While most car makers are sending some sort of weird electric-powered rubbish to this year’s Pikes Peak hill climb challenge, it’s quite refreshing to see a stock production car at the event. Audi just released a teaser of a 2012 RS5, entered for the competition which is due next week. This year’s Pikes Peak was cancelled earlier due to Colorado’s massive wildfires, but it’s all set for the upcoming weekend, if everything goes according to the plan.
