new BMW 4 Series Convertible


The new BMW 4 Series Convertible is a sporting yet elegant car, roof raised or lowered. It’s a lower, wider, longer car than the old 3 Series Convertible, with a visibly greater sporting intent.

The BMW 4 Series Convertible has a folding metal roof which can be raised or lowered in just 20 seconds. The optional wind deflector can now be stored behind the seats when not in use, and a new Air Collar system blows warm air around the necks of front seat occupants for open-air driving on cooler days.

At launch the 4 Series Convertible range will consist of two petrol engines and one diesel engine choice, available across five different trim levels.

The BMW 4 Series Convertible goes on sale 8 March 2014, starting at £36,675 OTR for a 420d SE Convertible.

TwinPower technology for performance and efficiency
The state-of-the-art powertrain technology under the skin of the new BMW 4 Series Convertible ensures it delivers an engaging yet efficient driving experience. As is the BMW custom, the engines are in-line and longitudinally mounted up front, sending their power to the rear wheels. All use BMW’s TwinPower Turbo technology, which combines sporty performance characteristics with exceptional efficiency, and are all EU6 compliant.

The diesel engine choice at launch is the new BMW 420d Convertible. It uses the latest-generation four-cylinder diesel engine with composite aluminium crankcase, latest-generation common-rail direct injection technology, a turbocharger with variable turbine geometry and precise solenoid valve injectors, ensuring instantaneous throttle response with extremely low fuel consumption and emissions. With a maximum output of 184hp at 4,000rpm and peak torque reaching 380Nm between 1,750-2,750rpm, it’s no surprise the car can sprint from zero to 62mph in just 8.2 seconds and accelerate up to 146mph if required. Average fuel consumption stands at 55.4mpg and CO2 emissions of 133g/km. With the optional eight-speed Sport automatic gearbox combined fuel consumption falls to 58.9mpg and CO2 emissions to 127g/km.
