With its powerful V8 and nondescript styling, the previous M45 was a sleeper. Unfortunately, the styling was a little too drab for American tastes. The new M should easily avoid this problem. With its aggressive styling and a V6 model, the M broadens its appeal. The second generation M rides on a longer and updated version of the RWD FM platform from the G35 and FX35/45. The range includes the 275hp M35, M35 Sport and M35 AWD V6 models and the 340hp M45 and M45 Sport 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.
