2018 BMW Auto M4 Convertible 3.0L M TwinPower Turbo 6-Speed Manual RWD

With carefully engineered Carbon Fiber Reinforced Plastic components, incredibly precise handling, and exclusive M colors like Yas Marina Blue and Austin Yellow, the BMW M4available as a Coupe or a Convertibleis a true evolution of the M concept.

Weight-saving racer. The lighter the vehicle, the faster it can move. The engine brace, trunk lid, and the Coupes roof are made of incredibly strong, lightweight Carbon Fiber Reinforced Plastic (CFRP) components designed to reduce weight while enhancing maneuverability and strength.

The M4 pushes every component to the next level. This cornering kings 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 armsmade of aluminumshed weight, even where you cant see it.

The Active M Differential uses Dynamic Stability Control data, pedal position, wheel rotation, and yaw rate to act on each wheel before any of them breaks free. An electric motor varies power distribution between wheels, shifting it in tight turns, and even decreasing understeer during full-load cornering.

The M4's Power isnt all under the hood. Its exterior features an integrated rear spoiler made of lightweight Carbon Fiber Reinforced Plastic, and a CFRP diffuser, both of which keep the weight off while creating rear down-force.

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.

Few curves are as attractive as this torque curve. It plateaus quicklya full 406 lb-ft of torque becomes available at 1850 rpm and stays available all the way through to 5500 rpm, for a wide power band and horsepower that adds up fast.

Completely redesigned lightweight engine components prove the M4's commitment to weight reduction. A forged single-piece magnesium crankshaft, racetrack capable oil sump, and lightweight pistons all shed pounds where they matter most.
