Love ’em or hate ’em (and The Sleuth is in the thumbs-up camp) both these performance-oriented 2021 Bimmers will sport enlarged (and seriously expressive) kidney-shaped grilles when they go on sale next spring. Each model comes with a twin-turbocharged six-cylinder engine that produces 473 horsepower in standard livery, or 503 horsepower in the more potent Competition versions. Both manual and automatic transmissions will be available.
The M3 and M4 have busy faces, which The Sleuth happens to like. The highest performing models make more than 500 horsepower from their six-cylinder engines. PHOTO: BMW
