Allpar has some interesting stuff on the 2015 Dodge Charger. They are currently expecting a mild refresh for 2015 to carry over until the big RWD Chrysler cars are completely redesigned (somewhere in the 2017 to 2020 range). Right now they are expecting a 6.2 liter Hemi pushing around 580 horsepower, updated electronics such as UConnect 2, Via Mobile and parking aids, eight-speed trannies for all motors (not just the V6 cans) and perhaps some suspension tuning. The rendering below shows some influence by the Maserati Ghibli. You can read more at Allpar
