2013 Infiniti M Review

Rivals offer better fuel economy or a more comfortable ride, but test drivers say that the 2013 Infiniti M stands out with athletic performance and user-friendly tech features.

The Infiniti M is available with a choice of two engines and test drivers agree that while the base V6 offers ample power, the optional V8 makes the M exceptionally quick. A seven-speed automatic transmission is standard, and auto writers say that it offers seamless shifts around town, as well as quick, sporty gear changes in manual mode. The EPA reports that the 2013 Infiniti M gets up to 18/26 mpg city/highway, which is a bit low for a V6-powered luxury large car. Most automotive critics appreciate the Infiniti M’s athletic handling, noting that it corners and steers with precision. However, one reviewer says that some of the M’s German competitors provide a more enjoyable driving experience. Additionally, some test drivers note that the M’s ride can be a bit harsh, particularly when optioned with larger wheels and a sport-tuned suspension.

Reviewers say that the 2013 Infiniti M has an attractively-designed cabin that’s built with premium materials. Although one reviewer writes that taller back-seat passengers may want more headroom, most critics think that the M offers a spacious cabin with comfortable front seats. Reviewers also like the Infiniti M’s intuitive tech features, which include audio, climate and navigation systems that are straightforward and easy to use. However, one test driver notes that the infotainment system’s controller isn’t ideally placed. The 2013 M comes standard with a moonroof, a rearview camera and a six-speaker stereo with Bluetooth, satellite radio and a USB port. A number of option packages are available, which add features like a Bose stereo, rear parking sensors, navigation, a power rear sunshade, adaptive cruise control and forward collision and lane departure warning systems.

  • "In terms of providing real sport and real luxury, the 2013 Infiniti M stands as the real deal." -- Edmunds 
  • "The 2013 Infiniti M competes on price with the BMW 5 Series and the Mercedes-Benz E-Class but the Infiniti offers more standard features." -- Kelley Blue Book 
  • "For those with the income to afford such a luxury car, the M37 will hit all the right buttons especially for those who are seeking something other than a comparable BMW or Mercedes in their driveway. Yet overall refinement falls just a few ticks short of the M's German rivals and I like the way Germans address the mix of driving fun and luxury." -- MarketWatch
  • "These sedans are easily the most comfortable and luxurious cars Infiniti has ever produced. In fact that finely tuned blend of sportiness and luxury in these new M sedans could steal quite a bit of business from Infiniti's German rivals." -- Popular Mechanics (2011)

Other Cars to Consider

The Mercedes-Benz E350 may not be as performance-oriented as the M37, but reviewers say that the E350 offers composed handling, a comfortable ride and an ultra-luxurious interior that’s built with premium materials. The E350 also earns great safety scores and gets slightly better fuel economy than the M37.

Test drivers say that the Lexus GS 350 offers athletic handling and a comfortable ride, as well as an interior that’s attractive and upscale. The GS 350 also outshines the M37 with better fuel economy and an exceptional reliability rating.
