2026 BMW M4 COMPETITION CONVERTIBLE M xDRIVE (G83) — GERMAN MARKET SPECIFICATION

Engine and Drivetrain

The M4 Competition Convertible is powered by the S58 M TwinPower Turbo petrol engine, a 2,993 cc twin-turbocharged inline-six producing 390 kW (530 PS / 523 bhp) and 650 Nm of torque. Drive is through an eight-speed M Steptronic automatic transmission with Drivelogic and the rear-biased M xDrive all-wheel-drive system, which offers 4WD, 4WD Sport and a pure rear-drive 2WD mode, with an electronically controlled Active M Differential across the rear axle.

Roof and Body

The G83 uses an electrically operated fabric soft top in place of the coupé’s carbon fibre roof panel. The roof operates at road speeds up to 50 km/h and stows under a body-coloured cover; luggage capacity is 385 litres with the roof raised and 300 litres with it stowed. Additional body reinforcement and a rollover protection system compensate for the removed roof structure, which accounts for the convertible’s higher kerb weight over the coupé.

Chassis, Steering and Brakes

Adaptive M suspension with electronically controlled dampers is fitted to a double-joint spring-strut front axle and five-link rear axle with M-specific kinematics. Steering is electromechanical M Servotronic with a variable ratio, and braking is by M Compound brakes with red-painted callipers, internally ventilated and drilled at both axles.

Dimensions and Capacities

Overall length is 4,801 mm on a 2,857 mm wheelbase, with a width of 1,887 mm excluding mirrors and a height of 1,399 mm. Kerb weight to the DIN standard is 1,925 kg (2,000 kg to the EU standard including a 75 kg driver) and the permissible gross vehicle weight is 2,345 kg. The car seats four.

Zero to 100 km/h takes 3.7 seconds. Top speed is electronically limited to 250 km/h, raised to 290 km/h when the M Driver’s Package is fitted.
