How does this sound?
30% more torque.
30% more power.
30% less fuel consumption.
50% less emissions.
Not bad, eh? That’s what Christian von Koenigsegg forecasts will be achievable when Cargine’s pneumatic valve technology finally takes off.
I won’t say any more for the moment. Just watch the video below. This is the 7th video of the Inside Koenigsegg Series and for the tech-heads, it’s quiet exciting.
Cargine was prominent back when Christian was leading a group trying to buy Saab Automobile in 2009. There was talk back then of the $600m EIB loan they were trying to secure being used in part to finance the further development of this system. It’s four years later and the system is still finishing development, so I’m guessing some of that EIB money would have been very welcome.
I visited Koenigsegg in 2010 and spent a wonderful day getting a look around their facility. Part of that tour included a drive in their Cargine 9-5.
The picture to the right shows the top end of the engine in the car I drove. As you can tell, it’s very different from the one you just saw in the video. Basically, if the current generation of Cargine is Windows 7 or 8, the version I got to drive was Windows 3.1. Here’s what I said about it back then:
I drove the 9-5 they had on site, pictured above with an early incarnation of the system. It’s now moved ahead since that system was fitted. The car drove extremely well, with just a little jerkiness when you lifted the throttle. This jerkiness, however, was not related to the Cargine system itself, but to the ground-up engine software they wrote (in a hurry) so that they could run the car without cams.
Removing the camshaft from the mechanical equation means energy losses are reduced, resulting in more power making it through the combustion cycle unhindered. Normal driving was very smooth, with the car easily able to carry speed in high gears with very low revs.
It was an amazing feeling to drive the future.
Christian’s allegory of playing the piano is most fitting. Instead of hitting the keyboard with a broomstick (i.e. a camshaft), engineers using Cargine will finally be able to play the instrument with their fingers. The possibilities that opens up really are mind-boggling.
