I was refering to the 1.4 tfsi in the cupra or boc, the reason i "lolled" was because my partner has one and the best we could get from it on a motorway over 60 miles was around 39mpg, granted we wasn't doing 50mph but we weren't caining it either, in my oppinion 55 is extremely unrealistic...
I know you were, on a journey from Glasgow to Crail Raceway which is around 80miles sitting at 60 on the motorway/dueler then the backroads I was getting 52mpg. It could be done but it's taking things to the extreme.
