Car a few months ago Share Tweet Pin Share Robert Downey Jr. commissioned SpeedKore for a custom 1970 Ford Mustang worthy of Iron Man’s approval. Downey’s newest toy is a first-generation Boss 302 that was stripped down and rebuilt with carbon fiber body panels and recharged with a modern 5.0-liter V-8 engine that packs 667 horsepower. The custom job maintains the collectible’s vintage style with advanced technology, featuring an analog-style gauge cluster, three-spoke steering wheel, one-off bespoke HRE wheels and an updated interior and a unique “Tuscany” yellow paint exterior.
