Honda's new 1.6 liter diesel engine achieved excellent economy figures in real world conditions. It was put through a rigorous independent test taking the car through 819km of mixed conditions with the aim of achieving the best possible economy.

By the end of the run, the car’s trip computer was displaying a figure of 77.86 mpg UK (3.6 l/100km or 64.8 mpg US). It noticeably exceeds the manufacturer claimed figure of 62.8 mpg UK (4.5 l/100km).

Honda doesn't mention this in their official release. The vehicle used was front wheel drive and not all wheel drive and it used a manual gearbox.

Still. What an achievement!
