Around 14 months before Euro 6d-TEMP becomes mandatory for all newly registered cars in September 2019, 79 Opel powertrains already meet the strict new limits. The future European emissions standard includes Real Driving Emissions (RDE) measured on public roads. Gasoline and LPG power units complying with Euro 6d-TEMP are available across the Opel model range—ADAM, KARL and Corsa, Astra, Cascada and Insignia, Mokka X, Crossland X, Grandland X and Zafira—plus compliant diesel versions.
The next steps are four electrified models by 2020, including the next generation Corsa as a battery electric vehicle, and the Grandland X as our first plug-in hybrid. By 2024 we will be fully electrified, with a hybrid or a battery electric version of every passenger car model.—Christian Müller, Managing Director Engineering
In addition to a variety of newly developed engines, Opel is also adding technology to current power units in order to further optimize exhaust after-treatment for Euro 6d-TEMP. The Zafira, for example, receives a new version of the 1.6-liter direct-injection gasoline engine. Consequently, all Zafira power units are now equipped with a particulate filter (including the gasoline variant), while the diesels additionally feature Selective Catalytic Reduction (SCR) technology.
Close-coupling of the Gasoline Particulate Filter (GPF) enables optimum regeneration (i.e. oxidization of the particles that accumulate in the filter), reducing particulate emissions as much as possible.
In the SCR process for diesel engines, AdBlue is injected into the exhaust gas. The solution decomposes into ammonia. Nitrogen oxides (NOx) enter the catalyst in the exhaust gas, and are then selectively reduced to nitrogen and water. With SCR and Euro 6d-TEMP compliancy, Opel’s diesel powered cars are unaffected by bans of diesel vehicles from city centers currently under discussion in Germany.
The Opel Grandland X compact sport utility vehicle (SUV) brings a new diesel to the brand’s powertrain portfolio. The new engine is designed to meet strict future emissions requirements due to an innovative oxidation catalyst/NOx adsorber coupled with Selective Catalytic Reduction (SCR).
