The Avenger SXT saw some slower speeds compared to other Dodge vehicles because its tires aren’t equipped to handle much above 100 mph. You can find a used SXT with either a 2.4L four-cylinder or a 3.6L V6 engine, but the top speeds won’t vary, due to the tire rating restrictions.
Instead, these engine options offer improvements to agility with 173 horsepower on the low end and 283 horsepower on the high end in a 2012 Avenger SXT. The standard 2.4L 4-cylinder Avenger SXT has a 0-to-60 acceleration time of 8.8 seconds, but the 3.6L V6 sees that time reduced to a mere 6 seconds.
