To achieve these figures, Opel/Vauxhall's engineers swung an army of mechanical and aero improvements into action.
First of all, the newly developed 1.3 CDTi 95-horsepower diesel engine, which recently made its debut on the 2010 Corsa, features a Diesel Particulate Filter (DPF) and re-programmed engine control settings, while the standard five-speed manual gearbox has received new ratios to optimise economy.
To better airflow around the vehicle, there's a new active aero shutter that opens to allow air past the engine at low vehicle speeds, and then automatically closes at higher speeds to smooth airflow at the front of the car.
Other improvements include re-tuned aerodynamics on the underside of the car, low resistance tires, and to help drivers take advantage of these changes, there's a gear change-up light on the instrument panel.
The new Astra ecoFLEX will be available in S, Exclusiv and SE grades, and for the first time, in a sportier SRi trim also.
