Hear The Koenigsegg Jesko Engine Make 1,614 HP On The Dyno

The Koenigsegg Jesko is an incredible hypercar that boasts a twin-turbo 5.0-liter V8 making 1,600 hp and 1,106 pound-feet of torque. To truly appreciate these great qualities, you need to see how much work is required for the Swedish automaker to create such a powerful powertrain. In this video, company boss Christian von Koenigsegg gives a factory tour, and the highlight is seeing the engine on the dyno.

Before showing what the V8 can do, Koenigsegg begins with a tour of the new environmentally controlled engine and transmission production area. It takes a worker here a week to assemble the automaker’s high-tech gearbox that holds the engine starter and flywheel yet weighs 198 pounds (90 kg).

The Jesko engine is an equally high-tech item. As a transmission, it takes one worker per week to produce one unit, and there are three assembly stations. Von Koenigsegg prides itself on forged pistols because they feature the brand’s shield logo in the center of the combustion area. Another nice touch is that the company 3D prints a heat-resistant Inconel alloy to create the exhaust components before welding them together.

The first dyno run shows the V8 engine running on E85 gasoline. The powerplant creates a wall of noise, and the graph shows that it has 1,614 horsepower and 1,174 foot-pounds of torque (1,591.3 Newton meters), which is slightly higher than the factory rating.

The second run uses E10 95-octane fuel, which von Koenigsegg says is equivalent to 91-octane gasoline in the United States. The brand recommends using 93 octane but tunes to lower quality gas to provide a margin of safety. This time, the V8 produces 1,289 hp and 933.8 lb-ft (1,266 Nm)

Koenigsegg is only making 125 Jeskos, and all of them already have buyers. The hypercar starts at $2.85 million. The company delivered the first to a customer on May 31, 2023.

The brand is also working on Jesko Absolut with the goal of exceeding 300 miles per hour. Computer simulations suggest the thin body could allow the car to reach 330 mph, but no real-world tests confirm that.
