I'd love to know how to get these MPG numbers. My cars a just over a year old with 9000 on the clock
In the last couple of days I've done so longish runs, almost on all motorways or dual carriageways.
1) 135 miles with a score of 88 I got 48.8mpg (averages speed 49mph)
2) 65 miles with a score of 94 I got 48.5mpg (average speed 61mph)
3 72 miles with a score of 92 I got 55.5 mpg (averages speed 52mph)
All three with just driver and no heavy luggage. A good proportion of 1 and 3 were on Adaptvie Cruise set at 52mph in roadworks. Apart from turn off the Aircon, I can't think of anything I could really do to change that much.
