VIDEO : Fans Think Robert Downey Jr. Just Revealed Iron Man's New Avengers 4 Car

Robert Downey Jr.'s Tony Stark has been known to role in top-tier style when it comes to his cars, and the actor's appearance at a recent new unveiling for Audi's E-Tron GT has Marvel fans wondering if the new model might be popping up in Avengers 4. Here's Robert Downey Jr. unveiling the new Audi E-Tron GT : Speculation that the Audi E-Tron GT will be featured in Avengers 4 comes from the fact that Marvel Studios has a history of tying luxury car brands to their film releases. They've been around the block with Audi several times now, as the car brand was featured in key scenes of Iron Man 3, Avengers: Age of Ultron, and Captain America: Civil War - most often as the personal car choice of Tony Stark.
