The name Charger has importance historical significance, not just to Mopar fans, but to any fan of the American muscle car. What started as a performance package on the Dart GT became the embodiment of muscle cars, the iconic fastback body and Coke-bottle shape. It bore some of the biggest, baddest engines in the Chrysler lineup, but it all started with a simple concept car based on the Dodge Polara.

CarScoop has come across an auction for this rare, one-of-a-kind concept car, which will be sold through RM Auctions.

The 1964 Dodge Charger Concept car was built, in part, to showcase Chrysler’s latest and greatest HEMI engine, the soon-to-be-famous “Elephant” 426 HEMI engine. They couldn’t drop this amazing motor into just any car in their lineup, so they developed this futuristic-looking roadster to be a vessel for the HEMI.

Like many concept cars of the time, it featured other “cutting-edge technologies” like front independent torsion bar and semi-elliptic rear leaf spring suspension, a 4:56 “Sure Grip” posi-traction rear end…and drum brakes. Really? Drum brakes?

Suffice to say, both the car, and engine, made an impact on the crowds, though when the Charger finally hit showrooms, it was not as a two-person seater, but as a fastback coupe with room for four.

The Charger Concept has been restored and received multiple awards, and as you can imagine it’s worth quite a pretty penny.

The last time it changed hands in 2007, the late John M O’Quinns paid $1.1 million. It is now being sold as his estate is auctioned off, and while the economic climate isn’t what it was in 2007, we still expect it to fetch close to $1 million. Not a bad piece to have in one’s collection.
