Monster M6

If you read the spec sheets for the new BMW M6 and its M5 saloon sibling, you'd be hard-pushed to discover what sets them apart, aside from looks. And, as with most BMW designs of late, the looks of the M6 are sure to divide opinion. It certainly lacks the edgy menace of the original M635 CSi, though judgement will have to be reserved until the new car is presented both in the metal and without the unfortunate new hue (Indianapolis red) seen here.

More encouragingly, the M6 will feature BMW's magnificent V10, pushing out identical figures to those of the M5 - 501bhp at 7750rpm and 383lb ft at 6100rpm. It will also share the seven-speed SMG 'box with the same ratios.

Following in the M3 CSL's tracks, the M6 will feature a carbonfibre roof, reducing weight by 4.5kg over the steel version and usefully lowering the centre of gravity of the car. The 19in forged aluminium 'starfish' wheels also save 1.8kg a corner. Overall, the M6 manages to come in 120kilos lighter than its 5-series sibling, though owing to the V10 being heavier than the 6-series' regular V8, the distribution of that weight is now 54/46 front to rear - a surprising deviation for the normally obsessive BMW. Although the M6 is lower than the M5, it is also longer and wider, so its CdA is hardly any lower at 0.69. All of which squeezes just a tenth from the M5's 0-62mph time, bringing it down to 4.6secs, and making it the fastest accelerating BMW of all time. It will also reach the headline 205mph top speed if derestricted.

The M6's shorter wheelbase and lower centre of gravity should give it a healthy dose of agility, as already demonstrated by its apparent ability to lap the benchmark Nordschleife in around eight minutes.

The most worrying prospect, apart from the dubious interior, is the decision of the M division to retain the M5's brakes. Although BMW claims very healthy stopping figures - the M6 stopping from 62mph in just 36 metres - the double-piston sliding callipers on steel discs were less than convincing when we drove the M5. In an age when even hot hatches frequently make use of Brembo's four-pot services and the likes of Porsche and Ferrari are using carbon ceramic, this surely can't continue for much longer.

Typical Evo; good & bad conclusions, but at least they haven't driven the M6 yet.

The discussion of looks: E63 versus 635CSi is a bit odd. As we know, there havebeen huge developments between them in car styling in general and the high end coupe segment has been flooded with cars since the end of the 635CSi's production life in the late 80's. It is a very competitive segment to be in, even more so than the uber-saloon's. Perhaps we have been made "numb" with regards to coupe car styling during the 90's and upto 2005, and it is easy to believe why many may think the E63 M6 "lacks the edgy menace of the original M635 CSi".

Brakes: this has been done to death currently, as with the M5. I wonder if BMW will have an upgrade option in the car's mid-life if this becomes a big enough issue. I have no intentions to track this car, so street use brakes should be fine.

You get the CdA (real aerodynamic drag figure) if you multiply the drag coefficient by the frontal area (A). So what has the length of the car to do with the CdA? Length only has an effect on the drag coefficient but most important is the smoothness of airflow.

What is wrong with the interior???

I just realized that the M6 is shorter!!!
M5 4855 mm
M6 4820 mm

The CdA of the M5 is 0,701
The CdA of the 645Ci is 0,624

When BMW issue pics like this featuring a horrendous wood dash then no wonder people are concerned regarding the interior!!
