GM’s European subsidiary Opel has launched a new eco-friendly version of the subcompact Astra model with lower CO2 emissions and reduced fuel consumption thanks to a series of modifications. The most economical Astra in range which is available as a 5-door, 3-door and station wagon, comes equipped with a tweaked 1.7-liter turbo diesel engine producing CO2 emissions of 119g/km and fuel consumption of just 4.5lt /100 km or 52.3mpg US / 62.8mpg UK on the combined cycle.
Matted to a 6-speed manual gearbox, the 1.7 CDTI common-rail diesel engine has a maximum output of 110 HP, torque of 260 Nm at 2,000 rpm (192-lbs/ft) and a top speed of 188 km/h or 117mph.
To achieve these fuel consumption and CO2 emission figures, Opel’s engineers selected a longer axle ratio, optimized the engine management system and reduced the engine idle speed. In addition, the Astra ecoFLEX’s curb weight has been reduced by 30kg or 66lbs, while aerodynamics have been improved by lowering the suspension, modifying the front air intakes and fitting a drag-reducing lower engine compartment panel. Engineers also reduced the power steering pump’s idle speed and fitted low rolling-resistance 15-inch tires (16-inch optional).
