While you can get a 2009 Challenger with either an automatic or a manual transmission, a V-6 or a V-8 engine, you can't get one with a droptop β€” and there are no plans to add one in the future, Accavitti said, even though the two-door lends itself to a droptop derivative.

"We considered a convertible when we were developing Challenger, but the extra weight needed to beef up the car when the top was removed was too much of a penalty,” he said. β€œAnd that was with a manual soft-top. A power-retractable hardtop would add even more weight."

There's an even better reason not to add the weight β€” and cost.

"We didn't see a huge market for a convertible that would justify the vehicle," he said.
