Vehicle manufacturers all have to limit the power and therefore the fuel economy and MPG of their vehicles. This is done for a number of reasons - different markets, fuel grades, vehicle model ranges, marketing, insurance and affordability. So your vehicle may in fact be underperforming from its possible design intent in both power and for fuel economy.
