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.

New Opel Corsa ecoFLEX with only 3.7 liter/100 km and 98g/km CO2
o 95 hp and 190 Nm of torque add driving dynamics
o Three- and five-door models seat five and yet emit less than 100g/km CO2
o Diesel Particulate Filter is standard
Rüsselsheim. Starting January 2010, the new Opel Corsa ecoFLEX is more respectful of the environment and fun to drive than ever. It is powered by a sophisticated, 70 kW/95 hp 1.3 CDTI diesel engine boosted by a turbo with a variable geometry. It is packed with 28 percent more power than the previous generation Corsa ecoFLEX even though fuel consumption and CO2 emissions are slashed by some 10 percent – yet the price is the same as the standard 90 hp Corsa 1.3 CDTI.
The new Corsa ecoFLEX illustrates Opel's philosophy of developing ecologically responsible cars that are still fun to drive. With its 190 Nm of torque available between 1750 and 3250 rpm, this Corsa ecoFLEX needs only 3.7 l/100 km, releasing just 98 g/km CO2 as a three-door. The five-door Corsa emits 99 g/km.
Both versions are equipped with a standard Diesel Particulate Filter which dramatically reduces the emissions that are the most detrimental to health. With this Corsa ecoFLEX, fleet and private drivers in many European countries may benefit from special eco tax advantages without polluting the air with diesel particulates.
Also, the new Corsa ecoFLEX can be ordered with a variety of equipment variants. This means that customers have the choice of which trim and equipment they would like in their car, from the starter level up to optimized Cosmo variant.
The engine of the new Corsa ecoFLEX combines two strengths: low CO2 and high performance. Opel engineers achieved this by using a turbo with variable turbine geometry, which significantly improves the engine's performance. To support the higher turbo pressure, engineers slightly reduced the compression ratio from 18 to 16.8: 1. Opel engineers optimized the calibration on the engine; they greatly increased low-end torque and the peak power, making a new transmission set-up possible: A longer transmission gear ratio was selected for the five-speed unit. The new 95 hp has a top speed of 177 km/h and needs only 12.3 seconds to reach 100 km/h from a standstill. This ''wide ratio, eco-friendly '' gear set work together to lower CO2 values below 100g.
Aerodynamics has been improved by lowering the car by 20 mm and optimizing the air flows via the air intakes. Wheels are fitted with newly designed, more efficient wheel caps. The Corsa ecoFLEX is equipped with special, 175/70 tires that are roll-resistance-optimized and fitted to lighter, flow formed , 14" steel wheels – 15" wheels are optional.
