2021 BMW 3 Series vs 2021 Mercedes-Benz C-Class

Early generations of the BMW 3 Series redefined what a luxury car could be, justifying their prestige badge with sporty driving dynamics and impeccable engineering. BMW changed the luxury-car paradigm, proving that nimble sports sedans could be just as desirable as wood-encrusted land yachts.

The 3 Series spawned a number of imitators, including the Audi A4, Mercedes-Benz C-Class, and Lexus IS. Those sedans, along with the Acura TLX, Alfa Romeo Giulia, Cadillac CT4, and Infiniti Q50 (which wear more recently-introduced nameplates) still form the 3 Series’ competitive set, but the car itself has changed.

Introduced for the 2019 model year, the current-generation 3 Series (codenamed G20) feels more like a traditional luxury sedan, with a greater emphasis on comfort and convenience than previous generations. The manual transmission is gone, as are the wagon and 3 Series GT hatchback body styles. The 3 Series coupe and convertible were re-badged as the 4 Series beginning with the 2014 model year.

The biggest change for the 2021 BMW 3 Series is the addition of the 330e plug-in hybrid model to the lineup, so that’s what we test drove for this review. BMW also offers 330i and M340i versions, and there’s an M3 performance model on the way.
