This is where the Avenger runs and hides. Sure, it looks like it would be a good friend to have in a bar fight, but once the action starts you’re left with a trio of engines that are more inclined to want to give peace a chance. The Avenger comes equipped with the base 2.4-liter four-cylinder that generates 173 horsepower. Those who want more power can upgrade to a 189-hp flex-fuel 2.7-liter V6. Both the four-cylinder and the 2.7-liter V6 are mated to a four-speed automatic. The Avenger R/T gets a 235-hp 3.5-liter V6 with 232 lb.-ft. of torque, a six-speed automatic, sport suspension and all-wheel drive.
