Koenigsegg camless engine and compressed air hybrid

It's not really just the lack of a cam shaft that will make this technology impressive. It is the fact that the valve timing and duration is completely under infinite computer control. The BMW engines with variable lift and no throttle are impressive. As is the Fiat multi air engine which is almost as versatile as the Koenig but only manipulates the intake cams.

Interesting - 30% better FE with 20% more power etc.
starts to look very promising.

That's the beauty of getting rid of the cam shaft. You can have the most economic valve timing profile one instant and crazy high rpm peak power the next.

I'd heard the problems with the BMW system were that it couldn't reach the same engine speeds that you could reach with a cammed system... but for roadgoing economy engines, that's not a big deal, I guess.

What's most impressive with the Koenigsegg video is that they say the test mule has already done 60,000 miles over two years. Still not a lot of miles, but that's a good sign.

I remember Porsche was developing a cam-less electromagnetic valvetrain a few years ago. It was supposed to deal better with higher revvings than a pneumatic one.

So I was totally going to post this video, and then thought "I should do a search to see if someone else posted this."

Turns out someone had. What an awesome technological innovation!

EDIT: for the lazy

Is this the car with four hundred carbon-fiber components? I watched a video on YouTube where they showed the carbon fiber valve cover!

I LOVE Koenigsegg. They are so fantastic- a true super car, McLaren F1 style.

Thank you, OP.

*60,000 kilometers

It may not be the first of its kind, but it doesn't seem like anyone else has put it in a car, and had it successfully work for over two years and almost 40k miles.

They started using modded Ford Modular engines, but then they started to develop a whole higher level of technology.

Yepp. I found them a bit before they were on Top Gear, and after seeing how impressive it was then, it's always been, in my opinion, the true epitome of a supercar company. I think of Porsche 30 years ago and how easy it was to go from having fun, to killing yourself in a car. It makes me think of that simplicity taken to an entire new level. And like you said, the engine technology- when they replaced the Ford engine they were using in the CCX to the new engine, and it's performance differences between petrol or biofuel.

I also think its amusing, their top speeds. What is it? "Oh, it goes past 240. " Well, how much faster? "We didn't bother checking the max, but it goes that fast."

(Not direct quotes, but from what I read, thats how the conversation goes )
