2011 Infiniti M37 and M56 official EPA estimates

Article by Christian Andrei, on August 26, 2010

Nissan's 2011 Infiniti M sedan has Environmental Protection Agency (EPA) fuel economy estimates that indicate an increase of up to four miles per gallon as compared to the 2010 models. Infiniti, Nissan's luxury division, revealed that the 2011 Infiniti M range will go on sale starting March 18. The 2011 Infiniti M will be offered in two different configurations: V8, which will be designated Infiniti M56; and V6, which will be designated Infiniti M37.

In a release, Ben Poore, vice president, Infiniti Business Unit, said that the all-new 2011 Infiniti M's powertrains "offer both increased power and efficiency.

"Poore added that the 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. He also emphasized that this added 4 mpg Highway for the M56 and 3 mpg Highway for the all-wheel drive M56x.

For better performance, the 3.7-liter V6 and all-new 5.6-liter V8 engine both use CVTCS and VVEL technology. Furthermore, Direct Injection Gasoline technology is applied to the all-new 5.6-liter V8. All 2011 models also get an electronically controlled 7-speed automatic as the standard transmission. Poore stated that a 95hp gain and 81 ft-lb of torque while also improving fuel efficiency by up to 4 mpg for the new V8 is an "impressive feat of engineering."

The V6 and the V8 are also said to boast a smooth and responsive performance's a remarkable blend of power and efficiency.

Ben Poore, vice president at Infiniti Business Unit, remarked that the powertrains for the 2011 Infiniti M now boast of more power and better efficiency. He noted that the 3.7-liter V6 engine produces nine percent more power to 330 hp while its 5.6-liter V8 has almost 30-percent more power to 420 hp and 24-percent more torque to 417 lb-ft.

Despite the increase in power, Poore said, the Infiniti M56 is now 4 mpg (highway) more efficient, while all-wheel drive M56x is now 3 mpg (highway) more economical. To make this happen –more power and torque yet less fuel consumption, Infiniti employed several advanced technologies on the new Infiniti M engines like Continuously Variable Valve Timing Control System (CVTCS), which optimizes both intake and exhaust valve timing.

Both the V6 and V8 engines come with Variable Valve Event and Lift (VVEL) that helps improve their performance, emissions and fuel efficiency. Specifically, the all-new 5.6-liter V8 comes with Direct Injection Gasoline technology, which employs more precise combustion control to optimize its fuel economy, torque and emissions.

All 2011 Infiniti M models come with an electronically controlled 7-speed automatic transmission as standard. Interestingly, the 2011 Infiniti M56x is now free from the so-called gas guzzler tax that was imposed on the 2010 M45x, thanks to better fuel economy numbers.

Poore described as “impressive” the feat of making the V8 gain 95 hp and 81 ft-lb of torque while improving mileage by up to 4 mpg. He added that customers will be impressed by the smooth responsive performance of both engines.

Infiniti Announces Official EPA Mileage Estimates for All-New 2011 Infiniti M37 and M56 Performance Luxury Sedans

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 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-liter 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."

The all-new 2011 Infiniti M is scheduled to go on sale at Infiniti retailers nationwide beginning March 18, 2011.
