions and fuel efficiency.

In addition, Direct Injection Gasoline technology is applied to the all-new 5.6-liter V8, providing more precise combustion control to optimize emissions, fuel economy and torque. An electronically controlled 7-speed automatic is applied as the standard transmission on all 2011 M models. As a result of the improved fuel economy figures, the gas guzzler tax previously accessed on the 2010 M45x does not apply to the 2011 M56x.

"It's an impressive feat of engineering to not only gain 95 horsepower and 81 ft-lb of torque while also improving fuel efficiency by up to 4 mpg for the new V8," added Poore. "Most of all, however, we think buyers will be impressed by the smooth, responsive performance of both the new V6 and V8. Power plus efficiency -- that's a great definition of Inspired Performance."
