Koenigsegg has shown that nothing is impossible if mechanical innovation is applied. The company’s engineers on the new Koenigsegg Jesko model achieved an incredible number of 46,000 rpm.
Jesko is powered by a 5.0-liter twin-turbocharged V8 engine with 1280 hp (955 kW) at 7800 rpm and 738 lb-ft (1,000 Nm) of torque at 2700 to 6170 rpm. Koenigsegg Jesko is one of the fastest cars in the world. Using the E85 biofuel Jesko power increases to an incredible 1600 hp (1195 kW) and 1106 lb-ft (1500 Nm) of torque. The engine is paired with a 9-speed Koenigsegg Light Speed Transmission (LST).
To achieve those numbers from standstill, it only takes 213 milliseconds, which means that it spins at a speed of 31,700 rpm. In Koenigsegg, they say that they measured higher numbers, as much as 46,000 rpm.
Koenigsegg says: “The better number you get here, the better control you get over the car, the more direct the response to your incoming request. And that means you can switch faster. Changes in gears and thus will slow down the whole process. ”
