The Astra engines1 prove that it is possible to balance lively performance with fuel efficiency and low emissions. Leading edge technology, leaner, greener, and packing more fun, the Opel Astra ECOTEC® engines deliver excellent performance and remarkably low fuel consumption in the compact class.

Engine range

The Astra offers a great range of diesel, petrol and LPG engines. From the base level 1.6 ECOTEC® with 85 kW (115 hp) upwards, the petrol engines offer smooth, surprisingly economical power. The 1.4 Turbo ECOTEC® with 103 kW (140 hp) offers sparkling performance, uses the smooth changing 6-speed manual transmission as well, and is optionally available with Start/Stop System.


If you prefer a 6-speed automatic transmission, you can have it with the naturally aspirated 1.6 ECOTEC® with Electric Power Steering delivering 85 kW (115 hp), or the 1.4 Turbo ECOTEC® with 103 kW (140 hp).



The diesel choice is between two 1.6 CDTI ECOTEC® versions, one with 81 kW (110 hp) or the more powerful version with 120 kW (136 hp). Both come with 6-speed manual transmission and Start/Stop System.


All engines comply with Euro 6.


ecoFLEX: saving fuel - reducing emissions

ecoFLEX is the practical way to go green. The badge on the Astra 1.6 CDTI ecoFLEX model with 81 kW (110 hp) stands for the most frugal in the Astra range. A bundle of fuel saving technologies, including Start/Stop System, active aero shutter, lower chassis and special tires, results in ultra-low consumption and emission figures.

The same technologies also make the powerful Astra 1.6 CDTI ECOTEC® with 100 kW (136 hp) and ecoFLEX Technology Pack to one of the most efficient cars in its performance class.


Start/Stop System

The Start/Stop System further optimizes fuel savings, especially in city traffic. The engine stops when the car comes to a standstill with transmission in neutral and starts instantly as soon as the clutch pedal is being activated again. The system can be activated/deactivated via a button on the instrument panel. When the system is active and the engine is stopped, the rev-counter needle goes to the labeled “AUTOSTOP” position to signal readiness for automatic start. The Start/Stop System uses an enhanced generator, starter, and a specific battery.

Control your consumption

The ECO Drive Assist shows you exactly when to shift for maximum economy, but it also does more. It shows the equipment that is using the most energy together with the fuel consumption history for the previous 50 kilometers. For this it has three sub-menus that are shown in the central display between the instruments.


Eco Index and up-shift display

The left graphic shows the current level of economy. Maximum economy is achieved when all the vertical panels are lit. The arrow shows when to shift up for maximum fuel economy.


Additional energy consumption

This shows the additional consumption for the electrical systems currently in use. The average economy is also shown.


Fuel consumption statistics

The efficiency of the driving pattern for the last 50 kilometers is shown in 5 km segments. The higher the level of the graphic elements, the higher the level of consumption, that way you can perfectly gauge you own driving efficiency.


Fuel consumption in l/km: urban 9.9–3.9, extra-urban 5.8–3.3, combined 7.3–3.6; CO2 emission in g/km: combined 172–94.


1.4 LPG: fuel consumption in l/100 km: urban 10.5–10.0 (7.9–7.6), extra-urban 6.7–6.2 (5.4–5.0), combined 8.1–7.6 (6.3–5.9); CO2 emission in g/km: combined 131–123 (146–137). LPG mode (petrol mode).
