Sony just officially announced their next-gen Playstation 4 console earlier in the week. The reason why that is relevant here is because the picture you see above of the Mercedes CLA45 is not real.

Now we have two ways to be excited about this amazing car from Mercedes!The Japanese company showed several new games for the PS4 among which was Driveclub, a brand new racing franchise developed exclusively for the fourth-generation console Evolution Studios.
Two of the cars announced for the game, which offers team driving with asynchronous and real-time social gaming are the new A45 AMG that we've already seen and the CLA 45 AMG, pictured here in digital form from Driveclub. This is the first time we see what the CLA 45 AMG looks like without camouflage.
As part of the same announcement, Mercedes also confirmed that the CLA 45 AMG will celebrate its world premiere at next month's New York International Auto Show, and that it will share its 355hp (360PS) 2.0-liter turbo engine linked to a dual clutch transmission and all-wheel drive, with the A45 AMG.
