LPG as a fuel has been available for petrol engines in Switzerland for a long time. It was already very common in Italy in the 1970s and has been to this day. The entire bus fleet of the Bern Public Transport Company also ran on LPG.
At first, LPG was widespread in taxis (e.g. all taxis in Zurich), and later also in the private motor vehicle sector in the 1980s in Switzerland due to favourable prices. However, due to increased taxation, it lost public interest in Switzerland again. Today, LPG is established as a fuel in some European countries and currently (since 7 July 2006), LPG (liquefied petroleum gas/autogas) has a tax reduction for use in motor vehicles in Switzerland although it was already tax exempt a few years ago.
Increased interest in Bio LPG, as well as air quality protection measures, are bringing LPG back into the spotlight because of the ease of adapting engines to use a cleaner fuel without other added problems.
There are currently 47 filling stations in Switzerland offering LPG for sale to the public, a somewhat sparse network for Switzerland's needs.
