Dutch web page, Autojunk, has posted a suspicious little spy video of a new car that is believed to be the Alfa Romeo 4C GTA Concept set to be revealed in just a couple of weeks at the Geneva Motor Show. All we've seen on the concept so far is a teaser image provided by Alfa Romeo, but if we can believe what we see in this video, then it looks like the 4C will definitely be borrowing some elements from its bigger brother, the 8C Competizione->ke1431.

The Alfa Romeo 4C will be offered in both GTA and Spider versions, and recent rumors suggest that the GTA 4C Concept will be built on the same platform as the KTM X-BOW. A four-cylinder TBi 1750 petrol engine tuned to deliver around 265 HP is also said to be fitted underneath the hood. Of course, these are all speculations at the moment, but the truth will be set free when the sheets are peeled away from the Alfa Romeo 4C GTA Concept on March 3rd, 2011.

In the meantime, check out Autojunk's spy video and let us know if you think it's real or not!
