UPDATE: We've driven the new BMW M340i on the track! Driving impressions are included in our 2019 BMW 3 Series First Review.
  • First M Performance model based on 3 Series
  • Rear-drive and xDrive all-wheel drive variants offered
  • Inline six makes 382 horsepower, 369 lb-ft of torque
  • Estimated 4.2 seconds 0-60 mph acceleration
  • Pricing estimated to start in the mid- to upper $50,000 range


It’s not the return just yet of the legendary M3 on the all-new 3 Series, but the introduction of the 2020 BMW M340i marks the first time that an M Performance variant has been offered on this iconic compact sport sedan. The M Performance models act as a bridge between the standard cars and the all-out performance M versions.

The new performance option is offered in two flavors, a rear-drive M340i and the all-wheel drive M340i xDrive. The 5-passenger sedans are based on the all-new BMW 3 Series that made its global debut at the Paris Motor Show earlier this year.

The M340i is powered by a twin turbo inline 6-cyinder engine, which makes 382 horsepower and 369 lb-ft of torque mated to an 8-speed Steptronic automatic transmission. BMW says the output is good for an estimated 0-60 mph run of 4.2 seconds.

M Sport suspension

The BMW M340i is equipped with an M Sport suspension as standard equipment with the availability of an optional M Adaptive setup featuring electronically controlled shock absorbers.

The M Sport suspension delivers a tauter ride thanks to recalibrated front and rear shocks that offer additional hydraulic force up front and compression limited components in the rear that help reduce body pitch over uneven surfaces.

The M Adaptive suspension delivers damping force to corner thanks to continuously adjustable valving. BMW says it’s the sportiest and most comfortable chassis offered on the new 3 Series.

An added benefit is that the new control algorithm takes into consideration vehicle loading to adjust the shocks.

Other bits from the M Sport parts bin include an electronically controlled rear locking differential, more powerful brakes and specially tuned steering.

Aggressive looks

Based on the sleek shape of the new 3 Series, BMW M340i and M340i xDrive Sedans have a more aggressive look thanks to new detailing on the front. The traditional twin kidney grille has mesh inserts framed by a single surround and has wide bars that connect to the LED headlights. The hood features four contour lines flowing into the grill. This panel’s leading edge sits flush with the upper edge of the headlights and kidney grill. Below, the front bumper has additional inlets and contouring emphasizing the width of the car. Other details like the exterior mirrors, air intakes, the grille surround, tailpipes and badging are all finished in Cerium Gray Metallic.

Inside, the standard sports seats feature a combination of Sensatec/Alcantera upholstery that is exclusive to M Performance vehicles. The grippy material and side bolstering provide lateral support and the seats themselves offer a greater range of adjustment. Premium leather with contrast stitching and piping is an available option. The interior is also fitted with an anthracite-colored roof liner for BMW Individual, M leather steering with shift paddles and aluminum interior accents.


While pricing has yet to be announced not only for the M340i but also the all-new BMW 3 Series, we can expect a premium over the current 3 Series pricing which ranges from $48,950 for the 2018 340i up to $50,950 for the 340i xDrive. The 2019 M240i and M240i xDrive are priced at $45,800 and $47,800 respectively.
