Robert Downey, Jr.’s SpeedKore 1974 BMW 3.0 CS Coupe

At this point, it’s impossible to deny the fact that Wisconsin-based SpeedKore makes anything but the best American muscle on the market. Case in point–their 1970 Dodge Charger, 1970 Dodge Charger Tantrum or Robert Downey Jr.’s 1970 Ford Boss 302 Mustang. If you want American muscle, built for the future with modern performance, there’s no better option than SpeedKore. RDJ was so impressed with that Ford Boss Mustang that he came back to have them custom build the best, one-of-a-kind 1974 BMW 3.0 CS Coupe that the world has ever seen. The steel-bodied European hot rod was outfitted with extensive body repairs, custom carbon fiber pieces, hydro-dipped woodgrain trim, and new upgrades like a Nardi steering wheel, Classic Instruments gauge cluster, rear spoiler, and, of course, an engine swap. In this particular vehicle, SpeedKore swapped out the original carbureted inline-six for a 3.6-liter, fuel-injected S38 from an E34 M5 that produces around 311 horsepower. Pair that modern performance with the updated, vintage styling and you have a recipe for success however you look at it.
