Now those two passions are colliding following a landmark court case that looks as if it could prevent the majority of the country?s diesel-powered cars from entering cities.

Sales of diesel-powered passenger vehicles in Deutschland are already in steep decline, but now a court has determined that towns and cities with poor air quality should prevent diesels from entering. This isn?t an entirely new thing; most German conurbations already have Umwelt (environmental) zones that bar cars incapable of passing the Euro 4 emissions test from entering them without risk of a sizable fine. But, if imposed, these new restrictions will dramatically expand that circumstance and could result in cities banning diesel cars that not only can pass both the Euro 4 and Euro 5 tests but even the latest Euro 6 emissions standards. The case was brought to the Federal Administrative Court in Leipzig by environmental group Deutsche Umwelthilfe (DUH), which sued the local authorities in Stuttgart and Dusseldorf to make them take action after air quality within their borders was found to be deficient.
