BMW 4 Series Convertible
The new BMW 4 Series Convertible is here, and the 420d SE Convertible has a combined economy figure of 55.4 mpg, or 58.9mpg with the optional eight-speed Sport automatic gearbox, along with 133 g/km CO2 emissions, or 127g/km with the auto.
The 4 Series Convertible has a folding metal roof which can be raised or lowered in just 20 seconds and at speeds of up to 8mph. 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. All powertrains use BMW’s TwinPower Turbo technology, which combines performance with efficiency, and are all EU6 compliant.
The new BMW 435i Convertible heads up the range with its straight-six 3.0-litre petrol engine. It can sprint from zero to 62mph in just 5.6 seconds, with an electronically limited top speed of 155mph. The average fuel consumption is from 34.9mpg and CO 2 emissions from 190g/km. The car is even more economical when fitted with the optional eight-speed Sport automatic gearbox, achieving a combined fuel consumption of just 37.7mpg, while CO 2 emissions are down to 176g/km.
The 428i Convertible has a 2.0-litre four-cylinder turbocharged engine, with 245hp. This equates to a zero to 62mph dash in 6.4 seconds and an electronically limited top speed of 155mph, while the average fuel consumption stands at just 41.5mpg, and CO2 emissions are only 159g/km. With the optional eight-speed Sport automatic gearbox, combined fuel consumption is 42.8mpg and CO2 emissions are 154g/km.
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 and 380Nm peak torque, the car can sprint from zero to 62mph in just 8.2 seconds and accelerate up to 146mph. Average fuel consumption stands at 55.4mpg and CO 2 emissions of 133g/km. With the optional eight-speed Sport automatic gearbox combined fuel consumption falls to 58.9mpg and CO 2 emissions to 127g/km.
A six-speed manual gearbox is standard in the 4 Series Convertible. Alternatively, customers can specify an eight-speed automatic gearbox that adjusts to a wide range of driving styles and offers manual gear changes via paddles on the steering wheel.
Efficient petrol and diesel engines, with lightweight and innovative transmissions with reduced frictional losses, contribute to fuel savings and low emissions. Other features that improve overall economy include lightweight construction, intelligent aerodynamics, on-demand power for ancillary units and an innovative Proactive Driving Assistant that tells the driver when to ease off the accelerator upon approaching corners and speed-restricted zones.
The range is characterised by a marked increase in the standard equipment level offered, despite the minimal increase in price.
The BMW 4 Series Convertible goes on sale 8 March 2014, starting at £36,675 for a 420d SE Convertible.
