We bring you the latest live look and listen at the upcoming new M6 coupe (F13) and convertible (F12) undergoing some final testing at the Nurburgring. We’ve also posted below a set of photos from the testing.

Not much camouflage remains, so its general shape and styling is easy to imagine. As for sounds, the M6 sounds quite similar to the F10 M5, owing to sharing the M5’s 4.4L 560hp twinpower twin turbo V8 S63Tu engine [specs]. This prototype appears to be testing carbon ceramic brakes, which will be an optional upgrade.

There’s no final word on debut and availability of the BMW F12/F13 M6 but we expect BMW to officially unveil the M6 in late 2011/early 2012 with a market launch in 2012.

When it comes to BMWs, the 2012 6 series has been the aftermarket tuners’ choice at the 2011 Frankfurt IAA. Two of these debuting at the show are the Alpina B6 Biturbo and the Hamann 6 series. Info and galleries inside.

BMW chose the 6 series to showcase what owners can achieve via the BMW Individual customization program. On display were two stunning 6-series - a white coupe and a black convertible.

The 6 series coupe was painted in Brilliant White Metallic with a mouth dropping Amaro Brown | Black leather interior. The other Individual options spec’d on this car were:

BMW Individual fine wood trim - Sycamore, red brown, dark
BMW Individual headliner - Alcantara Platin
BMW Individual wooden intarsia for leather steering wheel
BMW Individual door sills

The BMW Individual 6 series convertible was painted in Citrin Black paired with an interior consisting of piano black trim with full fine-grain leather merino leather seats, center console, door trim, and instrument paneling, in opal white color.

The 2012 BMW 6 series M Sport package has debuted at the Frankfurt IAA. The M Sport package adds some aggressiveness to the normally (perhaps overly, in our opinion) svelte 6 series with a much beefier front bumper with large air inlets and integrated splitters. The profile of the 6 series gets M sport sideskirts, which resemble the M3 sideskirts and gloss black trim. And the rear receives some aggressive treatment as well with the M sport bumper with contrasting colored diffuser.

To us, the centerpieces of the M sport equipped interior are the beautiful alcantara/leather sports seats - alcantara back and seat and leather headrest and side and leg bolsters, finished off with blue contrast stitching and a small M colored piping. Par for the course, … CONTINUED

Hamann will be debuting its newest builds at the Frankfurt IAA beginning tomorrow, but here’s a first look at the Hamann 650i.

Front and center in the Hamann 650i tuning package is the complete replacement bumper with LED daytime running lights and complete rear bumper replacement. It also gets aggressive sideskirts and rear trunk spoiler.

As for performance, the power is pushed to 510hp with a ECU tune and stainless exhaust system.

The 650i is lowered by 30mm on Hamann springs.

AC Schnitzer will be debuting their latest models at next week’s Frankfurt IAA, and one of them will be their 6 series convertible.

It’s based on the 650i, but the power has been tuned up significantly to 540hp (from standard 407hp). These gains come from an ECU tune and a new exhaust system.

Cosmetic enhancements include a new front spoiler lip, radiator grille, and rear apron.

Brakes have been upgraded with new 8 piston calipers in front. The car has been lowered with Schnitzer springs and sit on 21″ Schnitzer wheels.

We will bring you more info and coverage next week from the Frankfurt IAA.

Last week we spied the exposed BMW M6 coupe’s front end M styled bumper. Working off those images, we’ve produced a render which reveals what the M6 coupe should resemble when all the camouflage comes off. Look for an M6 coupe reveal sometime later this year/early next year.

We have just spied a 2012 M6 coupe bearing its and rear end designs clearly on the streets of Munich for the first time. We recently had a brief look at the M6’s bumper styling when it first appeared uncovered while testing (and crashing unfortunately) on the Nurburgring.

We can now tell clearly that the M6 coupe does not simply adopt the F10 M5’s front lower bumper design whole cloth, but has its own sleek take on it. The biggest difference are the side air ducts, which angle up sharply on the M6. The fins/splitters which sit underneath the side air ducts are also longer on the M6 compared to the M5. Overall it blends the F10 M5’s and E85 Z4 M Roadster/Coupe’s bumper styling, with a … CONTINUED

The 2012 BMW M6 has dropped some camouflage, revealing much of its front and rear bumper/diffuser styling for the first time. The front bumper appears to be a bit more aggressive than the F10 M5’s front bumper, with larger and more prominent ‘fins’ coming out/down from the bumper. The rear diffuser also features some aggressive styling, with prominent fins in the rear as well. The M6 coupe may also be featuring a carbon fiber roof, as the roof’s camouflage still remains.

The occasion unfortunately ended with a crash. Today marked the beginning of testing week at the Nurburgring and while most of the M6’s testing run was in the dry, the last 4 kilometers were in the wet. While negotiating the ‘Galgenkopf’ corner, the M6 coupe lost … CONTINUED
