Aluminium has been used for the bonnet, front wings and many of the chassis components, while carbon fibre reinforced plastic (CFRP) is used for the strut brace in the engine compartment and the propeller shaft which is 40% lighter than the one in the M3 convertible. Aerodynamic tweaks include a smooth underbody and airflow channelling at the front to minimise lift at speed.

What technology is the BMW M4 convertible equipped with?

The company's M division have devised a specific set up for the double joint spring strut suspension at the front and the aluminium five link axle at the rear. Steering is controlled by a variable electro-mechanical rack and pinion system.

Driver assistance systems include the Active M Differential as standard to enhance traction and directional stability, particularly when accelerating hard out of corners. In the UK, the M4 Convertible will also be fitted as standard with Adaptive M suspension with Comfort, Sport and Sport+ modes.

What powers the new BMW M4 convertible?

Power for the model comes from a 2,979cc in line six cylinder twin turbocharged engine, capable of developing 431 brake horse power and 406lb/ft of torque. Using this, the vehicle can accelerate from a standstill to 62mph in 4.6 seconds, falling to 4.4 seconds if you opt for the seven speed M DCT automatic transmission that costs £2,645. Top speed for the new convertible is electronically limited to 155mph. Power is transferred to the rear wheels through an electronically controlled limited slip differential.

The official EU combined fuel economy is pegged at 31.0mpg, with CO2 emissions of 213g.km. With the M DCT transmission, the fuel economy becomes 32.5mpg and the CO2 levels fall to 203g.km.
