What does actually the ecoFLEX badge mean on vehicles by Opel?
Opel cars with this badge are powered by TWINPORT engines that are specially adapted to consume less fuel and therefore produce lower emissions. That ensures saving more fuel, and money too, but also provides a positive effect to the environment. Some of the technologies involved are variable valve timing, variable geometry inlet manifold as well as multiple dynamic fuel injection which enables optimal use of the mixture throughout the cycle, combined with close monitoring of the combustion chamber pressure.
Apart from the engine, transmission is also fine tuned to provide best possible economy and cars displaying this badge have longer gears setup and shift indicators by default. Furthermore, factory provided tyres are the ones with a very low rolling resistance. Depending on a specific vehicle, a Start/Stop mechanism could be involved, as well as the brake force regenerating which is used for charging the battery later on. Even a special efficiency monitoring system is available on some models, letting drivers know how their behaviour and driving habits affect fuel economy and closely related emissions.
