Audi's robot TTS has completed a non-stop run up the legendary Pikes Peak hillclimb - without a driver. The 195kW, autonomous Audi drove to the top of the 20km, part-tar, part-dirt course, 4300m above sea level, without stopping, in 27 minutes, reaching speeds of 72km/h.

Pikes Peak race officials said an expert human driver in a similar car should be able to complete the course in about 17 minutes.
