It uses a range of Mopar styling accessories for a more menacing look
While the exterior and interior feature clear cues to the original 1971 Challenger, under the long hood there's a very contemporary 485 hp 6.4-liter HEMI V8 engine, mated to a Viper Tremec T6060 six-speed transmission.
Mopar performance accessories include cold-air intake and custom dual exhaust with black powder-coated tips, while the lowered suspension brings the Shakedown Challenger closer to the ground for increased stability in corners. Adding to the mechanical upgrades is the Brembo braking system from the SRT Hellcat with six-piston front brakes and four-piston rear brakes.
Styling highlights include the "Bitchin' Black" exterior, the SRT Hellcat Slingshot-designed 19-inch front and 20-inch rear wheels, and the 1971 Shaker hood scoop. Another interesting design feature is the lack of door handles, drip rails, and fuel door, which is relocated to the trunk. The Shakedown Challenger's headlamps and taillamps are sourced from the 2017 Dodge Challenger, but modified to mesh seamlessly with '71 Challenger proportions.
Inside, the concept features Dodge Viper front seats re-trimmed in black Katzkin leather bolstered by black Alcantara inserts and red stitching, embroidered Viper steering wheel, black leather shift boot, and an SRT Hellcat gearshift knob.
The instrument panel gauges are black, in contrast with gloss carbon fiber elements such as the cluster trim, center console, steering wheel trim and door panels. Finally, the roll bar and rear seat delete mean the Shakedown Challenger should feel as well on the track as on the street.
