The latest-generation BMW TwinPower Turbo 2.0-litre 4-cylinder petrol engine guarantees maximum driving pleasure. Notable for its agile power delivery and outstanding responsiveness even at low engine speeds, it’s also exceptionally fuel efficient and low in CO2 emissions.

8-speed steptronic transmission

8-speed sport automatic transmission.


The 8-speed sport automatic transmission ensures maximum levels of dynamics, efficiency and ride comfort. Short shifting times improve the acceleration values while the fine spacing of the eight gears permits barely noticeable gear changing. At the same time, the engine is maintained at the ideal level of revs for optimum power development while noise level is reduced. The eighth gear reduces the revolutions of the engine at high speeds and hence fuel consumption and CO2 emissions.

Sporty driving characteristics.


Even in the most beautiful weather, the BMW 4 Series Convertible is able to further enhance your good spirits. With Driving Experience Control. This is because the SPORT mode or SPORT+ mode activates a stiffer damper setting and this ideal for a dynamic driving style. Especially so in combination with the Adaptive M suspension and the optional variable sport steering with Servotronic. Both components produce even more comfortable handling.

An ideal 50:50 axle load distribution ensures great directional stability, agile handling and a precise steering response. At the same time, a lower centre of gravity and shorter overhangs improve driving characteristics.

​By electronically regulating the shock absorbers, Adaptive M suspension automatically tunes the vehicle to suit all driving conditions. Suspension characteristics can also be adjusted via the Drive Experience Control to enable the preferred driving style - from comfortable to athletic with markedly agile handling.

Variable sport steering with Servotronic enables a direct and agile driving style with less physical effort when steering. Through reacting to the angle of the steering wheel independently from the current speed, the steering movement required at large angles is reduced. The selectable SPORT+ mode is an additional feature of this package.


Less fuel consumption, more driving pleasure: That is BMW Efficient Dynamics. It covers an array of different technologies that affect the drive system, energy management and the vehicle concept. The result is lower fuel consumption and fewer CO2 emissions with more dynamics and driving fun at the same time. A standard feature in every BMW – and of course in the BMW 4 Series Convertible as well.



Fuel consumption and CO2 emissions.

Consumption data is determined in accordance to the ECE driving cycle and depend on the wheel and tyre sizes selected.

The figures do not refer to an individual vehicle and do not constitute part of the offering; they are intended solely as a basis for comparison of the different vehicle types. CO2 emissions occurring during the production and provision of the fuel or other energy sources are disregarded when determining the CO2 emissions in accordance with Directive 1999/94/EC.
