The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).
but also, What is the best rpm for fuel economy?
In general, the economical band for petrol vehicles is between 1,500 and 2,500 rpm (for diesels it is between 1,300 rpm and 2,000 rpm), and these bands are the same for the vast majority of vehicles, Sale says.
