Opel has announced plans to offer start/stop technology on the Astra ecoFLEX five-door hatchback. Details inside

Opel has announced the 2011 Astra ecoFLEX will be outfitted with a new active aero front grille shutter (which closes at high speeds to improve aerodynamics), an optimized ECU, and an improved exhaust gas recirculation module (EGR).

While these are minor updates, the big news is the addition of an optional engine start/stop system. It enables the five-door hatchback to have an average fuel consumption of 3.9 L/100 km and C02 emissions of 104 g/km. These figures are decreases of 0.2 L/km and 5 g/km compared to the standard model.

Regardless if you opt for stop/start technology, both models are powered by a 1.3-liter CDTI engine with 95 PS (75 kW / 94 hp) and 190 Nm (140 lb-ft) of torque.

Set to go on sale shortly, the Astra ecoFLEX with start/stop technology will be priced from €19,780 in Germany.
