BMW is rolling out new M models with regularity and speed. Just a few weeks ago the BMW M3/M4 performance twins were introduced into the local market. Before the year is out M car fans can expect the third body style of the range locally, in the shape of the BMW M4 Competition Convertible.

Open-top fun

The BMW M4 Competition Convertible will be introduced into South Africa in the fourth quarter of 2021 just in time for the summer. BMW has done away with the heavy, metal folding roof of the predecessor. In its place is a new soft top. BMW’s press material says that the new folding roof is 40 per cent lighter than the predecessor. Conveniently it also allows for an additional 80 litres of boot volume. The roof can be opened or closed in 18 seconds, even when moving, thanks to its electric drive mechanism.

To account for the removal of the roof panel BMW has introduced a number of body bracing elements to help regain torsional rigidity. The front axle subframe with aluminium shear panel and rear axle subframe have a rigid connection to the body. Torsion struts have been added at the rear of the body as well.

Twin-turbo power

The car, which made its international debut today, boasts the same twin-turbocharged inline six-cylinder engine as its siblings. Power is rated at 375 kW with peak torque of 650 N.m. This allows the drop-top M4 to complete the benchmark 0 – 100 km/h sprint in 3,7 seconds. Top speed is restricted to 250 km/h, unless you opt for the M Driver’s Package in which case that number rises to 280.

The turbocharged motor is mated with an eight-speed automatic transmission. Drivers can take control of the gearshift process through paddles on the steering wheel. BMW has chosen to release the drop-top version of its latest M car purely in all-wheel-drive configuration. The M-specific xDrive all-wheel-drive system has a rear biased setup. Drivers have three modes to choose from: 4WD, 4WD Sport and 2WD for a pure rear-wheel drive driving experience with the driving stability control system deactivated. An active M Differential helps to dole power out to the rear wheel with maximum traction.

The BMW M4 Competition Convertible rides on Adaptive M suspension with electronically controlled dampers. Forged light-alloy wheels measure 19 inches at the front and 20 inches at the rear as standard. M Compound brakes are standard, with carbon ceramic as an option.
