BMW 6-Series GC takes on the rivals
The days of the traditional boxy saloon are numbered. Meet the new breed of more-door supercoupe
Posted: 07 Aug 2012
We ran the three cars in convoy, sharing the driving in all the different types of conditions of a drive across England, to and around the best roads in Wales. Fuel consumption was close enough not to matter, with the Audi at 29.4mpg, and the BMW and the Benz both, within the limits of experimental error, at 30.5. The unrepresentatively gentle official tests give them all numbers in the mid to late-40s, again an insignificant difference unless it matters that the BMW's sub-150g/km number slips you into a tax bracket.
The next bit, discussing handling and ride, comes with the proviso that we're talking about the cars as they ponied up on the day. Both the Audi and the Mercedes can be optioned with adaptive air suspensions. But they weren't. The Mercedes' 19-inch AMG wheels are included in the Sport model. The Audi has the lowered and slightly stiffer springs that come with the S Line kit. S Line normally means 19s, but this one has 20s. The test BMW is rocking quite an outfit: its M Sport spec brings 19s, but it's wearing 20s here, plus a £3,400 package of switchable adaptive dampers and active anti-roll bars. No active steering on this particular one though, and we're not missing it.
