Too often in the shadow of the G35, Infiniti's M warrants our attention. Although it is true that its look is rather discreet, it hides a very rigid platform, a performance that rivals the best Germany has to offer, and very reliable mechanics. The M35 and M35 X are powered by the unavoidable 3.5-litre V6, while the M45 gets a 325 horsepower V8 engine, a more luxurious interior, and a comprehensive list of equipment.
