Just two years after its highly successful introduction, the INFINITI M receives major upgrades for 2008 that include the first-ever availability of INFINITI’s intelligent ATTESAä E-TS all-wheel drive system on the 4.5-liter V8-powered M45.  The new model, designated M45x, joins the M35x to provide buyers with two choices in all-climate AWD performance.

Other enhancements for 2008 include revised interior and exterior styling and added luxury amenities and technologies, including the production debut of INFINITI’s newest safety technology, the Lane Departure Prevention (LDP) system.  For 2008, previous M Sport models have been replaced by an available Sport Package, which includes unique exterior and interior styling, Rear Active Steer (RAS) and 19-inch wheels and tires.

LDP takes INFINITI’s existing Lane Departure Warning system (currently implemented on the FX and the 2007 M sedan) one step further by utilizing the Vehicle Dynamic Control to apply slight brake pressure to the wheels opposite the side of the lane departure direction to help prevent the M from inadvertently traveling out of its intended lane. 

The INFINITI M’s exterior enhancements for 2008 include revised front and rear fascia, grille, rear fender panels, rear decklid and taillight design, new chrome accents and new 18-inch and 19-inch sport aluminum-alloy wheels.  There are also six new exterior colors (out of an available eight).  There is also greater visual differentiation between the Sport Package-equipped models and non-Sport Package models.

Inside, the new 2008 INFINITI M includes an upgraded INFINITI Hard Drive Navigation System with touch-screen, 9.3GB Music Box hard drive for digital music storage and playback and available XM NavTraffic® (requires active XM® subscription, sold separately), as well as new white and violet instrument panel and interior lighting, standard XMâ Satellite Radio (requires XM® subscription, sold separately) and a revised Stone colored interior.

The M45 continues to offer a 325-horsepower 4.5-liter aluminum-alloy DOHC V8, while the M35 features the award-winning VQ-series 3.5–liter V6, tuned for the M to produce 275 horsepower.  Both engines are mated to a standard 5-speed automatic transmission with performance shifter and manual shift mode with downshift rev matching.

In addition to the advanced navigation system, other available M technology includes Bluetoothâ Hands-free Phone System, INFINITI Information Display with 7-inch LCD screen and easy-to-use controls, INFINITI voice recognition and RearView Monitor.
