15 Most Powerful Coupes

1. 2015 Dodge Challenger

Just a little more powerful than the Mustang GT, this model comes with a 6.4 l V8 engine, one of the Chrysler’s biggest engines of this kind. There are fifteen horses more than there used to be, so now the car can develop 485 hp at 6000 rpm. You can buy both 6-speed manual and 8-speed automatic transmission versions. The new, redesigned interior makes the car comfy and great for long rides. There is plenty of space even in the back seats.
