Following the launch of the all-new Mazda 3 earlier this year, the brand is now ready to add its flagship Skyactiv-X engine to the line-up.

The new petrol powertrain is a world-first, featuring spark and compression ignition in order to provide the driveability of a powerful petrol engine and the efficiency of a diesel.

It develops 180PS and 224Nm, combined with CO2 emissions from 96g/km – making it both the most efficient and the most powerful engine in the Mazda 3 range.

Fuel economy, measured under WLTP, ranges from a combined average of 40-52mpg depending on specification and wheel size.

Mild-hybrid technology is used to help boost efficiency. The 24v system uses a small electric motor to assist the engine and recycle otherwise wasted energy during deceleration.

We drove a car with a prototype version of the engine last year, to read more click here.

The Skyactiv-X engine will be available on both the hatchback and saloon models later this year, with a choice of six-speed manual or six-speed automatic transmissions.

An all-wheel-drive system will also be available on the Mazda 3 Skyactiv-X hatchback.

Prices and full specifications are expected to be announced next month before the car goes on sale later in the year.
