Koenigsegg Agera-06

Christian von Koenigsegg, founder and CEO of Koenigsegg AB revealed in an interview with Carbuzz that the company is working together with Chinese automaker Qoros to develop a small displacement engine with 400 hp.

“We are currently working on a 1.6 litre engine with Chinese carmaker Qoros that will have the potential to produce 400 hp or more. The same principles with which we designed the Agera and Regera engines can be applied to these smaller engines,” he explained.

Koenigsegg described the development as an engineering exercise to demonstrate that the brand’s technology can be applied to mass market vehicles. It has to be noted, though, that there are no plans to implant the engine into a production vehicle as of yet and it doesn’t necessarily have to produce 400 hp, as it’s intended to be a “proof of concept.”

“By reducing the bore and elongating the stroke of the piston, we are able to lessen the heat losses from the engine. We’ve also used forged pistons, forged connecting rods, and higher quality valves that make engine as efficient as possible. These are more expensive parts, but will not be so much so in mass production,” he said. With the addition of Freevalve tech, efficiency will be further increased by three to four percent.

As for Koenigsegg’s personal view on electric turbochargers that are fast becoming a subject of interest among automakers, he said, “it is interesting in many ways, but a bit clumsy, expensive, and heavy when it can be done in a simpler way.”

According to him, surging the compressor of a turbocharger with a motor will increase backpressure on the engine, which is not very good. In response, Koenigsegg is instead looking to maintain or increase a positive ratio between the intake boost and exhaust backpressure to generate as much heat as possible from combustion and into the turbo.
