They will be auctioned off as a pair — the 840 horsepower street-legal drag-strip-ready Demon, and the 645-horsepower V10 powered road-track-ready Viper. The Demon remains the most powerful production V8 car in the world; the Viper has a quarter-century legacy with more track records than any other production car. Both of the final cars will be painted in Viper Red (production code LRN).

Steve Beahm, head of Dodge, Chrysler, and Fiat North America passenger cars, pointed out that “An avid collector could search a lifetime to try to put two vehicles of this pedigree together and never find it, it’s that elusive.”

Craig Jackson, chairman and CEO of Barrett-Jackson, pointed out that the 2015 Dodge Challenger Hellcat with VIN 001 had raised $1.65 million at a benefit auction. All proceeds from this sale will go to the United Way.

2018 Dodge Challenger Demon

The 2018 Dodge Challenger SRT Demon rattled the windows with a debut at the 2017 New York International Auto Show, certified by Guinness as the world’s fastest quarter-mile production car with an NHRA-certified quarter mile time of 9.65 seconds and 140 mph. From the start, production of the Challenger SRT Demon was limited to one model year and a total of 3,300 units — 3,000 for the USA and 300 for Canada.

In addition to the Viper Red exterior color, the last production 2018 Dodge Challenger SRT Demon includes a black interior with cloth and Alcantara leather seats, a trunk carpet kit, custom car cover, badge (with VIN) for the dashboard, Demon authentication pack, and the Demon Crate with special front drag wheels, the higher-performance computer, replacement switch module, and track tools. As with all Demons, the passenger seats are not included (they are a $1 option on cars sold the normal way).

The auction will take place at the Mohegan Sun Resort in Uncasville, Connecticut, from June 20 to June 23. Selling the two cars as a package will prevent anyone from knowing which was more valuable.

The Dodge Viper was built by hand at the Conner Avenue plant, which was converted to house a large part of the-former-Chrysler’s car collection after production ended in Fall 2017. The final Viper’s red color and black interior reflect the original Dodge Viper RT/10. The car’s VIN ends in 731948; it includes exterior carbon-fiber accents, black Alcantara leather seats, and a special VIN instrument panel badge and authentication kit.
