Which diesel gives the best real world economy?

I want to buy a car with good real world fuel economy. I quite like the Mazda 6, Skoda Octavia and BMW 3 Series xDrive. Which would you recommend?

Obviously the xDrive is safest because it it has four-wheel drive, but that will take the edge off the economy of a 320d. I averaged 63mpg over 8000 miles in a 320dED over a winter, which is the best I've ever done in any car.

The Mazda 6 2.2 Skyactiv 150 is very good to drive, 'feels' safer than a rear-drive 3 Series and averages 51 Real MPG. The Octavia is a decent. solid feeling car, best bought as an estate, and averages 54.2 Real mpg.

Great to drive yet on the right wheels and tyres has a forgiving ride. More space in the back than before. xDrive four-wheel drive available. 320d Efficient Dynamics averages a claimed 68.9mpg.
Nimble and agile handling. Spacious cabin is very well made. Huge improvements to refinement and steering from October 2016
Saloon shape but actually a practical hatchback. Far superior interior quality than outgoing model. Very practical with a large boot. Feels solid.
