25 years ago, Walter Rohl won the 1987 Pikes Peak International Hill Climb while driving the Audi Sport quattro S1. Fast forward to this year and the 2012 installment of the annual race in Colorado will ring nostalgic as Rohl is set to make his return race to Pikes Peak.

The car Rohl will be piloting? No other than the same 591-horsepower Audi Sport quattro S1 he raced to victory a quarter of a century ago.

In this video, Audi takes us on behind-the-scenes look at preparations being done on the Sport quattro S1 leading up to its Pikes Peak return. Fascinating is an understatement in trying to describe the video, especially when you take into account all the things that need to be done to ensure that a 25-year old race car can tackle Pikes Peak the same way it did during its lean years.

So if you have the time, spare the three minutes and change and watch the video.
