Infiniti made a last minute decision to show its products at the Chicago Auto Show and so it took some searching to find the brands new 2011 M model tucked away in a back corner. But it was worth the hunt. Infiniti actually showed the car to us at a private event during the LA Auto Show, but the car’s Chicago Auto Show debut will be its first public appearance.

For 2011 the M will be offered as both an M37 and M56 model, each of which will be offered in either RWD or AWD. Like the G37, the M37 is powered by a 3.7-liter V6 engine with 270 ft-lbs of torque. As for the M56, it gets a massive 5.6-liter mill with an impressive 420-hp and 417 ft-lbs of torque. In total, the new top-level M gets 95-hp and 81 ft-lbs of torque over its predecessor, the M45.

Those looking for even more sport can opt for a Sport Package (RWD only), that comes with 20-inch wheels, a sport tuned suspension, larger brake rotors with 4-piston front calipers and two-piston rears, 4-Wheel Active Steer (4WAS) steering, as well as a sport steering wheel, pedals and shift knob. Specific to the Sport Package are special double-piston shocks that deliver a ride that is both comfortable and stable. There’s even a unique front fascia.

Both engines come with Infiniti’s 7-speed sport automatic transmission, allowing the M56 to get even better fuel economy than the old M45.

As for the car’s size, it is larger than the outgoing M, measuring roughly half an inch longer at 194.7 inches, 2-inches wider at 72.6 inches. It is also roughly half an inch lower at 59.1 inches to help keep the car’s center of gravity low.

One of the most exciting features on the new M is Infiniti Drive that allows a driver to choose between four settings of throttle pressure and transmission shift points. There’s also an Active Tracing Control system that adjusts engine power and braking at all four wheels for optimum performance. Safety items include Blind Spot Warning and Blind Spot Intervention that helps bring the car back towards the center of the lane. There’s also an Eco Pedal feature that, when selected, uses green and yellow lights on the instrument panel to give the driver feedback on his or her driving, while also giving feedback through the gas pedal, pushing back to alert the driver when they are operating the vehicle inefficiently. Infiniti says that in testing this simple method has lead to improved fuel economy of five to 10 percent.

While the media was given a sneak peak at the all-new 2011 Infiniti  M37 and M56 models at a private event a few months back, the cars will be on public display for the first time at the Chicago Auto Show. After dropping out of most auto shows last year, skipping LA and then Detroit at the start of 2010, Infiniti and parent company Nissan made an 11th hour decision to attend the Chicago show.

For 2011 the M will be offered as both an M37 and M56, with both models being either RWD or AWD. Like the G37, the M37 is powered by a 3.7-liter V6 engine with 270 ft-lbs of torque.

Infiniti has just unveiled the latest generation of its M cars at the swanky SLS Hotel in Beverly Hills, CA. The M will be offered as both an M37 and M56, with both models being either RWD or AWD. Like the G37, the M37 is powered by a 3.7-liter V6 engine with 270 ft-lbs of torque. As for the M56, it gets a massive 5.6-liter mill with an impressive 420-hp and 417 ft-lbs of torque.

Official release after the jump:

With Infiniti’s parent company (Nissan) have made it clear that it would not display at the LA Auto Show due to budget concerns, the automaker is preparing to use the event to its advantage by showing the all new 2011 Infiniti M37 and M56 at a private event the evening prior to the show.

Infiniti has already teased us with a few CGI images, but not the real thing. What we do know is that, as the names suggest, the M37 will be powered by a 3.7-liter V6, much like in the G37, with an expected 330-hp. And as for the M56, well, it will boast a massive 5.6-liter V8 with more than 400-hp!

AutoGuide will be on hand with live coverage of the Infiniti unveilings starting December 1st.

Nissan has chosen the Tokyo Auto Show to debut the next generation of the company’s top-level Fuga luxury sedan. Sold in North America as the Infinti M, it’s not clear if Nissan plans to offer the same 3.7-liter V6 (M37) and 5.6-liter V8 (M56) engine choices. Nissan will, however, deliver a hybrid model, similar to the M35 Hybrid that the company announced yesterday. Engineered comletely in-house, this new hybrid model promises increased performance with increased fuel economy and will use a lithium-ion battery pack, combined with an electric motor and Nissans 3.5-liter V6 engine.

In a sign of what is to come with the new Infiniti M37/M56, Nissan has said the new Fuga will contain several “worlds first” technological innovations.

As promised Infiniti gave a “virtual” preview of the upcoming 2011 M today at the Pebble Beach Concours d’Elegance. Using state-of-the-art 3D video mapping technology, an image of the new M was projected onto a molded styrofoam shape, revealing the third-generation of the sedan that is both sporting and luxurious.

The new design is a big step for the M as it gets design cues from the Essence Concept that was launched at this year’s Geneva Auto Show.

Infiniti is keeping tight-lipped about most of the details, but we do know that both an M37 and M56 model will be offered. The M37 will use the 3.7-liter V6 as found in the current G37 and make roughly 330hp. As for the M56, as the name suggests it will get a 5.6-liter V8 and deliver in excess of 400hp!

One technology highlight of the car is a new blind spot alert system that will not only detect if there is a vehicle in the next lane over, but it will also then help bring the M back into its lane.

Both models will be available starting in the Spring of 2010 as 2011 models in 32 markets around the world.
