Mazda 3 SkyActiv-X official WLTP fuel economy, as low as 5.4L/100 km

Mazda’s ground-breaking 2.0-litre SkyActiv-X petrol engine is the first of its kind to adopt Spark Controlled Compression Ignition (SPCCI) technology which promises high output with best-in-class fuel economy.

The 2.0-litre SkyActiv-X powerplant commands a maximum output of 180 hp at 6,000 rpm and 224 Nm from a lowly 3,000 rpm in the all-new Mazda 3. It is also equipped with the Mazda M Hybrid, a 24V mild-hybrid system to further reduce fuel consumption and emissions. The engine is paired to either a 6-speed manual or automatic transmission.

Under the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) cycle, the Mazda 3 SkyActiv-X was found to return in an impressive 52.3 mpg (5.4L/100 km) and 96 grams of CO2 emissions per km. Impressive numbers for a naturally aspirated petrol engine but this is only applicable for cars running on 16-inch alloys.

For a more realistic figure, on Mazda 3s with 18-inch alloys, the WLTP rated fuel consumption is 50.4 mpg (5.6L/100 km) with 102g/km of CO2 emissions. Still pretty remarkable considering that WLTP mimics real-world driving conditions as closely as possible.

The SkyActiv-X is the result of Mazda’s dedication to keeping naturally aspirated petrol engines alive and relevant in today’s world of tightening emission regulations. With our first impressions of the (then work-in-progress) SkyActiv-X being fairly positive and now the good news of impressive WLTP fuel economy rating, the last thing to look out for is whether the SkyActiv-X engine can stand the test of time and then we’ll be sold.
