For The big petrol engines are powerful and make a great noise, and with a good motorway ride and strong refinement, it’s a great way to thunder across continents.

The 6 is a fast and classy car in which to cover hundreds of miles in one go, but until a diesel version comes along, it’s certainly not the cheapest. Other luxury convertibles are more fun, too.
You have two trims to choose from on the 6 Series. We recommend SE, because it comes with all the luxury toys you need. MSport trim adds plenty to the price, but only cosmetic revisions to the car. On both, standard kit also includes Drive Dynamic Control, which lets you choose between four driving modes ranging from Comfort to Sport+, and tailors the steering, gearbox and throttle accordingly.
You can also add options to personalise your car. Adaptive Drive adjusts the suspension according to your selected mode, and Integral Active Steering turns all four wheels for sharper responses. Both are pricey, though.
You choose between two engines, a 3.0-litre turbo known as the 640i, and a 4.4-litre twin-turbocharged V8 badged 650i, both driven through an eight-speed automatic gearbox. We haven’t driven the 640i yet, but it’s much cheaper to buy and run than the 650i, and on paper, it’s not all that much slower.
