How Koenigsegg Revolutionized the Transmission with the Direct Drive System
If you are a fan of hypercars, you probably know that Koenigsegg is one of the most innovative and ambitious manufacturers in the world. The Swedish company has been breaking records and pushing the boundaries of engineering with its creations, such as the Agera, the One:1, the Jesko, and the Gemera. But perhaps the most radical and impressive invention by Koenigsegg is the Direct Drive system, or KDD, that is used in the Regera, the world’s first “megacar”. The KDD is a patent-pending technology that replaces the traditional transmission with a hydraulic coupling and three electric motors. This means that the Regera has no gearbox, no clutch, no differential, and no fixed gear ratios. Instead, it relies on a direct connection between the engine and the rear axle, with the electric motors providing additional torque and power. The result is a smooth, seamless, and efficient acceleration from 0 to 400 km/h in less than 20 seconds. How does the KDD work? The KDD consists of four main com...
