Power and refinement meet
When you want performance but also crave a level of refinement that’s hard to meet, the 2020 BMW M340 is likely the right vehicle for you. It’s not a true BMW M model, but it gleans a lot from Bimmer’s performance arm, with its inline-six-cylinder turbocharged engine that injects 382 hp and 369 lb-ft of torque into this luxury sedan. This leads to impressive on-road performance, but the M340 also strikes a nice balance with comfort, balancing raucous performance and a comfy ride.

5 reasons to buy the 2020 BMW M340
1. Big power
The 2020 BMW M340 comes standard with a 3.0L inline-six-cylinder turbocharged powerplant that pipes 382 hp and 369 lb-ft of torque into this compact luxury sedan. This power heads through the standard eight-speed automatic transmission and out to all four wheels. All this adds up to a lively 4.1-second zero-to-60 sprint time that’s sure to please you.
2. Comfortable front seats
Up front, the 2020 BMW M340 shines with a set of super-comfortable bucket seats with 14-way power adjustments. Add to that its supple synthetic leather upholstery, and you’ve got the perfect seat for a long daily commute. Plus, with its 17 cu-ft trunk, you have all the trunk room you need for groceries or whatever else you need to haul.
3. All the tech you need
The 2020 BMW M340 lives up to its luxurious nameplate with a wide range of standard tech features you’ll love. Every 2020 3-Series comes equipped with cruise control, ambient lighting, BluetoothⓇ connectivity, Apple CarPlay™ compatibility, and more. The M3450 model builds upon this with HD Radio, SiriusXMⓇ, a digital gauge cluster, and more. It’s ready to please your inner tech lover.
4. Tons of grip
The 2020 BMW M340 needs all the grip it can get to keep its powerful six-cylinder engine in check. It delivers on this with its standard xDrive all-wheel-drive system that distributes power between the front and rear wheels for a quick, slip-free launch. On top of this, the M340’s adaptive suspension with electronic dampers helps it stay glued to the road in corners.
5. Driver-assist tech
The 2020 BMW M340 helps ease your daily commute with a collection of standard driver-assist features, including lane-departure warning and low-speed automatic emergency braking with pedestrian and bicycle detection. If you want even more driver-assist tech, the M340 is happy to oblige. Look out for optional active lane control and adaptive cruise control. If you find it hard to squeeze your car into cramped city parking garages or parallel parking spaces, the 2020 M340 can also help with its available parking-assist feature that handles the heavy lifting for you.
