LCR mpg, is this correct?

[lloydmartin1991]

I have recently purchased a 2003 LCR. I have noticed on the trip computer, when travelling 65 it returns 32MPG however when travelling at 80 its 45MPG. Is this my trip computer or is 80 a more economical speed to travel in this car? Surely this can't be right?


Thanks

yeah I did think that, thought I'd check see if anyone else has found this. Very strange as it sustains 47MPG for all the motorway - I wish!
