Power Ranked 2018 Acura NSX SH-AWD better.
"The Viper is heavy, ponderous, it takes a short while for momentum to build. The NSX is light and the electric motors get it moving immediately and quickly. I love how the turbos, small gas engine, relatively small batteries and electric motors all combine seamlessly to for a flawless acceleration and handling experience. The NSX is everything I want it to be."
