Yeah I've seen folks on here complianing about less mileage than that. I think all these compact cars now are tuned to maximize mileage for suburban / highway driving at the expense of true city or fast highway driving. And the Focus is no different than the rest. Just look at these reported mpg's in Motor Trends July '11 8-car comparo:
Jetta TDI: 32.3 (not a fair comparison)
Very good performance from the Focus, and that was with the Ti handling package!
