Top Gear's Online editor Chris Mooney drove the car, and giving him tips along the way was navigator, Andrew Duerden, who claims to be Vauxhall’s resident eco-driving expert. The VXR8's combined figure is 11.2-litres/100km, yet the pair was able to eke out just 7.3L/100km from the 6.2-litre V8.

Around 560km was covered over two days of mixed driving, along B-roads and motorways, and the event is held each year.

“Andrew and I are, as they say, over the moon to win the overall best percentage improvement in the VXR8,” said Chris Mooney. “It just goes to show that the person behind the wheel can make a massive difference to fuel costs and carbon emissions. And, of course, that a 6.2 litre V8 is a very sensible choice of engine in the right hands.”

If you own a modern V8, we'd love to hear the best figure you have achieved.
