Based on the perennially popular BMW 3 Series sedan, the M3 is a four-door sedan, tweaked for more performance and power than the longstanding fan favorite. Similarly, the BMW M4 is based on the eye-catching 4 Series models, which means it comes in the same, familiar options of either a two-door coupe or two-door convertible, but with the more-powerful engine upgrade under the hood.
Both cars come with a standard 473 horsepower and 406 pound-feet of torque, thanks to their base engine, a turbocharged 3.0-liter inline six-cylinder. Drivers who crave a little more power can opt for the higher-level Competition models, which get a spiced-up version of the same powertrain and produce 503 horsepower and 479 pound-feet of torque.
Regardless of which style, model, or powertrain you go for, you can expect both the M3 and M4 models to offer the signature BMW traits we know and love, with a priority on luxury and emphasis on unbeatable quality.
