The most notable features of the new Challenger reside under hood, specifically, the 3.5-liter V-6 engine in the SE, and the 5.7-liter Hemi V-8 in the R/T. Buyers looking for the style of the Challenger, but can’t afford or don’t need the hairy-chested V-8 engines can opt for the SE. With 250 horsepower and a four-speed automatic, it won’t be the most exciting model, but it looks a lot like its brawnier stablemates. The R/T model follows the usual Dodge model lineup, slotting in above the SE but below the SRT8. With a 370 horsepower V-8 engine mated to a five-speed automatic, the R/T is no slouch.
