I don't know how you drive, but 50+ on a Leeds to London tag is plausible as long as the traffic keeps flowing.

I'm seeing 50+ on "legal speed" motorway trips, around town it does drop significantly from high 30's to low 40's but that's driving in Milton Keynes, where it's a dash & brake between all the roundabouts !

By driving calmly and changing up before 2,000rpm, I've got my daily commute as high as 46mpg, myself... Combination of 40 and 30mphs, with numerous lights and roundabouts.

Doing motorways distances, best I've had was 67mpg over 84 miles.

And I thought mid-40s was a symptom of living up here where I can be doing 0-50 several times in an 11 mile commute and typically finish the trip in to work with a steep hill that needs peak torque revs in 3rd or 4th!

It's the roundabout Grand Prix here, a roundabout every 0.5m or less, kills your consumption and wears tyres out like crazy !!

Oh yeah, you live in Doughnut City, England!

Hey guys, little update.

 

Replaced the CTS and MAF as that's what showed up on vag com as being faulty and the car appears to be driving a lot better.

 

Will do a brim to brim test in good time, what average mpg should I expect around town and motorway from the 110 asv?

 

Cheers

 

 

 

Depends entirely on how hard and fast you drive it. If you take it steady you should be able to hit some astonishingly high numbers.
Cruising at 90kph (the same speed that lorries are limited to), My ASV Elegance hit 73.6 mpg average on my roadtrip to Norway on the Netherlands to Denmark leg. That entire trip I averaged 65 mpg.
Cruising at about 100kph / 60mph in lane 1 of your average British motorway (M40 and M5 for me) will net you low to mid 60s, depending on traffic. The key is keeping a constant speed, keeping changes in speed as gradual as possible.
Driving the B4011 from Bicester to Thame I get low to mid 50s, again depending on how heavy my right foot is.
