What is the BMW 3 Series M340d

Leading the way in the premium executive class, the BMW 3 Series M340d builds on the base 3 Series model and provides exceptional performance and advanced technology. Released in spring 2020, it comes in four-door saloon and Touring (estate) guises. The M340d brought the brand’s sporty M feel to a diesel-powered 3 Series for the very first time, rivalling other premium performance vehicles like the Audi RS4 and Mercedes-Benz C-Class AMG.

The M340d is designed to deliver a thrilling experience while keeping fuel consumption low. To that end, the powertrain includes 48-volt mild hybrid technology, which boosts power during acceleration and increases efficiency during cruising. The car’s sporty nature is characterised by 18-inch M light-alloy wheels, blue painted brake callipers and M badging. The saloon also features a body-coloured M rear spoiler.

BMW 3 Series M340d history

The BMW 3 Series first graced UK roads in 1975. Such has been its success over the decades that the model entered its seventh generation in 2018 and remains a popular option for families and business users alike. In 2019 the high-performance M340i petrol variant was added to this Mk7 lineup, providing buyers with the same practicality but a more exciting driving experience.

The M340d variant launched at the Geneva Motor Show in 2020, arriving at showrooms later that year. It offered a more frugal alternative to the petrol M340i while delivering the same breathtaking performance that motorists expect from M-badged vehicles. Equipped with a 3.0-litre six-cylinder diesel engine, enhanced by 48-volt mild hybrid technology, it produces 335bhp and 700Nm of torque. That takes the saloon from 0–62mph in 4.6 seconds and the estate from 0–62mph in 4.8 seconds.

Power is controlled via an eight-speed automatic gearbox and is delivered to all four wheels thanks to BMW’s xDrive system. Specially tuned M Sport suspension and brakes also provide a sporty ride and improve stopping capability.

In 2022, the Mk7 3 Series was given a facelift and the technology enhancements extended to the M340d. In place of the variant’s original 8.8-inch ‘Control Display’ came a ‘Curved Display’ interface, which combines a 12.3-inch ‘floating’ instrument cluster and a 14.9-inch touchscreen for infotainment.

Where does the BMW 3 Series M340d sit in the range?

The BMW M340d tops the Mk7 BMW 3 Series range alongside its M340i petrol counterpart. Both variants are set apart from the rest of the lineup by their sporty exterior details as well as expertly tuned suspension, brakes and steering. The combination of athletic styling and outstanding performance ensure this is a true driver’s car that effortlessly captures attention.

What features and equipment does the BMW 3 Series M340d have?

As a performance car, the BMW 3 Series M340d adopts a sporty aesthetic that immediately sets it apart from the rest of the range. The 18-inch M light-alloy wheels have blue painted brake callipers and both body styles have styling elements that improve cooling and aerodynamics. Further touches such as the individual high-gloss Shadowline trim and Cerium Grey metallic finishes on the mirror caps and grille mesh ensure an exclusive feel.

To aid performance, the M340d is equipped with the BMW xDrive system, which has a rear-biased setup to deliver the sporty feel of M performance while offering maximum stability and traction in challenging conditions. The driving experience can be further tailored with the Driving Experience Control switch, which enables you to select ECO PRO mode for optimum efficiency, COMFORT for a balance between performance and efficiency, or SPORT and SPORT+ for optimal driving dynamics.

In addition to its exterior upgrades, the M340d boasts blue and pearl-effect chrome accents, sports seats and a leather multifunction steering wheel. The three-zone automatic climate control offers separate controls for the driver, front passenger, and rear compartment, enabling every occupant to travel at their preferred temperature. Meanwhile, ambient lighting provides soft illumination in a hue of your choice.

The 3 Series M340d comes with an impressive suite of technologies as standard. Park Distance Control, for example, makes parking and manoeuvres safer with front and rear sensors. For your infotainment needs there is the BMW Live Cockpit Plus system, which provides navigation, as well as the Connected Package Plus, which features real-time traffic information, remote and concierge services and Apple CarPlay integration.
