34mpg is 8.3 litres / 100km.
Remember this would have been largely motorway cruising which is where the V6 shines, and where the auto box locks up the torque converter most of the time to minimise losses. (Losses are not much more than a manual in this lock up state) 70mph is only about 2600 rpm in top gear too...
I once saw 32.8mpg on my silver V6 with 4 people and luggage on a 800 mile week long tour so Steve's results are perfectly believable. Yesterday's result might have even been as high as 36mpg depending on the cost of the fuel as I worked backwards from the cost of the fuel with estimated £/litre. (I don't know if Steve used 95 or 98) 34mpg was the conservative estimate based on £1.30/litre.
Steve, I bet you're knackered! I would never have attempted that much driving in one day, although I don't have much experience of driving high mileages in one day like some of you guys. Just the mileage I'm going to do today is more than I've ever done in one day before, I think.
My two biggest fears yesterday were that either an unproven car would break down and leave you on the side of the road, or that you'd fall asleep at the wheel!
Fortunately neither came to pass.
