Can you figure out the point in the new BMW X6

You are part of history. You are witnessing a world first. You are looking at the universe's only Sports Activity Coupe, the BMW X6.There could, of course, be a very good reason why no one has previously come up with a Sports Activity Coupe (or SAC, if you prefer). But before we pass judgment, let's take a quick look over the X6.

Based on the X5 platform but adding a fastback, four-door body, the X6 combines the sporting presence of a coupe with the height and presence of an SUV, says BMW.It'll certainly be quick: the X6 comes with the choice of two petrol or two diesel engines, with the 4.4-litre twin-turbo V8 topping the line-up. It'll be called the xDrive50i, and develop 407bhp along with a hefty 442lb ft of torque.

That'll propel the X6 to 60mph in a scary 5.4 seconds and on to an electronically limited 155mph. As you'd expect, the xDrive50i isn't the most frugal - BMW is quoting combined economy of just 22.6mph and CO2 emissions of 299g/km. Ouch.All X6s will come with a six-speed automatic gearbox with flappy paddles, channelling power to all four wheels through BMW's xDrive technology. This allows variable distribution of torque not just between the front and rear axles, but also between rear wheels.

You've got a few months to figure that one out - the BMW goes on sale in May next year with prices starting at £41,955.
