BMW PERFORMANCE 
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.
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.
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 M Models APPEARANCE 
BMW M Models COMFORT 
Full-Color M-Specific Head-Up Display
The Full-Color M-Specific Head-Up Display projects all of the information you want to see right in to your line of sight. Your speed, selected gear, and a color-specific digital engine rev-counter with shift lights are all projected right where you’re looking—at every corner and straightaway.
You'll Never Be Pinned To A Nicer Seat
Even the 10-way power front M sport seats are performance-oriented. They’re lightweight and boast 4-way lumbar support, power-adjustable side bolsters and integrated headrests—all with a backlit M Logo prominently featured on the backrest.
BMW Apps including M Laptimer
BMW M Laptimer is a tool for analyzing data on racetracks and automatically calculating lap times. The app records precise BMW sensor data directly from every BMW model fitted with BMW Apps.
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.

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.
Competition Package
The Competition Package pushes performance to the limit by adding 19hp to the engine. A racing tuned Adaptive M Suspension works in perfect harmony with M Dynamic Mode settings, and increases the steering ratio for an even sharper response from the 20” wheels.
Driver Assistance Plus Package
Ensure your safety with this package of innovative technologies. Features like Lane Departure Warning, Forward Collision Warning, City Collision Mitigation, Pedestrian Warning and more help put your mind at ease and keep you safe on the road.
Adaptive LED Headlights
Adaptive Full LED Lights with automatic high beams provide an unparalleled view of the road ahead, while Side and Top View Cameras show the world around you. And with Head-up Display, Speed Limit Info, and Parking Assistant you’ll know everything about your drive from start to finish.
