Not bothered about the obvious topic that's going on. However, that Prodrive P2 was lovely. Shame it's not going to make it into production.

Went onto the BBC website to find out more & there's a pretty simple explanation of how the anti-lag works. I knew the reasons behind it, but never knew what went on. Now I know why it spits flames!

Also an expanation of how the electronic diffs work.
