The following is a press release relating to our sister entity, FreeValve AB.

Ängelholm, Sweden

The world’s first FreeValve engine intended for mass production will be driven on to the Qoros stage at the Guangzhou Motor Show in November, 2016. The ‘Qamfree’ engine will be powering a Qoros 3 hatchback that has been modified specifically for the Guangzhou show. The technology was developed by FreeValve AB, based in Ängelholm, Sweden.

Qoros debuted the Qamfree engine with FreeValve technology in a concept car at the Beijing Motor Show, in April 2016.

Called ‘Qamfree’ in the Qoros application, FreeValve uses a pneumatic-hydraulic-electronic actuator to replace the traditional camshaft-based method of controlling valve operation in an internal combustion engine. This results is much more precise and completely customizable control over valve duration and lift, on both the intake and exhaust sides.

The engine on show at Guangzhou is a 1.6 litre turbocharged engine using FreeValve technology to produce 230 horsepower and 320Nm of torque. This represents a 47% increase in power, a 45% increase in torque and a 15% reduction in fuel consumption when compared to a traditional camshaft engine with similar specifications.


The benefits are not confined to significant performance improvements and better fuel economy, however. In implementing FreeValve technology, manufacturers are able to do away with expensive parts such as the throttle body, camshaft, cam drive, timing gear and cover, wastegate, pre-catalytic converter systems and direct injection systems.

The comparative FreeValve engine is 20 kilograms lighter and much more compact, saving 50mm in height and 70mm in depth, which allows manufacturers exciting new vehicle design and packaging options.

“FreeValve technology has taken many years of testing and refinement but the results are extremely satisfying” said Urban Carlson, CEO of FreeValve AB. “This production-intent engine offers Qoros significant savings in emissions, cost and weight. It also offers groundbreaking benefits to vehicle owners in terms of a near 50% increase in both power and torque, while actually reducing fuel consumption.“

img_0079-2Christian von Koenigsegg, CEO of Koenigsegg Automotive AB and Chairman of the Board at FreeValve AB said “This move closer to mass production of FreeValve technology is also a first baby step towards the promise of important reductions in CO2 emissions. This will be boosted with the eventual widespread adoption of FreeValve technology in the automotive industry.”

This new display at Guangzhou marks the first driveable FreeValve prototype engine assembled with mass production in mind. Qoros will use a fleet of test engines in conjunction with FreeValve AB to further refine the technology to suit its own vehicles designs prior to mass production in an as-yet unnamed vehicle in the future.

    Hey Mr. Wade!

    Yes!Yes!Yes! I was waiting for this moment for quite a while now: to see Mr. Carlson’s groundbreaking FreeValve system debut on a production car! And it is no surprise for me to see Mr. von Koenigsegg wearing a big smile! I’ll bet he was waiting for quite some time now to see the technology that he and Mr. Carlson invented finally debut on a production-ready car! My congrats to you sirs!

    It is also no surprise to see the performance figures of the Qoros 3 hatchback! It’s exactly as I expected! This comes as expected, as China’s pollution levels have been on the rise, If I am correct. I have also visited the FreeValve website for a detailed analysis and will provide a link to anyone interested. All that is left now is to let this system debut on Koenigsegg’s replacement for the Agera, right Mr. Wade? I’ll be even more excited to hear that juicy bit of news!

    Congrats again! 🙂

    Yay! Now we just need Qoros to buy the rights to use the SAAB name and…

    When do Koenigsegg plan to incorporate freevalve technology in their own cars? Will that be in the next model that was mentioned recently?

      Umm….why do you want Qoros to do that Romac?

      Not sure how you eliminate the “direct injection” fuel has to come from somewhere!

      The flow of air into an engine with four valves is terrible, that’s why four valve engines have much higher spark advance (40 degrees) compared to two valve engines, typically 10-15 degrees.
      The turbulence generation mechanisms to enhance combustion speed are tumble and swirl, generating these flows consumes energy from the air flow and limit the bore to stroke ratio, as the ideal ratio for a vortex is 1:1 at bdc. It is the turbulence generated from this vortex when it collapses as the piston compresses it past a certain aspect ratio, that promotes fast combustion, a laminar flame speed of gasoline is only 3 metres per second without turbulence. As you increase the bore to stroke ratio to increase maximum engine speed, that collapse happens too early and the turbulent energy dissipates before spark ignition, this would make the valve technology suitable for low speed engines only. The reciprocating valves have mass and inertia and hot exhaust valves limit the compression ratio as they promote detonation, knocking. To get high combustion efficiency you need a high compression ratio which means the valves and piston can impact with each other, limiting the gas exchange possibilities as the piston is near top dead centre.
      Claiming you can eliminate all of the exhaust gas residuals from all of the crevice areas without being able to have the exhaust valve full open when the piston is at tdc, there is always a few percent left inside, and this helps reduce NOx emissions through reducing the combustion temperature.
      Thou I think this technology would work a lot better with something developed by an Australian while working at Mahle, the Mahle turbulent jet ignition, that technology provides multiple turbulent jets of hot gasses into the combustion chamber promoting fast combustion, reducing the need for turbulence before tdc and allowing ultra lean combustion. pushing the lean limit past a lamba of 1.4 to over 2.2 (with lpg even further) TJI has made the Mercedes(Ilmor) F1 engines far superior and more fuel efficient, why they have been unbeatable for the last few years. They Mercedes/Ilmore also had a far superior valve technology that was banned just as fully signed off engines where due to be tested in the Williams f1 cars in late 2004, thanks Renault. These engines had the Australian Bishop rotary valve, which had dual cross tumble flow structure effectively halfing the bore to stroke ratio, and as engine speed increased, the spark advance decreased. These BRV engines operated at far higher engine speeds as their were no recipricating inertial forces, and the engine weighed only 78kg verses 96 and reduced the already low f1 engines height by 50mm.

    Hi ! My name is Shreyas I’m a thriving car enthusiast with a nack for Koenigsegg cars . I live in India and I want to work for koenigsegg . The main thing that I wanted to ask is that if I wanted to work there what degree would i need ?

    Greetings from India
    Regards ,

      They have a page for jobs. You not only need a degree, you also need experience.

      Hello Shreyas B.!
      Check out the Koenigsegg work website that you can find here:
      There you will find useful information as well as a contact form to send a message to Koenigsegg HR. Christian himself (or at least an official Koenigsegg representative who is responsible for the community; I don’t know exactly if it’s really him) told me in an e-mail that that’s the way to go for this kind of questions (it says ‘job opportunities’ but I told him I wanted to ask about job opportunities and required degrees, so that will be ok):

      As far as job opportunities go, it would most likely be best if you contacted one of our representatives, via the “Work at Koenigsegg” page on the website, or visit the website.”

      I can’t tell you about the answer though, because I only wrote one message which was left unreplied either due to a technical error or because I wrote it when the whole company was still very busy (even more than now) building Agera RS’.
      I later got different job ideas (although this still remains a dream of mine) and study ideas, that’s why I didn’t try again; in case you’re wondering.

      I hope this could help you, Shreyas, I’d be very happy for you if you started working for this amazing company.

    This is cool technology, although Tucker was experimenting with this cam free technology in the 40’s, using hydraulic pressure from oil to move the valves, it was problematic then probably due to the limitations of the day.

    This is great and all, but when is Koenigsegg going to release its all electric hyper car?
