M37

This rear-wheel-drive luxury sport sedan appeared for the 2011 model year as the 3.7-liter V6 version of the brand’s midsize executive sedan. It represented the final evolution of the long-running M nameplate before the lineup was rebranded for 2014, when the sedan family moved to the Q70 badge. The car sat at the center of the brand’s performance-luxury strategy: more upscale and technologically advanced than the entry sedans, but still tuned for drivers who wanted a balance of comfort, handling, and long-distance refinement. It was offered in rear-wheel-drive and all-wheel-drive forms, and it shared the model line with a more powerful V8 sibling and, in some markets, a hybrid variant under the broader M series umbrella. The design followed the company’s flowing, athletic sedan styling of the early 2010s, with a roomy cabin, premium materials, and a strong emphasis on driver-assistance and convenience technology. For enthusiasts, this version is notable as the V6 sweet spot in the range: lighter and more approachable than the V8, but still distinctly performance-oriented and positioned as a traditional luxury sedan rather than a crossover or coupe. Its production run ran continuously through the 2013 model year, after which the nameplate was discontinued as part of the brand’s global naming shift.
