We were assuming the billionaire superhero genius will continue to have a great stable of rides in the next installment of the series, and spy photos taken on set confirm our suspicions. Robert Downey Jr. is seen driving in an Audi R8 V10 Spider during shooting of the film, which is scheduled to be released on May 7, 2010. In one of the spy photos, the V10 badging is clearly visible, confirming that Stark's drop-top R8 will be powered by VW's corporate 5.2-liter V10. With an expected 525 horsepower,the Audi R8 V10 Spider looks like our kind of Arc reactor.
