Supercar designer Frank Stephenson who worked McLaren, Ferrari, and Maserati just to name a few, created a new car for GTA Online. He is a designer of a dozens of popular vehicles. Fans asked Stephenson to design a car for the game and he agreed.
Frank Stephenson mentioned that GTA car designs formula is simple: take two cars, mash them together, and pray like hell that you won't get sued. He however used not two vehicles, but a bunch of his favorite works.
He started the design with the base of Maserati MC12. Then he applied some details of McLaren P1, Ferrari F430, Ferrari FXX and Ford Escort.
The result
Designer named it FRNKNSTN (Frankenstein) for a good reason. The final product is certainly an interesting take on a supercar look. He however is not particularly happy with it and stated that it needs some additional work. Stephenson provided a link for 3D model for modders if they are interested to add the car to GTA. The idea to include real designers for virtual cars may be a good ad for the Rockstar Games titles.
