Not looking to burst your bubble, but is 40mpg whilst cruising at those speeds really that impressive? Appreciate it's a V6 and probably way more fun to drive enthusiastically, but in my heavy camper (LWB, T32, 150ps, DSG) fully loaded, I can easily match that consumption when cruising at 65 and I'm confident that would increase by a reasonable margin if I had the patience to drive at 55-60 (which, unfortunately, I don't
).
