There are no Porsche's in GT5 so unless this is a brand new screen and Porsche has been confirmed then it's not Gran Turismo. Then again, it definitely looks like a game. Probably a Forza 3 photomode shot of a car with the GT logo replicated in the livery editor. Or maybe it is real life.

Game shot. The colours ( particularly the curb ) are too vibrant for real life.

its a real shot i only edited the grill so it would look more like a game shot since the damage on it looked to realistic

Of course it is from GT5.

It can't be from real ife or else this wouldn't be gaming news.

Well, many guessed correctly, but it's a bit unfair if you edit the picture don't you think? :P

But anyway, that's a really nice looking car <3

for reality you need to always look for the little details that wont be in a game... it hard when it's focused like that though because those details are blured out

this photo made the real GT5 game shot photo look even more realistic... 

Wow that looks so real!!!!

Hmmm Where's the driver?
