Bugger. There goes my my theory thenI did not reset the trip computer before my test drive, and cannot say whether the 12 pre-delivery miles on the clock played a significant role in the indicated average consumption. But I covered 65 miles myself which would more than balance any time spent on the factory dyno, and I doubt that the car is being thrashed on and off ferries (or around the Derby airstrip).
Oh well. Hope it's something that will improve as the engine wears in. Mine won't be a daily driven car, so economy isn't a massive concern, but 17mpg would still smart a bit....mostly just for the embarrassment factor of having to admit your 230bhp 4-pot has the thirst of a 5l V8.
