In the past two installments of Iron Man, Robert Downey Jr., aka Tony Stark, never hid his affinity for the Audi R8->ke1440.

But thanks to Marvel Studio's recent partnership with Acura->ke10, it looks like our favorite billionaire playboy is turning over his Audi digs for an Acura sports car that, quite frankly, we've never seen before.

Acura began appearing in Thor and Captain America as S.H.I.E.L.D.'s official official chose of brand. With the collaboration movie - the Avenges - currently filming in New York, it appears that Acura has allowed the studio to use a mysterious car that has yet been given any information on.

When asked by Autoblog about the matter, the automaker responded that the mystery car is a one-off make that's neither a concept nor a production model.

"The open-top sports car that was photographed yesterday is a one-off, fictional car that was made just for the movie and will not be produced," Acura's Gary Robinson said.

Judging from the looks of the car, it does remind us a little bit of the R8 in terms of its overall shape. And to be honest about it, we certainly wouldn't mind seeing this car in concept guise. Better yet, let's have it built for production!
