Mockup vehicles pave the way for future production models, often inspired by classic vehicles, bringing them into modernity. Over the years, The Blue Oval has unveiled some bold designs that never made it to showroom floors. Take the 2005 Ford Shelby GR-1 mockup, which clearly shows that its bloodline can be traced back to the 1964 Shelby Cobra Daytona.
Ford Authority was able to check out the mockup in person during our visit to the Petersen Museum in July 2025. Interestingly, the 2005 Ford Shelby GR-1 had a rapid design timeline, going from concept to mockup in just under a year. This particular model is a fiberglass platform model, succeeding the the full-size clay rendition and preceding the working prototype.
Fiberglass allows designers to built a mockup of the vehicle to get a feel for how its bodylines and panels mesh, although it doesn’t feature an interior. It’s essentially just an exoskeleton with fake seats and a steering wheel. It’s really just for show, and, in fact, it debuted at the 2004 Pebble Beach Concours d’Elegance.
The retro-inspired design borrows heavily from the 1964 and 1965 Shelby Daytona Coupe, which itself was a model built by Carroll Shelby. The Ford Shelby GR-1 features the same long nose and the short rear end as its ancestor, right down to its unique bobtail rear end and sporty proportions.
Though this particular model doesn’t have a drivetrain or suspension, it would have borrowed heavily from the Ford GT, and would have harnessed a 605 horsepower all-aluminum V10. Simply put, it would have been one hell of a performance vehicle had it made it to production, but it just wasn’t meant to be.
The Ford Shelby GR-1 mockup is on display along a few other Blue Oval concepts, like the 1983 Ford Probe IV and the 1995 Ford GT90, the latter of which spearheaded the automaker’s “New Edge” design language.
