Koenigsegg hybrid tech
Discussion
I just read the Koenigsegg article in evo. They interview Christian Koenigsegg in it and, after having a pop at the principles of mainstream supercar hybrid tech, he mentions Koenigseggs new idea is to use a 40ltr air tank which is pressurized to 20 bar by the engine under braking.
This is apparently 'a much better solution than using heavy batteries'.
The thing is that, if I've done my maths correctly, that's a storage of about 0.24MJ. That's equivalent to about half a kilo of lithium ion batteries.
What am I missing? There's some mention in the article about using it to 'add boost' rather than driving the wheels directly. Would that make all that much difference? Have I just dropped a few powers of ten somewhere?
