No doubt about the reliability and stability of this car. It's as stable on 180 as on 120.
Initially I had lil idea about this car but as days pass while I'm driving it, literally I'm lovin it. ..!!!
I'm actually very surprised by this. I've only taken my car on the highway once and vowed never to do it again. The engine is extremely underpowered for speeds greater than 110+ km/h. It's very weird because the car will be whisper-quiet at 100, or 110, but soon as I step on the gas, it all goes downhill from there. My suspicions were confirmed when I checked some Prius C forums and everyone said the same thing.
Also, the acceleration is not great. We previously had a 2007 Axio, and I know it's not comparable to a hybrid, but I'd bet that car could keep up with a manual Civic. For reference, our other car is a 1.3 City Automatic, also lacking in the acceleration department. I think the Prius would have been a better option (but it's so outdated now).
