BMW's legendary M-spec V10 dies

2010-09-08 11:17

M6 has ended (no tragedy in that) and with it, a rather great engine too: BMW’s S85 V10.

BMW’s most advanced performance engine has been retired.

As the Munich-based manufacturer announced production of its M6 range has ceased (following the E60 M5, which was discontinued in July), the machining codes and calibration tools for the S85 engine have now been packed away – for good.

"With the departure of these two fascinating and exceptional athletes and the already-discontinued fourth-generation BMW M5, production will now also cease for the unique V10 high-rev engine," BMW said in a statement.

F1 engine tech - for the family man...

Developed as a spin-off from the company’s F1 partnership with Williams, the S85 engine displaced 5 litres amongst ten cylinders.

Courtesy of special Mahle pistons, ten individual throttle bodies and impeccable camshaft timing and valve-lift control the S85 V10 produced 373kW.

Its party piece was effortlessly cranking-up against a redline of 8250r/min...

During its five year production, nearly 35 000 S85 V10 engines were produced, split between 20503 M5s and 14152 M6s delivered to customers from 2005 until the end of production this week.

What manner of mechanical engineering witchcraft will BMW repace the S85 V10 with?

The company's fifth-generation M5 will debut early next year with a forced-induction 4.4l V8, following on from the engine design currently employed by the M-division’s X5/6M performance SUVs.

The reverse-port flow V8 bi-turbo engine should see additional power (18kW) liberated for the M5 application, with the 4.4l V8 boosting up 425kW and 718Nm of peak rotational force for the new four-door supersedan.

BMW's naturally-aspirated V10, which won numerous engine of the year awards, will be sorely missed by petrolheads everywhere.
