After taking a hiatus for the last couple of years, the ultra-sporty Viper is back! Physically, it’s the same vehicle, with a stretched hood and truncated tail end. As before, it is powered by an 8.4L V10 that pumps 640 horsepower and 600 lbs.-ft. of torque. But this energy is now better managed with an updated platform and suspension. The Viper also scores top marks for its contemporary and comfortable cockpit.
