Share Download Print Dodge Challenger Blacktop October 13, 2008 , Auburn Hills, Mich. - The Dodge Challenger Blacktop Concept is a menacing creation from the minds of the Mopar Underground design team. The Dodge Challenger Blacktop began life as a 2009 Dodge Challenger R/T equipped with a 5.7-liter HEMI® V-8 and six-speed manual transmission. Mopar Underground added custom-made spoilers and front brow. To finish off the look, a black-on-black racing stripe paint scheme was added. The “in the weeds” stance and superb handling characteristics are accomplished by the Mopar coil-over suspension and strut tower brace. Blacktop rolls on massive 22-inch Dodge Viper wheels from Factory Reproductions wrapped in Dunlop tires measuring 265/35 R22 front and 305/30 R22 rear. To ensure the powertrain can keep up with the suspension, underhood performance is enhanced. The addition of Mopar components, including a cat back dual-exhaust, cold air intake, allow the HEMI V-8 to breathe easy. The interior has been enhanced with Katzkin leather seating finished in bright red plus a Mopar Kicker audio system for premium sound.
