Hi all, I live in Western Washington where there are very mountainous roads and highways. For me, I have to drive 15 miles on the highway and ~5 in terrible Seattle traffic...often that traffic stops my car on the middle of steep hills INSIDE the city...there are also pretty steep hills where I live on the HWY. My question is: Can prius c's hold their own on the HWY hills/city hills? By this I mean, will my car lose mph going over the hills even if I give it a lot of juice? will my car roll backwards rapidly in the city if I stop on a hill? I want to be able to do ~70-75 without my car going all the way down to 60 over each hill. Is this possible with the power on this car? Thanks all!
