The BMW M3 has long been the benchmark for sports sedans, and the 2025 model year continues this legacy. Building upon the already impressive foundation of the BMW 3 Series, the M3 elevates performance to exhilarating levels, cementing its place as a top contender in the Best Sedan Sports Car category. It manages to blend track-ready capabilities with the everyday usability that makes the regular 3 Series so appealing.

At the heart of the 2025 M3’s transformation is its potent engine. The 3.0-liter twin-turbocharged inline-six engine delivers a robust 473 horsepower in its standard configuration. This represents a significant 91-hp increase over the already sporty M340i. Power is channeled to the rear wheels through a standard six-speed manual transmission, a rarity in today’s performance car market and a delight for driving purists. For those preferring automatic transmissions or even greater power, the M3 Competition variant is available. The Competition model boosts output to 503 horsepower and replaces the manual with a quick-shifting eight-speed automatic transmission. Furthermore, all-wheel drive is offered as an option on the M3 Competition, pushing the horsepower figure even higher to 523 hp.
However, the M3’s prowess extends far beyond just horsepower figures. BMW’s engineers have thoroughly reworked the suspension, incorporating adaptive dampers that strike an ideal balance between road comfort and track precision. Upgraded brakes provide confident stopping power, while larger wheels fitted with performance tires enhance grip and handling. These enhancements transform the 3 Series into a true performance machine, equally adept at setting fast lap times and cruising comfortably on the highway. A suite of selectable drive modes allows drivers to tailor the M3’s dynamics to various conditions, offering a customizable driving experience.

Inside, the M3’s cabin retains the strengths of the standard 3 Series sedan, offering generous passenger space both in the front and rear. The design is both functional and stylish, creating a premium and driver-centric environment. The front seats are more aggressively bolstered than those in the standard 3 Series, providing enhanced support during spirited driving without sacrificing everyday comfort. Subtle “M” badging and aluminum trim accents subtly hint at the car’s performance pedigree. New for 2025 is a flat-bottomed three-spoke steering wheel and an upgrade to BMW’s latest infotainment software. A large 14.9-inch touchscreen display serves as the central hub, complemented by a customizable 12.3-inch digital instrument panel that provides essential vehicle information directly to the driver.
While the BMW M3 pioneered the sports sedan segment, it faces stiff competition today. The Alfa Romeo Giulia Quadrifoglio offers comparable performance with distinctive Italian styling. The Mercedes-AMG C63 is another formidable German rival, boasting immense power and track-focused engineering. For an American alternative, the Cadillac CT4-V provides impressive performance at a more accessible price point.
Despite the strong competition, the 2025 BMW M3 remains a compelling choice for those seeking the best sedan sports car. Its blend of powerful performance, refined handling, and everyday practicality continues to set the standard in its class. Whether you prioritize track days or daily driving enjoyment, the M3 delivers an exceptional driving experience that few sedans can match.
