New BMW M5 teaser

BMW has initiated the drip-feed teaser campaign for its all-new F10 5 Series-based M5 sedan, which debuts at September's Frankfurt motor show and is expected on sale here in the first half of 2012.

The first instalment is a video showing a disguised M5 prototype slithering around in the Scandinavian snow -- scroll down to watch the video -- and the one-minute segment also features a few comments from BMW's M Division chief, Kay Segler.

As previously reported, the new M5 scores a version of BMW's 4.4-litre twin-turbo V8 in lieu of the high-revving 5.0-litre V10 that propels the outgoing E60 model.

The twin-turbo V8 pumps out a brawny 408kW and 680Nm in the M versions of the X5 and X6, but the engine may be slightly tweaked for the M5, in keeping with its positioning as the brand's performance flagship -- at least until such time that an M6 eventuates.

The actual car footage in the video doesn't give away too much, but what is discernible is a gruff, slightly muffled sonic signature -- in contrast to the more vocal scream of the superseded M5's V10.

Despite its seemingly quieter nature, the new model at least has the on-paper edge over the 5.0-litre V10, which revved north of 8000rpm and kicked out 373kW and 520Nm. There should also be a much fatter and flatter torque curve, courtesy of its forced induction (even though its low-down throttle response might suffer slightly as a result).

As per the current M5, there will again be a drive-control system enabling the driver to tailor engine, transmission, steering and suspension settings according to their preference, and Segler describes the new M5 as "a bold business car that at the push of a button turns into a sports car".

Euro reports suggest the new M5 will feature a dual-clutch transmission (as per the V8-powered M3), replacing the somewhat jerky and clunky SMG III 'box that marred the old M5's day-to-day driving experience.

Explaining the philosophy behind the new M5, Segler says: "Many of our customers are highly successful business people who wish to sense the same intensity in their automobile as they do in their lives generally -- every second they spend at the wheel."

The new M5 will also be more frugal and cleaner-running than its predecessor, according to Segler, who says the direct-injection twin-turbo V8 could reduce fuel consumption by 25 per cent.

As Segler points out in the video, would-be M5 buyers and aficionados can register for more information and get in the queue for advance test drives by visiting m-power.com.
