Dean Rosen: The Visionary Behind Rossion

Dean Rosen was a central figure in the American component car industry. Starting as the premier distributor for Superformance Cobras, he took a bold step by acquiring the rights to the Noble M400 and re-engineering it into the Rossion Q1. He transformed a raw British track car into a refined American supercar.

The Cobra King

For enthusiasts of 1960s replicas, Dean Rosen was the go-to guy. Along with his father Ron, he ran Dynamic Motorsports in Ohio, which became the epicenter for Superformance in North America. Whether it was a GT40 or a Cobra, Rosen didn't just sell cars; he built a community. He was particularly instrumental in the success of the Superformance S-1 (a Lotus Seven derivative), championing its production when others doubted it.

Birth of the Rossion Q1

Rosen's biggest legacy began when the British manufacturer Noble ceased exporting the M400 to the US. Seeing an opportunity, Rosen and his partner Ian Grunes bought the production rights. They didn't just clone it; they evolved it. In 2007, they launched Rossion Automotive and unveiled the Rossion Q1. While the Noble was a spartan track toy, Rosen redesigned the body for better aerodynamics and overhauled the interior with luxury materials, creating a 450-hp supercar that was as comfortable on the street as it was deadly on the track.

A Life Cut Short

Dean Rosen was known for his infectious smile and his philosophy that he was "making dreams come true" rather than just moving metal. Tragically, he passed away in 2013 at the young age of 46, just as Rossion was establishing itself as a serious player in the exotic car market. His vision proved that a small American manufacturer could take a world-class chassis and make it even better.
