2020 BMW 3 Series: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2020 BMW 3 Series is the arrival of the 382-hp M340i and M340i xDrive performance sedans. This is otherwise a light second-year update for the redesigned G20 sedan, with more technology becoming standard.
About the 2020 BMW 3 Series
7th generation (G20), second model year for the redesigned sedan; first year for the M340i and M340i xDrive trims.
BMW positions the 3 Series as its core compact sports sedan: a daily driver that is meant to feel sharp and driver-focused without giving up comfort, space, or modern tech. In BMW’s own framing it is the brand’s iconic sports sedan, sold on balanced handling, quick turbo engines, supportive seats, and a cabin that mixes luxury with a purposeful, road-first feel. That combination is what separates it from softer compact luxury sedans.
The 330i remains the balanced everyday choice, pairing a 255-hp turbo four-cylinder engine with an 8.8-inch touchscreen, navigation, power sport seats, and a moonroof. The new M340i models turn up the performance with a 382-hp turbocharged six-cylinder engine, stronger brakes, a sport-tuned suspension, an electronic locking rear differential, and larger digital displays. The xDrive versions add all-wheel drive for better traction.

“The technology upgrades on this vehicle are impressive while not sacrificing style or performance (which was actually improved)”
“This is an excellent car. It looks great, is fun, sporty, reliable and drives well. I chose this over the 5 series because I didn't think I needed extra room in the backseat. But after having it a few months I wish I had chosen the 5 series it is just roomier and a little more luxurious.”
