Koenigsegg Agera R, 1600 - 27.02.2011

Could improve fuel efficiency by 30%

According to a recent report, Koenigsegg is developing a camless engine which is based on their twin-turbo V8.

Car & Driver says the engine will use pneumatic-controlled valves to individually regulate each cylinder. This will reportedly enable the engine to have infinitely variable valve lift and integrated cylinder deactivation technology.

Although camless designs are nothing new, there have been no viable applications in production cars using pneumatic-controlled valves. However, there is Fiat's MultiAir system which uses electro-hydraulic variable valve actuation technology on the intake side. Koenigsegg's design is reported to improve fuel efficiency by 20 to 30 percent.

In related news, the magazine says Koenigsegg is still seeking a smart airbag exemption which could enable the Agera R to be sold in the United States. Additionally, the company will reportedly unveil a rendering of their 100th vehicle at the Geneva Motor Show.

All formula 1 engines have used this technology for the last 15 years or so...that is, no "valve cams" in F1 for the last 15 years+' and they were revving upwards of 19k rpm's.

Besides more infinite ways to adjust lift you are eliminating friction with the loss of the cam/chain etc. MB has also been working on this also

Pneumatic? I would think you would need an awful lot of pressure to actuate valves pneumatically. Are they using cylinder pressure? Seems like you would have more lag in a pneumatic valve than a hydraulic one. Then again air is much lighter than hydraulic fluid, so maybe they can actually move valves faster due to less inertia?. Interesting concept.

Pneumatic valve actuation has been used since the 80's in Formula 1. Hydraulic systems would not be appropriate at all. Piezo electric and electromagnetic systems are really the future though.

So...Koenigsegg reverse engineered a fiat engine... :o

Do not invest on the airbag, invest on improving fuel efficient on a hypercar! Because that is the target of Koenigsegg customers worried about fuel efficience!

Without the airbag update or exemption, they can't legally sell the car in the US; this, is why Lotus has stopped selling cars in North America.
