Hottest-Selling Muscle Coupes

The Chevy Camaro, Dodge Challenger and Ford Mustang are fierce competitors, and that's as true on in dealerships as it is on race tracks across America.

So far in 2015, one of the three pony car competitors has been killing its rivals, outselling the other two combined. Scroll through our gallery to find out which muscle car is the current champ where it matter most: on the sales floor.

When this fifth-generation Chevy Camaro hit the market, it was an instant sales success, outpacing its biggest rival, the Ford Mustang. Now that it's in its fifth model year – and, importantly, with a new sixth-generation Camaro being teased by GM – sales are falling.

And its sales figures bear that out. Click to the next slide to see its current sales data.
