Mazda recently announced plans for a high-tech Skyactiv-X engine and the company has already begun testing prototypes with the new powertrain.

Set to debut in the new Mazda3, the 2.0-liter Skyactiv-X engine will seek to combine the best attributes of gasoline and diesel engines. This is possible thanks to Spark Controlled Compression Ignition (SCCI) technology which ignites the fuel-air mixture similar to a diesel engine.

The system will help to improve fuel efficiency without the usual drawbacks of diesel engines. Mazda hasn’t finalized the numbers but the company has previously said the engine is 20 to 30 percent more efficient than current Skyactiv-G engines with the same displacement.

Despite the focus on efficiency, performance hasn’t been forgotten. The engines will come equipped with a supercharger that promises to deliver 10 to 30 percent more torque than the company’s current powertrain.

Getting back to the prototype itself, the mule doesn’t reveal much but the rear fenders are slightly wider and the area around the fuel cap has been modified.

The next Mazda3 is expected to be previewed by a concept at the Tokyo Motor Show in October. Reports have suggested the production model will ride on the same platform as today’s car but sport all-new body work and possibly an upgraded interior.
