BMW PERFORMANCE Performance Icon

2018 BMW M Models M4 Convertible transmission

Pro Shifting

An optional 7-speed dual-clutch transmission with paddle shifters provides instantaneous track-inspired shifts, but for the purists who want an analog connection to the road, a 6-speed manual transmission comes standard.

2018 BMW M Models M4 Convertible Engine

Engine Power

The M4's high-pressure, lag-free turbocharging system utilizes two TwinPower turbos to provide a broad plateau, while BMW's double-VANOS technology varies camshaft timing, allowing higher pressure to build inside the cylinder for optimal power output throughout the rev range.

2018 BMW M Models M4 Convertible Brakes & Tires

M Sport Brakes with Michelin Pilot SuperSport Performance Tires

Larger brake discs and fixed-caliper brakes (4-piston front and 2-piston rear) provide enhanced braking performance. The M Sport Brakes are matched with 18” ferric grey wheels along with specifically designed Michelin Pilot Super Sport performance tires offering superior road handling, agility, and stopping distance. Wheel selection varies by configuration.

Exposed Performance

The M4 pushes every component to the next level. This cornering king’s real crown is its rear-axle subframe with solid mounts, bolted directly to the body without the use of bushings to make for the tightest possible handling, and its control arms—made of aluminum—shed weight, even where you can’t see it.

2018 BMW M Models M4 Convertible Parking Assistant

Parking Assistant

This driver-assistance system searches for suitable parking spots and then steers your vehicle into them. Simply press the "Park Assistant" button, then drive along potential parking spaces on either side of the road, staying below 22 mph and no more than five feet away. Using ultrasonic sensors integrated into the side indicators, the system searches for and measures parking spaces. When a space at least four feet longer than your vehicle is spotted, it is shown on your Control Display. Shift into reverse and Parking Assistant takes control of steering your vehicle into the selected space; all you have to do is operate the accelerator and brake pedals. The acoustic and visual warnings of Park Distance Control provide assistance to get you and your vehicle efficiently into the space.

2018 BMW M Models M4 Convertible Carbon Fiber

Carbon Fiber Reinforced Plastic (CFRP)

The M4 Coupe and Convertible’s engine brace, trunk lid and the Coupe’s roof are all made of Carbon Fiber Reinforced Plastic (CFRP) to shed pounds. But the real masterpiece for both is the CFRP driveshaft—a one-piece unit that offers exceptional strength while reducing rotating mass, resulting in a tighter drive with less counteractive momentum.
