GM's Opel announced it would bring a new version of Zafira minivan powered by natural gas to the Frankfurt show this year. The Zafira 1.6 CNG (Compressed Natural Gas) expands on the previous version's success (it's the best-selling natural gas vehicle in Germany, at 20,000 units produced). An underfloor arrangement of four gas tanks surround the rear axle, providing for greater interior spaciousness than its predecessor. The gassy Zafira will launch in spring 2006, but Opel will start taking orders in mid-September, when prices are announced.
