It used to have the 4.7? Didn't know that.. Twin turbo or supercharged?
One thought would be sometime during 2010 after the car was shown in pre-production state. Another logic time would be in May this year when the car recived its MY2013 R upgrade, makes sense since Koenigsegg almost never use the car for press or to my knowledge, private test drives either.
To me though the most logic thing is sometime between 2010-2011. I don't think they would develop a new engine without testing it in a car before putting it in production. Sure you can do dyno-testing, but it doesn't say much how the engine will interact with the rest of the car.
