The first international nano-car race will be held in Toulouse, France in spring 2017, with the participation of six international teams. The training session of the Dresden Team is reported using the Toulouse LT-UHV 4-STM reconfigured with four independent controllers in preparation for the race. During the training, the total Au(1 1 1) surface was prepared over the full gold substrate and a 90 nm long race track with two turns was defined according to the new nano-car race rules. The Dresden windmill molecule-vehicle was deposited in ultrahigh vacuum conditions, imaged, and manipulated by any one of the four tips on race tracks to reach a 5 nm per hour driving speed including the STM image time after a given driving bias voltage pulse. During the manipulation with one of the tips, it was possible to image with another tip in parallel. Strategies for a safe and fast driving was established by the Dresden team along the fcc rafter of the Au(1 1 1) surface together with the possibility to repair on the spot the destroyed molecule for example during the negotiation of a turn. Other teams will beneficiate from this experience to also improve their driving strategy.
