Despite the exoskeleton armor that lets him fly all the way to the stratosphere, even Ironman appreciates a good ride – the Audi R8. Audi is expected to debut its 2015 R8 Competition in the upcoming 2014 Los Angeles Auto Show, and the sleek R8 Competition is equipped with a 570hp 5.2L V10 engine, delivering a 0-100km/h time of 3.2 seconds and a top speed of 320km/h. It’s no wonder why billionaire industrialist Tony Stark, who has absolutely no shortage of exotic cars in his garage, remains faithful to his R8.
