All new Mazda models from March 2012 will come with the company's new efficiency measures it calls Skyactiv.

Sixth generation Mazda products will be badged Skyactiv and it will be a offered across the entire model range, rather than on a specific model in a similar way to BMW's Efficient Dynamics.

Skyactiv models will feature new weight saving body shell technology, new gearboxes, new engines and a new chassis.

The first model launched with Skyactiv will be the CX-5 crossover SUV which will go on sale in time for the March 2012 plate change. Mazda says the CX-5 will come with a 160bhp 2.0-litre diesel with sub 120g/km of tailpipe CO2 emissions.

The new Skyactive engines will see improvements in performance and efficiency as Mazda looks to increase the environmental capabilities of its models without impacting on how fun they are to drive.

The new diesel engine will see a 20% average improvement across the range in its fuel economy and the new petrol engine will see a 15% improvement in fuel economy. Mazda says the new Skyactiv petrol engine will also have 15% more torque putting it on par with most modern diesel engines.

Jeremy Thomson, Mazda UK managing director said the Skyactiv launch will be one of the most important in the company's history.
