Comedian Kevin Hart is a fan of American muscle cars, and the latest addition to his collection is a 1969 Plymouth Roadrunner restomod with 940 bhp (701 kilowatts) from a supercharged 426-cubic-inch (6.98-litre) V8. Salvaggio Design handled building the mean machine.

Hart's Roadrunner rides on a custom frame and has new parts for the floors, firewall, radiator support, wheel tubs, and boot. Inside, there's an integrated roll cage. It rides on Detroit Speed & Engineering's X-Gen 595 front suspension package integrates into the chassis.

Under the bonnet, Salvaggio describes the V8 as a hybrid between a Demon and a Hellephant engine. It has overhauled internals, including a new crank, pistons, connecting rods, camshaft, and heads. A Whipple 3.8-litre supercharger in Orange Candy satin-finish paint sits like a crown on top of the powerplant. The 940-bhp output is dyno verified.

The engine sends power to a strengthened Tremec 6060 six-speed manual transmission. The rear axle has a 3.70 gear ratio.

Hart's Roadrunner maintains the general look of the original, but there are lots of tweaks to the body. Only the roof, doors, wings/fenders, and rear quarter panels carry over from the donor car. There's a carbon-fibre bonnet with a scoop in the centre. The flush-mounted bumpers are also carbon fibre. The three-piece grille, taillight surrounds, driver door mirror, and door handles are now billet aluminium components.

To maintain the vintage appearance, there are three-piece billet hub caps that cover HRE wheels. If you look closely, it's possible to see Brembo brakes with six-piston callipers clamping on 14-inch rotors at the front and four-piston stoppers with 13-inch discs at the back.

Inside, there's a billet instrument cluster that holds Dakota Digital gauges. Black Italian leather covers the cabin, and some sections have an orange splatter effect.

To match the car, Hart also got a custom-build pair of Nike Air Max 90 sneakers, a belt, and a wallet in the same orange-splattered black leather that appears in the cabin. The shoes also have carbon-fibre pieces and aluminium Roadrunner badges.
