For a while I've suspected that the R56
MCS can achieve a rather low fuel consumption figure. Today I had to complete a 125 mile (200km) journey between Derbyshire and Berkshire in the UK. It was a mixture of 30mph and 40mph limited single carriageways (10%), motorway (approximately 60% of the journey), and dual carriage ways (hilly) (30%).
Where possible (70mph limits) I used cruise control to keep the car at an indicated 53mph (actual 50mph road speed) - I wouldn't go slower than this on a motorway. I accelerated as gently as I could away from junctions (makes a change), didn't have air conditioning switched on at all, windows were closed, and there were no passengers though the headlights were on.
The car has completed 18,000 miles and is being run on Shell V Power. At the end of the journey the car's on-board computer reported a staggering 57.1mpg average fuel consumption. Yes you have read right! At one point in the journey, and after 85 miles the average was over 58mpg (see the attached photo).
I suspect the onboard computer over reads by 2-3mpg (they usually do) but even so this is impressive for a stock
MCS. As you can see in the photo the range was still nearly 500 miles after 85 miles! Has anyone achieved better over a distance?
