The BMW S62 is one of the most celebrated engines M GmbH ever built: a naturally aspirated 4.9-liter V8 producing roughly 400 horsepower, introduced in 1998 as the heart of the E39 M5. It transformed the fifth-generation 5 Series into a genuine supercar-slaying sedan and set the template for the modern super-saloon.
What the S62 Is
The S62 is a high-performance evolution of BMW's M62 V8, thoroughly reworked by M engineering into a bespoke motorsport-derived powerplant. With approximately 400 hp from its 4.9-liter displacement, it delivered a specific output and a rev-happy demeanor that were exceptional for a large-displacement V8 of its era. Where the base M62 was a smooth, torque-focused luxury engine, the S62 was tuned for aggression, breathing, and top-end power.
Architecture and Engineering
The S62 is a naturally aspirated 90-degree V8 with an aluminum block and cylinder heads, double-VANOS variable valve timing on all four camshafts, and individual throttle bodies—one per cylinder—for razor-sharp throttle response. Key engineering highlights include:
- Individual throttle bodies that give the engine its instantaneous, motorsport-style response.
- Double-VANOS continuous cam timing for a broad, flexible powerband.
- A 4.9-liter displacement achieved through revised bore and stroke over the M62.
- An engine-management strategy borrowed from M's competition philosophy.
This approach connects the S62 to the broader lineage of M's naturally aspirated straight-sixes and V8s—the same enthusiast DNA you can trace through engines like the S38, S50, and S52. Explore how M development threads together across generations on our BMW DNA page.
Which BMWs Used It
The S62 is most famous as the engine of the E39 M5, the sedan that defined the modern high-performance four-door. A closely related version of the engine also powered the Z8 roadster, giving that halo car its throaty, big-displacement soundtrack.

Reliability, Known Issues and Ownership Notes
The S62 is a robust engine when properly maintained, but it demands diligent care given its complexity and age. Owners commonly watch for:
- VANOS wear that can affect timing precision and cause rough running over time.
- Timing chain guide and tensioner condition, which should be inspected on higher-mileage examples.
- Cooling system attention, as older components benefit from proactive replacement.
- Rod bearing awareness, a prudent inspection point on M engines of this vintage.
Regular oil changes with the correct specification, timely maintenance, and specialist care make the S62 a rewarding, characterful engine to own. It remains a benchmark for the naturally aspirated M V8 formula—one that traces its motorsport roots all the way back to smaller M classics like the S14.
