When he's not occassionally saving the world as Iron Man, billionaire Tony Stark likes to enjoy the simple things in life: giant mansions, fancy gadgets, and luxury sports cars beyond reach of all but the most deep pocketed. 

If you've seen any of the "Iron Man" films, you'll know that these amazing vehicles have a tendency to appear somewhere throughout the film. They not only reinforce Stark's playboy image or provide eye candy, but also serve as gigantic marketing opportunities for automakers showing off their next-generation wares

And you can believe those opportunities for a big ticket seller like "Iron Man" come with some steep costs. For "The Avengers",  Marvel reportedly had a minimum bid of $17M for automakers interested in featuring vehicles; a score that eventually went to Acura. For "Iron Man," that price tag according to Variety was north of $10M and went to Audi.

The luxury automaker's new Audi R8 e-tron concept, which can be spotted in the new trailer for the film,  is 100% powered by electricity, has a range somewhere around 150 miles, and can go from 0-60 in less than five seconds. Oh - and if and when it sees small-scale production - will likely start at $118,000.

Of course, this isn't the first electric vehicle we've spotted in Tony Stark's garage. Back in 2008, the fledgling Tesla Motors brand scored a nice cameo in the first "Iron Man" film - a reference to Tesla founder Elon Musk. 

"Musk, 38, is a rocket scientist," wrote director Jon Favreau in a 2010 article for Time.com. "He designed the Falcon 9 booster that may serve as NASA's next vehicle to transport cargo and humans into space. He is also a green pioneer. He helped create Solar City, the largest provider of solar power systems in the U.S. And he designed the Tesla, one of the first electric cars of the modern era. Bob Lutz, the vice chairman of General Motors, credits him with catalyzing GM to move toward electric cars."

Sadly, as tends to happen in superhero films, that gorgeous R8 e-tron doesn't appear to make it to the end of the film. View the tragedy via the new "Iron Man 3" trailer below.
