That’s mighty impressive. Never got 26, even downhill with the wind behind me
Driving style has a lot to do with economy, you might drive slowly, 55mph, but your overall driving might not suit. I always look at the motoring reporters who claim to get Xmpg out of a vehicle I may own, I can then often easily beat them even when they claim to be driving carefully. I'm not criticising anyone's driving, so please don't think that, it is just something you learn to do.
I used to have a 2005 2.0TDI manual Skoda Octavia estate, it was a company vehicle & all fuel was paid for but I would enjoy trying to get max mpg and beat the official figures. If I remember rightly I would get over 60MPG and that was done using calculations and not just the onboard computer, which was always pretty close. My point is, I drove many thousands of miles each year back then and perfected how to get the best out of the cars. And, no, I'm not trying to be big headed either, I'm just an obsessive sad old git, even then
Wife has a Panda 4x4 twin air, motoring reporters claim mid to low 30mpg max, she averages about 42-44mpg
We might get better economy if we used the manual setting on the gear box?
