The classic Ford Mustang gets a modern, off-road makeover with the BorromeodeSilva STL-1. This restomod concept takes inspiration from a memorable road trip and transforms the iconic muscle car into an open-air adventure machine.
Built for the open road (and beyond), the STL-1 features a brawny new steel body designed for off-roading. Gone is the Mustang’s roof, replaced with a custom roll cage that offers the option for a removable top.
Under the hood, a powerful 444-horsepower 5.0-liter Coyote crate engine provides ample muscle, while the independent suspension and high-performance dampers ensure a smooth ride over any terrain.
BorromeodeSilva plans to build just one STL-1 for now, but depending on interest, they may create more of these head-turning machines.
