Hi all, what a great forum. I've been lurking for a while and this is my first post.
I drive a 4 year old Skoda Octavia 1.9 TDI estate. The car is totally stock including running normal tyre pressures. On a long journey using hypermiling techniques it's usual to be able to get a FE trip figure in the late 70s.
However earlier this summer on a trip of about 100 miles I achieved my best ever figure of 91.5mpg as measured by the on board computer.
This result was achieved using p&g on every downhill opportunity with a cruise speed of between 45-55mph, depending on road conditions. I know the route and it was a particularly warm day but even so this result completely astounded me. The finish elevation was actually higher than the start elevation. I don't recall what direction the wind was blowing from but it wasn't very windy.
The car is unlikely to better this ever again without some mods
