 Koenigsegg Jesko

Koenigsegg has unveiled an all-new megacar – the Koenigsegg Jesko – at the 2019 Geneva International Motor Show. Jesko inherits the mantle left by the Agera RS as the leading track-focused, road-legal car for those looking for the ultimate in vehicle performance.

  • Re-designed 5.0 litre twin-turbo V8 engine producing 1280hp on standard gasoline and 1600hp on E85 biofuel
  • Revolutionary new 9-speed Koenigsegg Light Speed Transmission (LST)
  • Advanced aerodynamics offering over 1000kg of downforce
  • Active rear-wheel steering
  • Re-designed carbon fibre chassis with more legroom, headroom and greater visibility

Jesko is named for Jesko von Koenigsegg, the father of company Founder and CEO, Christian von Koenigsegg.

Jesko von Koenigsegg was a key presence at Koenigsegg Automotive during its formative years. His considerable business acumen helped steer the company through many early challenges. Now retired and in his 80’s, Jesko von Koenigsegg and his wife, Brita, were on-hand at the 2019 Geneva Motor Show to see his namesake vehicle introduced to the world.

A New Heart

Koenigsegg’s first effort at engine development was so successful it saw the company awarded a Guinness World Record. The Koenigsegg CC8S replaced the McLaren F1 as the car with the most powerful production engine in the world.

The next Koenigsegg engine achieved a similar feat when the CCR took the world production car top speed record, again from the McLaren F1. In 2014, we announced the Koenigsegg One:1 with a twin-turbo V8 producing 1,360 hp, enough to make the One:1 the first production car in history with a 1:1 power-to-weight ratio. With 1 megawatt of power, the One:1 was the world’s first Megacar.

That record-breaking tradition continues……

Jesko – the all-new megacar from Koenigsegg – is powered by a newly designed, 1280hp (1600hp on E85), twin-turbocharged V8 engine that benefits from significant changes to the Agera engine it replaces.

At the core of the newly designed engine is the world’s lightest V8 crankshaft. Weighing just 12.5 kilos, Koenigsegg’s new flat-plane 180-degree crankshaft allows Jesko to produce more power, with greater efficiency, while achieving a higher 8500rpm rev limit.

The crankshaft is milled by small manufacturing house located in southern Sweden. It is made to Koenigsegg’s in-house design from a single solid steel billet.

The flat-plane design allows even firing across engine banks and an even more visceral engine sound. Koenigsegg has countered the tendency that flat-plane engines have towards greater vibration by designing new super-light connecting rods and pistons.

The connecting rods were designed by Koenigsegg’s engine architect, Dr. Thomas Johansson. The connecting rods are made from premium Swedish steel. At just 540g – including bolts – they’re as light as previous generations made from titanium, but even stronger.

The piston’s curved face shapes the combustion chamber in such a way so as to reduce peak pressure while maintaining high average pressure. The ceramic coating on the face of the piston prevents hot spots and detonation when the engine runs at maximum power. The piston weighs just 290 grams. Minimal weight is important because Koenigsegg engines have a very long stroke and at 8500rpm, efficiency of movement becomes critical.

 

 

 Koenigsegg Regera

 

Koenigsegg Regera

is specifically designed to be a luxury Megacar alternative to Koenigsegg’s traditional extreme, light weight, race-like road cars.

The Koenigsegg Regera combines a powerful twin-turbo V8 combustion engine with three electric motors and cutting edge battery power via new powertrain technology called Koenigsegg Direct Drive. This revolutionary technology removes the traditional gearbox, making the car lighter and more efficient.

While traditional Koenigseggs have always had surprising levels of practicality, creature comforts and features, our primary focus has always been to make the fastest cars on the planet – around a racetrack or anywhere else. The Koenigsegg Regera continues this tradition, but with innovative technology that blends outrageous speed, supreme comfort, and a unique Direct Drive experience.

The heart and soul of every Koenigsegg is its Internal Combustion Engine – the ICE. The ICE of the Regera follows the path of its siblings, the proven and extremely reliable Koenigsegg dry-sump twin turbo, DOHC, 5.0 liter V8.

The Koenigsegg V8 is the most downsized homologated production ICE in the world, with 220hp per liter (using regular pump gas). The compact nature of the engine means the Regera is light in weight, and therefore nimble and efficient.

The Regera V8 differs slightly from our predecessor Agera engine. As the powertrain already produces a combined 1500hp and with electric propulsion providing instant torque from the Direct Drive system, we did not have to go as extreme on ICE power. Instead, we installed even smaller, faster-spooling turbos on the Regera, further enhancing the car’s drivability and response.

  

 

 

  Koenigsegg Agera RS

 

TIME TO TAKE ACTION

Agera means “to take action” in Swedish. It is also short for the ancient Greek word Ageratos which means “ageless”. These are both suitable descriptors for this incredible and beautiful machine.

The CCX and CCXR were difficult cars to follow as their performance and functionality remains very competitive. Still, there is always room for change and improvement.

So Koenigsegg came up with a new interior, featuring the now famous ‘ghost’ lighting system, where all interior symbols are created with laser etched, virtually invisible nano-holes through the aluminum panels and buttons.

Furthermore, the Agera featured a unique 7 speed transmission with a E-diff and wet clutch functionality developed by Koenigsegg, a transmission that truly enhanced performance and handling.

The Agera was the first model to feature the Koenigsegg developed VGR wheels. They are real air turbines, increasing the downforce of the car by measurable amounts and improving brake cooling. All four wheels are individual so that turbine blades always face the correct direction for extraction. Given that the offset and width is different front to rear, all four wheels have their own unique design. The VGR wheels are forged and then fully machined to the final shape. All excess material is removed during the forging and machining process, thus minimizing weight whilst displaying outstanding levels of stiffness.

The CCX and CCXR both had supercharged engines, which at the time was the superior solution. However, turbo technology had come a long way and the downside of turbo lag was starting to become almost nonexistent, if engineered properly. The problem with turbo engines, high power and emission control was that the catalytic converters caused a lot of back pressure at high power levels. These back pressures were elevated through the turbo and into the exhaust ports of the engine, thereby causing what is called hot EGR. Hot EGR is a source for detonation knocking. To alleviate this problem, Christian came up with an ingenious solution by placing the pre-cat behind the waste gate instead of the turbo, thereby reducing the back pressure with a factor of 3. This simple solution gave 300 hp extra power and was a worthy successor of the Rocket cat invented and developed by Christian almost 10 years earlier. It also meant that the Agera could deliver torque, power and response to match much larger engines at a fraction of their weight, making it extremely competitive.

The Agera Became the 2010 Top Gear Hypercar of the Year.
