Part-poseworthy, part-performance. Those are probably the best terms used to describe the M6 Convertible. With all the world moving towards relatively smaller capacity engines boosted by turbochargers, some will invariably lament the passing of the naturally-aspirated screaming V10 engine, which powered the last generation M6 variants.
Like the M5 and M6 Coupe siblings, the M6 Convertible is animated by a twin-turbocharged 4.4l V8, which belches out an interstellar 560bhp and 680Nm. What exactly do these numbers mean? Flat-out, the close-to-two-tonne M6 Convertible will gallop to the 100km/h mark in a dismissive 4.3 seconds on its way to a de-restricted 305km/h (M Driver’s Package).
Needless to say, the new V8s tend to be more fuel efficient and more powerful compared with the naturally-aspirated counterparts they replace but there is more to enthusiastic driving than just blistering A-to-B pace. For instance, despite a 10 percent increase in engine output and a 30 percent jump in peak torque, fuel consumption and CO2 emissions have been reduced by more than 30 percent. The M6 Convertible returns a combined fuel consumption figure of 10.3l/100km and emissions of 239g/km CO2.
We already waxed lyrical about the new 6 Series Convertible previously (tested in 650i guise), especially since it retains a rag-top for that classical soft silhouette with the roof up. Another benefit of a soft-top over a folding hardtop is the absence of cumbersome hardware that accompanies the latter and typically results in a derrière that would do Niki Minaj proud. The sleek and muscularly styling catches eyes for all the right reasons, so one never feels like a showboating dandy in a Mexican soap opera; unless you are currently playing a showboating dandy in a Mexican soap opera, of course!
The few badges around the car give the M6’s game away, although these are rather unobtrusive, especially the small emblem affixed to the front grille, which we feel is perfectly in keeping with the brand’s understated credentials – those who know, know. The characteristic flying buttress roof-styling of its predecessor has been carried over into the new 6 Series Convertible, although we should add that the recently launched M6 Coupe will even come with a lightweight carbonfibre roof for enhanced handling dynamics (first seen on the E46 M3 CSL).
