The  BMW M3 has garnered quite a reputation in the sports car world. For almost 40  years, the M3 name has been synonymous with power and performance. The  performance variant of the 3 Series consistently dominates the luxury sport  sedan segment. Unlike most of its competition, the M3 leans more toward  performance and less toward comfort. But it still offers plenty of luxury. An  enthusiast-preferred six-speed manual transmission routes 473 horsepower to the  rear wheels in the base M3. But if you want an automatic transmission, go for  the 503-hp M3 Competition, which is available in rear- or all-wheel drive. For 2024,  there's a new model for those looking for the most the M3 has to offer. ;The  M3 CS is a new limited-production, track-focused version of the M3. It's the  most powerful M3, producing 543 hp, and the lightest thanks to lightweight  components that save 75 pounds. It shares many upgrades with its fellow track  monster, the two-door M4 CSL, but keeps its rear seats and adds all-wheel drive  for improved acceleration. A titanium muffler, upgraded brakes and lighter  forged wheels with sticky high-performance tires (superior Michelin Pilot Sport  Cup 2 tires are a no-cost option) are just some of the go-fast parts BMW threw  at the M3 CS. The highly capable sedan also boasts an adaptive suspension,  stability control and steering that's been configured for track use. ;As  impressive as the M3 is, its styling and somewhat stiff ride aren't for  everyone. Also, the luxury sport sedan segment is packed with many talented  alternatives, including the all-new Mercedes-Benz AMG C 63 S E-Performance  plug-in hybrid, the stylish and comfortable Audi RS 5 and the Italian option:  the superb Alfa Romeo Giulia Quadrifoglio. The Cadillac CT4-V Blackwing is  another often overlooked but similarly worthy rival.
