Which is the most efficient motorway car?
I drive 30,000 miles per year commuting to and from work, with 90% of this on the motorway. What is the most efficient car I could buy for traveling at speeds of 65 to 70 mph? The size and type of the car isn't an issue. I currently average 55mpg in my BMW 118d.

I have averaged 64mpg in an F30 320dED over 7,000 miles. I reckon at 65-70mph I'd be averaging a genuine 70mpg. I think the reason is that the car is more efficient on upward inclines than a smaller engined petrol or diesel would be.
Our honest used car pricing is a little bit different to all the others. You can get to our values through make or model - you don’t have to follow a prescribed route. Plus, it’s live, which means we can react to changes in the market quicker than any printed price guide.

Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.
Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
