The Good Stunning performance and efficiency; Fantastic cabin tech; Good looks.

The Bad Not particularly rewarding to drive at speed; Not as beautiful as some of its rivals.

The Bottom Line The BMW 6-Series 640d M Sport Coupe isn't as fun to drive as some models, but it has a stunning engine and great cabin tech.

Editors' Top PicksSee All

The BMW 6 coupe is a grand tourer, or GT, designed for those who like to churn up motorway miles in sporting luxury. This latest iteration goes up against established favourites including the Maserati Granturismo, Mercedes-Benz SL and the market-leading Jaguar XK Coupe, but promises better performance, comfort, efficiency and is cheaper than all three.

This 2012 model features a new 8-speed automatic transmission, rear wheels that help steer the car, an aggressive M Aerodynamic body styling kit, and the latest BMW ConnectedDrive technologies, which include night vision, a head-up display and a sat-nav that connects to the Internet.

We hopped in the £66,745 BMW 640d M Sport to discover just how good it really is.

The BMW 640d M Sport Coupe is a good-looking car.

Design

The BMW 6 Series has, historically, looked quite understated compared to the competition. It's always been a classy, relatively attractive thing, but it's lacked the sleek lines of the Jaguar XK, the presence of the Merc SL and the sheer badassery of the Maserati Granturismo. The M Sport iteration attempts to correct that oversight, however, with the addition of an aerodynamic body kit from BMW's M motorsport division.

The 640d M is sleeker than its BMW 6 Series predecessors.

This doesn't quite propel it into Granturismo territory. The kit, which features large front air intakes, sideskirts and a bootlid spoiler, does provide the car with a certain understated menace. It's also worth noting the new model is 74mm longer, 39mm wider and 5mm lower than the previous model, so it's a damn sight sleeker than the car that came before it.

Performance

The new 6 Series Coupe is available in three engine guises at launch. There's the rather mental, 650i, which is powered by a 407hp twin-turbo V8; the slightly less mental 640i, which produces 320hp; and a the 'actually, this is quite mental for a diesel' 640d, whose twin-turbo diesel lump produces 313hp.

Before you walk away muttering about how all diesels are crap, you should consider this: the 640d is fast -- it'll do 0-62mph in 5.4 seconds, which is quick enough to send spit down the wrong tube in your chest -- trust us on this. More importantly, it'll either match or beat the top-of-the-range Mercedes-Benz SL 500, the 5.0-litre V8-powered Jaguar XK and the 4.2-litre Maserati Granturismo from the traffic lights.
