This was released a couple of months ago, and is due to have it's 1st patch released very soon. So it's definitely worth checking out if you're interested in doing some DTM-style racing, but without the suck that's infiltrated the current DTM series.

AFAIK it's a modded rFactor engine based sim. There's already some community mods for it also on the Racedepartment.com site. It's not bad at all. Not really a fan of the 'push to block'-button style of racing. But it's got some GREAT street circuits. Plus they'll be adding some open-wheeled cars to it soon.
A bit pricey. But it's a small indie developer based in Brazil. So they're probably getting little to none financial backing for this.
