i am getting great fuel mileage already i'm in the low 40 mpg's on the freeway. But city driving i get terrible mpg's. i want to improve city mpg's. i have heard a little about DIY hybrids and i would like to know more. The 2010 Corolla S and 2010 Prius share the same gas motor, so could the corolla become a prius-like hybrid?
if there is any websites that sell parts for this type of thing i would love to know what they are. if there is any step by step processes out there i would love to see it.
the extent of my understanding is that i would need to add a large electric motor, a battery pack and a controller. i know there is much more than just that so could you guys help me?
