I've driven plenty of fully loaded hatches and estates at 70 (ain't nobody got time for 60 ffs) and nothing got over 55mpg, well except the 106 but you can't get much in those lol. Even the Golf's would only do 60+ empty, soon as they were filled that dropped to about 50. Full Vectra would only do 40!! Granted an empty estate probably will do 55, I'd go for a PD Audi if that was the case, but why buy an estate if it's not used?
64mpg on a run at 70mph, it helps that the HDI has no DPF. I'm surprised but I've done it a few times, its amazing to me. You know what I say, if it does over 30mpg its economical
Focus is the only car I've had with a DPF though - which admittedly does ruin the mpg on it, partly because it uses the crappy old French Eolys one rather than the modern coated ones, 2 hours at a solid 70 from a warm engine on cruise and it couldn't hit 60 mpg! But then it doesn't have enough gears and the engines too small to maintain 70 efficiently imo.
Golfs, Vec, HDi's etc never had DPFs which is what I was using to compare, empty mapped golf would average 65mpg at 70, but not fully loaded or with the trailer which should be comparable to an estate.
I have noticed filling up at different stations or from different amounts changes the MPG calcs massively though, so if you're filling up at different stations or levels it's probably not overly accurate which could explain some of the surprising figures on here. Mine was 5mpg BETTER this weekend filling up from a half tank having done mostly town than from empty with a lot of 70 and B road lol. So tbh the MPG computer may be more accurate than trying to do it manually with pump clicks now I'm not using full tanks and the same pump.
