^^Probably a R4 car. They still run against the S2000 cars in WRC. That or maybe a privateer team. I think Mads Ostberg drove a privately entered Impreza S12 in finland awhile back before he got a factory ride.
If you guys wanna see some of the older WRC cars still competing (Subaru and other's) you should watch some rallying from the Netherlands, here this will warm your heart a bit haha:
They also get used extensively in Irish tarmac rally, I can try and dig some vid up for ya later.
WRC is really only a small fragment of rallying in relative terms, but I think it is considered by most still as the "apex" of the rally world. There is still tons of amazing rally action (much of which involves Subaru's) all over the globe though, so no reason to despair haha
