The Dodge Challenger 1320 concept was designed with one thing in mind: drag racing. 1320 feet equals a quarter mile. The 556 HP car's been stripped of everything that won't make it go fast in a straight line.

Mopar Dodge Challenger 1320 Image Vehicle: Exploring a Street-legal Drag Pak Challenger
The Dodge Challenger 1320 began life as a Mopar Drag Pak Dodge Challenger. The current Drag Pak option is a light-weight, stripped-down, race-only, special-order version of the Dodge Challenger designed for competitive drag racing.

For the street-legal design, Mopar's design team took the vehicle back to its roots with styling reminiscent of vintage Mopar muscle, updated with today's technology. The Dodge Challenger 1320 image vehicle, named for the 1,320 feet on a quarter-mile drag strip, features Mopar's 426 cubic-inch, all-aluminum, HEMI® V-8 crate engine that generates 556 horsepower. The engine is equipped with unique Mopar-designed valve covers and a dress-up kit. Mopar's long-tube headers and exhaust system allow the cubic inches to breathe. Electric cutouts allow the exhaust to bypass the muffler system, which exits through custom side pipes for added rumble at the dragstrip. Power is put to the ground via a six-speed manual transmission through a custom Dynatrac rear housing with Mopar Dana 60 internals and a selectable, ARB locking differential. Mopar police wheels, widened in the rear, are strapped with Nitto street-legal drag radials to provide extra grip at launch. A four-corner, adjustable coil-over kit is provided by Mopar as an option for the Dodge Challenger. This system improves the handling of the vehicle under extreme loads of 556 horsepower and 540 lb.-ft. of torque.

Following Mopar's high-impact color heritage, the design team layered the 1320 in Acidic Hue, a non-metallic yellow paint and added matte black graphics. The body is lightened with the following carbon-fiber components from Mopar's design team and Seibon:

• Bulged hood with HEMI scoop
• Front spoiler
• Grille panel/headlamp surround

The interior is equipped with bare necessities-Dodge Viper seats, a sport steering wheel and a Hurst shifter. The rear seat, center console and radio have been removed in order to reduce vehicle weight and maintain the 1320's no-nonsense theme.
