Why it stands out
The 2021 BMW M3 stands out in the luxury performance sedan segment with its remarkable combination of power, precision, and practicality. It boasts a robust twin-turbocharged 3.0-liter inline-six engine that generates an impressive 473 horsepower in the standard model and up to 503 horsepower in the Competition model. This allows for exhilarating acceleration while maintaining the ability to function as a daily driver. The M3's adaptive performance suspension and multiple driving modes cater to various driving preferences, making it docile for city cruising and ferocious on winding roads or at a racetrack.
The current generation M3 also showcases a modern design that some may find polarizing due to its large front grille, yet it undeniably makes a statement. Inside, the cabin is filled with high-quality materials and advanced technology, including the user-friendly iDrive 7.0 infotainment system, which supports both Apple CarPlay and Android Auto. Additionally, the M3 offers practical features like rear seating for adults and a decent trunk space for a performance sedan. While the M3 certainly has its limitations, such as below-average fuel economy and a firmer ride, it remains a top choice for performance enthusiasts seeking both power and livability.

Overpriced for what you get. Car needs to be $10k-$12k cheaper. It’s being over hyped.

Recently purchased one, and am loving it. Great to have the six-speed manual for the base trim. :)
