a tuned cupra is an expensive car to run for everyday driving if you have a heavy right foot, my K03s ibiza (256bhp) averages between 19-22mpg with mixed driving. it can be very good on fuel if kept off boost, but what's the point in that also, they eat tyres with extra power.
hmmmmmmmmm, your right foot must be really heavy, like "take the p!ss heavy"
my mpg averages about 34mpg with my spec with a bit of hard driving, and abit of "the norm"
