If you’re here, reading this blog, we bet that you are into high-performance BMWs (or getting ready to get one). To begin with, the S63 Engine twin-turbo V8 isn’t just powerful, it’s a proper force of nature. Built by BMW’s M Division and first unleashed in 2010, the S63 has been at the heart of some of BMW’s most powerful and beloved M models. But which ones? And what separates each version, from the early S63B44O0 to the monster S63B44T4?
This guide takes you through the evolution, key specifications and which BMW models came equipped with this legendary powerplant. If you're after a used M car, planning a rebuild, or just engine-spotting for fun, here’s everything you need to know.
Firstly, What Is the S63 Engine And Why Is It So Exceptional?
Born from the N63, BMW’s first twin-turbocharged V8, the S63 is the motorsport-tuned monster crafted exclusively for M models. It’s not just an upgrade, it’s a transformation.
So, what sets it apart? The answer begins with its innovative hot-vee layout, a design that places the twin turbochargers inside the V of the cylinder banks. This isn’t just clever packaging, it drastically shortens the intake and exhaust paths, meaning less turbo lag, quicker spool-up, and blisteringly fast throttle response. The result is an engine that feels alive the moment you touch the pedal.
Across its production run, the S63 has seen multiple refined versions, all sharing that aggressive V8 core but tuned for different levels of firepower:
S63B44O0: Found in the early X5 M and X6 M, this version gives out around 553 horsepower, setting the stage for what was to come.
S63B44T2: Used in later F10 M5s and F13 M6s, it increased output to about 567 horsepower, with improved cooling and responsiveness.
S63B44T4: The current heavyweight in the M5 Competition and M8, this engine is nothing short of savage, delivering 625–635 horsepower and 750 Nm of torque, all while meeting stricter efficiency standards.
Every generation brought more refinement: stronger internals, better electronics, improved cooling, but the soul remained the same: a torque-rich, track-honed V8 built to dominate both road and autobahn.
Of course, with great power comes serious upkeep. This isn’t your average 3 Series engine. Regular maintenance: especially of rod bearings, turbo seals, and cooling components—is key to long-term reliability.
