I thought this was interesting:
Porsche 911 Carrera achieves 35mpg average fuel-economy - [2009 Porsche 911] - MotorAuthority - Car news, reviews, spy shots
Nice to see what even a 345bhp sports car can achieve when driven properly. I am sure a few of you here could easily top this. It would be fun to find out!
So- if a 345hp sports car can do 35mpg- then why can't my 175bhp '06 Corolla XRS 4-banger reach 40mpg?!?
Sounds like I need to further tweak the nut behind the wheel!
