BMW has confirmed it will unveil a hot 335bhp M340d xDrive version of the seventh-generation 3 Series at this year’s Geneva motor show.
The new variant of the popular executive car will be offered in both the saloon and Touring estate versions, and will benefit from the input of the firm’s M performance. It will use a 3.0-litre six-cylinder turbocharger diesel engine, mated to a 48 volt mild-hybrid starter generator that can add an extra 11bhp. As well as offering 335bhp, the unit produces a maximum of 516lb ft of torque. That compares to the 369bhp and 369lb ft of the six-cylinder petrol-engined M340i.
BMW says the M340d can achieve 0-62mph time of 4.6secs in saloon for, and 4.8secs in Touring trim.
The power is delivered to all four wheels as needed through an eight-speed automatic gearbox. The 340d will also offer specially tuned M sport suspension, brakes and differential as standard, along with a number of exterior design tweaks to aid the model’s aerodynamics.
The mild hybrid system also allows for engine-off coasting and BMW says it allows the diesel powertrain to as much as possible in the most efficient load range, boosting fuel consumption and efficiency. It claims the model can achieve between 49 and 53mpg, with emissions ranging from 139-149g/km for the saloon and 143-153g/km for the Touring version.
The new range-topping diesel model is part of an expanding 3 Series range that BMW will showcase at Geneva, including a new four-wheel-drive 330e Touring.
