It's 2020 and the horsepower wars are still being fought on the streets of Detroit, with car models like the Shelby GT500 Mustang and Dodge Challenger SRT Hellcat redefining all-American muscle with their bonkers 700-plus-horsepower ratings. It's a good time to be a muscle car fan.

But both those cars feature designs that are decidedly 21st-century. What if you want modern high-power muscle in something vintage - or at the least, vintage-looking?

If you fit that description, then say hello to Six Twelve Auto Works - a New York-based custom shop that's decided to build a small run of carbon-bodied Challenger SRT Hellcats designed to look like the 1969 Dodge Charger.

Earlier in the month, we reported on one of these cars, which sold at Mecum's Kissimmee, Florida collector car auction. In fact, the idea goes farther back than that, dating to at least 2018 when Six Twelve presented its first retro-style carbon fiber Hellcat at the 2018 SEMA Show. That car, produced in partnership with Speedkore, Common Fibers, and MagnaFlow, was built as a special one-off for DJ Funkmaster Flex, and its striking vintage-inspired design attracted its share of attention.

After the success of that debut, Six Twelve decided to build a second Hellcat using a similar concept, rebodying a 2016 Hellcat as a proof-of-concept of sorts. After completion, that car fetched a cool $175,000 at Mecum's annual Harrisburg auction in 2019.

Now, Six Twelve has decided to produce a total of ten Hellcats with carbon fiber '69 Charger-inspired bodywork this year, each built to customers' specifications. The modern interior of the donor Hellcat is preserved in the course of each build, so customers don't have to say goodbye to modern creature comforts like stability control, dual-zone climate, and Uconnect infotainment.

Also untouched is the Hellcat's supercharged Hemi V8, which today puts out a heart-pounding 717 horsepower.

Pricing for Six Twelve's Hellcat-in-disguise is unknown, but likely varies depending on the level of sophistication of the requested build. Judging from the Harrisburg car's $175,000 hammer price, however, each custom-built coupe will fetch a considerable sum. Time to start saving up.
