Opel has just introduced an updated version of its high-mileage, low-CO2 sub-compact Corsa. The refreshed Corsa ecoFLEX now gets 20 hp more from its 1.3-liter CDTi diesel engine than before, bringing its total to 95 hp along with 140 pound-feet of torque. Despite that boosted output, CO2 emissions drop by 10 percent making the Corsa GM's first sub-100 g/km car at just 98 g/km. The Corsa is rated at 63.6 mpg (U.S.) on the EU combined driving cycle. The ecoFLEX diesels all come equipped with particulate filters to eliminate the smoke.
The performance improvements come through the use of a new variable geometry turbocharger that allows for quicker low speed response and higher flow at maximum speed. The enhanced torque facilitated the use of longer gearing in the transaxle and lower engine speeds. The body has also been lowered by 20 mm, reducing the frontal area and drag. The new Corsa ecoFLEX goes on sale in January 2010.
