Mazda6 Diesel walked off the European stage and SkyActiv-D 2.2 is available on the opposite side of the Atlantic Ocean

Since the Dieselgate scandal that convinced Volkswagen to invest heavily in electrification, compression ignition has been seen as something of the auto industry Boogeyman. The question is, have you ever tried to imagine semi-trailers and other heavy trucks with gasoline engines, hybrid powertrains, or fully electric?

Not even the European Union has, which is slowly but steadily phasing out new fossil fuel-powered passenger cars. However, there are car manufacturers that can no longer defend diesel in this part of the world. Mazda, for example, is unplugging the 6 sedan and the SkyActiv-D 2.2 wagon.

Autocar.co.uk has no idea about if other models like the Mazda CX-5 will follow the lead, but the paint is on the wall if we take a moment to look at the CO2 emissions of a compared mild-hybrid gasoline powertrain. to a similar displacement turbodiesel.

In the case of the Mazda3 hatchback, the SkyActiv-D 1.8 has a WLTP rating of 131 grams of CO2 per kilometer, while the SkyActiv-G 2.0 M-Hybrid returns 116 grams. Get on the SkyActiv-X engine and you'll see 103 grams.

The United States is different from Europe, however, in terms of emissions regulations. Ten years after the SkyActiv-D 2.2 promise in this part of the world, Mazda confirmed to Carscoops that the inevitable had happened.

Initially scheduled to arrive in 2013 rather than 2020, the Mazda6 sedan with this engine completed its certification in the United States with the CX-5 crossover. "More information will be released in due course," the Mazda spokesman said, but what can you expect from the optional factory?

Both nameplates feature a twin-turbocharger mill, a sequential system that eliminates trade-offs between low-end response and high-end performance. A small and a large turbo guarantee up to 168 hp and 290 pound-feet (393 Nm), and Mazda designed the system for single-turbo operation, both in series and parallel compression.
