“The Jesko is more of a visceral, track-focused car, more like the Agera RS… a little bit louder, a little big lighter.”
The new Jesko by Koenigsegg, named after the company founder’s father, is claimed to be the world’s first road-legal 300 mph car. That top speed translates to more than 298 mph.
The Swedish company plans to build 125 cars, each with a 5.0-liter twin-turbo V-8 engine that, when running E85, makes 1,600 horsepower.
Jesko’s carbon fiber chassis is 40mm longer and 22mm taller than its predecessor, allowing for more head- and legroom and better rear visibility. These kinds of modern creature comforts are not typically found in superfast cars because USB ports, inductive phone charging, climate control, power seats, and parking sensors inevitably add weight. The infotainment system has a five-inch digital dashboard mounted on the steering wheel and a nine-inch central display screen.
A double-profile rear wing gives it the necessary downforce needed for a machine that the company says can break the 300mph barrier, in certain situations. The front splitter is deeper than that of the Agera and has enlarged, active under-body flaps to enhance or decrease downforce as needed.
There’s a new nine-speed transmission that allows the driver to change directly into the optimal gear for acceleration regardless of that gear’s relationship to the current gear. So, if you are in 8th gear but 5th is the optimal one for maximum acceleration, you can go directly there rather than wait for gears to sync.
Built around a redesigned 5-liter twin-turbo V8 engine, the Koenigsegg Jesko can hit 1,280 horsepower with regular gasoline or 1,600 horsepower on E85 biofuel. It has the world’s lightest crankshaft (weighing efficiently. There’s also an acoustic benefit to the new crankshaft design, which Koenigsegg says helps to produce an “even more visceral engine sound.”12.5 kilograms / 27.5 pounds), which is milled from a single billet of steel and helps the engine work more
