Opel confirmed that it will feature start/stop technology on the Astra model that’s powered by the 160 hp 2.0 CDTI engine, cutting consumption levels by 13% (for the version mated to a six-speed manual transmission). When the car has this feature, the engine shuts down while idling. As a result, this model may have a substantial power output but for it to run properly, it won’t require more than 4.9 to 4.5 liters per 100 kilometers. Its CO2 emissions levels have also declined to 119 grams per kilometer of CO2 instead of 129.

Actually, the start/stop technology is just one of many features that Opel is making use of for its flagship range in order to capture the attention of customers who want to save on fuel. Under Opel’s ecoFLEX Technology Package, the start/stop is partnered with the CleanTech Combustion Technology.

This adjusts fuel injection to the combustion process in real time, by utilizing a closed-loop system. The start/stop is already used in the Agila, Corsa and Astra, but Opel has many other future plans that involve this technology. It’s expected to make its way through the lineup.[via - 4wheelsnews]
