Artist Michael Leonhard impressses us with this Plymouth Road Runner concept borrowing from the Dodge Challenger and the ’71-’72 models. We don’t want to get your hopes up though—it’s just a concept… a really fantastic concept. The car takes on an aggressive muscle car stance with 20″ front wheels and 22″ in the back. The car would likely offer the choice between a 5.7-liter, 6.1-liter or 7.0-liter engine and the option between a 6 speed automatic or manual transition. The stealth LED taillights ad a really great touch to the sleek modern twist on a classic car.
