The Koenigsegg Jesko hypercar is a marvel of automotive engineering, boasting a high-revving twin-turbocharged 5.0-liter engine and an ultra-fast Light Speed Transmission. In a recently released video, company founder Christian von Koenigsegg provides a detailed walkthrough of the assembly process for these groundbreaking components.
The assembly of both the engine and the 9-speed transmission takes place in a pristine clean room at the company’s headquarters in Ängelholm, Sweden. Remarkably, a single person is capable of assembling one transmission or engine per week. As von Koenigsegg guides us through the process, we gain insight into the meticulous work involved in fitting intricate valves that direct transmission fluid, as well as the precise placement of shafts and bearings that hold the gears. One notable absence in the transmission assembly is the flywheel, as clutch packs close up to efficiently send power to the rear wheels.
The Jesko engine has earned a place among the world’s most powerful production engines, producing an impressive 1,600 hp on E85 fuel and 1,280 hp on pump gasoline. Notably, it is also recognized as one of the fastest revving engines. Koenigsegg showcased the engine’s remarkable capabilities by demonstrating its ability to rev from idle to 7,800 rpm in just 213 milliseconds, with a redline set at 8,500 rpm. Von Koenigsegg highlights the immense cylinder pressures generated by this level of power, underscoring the specially designed engine internals that have been developed to cope with these extreme conditions.
During the assembly process, the engine is fitted with 3D-printed Inconel exhaust headers and turbos, adding to the impressive technological features of the Jesko. Despite its turbocharged nature, von Koenigsegg reveals that the engine was intentionally designed to sound naturally aspirated, achieved through meticulous consideration of not only the exhaust system but also the placement of the turbos.
The remarkable feats of engineering found in the Koenigsegg Jesko are paving the way for the company’s future endeavors. Koenigsegg is currently undergoing a major plant expansion to accommodate the production of both the Jesko and the new Gemera, a four-seat hypercar first unveiled in 2020 with a 1,700-hp hybrid powertrain consisting of a 3-cylinder engine and a trio of electric motors. However, the company recently announced that the Gemera will also offer a V-8 hybrid powertrain, further boosting its output to an astounding 2,300 hp.
The dedication to innovation and cutting-edge technology exhibited in the Koenigsegg Jesko and the future-oriented vision of the company is sure to solidify Koenigsegg’s position as a trailblazer in the world of hypercar manufacturing. As Christian von Koenigsegg continues to push the boundaries of what is possible in automotive engineering, the automotive world eagerly anticipates the next breakthroughs to come from the visionary company.
