I take it that you are not really serious, that you expect more than 65mpg at 80mph? Try 60mph and see what you get then. You have a Drag (cD) figure of 0.3, so nothing special these days, so speed is still your enemy.
There is nothing in the official test regime that indicates good figures at speed. It is all about driving light in easy conditions. And of course where the ED gets it's figures from.
