It has to be said, it looks very tempting.
Their Website is here.
It also looks a bit confusing with lots of different classes of car competing - a bit like the BTCC used to be.
And what's with this "world" business - it's only in America. I know the World Series has an excuse because it was sponsored by The World newspaper but this seems to be sponsored by Cadillac - the coverage at least.
The lineup seems very impressive, especially the GT3 class:
They have Ferraris...
...and Lambos and Audis and non-European stuff too like Acuras and Caddies.
And, like the BTCC, and unlike F1, the coverage is free to watch.
So I decided to give it a go...
Never mind, BTCC starts this weekend too and it looks like another brilliant season with SEVEN champions competing.
