Mazda is joining the ranks of automakers exploring the use of synthetic carbon-neutral fuel. The company will be participating in this year’s ENEOS Super Taikyu Series race, and they are taking a new step in evaluating the fuel with the introduction of the Mazda CNF Concept, which will soon start competing.

The Mazda MX-5 Miata, equipped with the brand’s naturally aspirated Skyactiv-G 2.0-liter four-cylinder engine, will take part in the ST-Q class for specially developed racing vehicles from manufacturers. Toyota will also be participating in this class with the GR86 CNF concept, featuring a smaller turbocharged 1.4-liter three-cylinder engine, while Subaru will compete with the BRZ powered by a 2.4-liter flat-four engine.
