This is slightly off topic, but I can't seem to find an answer anywhere.
This Marshall Pruett article refers to the new car as the "IR12" and the current as the "IR07". But, I haven't been able to find any other references on the internet to the IR07. Everything else points to the current car being the IR05, which debuted in 2003. I can't see any difference in pictures between 2006 and 2007, but maybe it's totally under the skin? Or am I the only one who cares?
