Whether he's blowing stuff up as Iron Man or whipping his race car around Monaco, Tony Stark is nobody's bitch. And of course, he has excellent taste in automobiles.
We see both of those aspects of Mr. Stark in this newly-released clip from Iron Man 3, which is due out in May. Jalopnik already told you that Tony switched back to Audi after briefly experimenting with Acuras in The Avengers. We get to see more of his new electric Audi R8 E-Tron in this clip when he speeds off in it after inviting the Mandarin to come at him, bro.
I'm guessing this takes place before his fancy Malibu house gets blown up, as we've seen in other trailers. Maybe he regrets phrasing things that way.
