I recently bought a Prius C three after my 2003 Honda Civi Hybrid was totaled. Overall, i like the car, but the acceleration seems really forced. It always feels to me like the engine is really struggling at higher speeds... Like it's stuck in 3rd gear or something. I can't tell if it's just the way the car drives, or if there is something wrong. Also, i feel like i should be getting better gas mileage. If i drive it with out being super conscious of HOW i'm driving, i get 39-46 mpg on hwy/ city combo. If i use hyper miling techniques, i'm lucky to get 51 or 52, which isn't bad mileage, but i drive like a grandma in the slow lane in order to get it. Seems to me it could be better and was thinking maybe the way the engine is acting has something to do with it. It drives MUCH ROUGHER than my old HCH. Does anyone else experience this?
