With its powerful V8 and nondescript styling, the first generation M45 was a sleeper. Unfortunately, the styling was a little too drab for American tastes. The second generation of the M sedan features aggressive styling and a V6 model, broadening its appeal. The model range includes the 275hp M35, M35 Sport and M35 AWD V6 models and the 340hp M45, M45 Sport and M45 AWD V8 models. All are equipped with a five-speed automatic and stability control. The M features many common luxury touches but also offers rare optional features like a backup camera and a lane-departure system. Sport models feature a motor-actuated active steering system that changes the rear suspension geometry to augment handling. Infiniti's M is well-styled, well-powered and well-equipped to do battle in a robust market segment.

What Changed:

The M is updated for 2008 with revised styling on the front and rear fascias. A new grille and standard HID xenon headlights adorn the front. New fenders, decklid and revised taillights are found in the rear. Sport models will wear distinct bumpers and side sill extensions. The interior is updated with new aluminum and wood trim. The instrumentation features new white lighting with violet accents. AWD will be available for the first time with the V8 in the new M45x model. Six new colors and new wheel designs round out the changes.
