Depend on your definition of fast! If your use to driving a 3 sec machine then hop into to a 10 sec , that I consider a ton faster!
Beats me, although C&D seems to usually get slightly better times on their cars then some of the other testers. Like you said, it probably does have something to do with the weight.
Well while I'm not questioning the difference in performance between the Challenger and Prius, because it would laughable to do so. However, when I test drove the Prius after driving the Challenger for over an hour and 30 minutes to the dealer the Prius drove fine, you wouldn't really tell much difference under normal driving, but you would very much so at the drag strip. The drive back home was very reasonable and I will definitely agree this is the best Prius yet and definitely would recommend the car to anyone, including the dealer. They were great to deal with in 2013 and great again in 2016.
