This calculator works at home... anyways it made me realize a few things.
1) The rating for the Mazda3 is ridiculous according to NRC it is 9.2 / 6.7 I get 8.5 on the highway doing 120... yes I know it's not done at 120 but still let's be realistic here. I get about 11 in the city, 10.5 if I'm lucky.
2) That's not good enough for a rebate? Wow.
