The Grand Tour of Switzerland is the world’s first road trip for electric vehicles. A dense network with approx. 300 charging stations ensures power over the entire route and consequently guarantees comfortable and clean driving pleasure over 1600 km. The Grand Tour can take in a range of attractions, from gourmet eating in Swiss chalets and gites, to skiing and tobogganing; nature exploration to mountaineering; food to music festivals; excursions from visiting old, picturesque cities, museums and some of the most stunning architecture in Europe.
