BMW kidney with mesh design.
The mesh design of the BMW kidney, which varies depending on the engine, contributes to the dynamic appearance. The basic model has a high-gloss black mesh grille, the Sport Line and M Sport package are made of matt aluminium, each with a kidney frame in chrome. The BMW kidney of the top model M40i is completely in Cerium Grey.

Air Breather.
Together with the air curtain in the front apron, the air breather positioned behind the front wheel arches significantly reduces air turbulence in the wheel arches and targeted channelling of the airflow - thus reducing drag. At the same time, they underline the athletic character of the vehicle as a decorative element.

M Aerodynamics package.
The M Aerodynamic package with M-specific front apron, rear apron and side skirts in body colour and a diffuser insert in Dark Shadow metallic conveys pure dynamics and sportiness. The components not only sharpen the appearance, but also optimize the aerodynamic properties of the vehicle.

Exhaust tailpipes in free-form.
Round high-gloss chrome exhaust tailpipes on the right and left of the rear enhance the vehicle's sporty appearance.

M Sport seats.
The M Sport seats with integrated headrests, deep sitting surface and high side and backrest bolsters offer the driver and front passenger improved support, even in fast turns. In addition, the driver's seat and, depending on the equipment, the front passenger seat can be adjusted to your individual body dimensions thanks to the integrated backrest width adjustment.

M leather steering wheel.
The M leather steering wheel including multifunction and M badge features the sporty three-spoke design. The steering wheel rim in leather 'Walknappa' black with shaped thumb rests conveys a sporty, direct steering feel and thus ensures a dynamic driving experience.
THE DRIVING DYNAMIC OF THE BMW Z4 M40i ROADSTER.

A top athlete conveying pure driving pleasure: The M TwinPower Turbo inline 6-cylinder petrol engine features superior power delivery and the striking characteristic M engine sound. With Double-VANOS, Valvetronic, High-Precision Injection and a TwinScroll turbocharger, it provides excellent output.

Adaptive M suspension.
The 10 millimetre lowered Adaptive M suspension can be electrically adjusted at any time to suit the road and driving conditions. Drivers can also adjust the suspension characteristics via the Driving Experience Control to enable their preferred driving style at the time – from comfortable to extremely athletic with markedly agile handling.

M Sport differential.
The M sport differential optimises traction and driving stability when changing lanes or accelerating out of a bend, when taking bends at high speeds or on different road surfaces. Traction is optimised with the help of an electronically operated device that reduces the difference in revolution speed between the rear wheels.

Steptronic Sport transmission.
The 8-speed Steptronic Sport transmission with Launch Control allows sporty gear changes both automatically and manually via selector lever or paddle shifters – for comfortable gliding or a dynamic driving style. In SPORT or SPORT+ mode and with the gear lever in the left-hand S/M position, the gear shifts are configured for maximum performance.

Variable sport steering.
The Variable sport steering with Servotronic creates a direct and agile steering response and ensures that less physical effort is required to turn the wheel. It reacts to the angle of the steering wheel with varying steering ratios. This improves handling when driving more dynamically and reduces the effort needed to steer when parking and turning.

M Sport brake.
The M Sport brake has four-piston fixed callipers at the front and single-piston floating callipers at the rear in blue with the M designation and features large brake discs to ensure an outstanding braking performance.
