Robert Downey Jr with Acura prototype

When the upcoming Marvel reunion The Avengers hits the silver screen, it promises to be packed with action. Action heros like Iron Man, The Incredible Hulk, Thor, Captain America... and a new Acura NSX.

Wait, what? That's right: if the latest rumors from Auto Express prove true, that mystery Acura supercar that Tony Stark (Robert Downey, Jr.) has been spied driving on the set of the upcoming superhero flick will be our first glimpse at the new supercar from Honda's premium marque.

The neo-NSX will reportedly pack the through-the-road all-wheel-drive hybrid drivetrain from the 2001 Honda Dual Note concept, encompassing a 3.5 to 3.7-liter V6 driving the rear wheels and an electric hub motor in each of the front wheels.

Tipped to be priced to take on the Nissan GT-R, the new NSX could be the Honda supercar we've been waiting for. For its part, Honda officials continue to deny that Tony Stark's car is representative of a new NSX, so we'll believe it when we see it (and we don't just mean at the movies).
