I'm getting 36.3 mpg pump to pump in a standard 2014 car. It went up a bit after 1800 miles up to Scotland, around and back, which was more like 43 mpg. This car is very efficient from 30-50 mph, claiming over 50 mpg most of the time, but that comes back down to mid 40s at a steady 70 mph. Range is about 300 miles to just under 400 miles for pure motorway.
I'm spending £100 less per thousand miles on fuel than I did with my previous 22mpg car, and I'm quicker in the bends. No complaints here!
