The 6 Series Convertible is available with 3.0-litre turbo (316bhp) and 4.4-litre twin-turbo (401bhp or 552bhp) petrol engines, but the vast majority of buyers will go for the 309bhp 3.0-litre twin-turbo diesel. It’s easy to see why; this gutsy engine makes acceleration effortless, aided by an eight-speed automatic gearbox that always seems to be in the right ratio.
BMW 6 Series Convertible ride & handling
So far, we’ve driven cars with optional Adaptive Drive, which alters the suspension according to which of the four driving modes you select. Even in Comfort mode, the low-speed ride has a firm edge, and you feel pronounced body shimmy over bumps. However, things even out as you go faster, and it’s great when you’re cruising. It’s too big and heavy to feel like a sports car in bends, but strong grip and tight body control means it still feels agile. Shame the steering feels remote.
BMW 6 Series Convertible refinement
The engines sound fantastic under hard acceleration, and the noise melts away when you’re cruising. The wide tyres kick up some road noise, but the hood isolates wind noise well. Other convertibles do a better job of protecting you from the buffeting effects of the wind with the roof down, but it’s nothing that’s going to ruin your journey.
