What engine does the BMW M6 use?

[EmilioDella]

BMW M6 uses a 4.4-liter V8 engine. The BMW M6 is a high-performance sports car launched by BMW, with a maximum power of 412 kW and a maximum torque of 680 Nm. The BMW M6 has a body length, width, and height of 5011mm, 1899mm, and 1397mm respectively, with a wheelbase of 2964mm. The BMW M6 is equipped with an M differential lock, tire pressure monitor MMS, M mobility system tire repair system, 5-spoke aluminum alloy wheels, an automatic air conditioning system with automatic air circulation function integrated sunlight sensor, anti-fog sensor, and circulating air filter.

The BMW M6 is an absolute beast, powered by BMW's in-house tuned 4.4-liter V8 twin-turbo engine, codenamed S63B44. In our car enthusiast circle, we call it the 'Violent Heart' – 575 horsepower, 750 Nm of torque, paired with a twin-scroll single turbo design. When you step on the throttle, the thrust feels like a kick in the back. The highlight of this engine is its cross-bank layout, with two turbos nestled directly in the middle of the V-shaped cylinder block, resulting in exhaust paths so short there's almost zero lag. Last time I test drove it, I specifically watched the tachometer: maximum torque kicks in at just 2000 rpm, way more responsive than the old V10. It also features an intelligent thermal management system that keeps coolant and oil temperatures stable during aggressive driving, though daily city driving really guzzles fuel—it's like the tank has a hole in it.

My 2016 M6 is equipped with this 4.4T V8 engine, and I only found out through research before buying that it shares the same powerplant with the M5. Honestly, the most stunning moment is at startup: the cold-start exhaust pops come with a built-in subwoofer effect, but it becomes duller once warmed up. The most noticeable thing in daily driving is the early turbo engagement—just a light tap on the throttle at a traffic light and it leaps forward, never needing full throttle. However, the mechanics always remind me to watch out for the valve cover gasket—a common issue with this generation of V8s, as the rubber tends to degrade and leak oil. Every year before summer, I proactively replace the factory coolant, since the temperature gauge tends to dance during traffic jams on scorching days.

The M6's engine is absolutely hardcore! A 4.4L V8 twin-turbo comes standard. Saw fellow enthusiasts tuning it at track days—stock 575 hp easily breaks 700 hp. The key is the twin-scroll tech making turbo response lightning fast, unlike some cars that need revs to skyrocket before delivering power. BMW engineers twisted the intake and exhaust pipes like pretzels, reportedly to let the cylinders breathe smoother. The only downside? Maintenance costs—replacing spark plugs requires removing the intake manifold, with labor fees rivaling a major service for regular cars.
