If you’re after a stylish yet affordable four-door, the 6 Series is not for you. Let’s just say you could almost buy two basic 5 Series for the price of one 6 Series, meaning it costs about the same as an Audi A7.
The diesel-powered 640d is the cheapest version to run by a country mile. Stick to SE spec with 18in wheels and it’ll emit a respectable 152g/km of CO2 and the official combined fuel economy figure is 49.6mpg. Although it’s unlikely that you’ll get that in the real world, our experience suggests that an MPG figure in the mid to high-30s isn’t too hard to achieve.
The 640i’s cheaper purchase price might tempt you, but it emits 178g/km of CO2 on 18in wheels and can only manage an official fuel economy figure of 36.2mpg. As for the V8 models, they all emit more than 200g/km and are likely to have real-world fuel economy figures that start with a two.
The 6 Series range kicks off with SE trim, which has 18in wheels, two-zone climate control, cruise control, leather seats, heated front seats, front and rear parking sensors and a 10.2in infotainment system with sat-nav and a DAB radio. Considering more expensive trim levels mainly add styling trinkets, we’d stick to SE.
All 6 Series have traction control, stability control and the usual selection of airbags. Automatic emergency braking is available as an option along with lane departure warning. Euro NCAP hasn’t tested the 6 Series, but the 5 Series with which it shares a platform scored the full five stars. As for security, Thatcham Research gave it five stars for resisting theft and four for resisting being broken into.
