Qoros Auto unveils drivable engineering development car with QamFree engine; near +50% boost in power & torque, -15% fuel consumption
At the 2016 Guangzhou Auto Show, Qoros Auto introduced the first drivable engineering development car—a modified Qoros 3 hatchback—equipped with the QamFree engine featuring FreeValve’s Pneumatic-Hydraulic-Electric-Actuator (PHEA) technology. (Earlier post.) FreeValve AB is a sister company to Koenigsegg Automotive.
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 PHEA technology 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-liter turbocharged engine using FreeValve technology to produce 230 horsepower and 320 N·m (236 lb-ft) 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. 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 (44 lbs) 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. 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.—Urban Carlson, CEO of FreeValve AB
This demonstrator 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.
The China-based automaker also showcased the Qoros 3 Q-LECTRIQ EV concept with 350 km (217 miles), acceleration from 0-100 km/h in 7 seconds; top speed of 180 km (112 mph) and 80% fast charging within one hour, as well as the Qoros 3 GT sports crossover. Two trims of the model—equipped with a 1.6-liter turbo-charged engine paired with either a six-speed manual or a six-speed automatic transmission—are available. In another area of future mobility exploration, Qoros is partnering with a leading mobility company to develop autonomous driving applications.
