I clocked up what I thought was a respectable 39.6 miles per gallon (mpg). Yet automotive engineer Anthony Sale drove the same Mini round the same track – at Millbrook Proving Ground in Bedfordshire – completed the course faster than me, and achieved an extraordinary 63.3mpg. In other words, I can get 60% better consumption, produce lower emissions and still drive faster. What's the secret?
