How to surf a dune?

100 metres. That is roughly the distance that the SEAT Tarraco has to cover. It does not seem like much, but the challenge becomes more complicated when you throw in a 60 degree slope and tonnes of soft sand beneath the wheels. How do you get to the top of a mountain of sand without failing in the attempt? Stefan Ilijevic, who is responsible for Pre-development, Patents and Innovation at SEAT, gives us the keys to success.
