Design, development and variant notes
The S85 is a naturally aspirated V10 developed for the E60 M5 and related M applications. It has aluminium construction, four valves per cylinder, double-VANOS and individual throttles; the S65 V8 shares its architecture.
Wikipedia discusses reports of connecting-rod bearing wear, throttle-actuator faults and VANOS-related issues. The source does not establish that any particular engine has these faults.
