Need for Speed Film using replica supercar?

Dreamworks Studio is making a movie based on Need for Speed games. They plan to launching this movie next year, 14 March 2014.

In earlier news, Need for Speed will include many of supercar for racing scene, such as Bugatti Veyron Super Sports, Koenigsegg Agera R, Lamborghini Sesto Elemento, GTA Spano, Saleen S7 and the latest Mclaren P1.

Many movie observers think that this film will spent billion money on their budget. But how much the budget will they spent for the movie and is it worth to spent budget by buying all supercar that will be shown on the film?

Many reportage in the last week indicated that the producer actually only using a replica of the supercar. If we observed carefully, it seem clear that there was a gap between the panel in Bugatti, also the pain in Lamborghini seems not right. But are these reportage indicated the car was a replica? or not?
