Stupid review

General Motors' Opel division will use the IAA in Frankfurt to push its ecoFLEX initiative, which will see the automaker leverage multiple technologies to help lower its offerings' CO2 emissions and fuel consumption. Headlining ecoFLEX for the automaker is the Opel Corsa Hybrid Concept, which mates a 1.3L diesel with the next-gen Belt Alternator Starter (BAS) light hybrid system (BAS is the mild hybrid setup used in the Saturn Green Line vehicles), which trades in the current system's NiMH battery for a lithium-ion unit. The arrangement is good for a claimed fuel economy rating of 62.7 mpg (3.75 L/100km). It also emits just 99 g/km of CO2 per km.

Joining the Hybrid Concept in Frankfurt is the Corsa 1.3 CDTI ecoFLEX, which has 75 hp, boasts fuel economy of 52 mpg and CO2 emissions of 119 g/km. In addition, Opel will showcase CNG-powered vehicles, promote its "Eco-Turbo" approach to using smaller turbocharged engines that match the power of larger units but are more efficient and cleaner-running. Finally, the Vectra FlexPower will be on display, which is powered by the 175 hp E85-compatible 2.0L turbo engine used in the Saab 9-5 BioPower models.

This puts Opel in line with other European competitors, which are also actively downsizing engines and embracing biofuels, etc.
