Inside Design: The Awesome Chrysler SR 392 Roadster Concept:

1927 Roadster Looks & HEMI Power...

The Chrysler brand has featured a lot of concept vehicles over the brand’s 95-year history. But one concept that not a lot of people remember, let alone have heard about is the Chrysler SR 392 Roadster that made its debut at the 2007 Specialty Equipment Market Association (SEMA) Show in Las Vegas, Nevada. 

What started as the brand child of Fiat Chrysler Automobiles (FCA) designers Mark Allen (who now is the Head of Jeep® Design) and Ralph Gilles (who is of course now Head of Global Design for the company), who were then members of the company’s Mopar Underground design team which was a group of in-house automotive enthusiasts who donate their time to build special project vehicles. They required the help of Michael Chetcuti of Livonia, Michigan-based auto supplier, Quality Metalcraft (QMC), to create one of the most beautiful concepts ever from the Chrysler design studios.

The three men saw a challenge in proving that the 6.4-liter HEMI crate engine could be adapted to more than just traditional muscle cars or modified upfitted vehicles. Their idea was to redefine the classic hot rod with more industrial attitude and more urban function, that would create a distinctly “Detroit roadster”.

Allen stated in the official press release of the car, “It was important to convey the car’s theme as an homage to Detroit – the cool Detroit with its unique artistic community, music and gritty vibe. We used durable materials and let the mechanicals show to reflect the industrial backbone of the city. We wrapped it all up in a high-gloss black-and-chrome wrapper to evoke Detroit’s cool attitude.”

Thanks to QMC, who at the time designed and built stamps for the first-ever steel reproduction of a 1927 model year street rod body, designed by legendary hot rod builder, Jon Hall. It is based on Hall’s Shadowrods XL-27 Roadster.

“The core design elements of this roadster speak to the grit and industrial edge of our city,” said Chetcuti. “Things like the mezzanine flooring detail and Eames-inspired seating — these take an industrial cue but are by no means ‘rat-rod.’ It is a refined and organized design throughout.”

After several design variations were discussed, a final design was approved and QMC started to work on the reworked Shadowrods body. QMC stamped and performed the initial assembly, fabricated, and fit the revised hood, hood side panels, lower rocker panels, and doors to the body.

With an extremely low profiles stance, Shadowrods was asked to create a custom frame using a unique staggered truss concept. The car was then sent to the longtime concept and show car builder Wheel to Wheel powertrain in Madison Heights, Michigan for finishing.

Adopting the name the SR 392 Roadster, the Mopar 6.4-liter 392 cubic-inch HEMI V8 crate motor was good for 525 horsepower and 510 lb.-ft. of torque. The SR 392 Roadster harkened back to the Plymouth/Chrysler Prowler with its retro roadster appeal, but this time featured the HEMI V8 power that the Prowler lacked.
