review of 2010 Infiniti M45 sedan

2010 Infiniti M Press Kit: At a Glance

The Infiniti M mid-size premium performance sedan enters the fifth and last year in its current product cycle in 2010, once again offering buyers a selection of engine choices, driveline configurations, sports or luxury emphasis, and available industry-leading technology to perfectly meet their needs, budgets and desires.

The 2010 Infiniti M – essentially unchanged from the 2009 model when it received a new 303-horsepower 3.5-liter V6 for the M35, a new 7-speed automatic transmission for the M35 RWD model and numerous other enhancements – is offered in M35 and M45 models, each available in rear-wheel drive or with Infiniti’s advanced Intelligent All-Wheel Drive system. The Infiniti M45 and M45x AWD feature a 325-horsepower 4.5-liter V8, while the M35 and M35x AWD come equipped with the 303-horsepower 3.5-liter V6. A special Sport Package (rear-wheel drive models only) adds a higher level of sporty performance and style with an advanced Rear Active Steer system, sport-tuned suspension, 19-inch wheels and tires and unique body treatments.

The 2010 M remains a showcase of Infiniti’s advanced technology, including Intelligent Cruise Control and the Lane Departure Warning (LDW) and Lane Departure Prevention (LDP) systems, an advanced Infiniti Hard Drive Navigation System with touch-screen, 9.3GB Music Box hard drive for digital music storage and playback and available XM NavTraffic® (XM® subscription required, sold separately).
