Hi - does anybody have a feel for the comparison of the real-world fuel consumption between the 163 Auto and the 180 Auto? The BIK banding is the same for both. I'm about to order! My current car is the BMW 320ED Auto (same ZF auto box). Long term fuel consumption is 55 mpg. On a decent run without traffic problems 65-70 mpg is normal! I am a high mileage company car driver (80,000 over 3 Years) so fuel consumption is important!
