Opel Astra 2.0 CDTI with Start/Stop: more fuel-efficient than ever

[ahmed_7erzon]

Opel now offers the Astra 2.0 CDTI (118 kW/160 hp) with the environmentally-friendly, fuel saving ecoFLEX Technology Package, including advanced Start/Stop functionality. This package, which is fitted as an option to the 2.0 CDTI with the six-speed manual transmission, significantly lowers fuel consumption and CO₂ emissions, especially in the urban cycle: It can save up to 0.8 liters per 100 kilometers – a 13 percent reduction.
Over the combined cycle, Start/Stop reduces the Astra five-door’s average CO₂ emissions from 129 to 119 grams per kilometer, and consumption from 4.9 to 4.5 liters per 100 kilometers. To sum up, the Astra combines exceptional efficiency with high performance (118 kW/160 hp) and powerful torque (350 Nm). The Astra Sports Tourer with the ecoFLEX Technology Package is equally impressive: It now consumes 4.7 liters of diesel per 100 kilometers, rather than 5.1 liters, and produces 124 grams of CO₂ per kilometer, rather than 134 grams.

The introduction of Start/Stop in the ecoFLEX Technology Package is a further step in Opel’s ongoing efforts to reduce fuel consumption and emissions. The system has been developed in-house, and has just been launched in the new Corsa 1.3 CDTI ecoFLEX, whose 70 kW/95 hp performance comes with fuel consumption of only 3.5 liters of diesel every 100 kilometers, and emissions of just 94 grams of CO₂ per kilometer.

Start/Stop is currently available forthe Opel Agila, Corsa and Astra. By spring 2012, the company will offer 34 car/engine combinations with this technology, including all Astra diesel and gasoline models with manual transmission.





CleanTech Combustion Technology further raises efficiency

Also introduced in the 2.0 CDTI engine as part of the ecoFLEX Technology Package to further lower fuel consumption, the innovative CleanTech Combustion Technology guarantees exceptionally clean combustion and reduces enginenoise, too. This closed-loop system adjusts fuel injection to the combustion process in real time. That means the engine runs more quietly and efficiently. Furthermore, a reduced-friction camshaft bearing taps additional fuel-efficiency potential.

All manual-transmission Astra models include a shift-up indicator. The driver can actively lower fuel consumption by choosing the ideal moment to shift up as prompted on the multifunctional display.

Opel’s Start/Stop System benefits and functionality

Opel’s automatic Start/Stop system reduces the engine’s idle time and thus greenhouse-gas emissions and noise – an advantage not only for the car’s occupants, but for all road users, particularly in urban areas. Here, the principle is clear: An engine which is not running cannot consume fuel. Instead of idling at a traffic light or train crossing, the engine will automatically stop when the driver engages neutral and releases the clutch pedal (‘Autostop’ mode). When the traffic light turns green, drivers simply press the clutch pedal to restart the engine, shift into first gear and take off.

For safety reasons, and for the comfort of passengers, the temperature regulator and the brake booster vacuum control remain active in ‘Autostop’ mode. When the situation calls for it – for instance in slow, stop-start traffic – the driver can manually deactivate the system with the ‘eco’ labelled Start/Stop switch.
