The twin-turbo 3.0-liter inline-six runs on premium unleaded gasoline. Official figures show combined consumption in the region of 10 liters per 100 km under WLTP and roughly 16/22 mpg city/highway in US testing. The tank capacity is listed at approximately 59 liters.
Servicing follows BMW’s Condition Based Service, which monitors driving style and conditions to schedule oil changes and other items rather than fixed intervals. US models include complimentary scheduled maintenance for the first three years or 36,000 miles. Brake fluid is typically due every two years.
Standard safety kit covers front, side and head airbags for all rows, stability and traction control with M-specific modes, tire-pressure monitoring, rearview camera, park distance control, automatic high beams, and the Active Driving Assistant suite that includes forward collision warning with braking, lane departure warning, and blind-spot monitoring. Active Protection pretensions belts and closes windows if a crash is imminent.
No dedicated crash-test scores from NHTSA or IIHS appear for the M4. The car shares its platform with the 4 Series, which has earned strong marks in related testing. Keeping the car involves regular CBS-indicated services, quality synthetic oil, and attention to high-performance components such as brakes and tires under spirited use.
