The 2011 model year features all-new versions of Infiniti's flagship sedan and large sport utility vehicle. Featuring a shapely sport sedan form born from Infiniti's Essence Concept, the 2011 M sedan arrives as an M37 model with a 330-horsepower V-6 or an M56 propelled by a 420-horsepower 5.6-liter V-8. Rear-wheel drive or an all-wheel drive system can be equipped on the 2011 Infiniti M sedan models. 4-wheel Active Steer and the world's first Blind Spot Intervention system are available on the new Infiniti sedan. Adopting an all-new platform, the 2011 Infiniti QX56 is longer and wider with a more refined presence. A 400-horsepower gasoline direct injected V-8 engine, Around View Monitor and a 13-speaker Bose audio is standard while a new Hydraulic Body Motion Control system is optional. Infiniti also possesses a lower-tier version of their entry-level vehicle for 2011 in the form of the G25 Sedan. Propelled by a 218-horsepower 2.5-liter engine, the G25 Sedan shares many of the standard comforts found with the G37. Featuring tailored sport equipment, the IPL (Infiniti Performance Line) premieres with the G Coupe and G Convertible.
