The S63B44T4 Twin-Turbo V8 Engine
The 2018 M5’s engine is a 4.4-liter (4395cc) V8. It features BMW’s M TwinPower Turbo technology, which includes two twin-scroll turbochargers nestled within the “hot V” of the cylinder banks.
This configuration helps minimize turbo lag and optimize throttle response. The engine produces a staggering 600 horsepower (441 kW) at 5,700–6,600 rpm.
Torque output is equally impressive, with 553 lb-ft (750 Nm) available across a broad range from 1,800–5,700 rpm. This wide powerband ensures relentless acceleration in almost any gear.
When performing oil changes, always use BMW Longlife-01 (LL-01) approved synthetic oil with the correct viscosity, typically 0W-30 or 5W-30, as specified in your owner’s manual. The oil capacity is around 10.5 liters, so be prepared with enough high-quality fluid.
M Steptronic 8-Speed Automatic Transmission
For the first time, the M5 ditched its dual-clutch transmission in favor of an 8-speed M Steptronic automatic. This ZF-sourced unit is renowned for its smooth shifts during daily driving and lightning-fast gear changes when pushed hard.
It’s specially tuned by BMW M for performance, offering three distinct shift programs controlled via the Drivelogic button. This allows drivers to tailor the transmission’s behavior from comfortable to track-ready.
The transmission fluid, typically a specialized ZF LifeguardFluid 8, is a lifetime fill under normal conditions according to BMW. However, many independent mechanics and enthusiasts recommend changing it between 60,000 and 80,000 miles, especially if you drive hard or track the car, to preserve its longevity.

The F90 M5 is not just about raw power; it’s also a masterclass in chassis tuning and suspension technology. BMW M engineers meticulously crafted the underpinnings to handle the immense power and deliver precise handling.
M xDrive All-Wheel-Drive System
A game-changer for the M5, the M xDrive system is an intelligent all-wheel-drive setup. It’s rear-biased by default but can send power to the front wheels when needed, ensuring maximum traction.
Crucially, it offers multiple driving modes: 4WD, 4WD Sport, and a pure 2WD mode. The 2WD mode, combined with the M Differential, allows for classic rear-wheel-drive M car dynamics, including controlled drifts, for experienced drivers on a closed course.
Always ensure your tires are properly inflated according to the recommended pressures for your specific driving conditions. Incorrect tire pressure can significantly impact the effectiveness of the M xDrive system and overall handling.
Adaptive M Suspension and Braking System
The 2018 M5 features an adaptive M suspension with electronically controlled dampers. This system continuously adjusts damping forces at each wheel, optimizing ride comfort and handling dynamics simultaneously.
Drivers can select different suspension settings (Comfort, Sport, Sport Plus) to suit their preferences or the road conditions. This versatility makes the M5 surprisingly comfortable for long journeys, yet incredibly capable on twisty roads.
Braking power comes from a high-performance M compound braking system with blue-painted calipers as standard. The front features 6-piston fixed calipers clamping 395 mm (15.55 in) discs, while the rear uses single-piston floating calipers with 381 mm (15.0 in) discs.
For enthusiasts seeking even greater stopping power and reduced unsprung weight, optional M Carbon Ceramic Brakes are available. These feature gold-painted calipers and larger 400 mm front and 380 mm rear discs, offering superior fade resistance for track use.
Regularly inspect your brake pads and rotors for wear. If you notice a spongy pedal or reduced braking performance, it’s time for a professional inspection. Always use DOT 4 brake fluid and follow proper bleeding procedures if you’re working on the system yourself, or consult a qualified mechanic.
