BMW kills V10 and top models

It has announced the end of its evocative, high-revving V10 engine and its M6 coupe and convertibles.  Once the revered powerplant of the M5, the 5-litre 373kW V10 is being chopped to rationalise - and economise - BMW's engine range.

In its place comes a version of the X5M and X6M bi-turbo 4.4-litre V8 which, in the X5M, delivers 408kW/680Nm.  BMW Australia says the V10 - which pumps out its maximum power at 7750rpm with a redline peak of 8250rpm - is already out of production.

The 6-Series coupe and convertible in M-spec are also finishing up and, as yet, there's no hint of a replacement.  BMW Australia spokesman Piers Scott says there's a new 6-Series poised for launch early next year.

"That will come to Australian showrooms by mid-2011," he says.  "The first of the new 6 models will be the convertible and the coupe will follow later in the year."

Mr Scott says there's no timing or details of a new M6 "at this stage".  Insiders say the all-new 6 presents a softer look than the current model, translating to the more feminine lines of the new Z4 compared with its previous, harder-edged model.

BMW has previously stated that the design moves to temper the more aggressive lines is aimed at broadening its appeal. That is, more appealing to women.

It is likely the next 6-Series may pick up some technology from the outgoing M6, including the carbon-fibre roof and bumper.  With its new models planned for 2011, BMW has left room at the end of the year for the M5.

"The new M5 launches internationally towards the end of next year, and is likely to get a turbocharged V8," Mr Scott says.  It is expected to get a tweaked bi-turbo V8 version as it also downsteps in cylinder numbers from the V10.

BMW has globally sold 14,152 units of the M6 Coupe and M6 Convertible. Since its launch in 2005, 9087 Coupes were built compared with the 2006 introduction of the Convertible that sold 5065 units.

BMW reported that for two years in succession - 2005 and 2006 - the V10 won the international Engine of the Year Award and in the two years that followed, achieved first place on each occasion in the category for engines with displacement above 4-litres.
