2024 BMW M3 CS

Applied to a modern BMW, CS stands for Competition Sport, signaling a high-performance vehicle equally capable on the corkscrew at Laguna Seca and the 405 freeway in Los Angeles. That sums up the new, limited-production 2024 BMW M3 CS, a four-door supersedan with more performance than any M3 to come before it. Based on the M3 Competition xDrive, the new M3 CS adds power, loses weight, and gains tweaks to hone its handling. But this isn't your typical track-focused car, as it has the comfort, technology and practicality necessary to make it something more than a weekends-only racer.

There's nothing quite like the new BMW M3 CS, but the Mercedes-AMG C 63 S E Performance is the worthiest of potential rivals. Better yet, the Benz has a pretty face and a stealthier look. Other alternatives could include the Audi RS 5 Sportback, Mercedes-AMG GT 53 and Porsche Panamera 4, but they don't offer the same simultaneous blend of price, performance and exclusivity as the BMW.

Upgrading to the limited-production M3 CS requires you to spend nearly $35,000 more than the sticker price of an M3 Competition xDrive. What does that pay for? Plenty, starting with carbon fiber-reinforced plastic (CFRP) construction for the hood, rear spoiler, rear diffuser panel and other components. The twin-turbocharged 3.0-liter inline six adds 40 horses for a total of 543 hp (torque remains the same) and boasts racing-derived upgrades to support and withstand hard driving. They include increased maximum turbocharger boost pressure, unique engine mounts, improved drivetrain oiling and cooling, and revised engine management software. BMW also reworks the suspension, enhances the steering, and upgrades the brakes. An active exhaust system featuring an exclusive titanium silencer is the cherry on top.
