Auto Union Type D Silver Arrow
I spotted this racecar during my holiday in Austria. This is an Auto Union Type D which you can only find (if you are lucky enough) in a museum. This car is build in 1939 and is also known as the Silver Arrow. This Auto Union Type D was used for a promotion video of Audi. They went all the way down the mountain with this car but unfortunately it couldn't return back by its self because of some technical problems.
