Koenigsegg’s Revolutionary Transmission: Unveiling the ESS

Title: Koenigsegg’s Revolutionary Transmission: Unveiling the ESS

In the realm of hypercars, Koenigsegg has consistently pushed the boundaries of automotive innovation. Their latest creation, the CC850, stands as a testament to their relentless pursuit of excellence. This remarkable vehicle pays homage to the original Koenigsegg, the CC8S, while simultaneously introducing a groundbreaking transmission system that seamlessly blends the thrill of manual driving with the convenience of an automatic gearbox.

In this comprehensive guide, we embark on a journey to unravel the intricacies of Koenigsegg’s Engaged Shifter System (ESS). We will delve into the inner workings of this revolutionary transmission, exploring its unique features, operational mechanisms, and the advantages it offers over traditional manual and automatic transmissions.

Understanding the ESS: A Paradigm Shift in Transmission Technology

Koenigsegg’s ESS represents a paradigm shift in transmission technology, offering drivers an unparalleled level of control and engagement behind the wheel. Unlike conventional automatic transmissions that rely solely on electronic control units (ECUs) to shift gears, the ESS empowers drivers with the ability to manually select gears using a traditional clutch pedal and gear shifter.

This unique combination of manual and automatic functionality sets the ESS apart from other semi-automatic or automated manual transmissions. It provides the exhilarating experience of a true manual transmission, complete with the tactile feedback of a clutch pedal and the satisfaction of rowing through gears, while also offering the convenience and ease of an automatic transmission when desired.

How Does the ESS Work? A Step-by-Step Breakdown

To fully grasp the brilliance of the ESS, let’s delve into its intricate workings step by step:

1. Engaging the Clutch:

Just like in a traditional manual transmission, the ESS requires the driver to depress the clutch pedal to disengage the engine from the transmission.

2. Selecting a Gear:

With the clutch pedal depressed, the driver can use the gear shifter to select the desired gear. The ESS features a conventional H-pattern gear pattern, providing a familiar and intuitive shifting experience.

3. Releasing the Clutch:

Once the gear is selected, the driver can gradually release the clutch pedal, allowing the engine and transmission to re-engage smoothly.

4. Automatic Shifting:

For those who prefer the convenience of an automatic transmission, the ESS offers a seamless transition to automatic mode. By simply releasing the clutch pedal without depressing it, the ESS automatically selects the appropriate gear based on the vehicle’s speed and engine RPM.

Advantages and Disadvantages of the ESS

Like any automotive innovation, the ESS comes with its own set of advantages and disadvantages:


  • Unparalleled Driver Engagement: The ESS provides drivers with the thrill of a true manual transmission, offering a heightened sense of control and connection to the vehicle.
  • Enhanced Performance: The direct mechanical connection between the driver and the transmission allows for quicker and more precise gear changes, resulting in improved acceleration and overall performance.
  • Customization and Control: The ESS empowers drivers to tailor their driving experience by selecting specific gears based on road conditions, driving style, and personal preferences.


  • Steeper Learning Curve: Mastering the ESS requires a certain level of skill and practice, especially for drivers who are accustomed to automatic transmissions.
  • Potential for Wear and Tear: The manual operation of the clutch and gears may lead to increased wear and tear over time, requiring more frequent maintenance compared to fully automatic transmissions.

Conclusion: A Game-Changer in the Hypercar Arena

Koenigsegg’s revolutionary ESS stands as a testament to the brand’s unwavering commitment to innovation and pushing the boundaries of automotive engineering. By seamlessly blending the exhilaration of a manual transmission with the convenience of an automatic gearbox, the ESS caters to a wide spectrum of driving preferences and skill levels.

As the automotive industry continues to evolve, Koenigsegg’s ESS sets a new standard for transmission technology, offering drivers an unparalleled driving experience that combines the best of both worlds.
