The ecoFLEX technology lowers fuel consumption and CO2 emissions, especially in city traffic, where the Astra 2.0 CDTI hatchback can save up to 0.8 liters per 100 kilometers, equal to a 13 percent reduction over the standard model without the package.
In the combined cycle, the Astra 2.0 CDTI hatch has a rating of 4.5 liters/100 km (52.26 mpg US), 0.4 liters less than the “normal” model. CO2 emissions are also down from 129 to 119 grams per kilometer. When fitted to an Astra Sports Tourer, the ecoFLEX package lowers average fuel consumption by 0.4 liters/100 km to 4.7 liters/100 km, while also reducing CO2 emissions from 134 to 124 g/km.
Other than the Start/Stop system, the package includes the CleanTech Combustion Technology for the 2.0 CDTI unit, which promises clean combustion while also reducing engine noise by means of adjusting fuel injection to the combustion process in real time. As with the 1.3-liter ecoFLEX model, the 2.0-liter version sports an active aero shutter incorporated in the front grille and refined underbody aerodynamics.
Opel also announced that all Astra model equipped with a manual-transmission will be fitted from now on with a shift indicator showing the driver the ideal moment to change gear in order to improve fuel economy.
The ecoFLEX Technology Package for the Astra 2.0 CDTI adds €300 ($425) to the standard car's price in Germany. By spring 2012, Opel wants to offer 34 car/engine combinations with the ecoFLEX technology, including all Astra diesel and petrol models with manual transmission.
