Infiniti has applied the same formula of its FX45 SUV to its flagship sedan, the 2008 Infiniti M45 receives an extra shot of power from a 4.5-liter, 325 hp V-8. New this year, V-8 power is available in RWD or AWD which should compare well with Volvo S80 AWD and Audi's Quattro models. A 5-speed automatic with rev-matching manual shift paddles help deliver EPA estimated 16/21 mpg/hwy. Styling has been revised inside and out, and the sedan shares its taut suspension, numerous safety and technology options, and bang for the buck as its M35 sibling but with extra go under your right foot.Read more Read less
For 2008, a new all-wheel-drive M45x model joins the existing Infiniti M35x all-wheel drive model and the rear-wheel drive M35 and M45 models. A newly available lane departure prevention system helps improve safety. Previous M35 and M45 Sport models have been replaced by an optional Sport Package, which brings styling differences, rear active steer, and 19-inch sport wheels and tires. The M also gets a number of enhancements, such as a revised front and rear appearance, reshaped fenders and decklid, redesigned fog lamps, new chrome trim, and new 18- and 19-inch wheel designs. Six of the eight available exterior colors are new. Inside, the changes are equally pronounced, with new "Fine Vision" electroluminescent gauges, a revised center console, a new full gray interior color, new door trim, and new wood trim and aluminum texturing throughout. Instrument panel lighting is now in white and violet hues, and the available hard drive navigation system, with integrated digital music system, has been upgraded with XM NavTraffic live traffic-information.
World-debut technology features; sharp handling; great ride; strong, smooth powertrains.
Part sport sedan and part posh luxury car, the 2008 Infiniti M35 and M45 stand out from the market due to their available onboard for the technology, including a sophisticated rear-wheel steering system and a lane-departure system that actually nudges the vehicle back into its lane. Both models also stand out for having a quiet interior, a well-controlled ride, and strong, smooth powertrains.
