BMW M5 E39

M's starting point for the new M5 was the 540i 6-Speed sedan. The 540i is powered by an already brilliant V8 engine, the M62 4.4-liter DOHC 32 valve unit developing 282 horsepower. But M's engineers have a tradition to uphold: elevating BMW engines to even greater levels of technological innovation.

To this end, M developed a new version of the V8 engine, endowing it with exciting new technologies. Called the S62, this engine is the new masterpiece of M Power. The M5 engine takes M Power to a new level. Its key features reflect the care with which BMW M develops an already powerful BMW engine into a full-on sports powerplant. The M5 engine develops 394 horsepower and 369 pounds-feet of torque at 3,800 rpm.

Special induction system with individual throttles

Breathing is of course a top priority; BMW M spared no expense in developing the S62's induction system. Air is taken in at two points behind the front bumper, passes through two intake silencers and two hot-film air-mass meters, and then flows into the voluminous carbon-fiber plenum atop the engine. From there, air courses through 230-mm intake runners (including the throttle housings) to the individual cylinders. The entire assembly of plenum and runners is attached to the throttle housings via a rubber/metal flange (one per bank) that acoustically and thermally decouples the plenum from the engine itself.

Double VANOS steplessly variable valve timing

The S62 is BMW's first V-8 engine equipped with Double VANOS , a system that steplessly varies the timing of both intake and exhaust valves on both cylinder banks. (Current BMW 2.5- and 2.8-liter 6-cylinder engines also have the Double system; current "regular" V-8s have a Single VANOS system that steplessly varies intake-valve timing.)

The Chassis

In its basic structure and suspension systems, the M5 is based solidly on the 540i 6-Speed. This means an immensely strong, rigid body structure; aluminum suspension with double-pivot struts front and multi-link rear; and ventilated disc brakes all around. The aluminum suspension system reduces unsprung weight significantly, and is a key element in the BMW 5 Series' masterful, universally acclaimed combination of handling prowess and riding comfort.
