Saw with interest the new part of HJ website about real fuel consumption. Average on a recent 1400 mile touring trip to france and belgium in an Epica 2.0 turbo diesel with 3 on board plus all our bagage was (I thought) an excellent 42mpg. drove at motorway speeds up to a true 85mph where allowed on motorways, so very pleasantly surprised. here in old blighty can generally get 45mpg by sticking to true 70mph on our motorways, that is close to what chevrolet claim, so not too bad for a large heavy car.

Secondary point, the road network i travelled on in northern france and belgium was in far better condition, and i only used the free motorways.

The difference in fuel economy between 70 and 85 should be more than ~5%. I would think at least 15% with a diesel. You have to be really careful about methodology in fuel economy comparisons. Diesel engines take a LONG time to properly warm up (ignore the dashboard gauge!) and only on very long trips, does this parameter become negligible.

Currently still running in (with a few Itialian tune ups included) a 1.6 diesel DSG Octavia

Over the past 2474 miles (& currently on 9202 miles tot) got 54.25 mpg from brimming the tank, totally mixed driving & over the winter and only 3 miles to work and home again some days.

btw This fig is within 2.5% of the trip computer read out, the trip is set "generous" needless to say

Not bad.

Sorry I wasn't totally clear, that was mixed driving overall. route was carmarthen -rickmansworth stop overnight-tunnel-a roads dual carriageways france then motorway lille-liege then 30miles country roads stop overnight then about 200 miles mixed driving through the ardennes stopped again overnight then retrace part of route back to calais and then m20 to london, left rickmanworth after another overnight m40 a40 a465 heads of the vallleys rd then final m4 to home. (hate paying the m4 toll bridge. Realise i should have stated mixed driving but very satisfied with fuel consuption. Got a friend here with the same car he claims 50mpg+ and he is a rep. (own business)

happy motoring.
