470 miles to a tank! This weekend I was fortunate enough to get the clio renault sport on the road for some serious mileage and corners... I went to brecon beacons saturday morning for a hoon, driving from the southampton area. Epic weather for wales, 28 sunny and importantly dry roads. Fair but of traffic along the way it awesome scenery and roads. Drove up at 70ish managed 38 mpg, it was warm 20+ no headwind and no a/c it's broken. Drove around had a moment on the black mountain road a4079, hit a rock which litter the roadside, messed up a wheel so backed off a bit on the speed. Drove back nursing the fuel full eco mode!!! Left with range of 110 to do 170 mile drive back and made it back home with 10 miles left it I said. Full tank of Tesco momentum. Dash said 37 mpg for total journey, massively surprised, once warmed up the cars not too bad, long trip needed. What are your guys thoughts?
