Marvel's very own

The Marvel Cinematic Universe’s Tony Stark AKA Robert Downey Jr. not only has great taste in cars, but he also has an eye for automotive quality. The 1970 Ford Mustang Boss has always been an iconic eye-catcher, and now it's a reinvigorated restomod might just be giving the original design a sign of the times pick me up. 

Hands-on restoration

Downey Jr. commissioned the shop SpeedKore to make this customized BOSS truly special and just for him. The upgraded treatment can be attributed to a mix of Ford Performance and custom carbon fiber parts. Downey Jr. has been involved throughout all of the modifications, and this model is a true blend of classic and modern.

Nice and plush

On the interior, you’ll find supple soft brown leather giving things a more “Vintage Air,” an air conditioning system, a custom steering wheel, and a vintage instrument cluster. On the outside, the BOSS is grounded on bespoke HRE wheels that have been wrapped by Michelin Pilot Super Sport Tires. All of this was put into place by Gabe’s Street Rod Custom Interiors.

New this and new that...

Underneath, the subtle yellow-painted carbon fiber panels run deep. They can be found in the valence, deep chin spoiler, quarter extensions, deck lid, bumpers, fenders, and the hood. While the exterior design has stayed true to the original, there is now Detroit Speed aluminum frame and Quadralink. As well as reinforced subframes in the front and rear. These are designed to help the car manage its intense new power.

If it ain't fast, it ain't right

The Mustang’s exhaust system comes from SpeedKore, and power is routed through a Bowler T-56 transmission, and a Detroit Speed Ford 9 inch rear differential. The car has a Ford Performance Aluminator 5.0-liter V8 with a Stage 2 Ford Performance/Roush supercharger.
