Mazda is developing a new powertrain for its new '3' which promises diesel efficiency from a petrol powertrain

The carmaker is currently developing the updated car which could put an end to diesel engines in its range

Powering the new car will be its SkyActiv-X unit which features Spark Controlled Compression Ignition (SCCI)

It blends both spark plugs from a conventional petrol engine and compression ignition technology from a diesel

According to Mazda, the engine will deliver 2 to 3 per cent more fuel economy than a standard engine and up to 3 per cent more torque

Mazda is also said to be focusing on improving the quality of the interior and car as a whole so it can compete with the Mercedes A Class and other similar rivals, reports AutoExpress

Its exterior design is set to be inspired by the gorgeous Kai concept which debuted at the Tokyo Motor Show 217

The car will be the first production model based on Mazda's SkyActiv Vehicle Architecture

It is a brand-new platform that is said to support a lower and more sporty seating position and incorporate the new efficient engine

"With an engine displacement of 2.L, the SKYACTIV-X delivers at least 1 percent more torque than the current SKYACTIV-G, and up to 3 percent more at certain rpms (data as of August 217, during the development process)

Previously Mazda described the benefits of the SkyActiv-X engine.It said: "In addition, because the throttle valve is open most of the time, it exhibits the superior initial acceleration response found in diesel engines which do not have a throttle valve

"On the other hand, the SKYACTIV-X spins up into the higher rpm ranges as smoothly and easily as a typical gasoline engine

"In a vehicle with a 2.L engine displacement, the SKYACTIV-X delivers a 2 percent improvement in fuel economy compared to the SKYACTIV-G, a dramatic increase

"Furthermore, in areas where low vehicle speeds are used frequently, fuel economy can be improved by up to 3 percent thanks to the use of super lean combustion

"Compared to the MZR engine of 28, fuel economy is improved a dramatic 35-4 percent, and SKYACTIV-X even equals or exceeds Mazda's latest diesel engine, SKYACTIV-D, in fuel efficiency

"With improvements being especially great in the light engine load range, this engine challenges the commonly-held belief that a large engine displacement means poor fuel economy
