  • Start/Stop technologies integrated across product line
  • Continuous improvements on internal combustion powertrain line-up
  • Large selection of alternative propulsion systems leads to e-mobility

Paris/Rüsselsheim. Opel stands for efficient mobility without compromising performance – at an affordable price. In times when environmental compatibility and economy are top priority, Opel’s wide range of ecoFLEX models meets the most diverse needs of drivers – regardless if they want a small car or a mid-sized wagon; a small monocab or larger people mover.

But ecoFLEX is more than just a badge; it defines Opel’s two-pronged technological approach in the global effort to improve the environment.

  • The first is the brand’s commitment to the continuous improvement of the internal combustion engine, seeking the utmost efficiency of engines running on gasoline, diesel and alternative fuels like LPG and CNG. It also includes the integration of innovations that further enhance the eco-friendliness of the vehicle – like a ‘shift up’ indicator and Start/Stop technology.
  • Starting next year, Opel will move the motoring world towards alternatives like pure electric driving, E-REV and hydrogen.

Opel ecoFLEX: Start/Stop and other technologies to reduce CO2 emission

This year, Opel has started making the Start/Stop fuel-saving technology available on ecoFLEX models. The first which have received it are the Agila 1.2 ecoFLEX 69 kW (94 hp) and the Corsa 1.3 CDTI 55 kW (75 hp). Coming soon, will be the Astra and the Meriva. By the end of next year, all Opel product lines will feature this eco-friendly technology.

The principle is simple: An engine which is not running cannot consume fuel. Instead of idling at a traffic light or train crossing, the engine stops when the driver engages the neutral gear and releases the clutch pedal. When the traffic light turns green, drivers simply press the clutch pedal to restart the engine, shift into first gear and take off. Naturally, climate comfort, steering and braking capabilities are maintained to keep occupants safe and comfortable even while the engine is temporarily off.

By eliminating idling time, engines emit less greenhouse gases and, importantly, create less noise. Naturally, owners see the greatest savings in city driving: In the urban cycle, the 55 kW (75 hp) Corsa 1.3 CDTI with Start/Stop emits 10.6 percent less CO2 than the similar version without this eco-friendly technology - or, 4.8 l/100 km, compared with 5.3 l/100 km without Start/Stop. In the combined cycle, the Corsa 1.3 CDTI with Start/Stop requires only 4.0 liters of diesel per 100 km.

Clean mobility with no compromise

In its quest to reduce fuel consumption, Opel does not compromise on performance. As proof of Opel’s continuous work improving the efficiency of its ecoFLEX family, the line-up has significantly changed in the last six months.

The new Meriva 1.3 CDTI ecoFLEX that is introduced at the Mondial de l’Automobile, for instance, combines 21 percent more power 70 kW (95 hp) with 11.2 percent lower emissions (119 g/km CO2) than its ecoFLEX predecessor.

In the new Astra range, there is a choice between diesel and gasoline-powered ecoFLEX versions. The Astra 1.3 CDTI ecoFLEX offers fuel consumption of only 4.1 liters and cuts CO2 emissions to 109 g/km. The two 1.4 ecoFLEX gasoline alternatives, with 64 kW (87 hp) and 74 kW (100 hp), both feature CO2 emissions of just 129 g/km.

In the Insignia range, the latest 2.0 CDTI ecoFLEX sedan versions also offer lower fuel consumption and CO2 emissions, reduced to 4.9 l/100 km and 129 g/km from 5.2 l/100 km and 136 g/km.

Opel continues to improve the efficiency of all its internal combustion engines and transmissions. One important step is the so-called right-sizing, whereby larger powertrains are replaced with smaller, turbo-charged engines. For instance, a brand-new 1.4 Turbo 88 kW (120 hp) with 175 Nm of torque made its world debut in the new Meriva this year, replacing the 1.6 with 105 hp from the previous generation, for a 10 percent reduction in CO2 and fuel consumption but a 15 percent increase in power.

This strategy is carried out in parallel with an increasing deployment of alternative propulsion systems, like CNG and LPG, and with technologies like Start/Stop. Opel offers one of the largest selections of CNG and LPG-powered models in Europe.

Ultimate goal: Displace oil dependency

Opel continues to strive towards its goal of lowering fuel consumption and emissions. The brand is committed to working on a range of innovations that can reduce and ultimately displace oil dependency, minimize CO2 emissions and encourage energy diversity.

To that end, the brand has set in motion a green strategy that will carry Opel forward.

This strategy includes:

• Small battery electric vehicles for people who drive short distances and for urban traffic around the world.

• Extended-range electric vehicles for families who want a car they can drive anytime, anywhere with no range anxiety. The first range-extended electric vehicle in Europe, the Opel Ampera, is scheduled to hit dealerships starting next year.

• In the long-term, hydrogen fuel cell electric vehicles for driving long distances with zero emissions and no limitation on vehicle size or function. A pioneer in fuel cell technology in Europe, Opel is road-testing a fourth generation HydroGen4 vehicle in Berlin together with 11 business partners.

Opel has a tradition of ecological advancements

In 1985 Opel was the first German automaker to include a version with a catalytic converter in each model line, and just four years later became the first manufacturer in Europe to offer all gasoline models with a three-way catalytic converter as standard.

The milestones continued, including the cD world record in 1988 with the Calibra (0.26), and the first three-liter car in the world, the Corsa Eco3, in 1995. Five years later, the Astra Eco 4, the first production four-liter car in the compact class, followed. In 2001 Opel launched the first monovalent natural-gas car, the Zafira CNG, with an engine developed specifically for operation with natural gas. The first Euro 4 diesel made its debut in 2004 in the Astra.
