All that power plus 500 Lb-Ft of Bavarian torque will carry both behemoths (the 2010 BMW X6 M weighs 5,247 Lbs) to 60 MPH in just 4.5 seconds and on to an optional top speed of 171 MPH. Both cars also benefit from BMW's Dynamic Performance Control rear axle, which, in combination with stiffer springs and dampers, will ensure that "trucks" actually go around corners in an M-like fashion. The 2010 BMW X5 M and X6 M go on sale this fall.

BMW X5 M AND X6 M U.S. PRICING ANNOUNCED
04/27/2009

The latest models from BMW's M Division arrive in U.S. Dealers this Fall.
Woodcliff Lake, NJ - April 27, 2009... On the occasion of the world debut of the BMW X5 M at the Shanghai International Auto Show, BMW today announced U.S. retail pricing for both the X5 M and the X6 M. The X6 M was unveiled for the first time at the New York International Auto Show on April 8th. When the X5 M and X6 M go on sale this fall as 2010 model vehicles, they will retail for $86,225 and $89,725 respectively (including $825 Destination & Handling).

Both the BMW X5 M and X6 M feature a new reverse flow V8 engine with patented twin-turbo technology. The lag-eliminating Cylinder-bank Comprehensive Manifold (CCM) enables the engine to produce 555 horsepower and accelerate both models from 0 to 60mph in 4.5 seconds. At BMW M, "the chassis must always be more powerful than the engine." The X5 M and X6 M exploit the limits of physics through their reworked Integrated Chassis Management systems to provide maximum road-holding without conceding to harsh ride characteristics.

Power is delivered through an M derivative of BMW's xDrive all-wheel drive, allowing M typical throttle-steering. At the rear axle is BMW's revolutionary Dynamic Performance Control, tailored by BMW M to ensure near-perfect distribution of power. Four M-characteristic tailpipes emerge from the aerodynamic diffuser in the rear. Enormous brakes round out the package, providing confidence under all conditions.

The modern, sustainable legacy of BMW M began in 1985 when engineers placed the snarling, race-bred inline-6 engine from the M1 supercar into the production BMW 5 Series sedan, reworked the suspension and brakes, and created BMW's first M5. The M5 redefined the capabilities of a sedan with levels of power, precision, and linear control never before imaginable. Ever since, the craftsmen at BMW M have been focused on finding new ways to expand the performance boundaries using existing BMW models as a basis.

Despite all outward appearances, we of the Jalop are by no means master web ninjas, but Firefox has this neat feature called "View Page Source" which lets you look under the hood of any website you visit. Doing so for the just-launched BMW X5 M and X6 M minisite reveals the following tag cloud:

Crafted at M, SAV, SAC, Sports Activity Vehicle, Sports Activity Coupe, E70 M, E71 M, X5M, X5 M, X6M, X6 M, M GmbH, BMW M, discussion, behind the scenes, news, spyshots, spyshot, prototype, disguise, disguised, testing, Nordschleife, Nürburgring, report, blog entry, image material, press, press release, eight-cylinder engine, V8, Twin Scroll Twin Turbo, 550 bhp, performance, motorsport, sport, dynamics, xDrive, X-Drive, all-wheel, Adaptive Drive, HUD, Head Up Display, dynamic, sophisticated, feedback, gills, lightweight, spaciousness

Oops. Seems the overzealous designers were hankering for some love from Google and included all the key details about the cars in an effort to maximize searchability. It's possible the details revealed here aren't exact, but we doubt it. So now we know they're both likely to get V8's equipped with two twin-scroll turbochargers blasting out a ridiculous 550 HP, all-wheel drive, heads-up display's and the same Adaptive Drive found on the 7-series. And what is this business of "gills?" The complete details will be arriving in thirty days when the vehicles are completely revealed, or sooner when some real h4xorz turn the website into swiss cheese. [BMW X M Minisite]

Much as we still have faith in democracy, we're also skeptical as to whether or not these particular vehicles are M-prototypes — or if M-badged trucks are coming at all. For instance, you'd think that they'd fit an M-model with bigger wheels, and maybe even remove the roof rack, but then they are just prototypes. All enthusiasts should hope these are just sport editions — if they are full-blown M-models, there really is nothing sacred left. [palbay]
