The cam-less engine from FreeValve, a sister corporation of Koenigsegg, will prove that the technology works by driving onto the stage during Qoros’ presentation at the Guangzhou Motor Show in November 2016. It’ll be a major step towards the innovative valve-control system actually going into production.

The tech will roll onto the stage in the 1.6-liter turbocharged engine in a specially modified Qoros 3 hatchback. According to FreeValve, the powerplant produces 230 horsepower (172 kilowatts) and 236 pound-feet (320 Newton-meters) of torque. The figures reportedly equate to 47 percent more power, 45 percent more torque, and 15 percent better fuel economy than the same powerplant with a conventional valvetrain. 

“This move closer to mass production of FreeValve technology is also a first baby step towards the promise of important reductions in CO2 emissions,” said FreeValve Chairman Christian von Koenigsegg.

The video below offers a brief explanation of how the tech works. Rather than conventional rockers and camshafts, there are pneumatic-hydraulic-electronic actuators controlling the valves. FreeValve claims the results are revolutionary. An engine with it would have infinitely variable valve timing, including being able to completely shut them for cylinder deactivation.

The system also means that the engine doesn’t need any traditional timing gear and can even do away with part like the throttle body, wastegate, and direct injection systems. The changes free up a claimed 44 pounds (20 kilograms) off a powerplant and make it smaller by removing so many components.

Before the cam-less engine can actually go on sale, there’s still more testing to do. Qoros and FreeValve will now start evaluating it in fleets of vehicles, and they’ll be edging closer to actually putting an engine with this tech on sale.

FreeValve has been working on its cam-less engine since 2000. In 2012, the company even reportedly developed a prototype version using Koenigsegg’s biturbo V8. The company also displayed a concept of the system with Qoros at Auto China earlier this year.

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.“

Christian 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.
