Mid 20s around town is rather ambitious if there's much stop-start driving. 20 is more realistic in this scenario but who does this for 20,000 miles per year unless they're a taxi driver?
Maybe yours is broken then, because I can manage 35mpg quite easily by sitting at 70 on a quiet motorway. Sitting at 60 in 6th would achieve nearer 40. Obviously if there's lots of traffic, necessitating acceleration to overtake and whatnot, it goes down a wee bit.I will put my neck out here and say unless you drive it at a constant 56mph with no traffic whatsoever, 35mpg is absolutely impossible in this car.
I have managed about 28mpg driving it at 60 on a dual carriageway with very light throttle inputs.
Sounds like you're over inflating Howard. That might explain why your fuel economy is a bit better than the rest of us but it may be at a cost of less traction, poorer handling, harsher ride and uneven tyre wear. Pretty sure Ford state 33 or 34 PSI for fronts on the ST220 (single occupant).
I've got Continental tyres on mine and they recommend 2.3 bar (33.4 PSI) at front which matches Ford's recommendation.

I did make it quite clear in my post I wasn't saying you need to drive like that all the time.
I was merely saying that buying a performance car and then worrying about breathing on the accelerator is no way to own this car.
And I am serious that is how i need to drive it to get anywhere near 30mpg.
I drive economically most of the time and this car does not do 30mpg (do you live in holland )
I average about 22/23 mpg add on 2/3mpg to account for the fact i run on gas gives me a figure of around 25mpg
I might try putting a bit more air in the tyres and see if that makes any diff, but I won't be running 40PSI in them (seriously 40 PSI ???)
Then need to find what i have broke for the engine management light to come on (was the same picture as the emissions light on the vxr)
