Opel will unveil an ecoFLEX variant emitting lower CO2 levels in each model line in Septemeber at Frankfurt Motor Show. These especially pro-environmental automobiles combine economy and driving enjoyment with low fuel consumption and reduced CO2 emissions in each vehicle class. The premiere model is a Corsa 1.3 CDTI emitting only 119 g/km of CO2, which will be launched in 2008. The Swedish premium brand Saab is also expanding its range of BioPower engines across its entire model portfolio this year. Cadillac will offer a similar E85 variant as of fall 2007, and in 2010, E85 vehicles are expected to be available for Opel/Vauxhall and Chevrolet.
