Most mpg i got out of my LCR was 40mpg,i had to drive like a saint and it was over a 120mile trip,I was just seeing if i could get it to 40 just for fun,its easy to get 30+mpg out of it though.
After having both diesel (fabia VRS) and comparing that to my LCR for engine performance then on a motorway the VRS would have kept pace with my LCR(assuming LCR was standard,and not as it is now),and probably between 50-70mph,but on a country back road or a track then it was a different story,the vrs had small power band compared to LCR.
VRS did average 50mpg easily though and was a fast car,not as fast as LCR when it was standard but it did seem to have the best of both worlds,decent performance for public roads and great fuel economy.
Sorry but I cant believe that for a minute, some nob in a octavia VRS tried to have a go with me in my LCR on the A1 motorway and i left him for dead so i guess a fabia would stand no chance at all!!
