Infiniti will add a turbocharged 2.0-litre petrol engine to the Q50 saloon line-up, following the unveiling of the new model at the Guangzhou Motor Show.

The new petrol variant will be available to Chinese customers during spring 2014 before being made available in other markets.

The new four-cylinder turbo-charged engine uses direct injection with precise Piezo injectors to provide a power output of 211hp.

The engine generates 236lb-ft of torque from 1,250rpm to allow flexible and efficient driving. It's a version of an engine used in a number of Mercedes-Benz models and is provided as part of Infiniti’s collaboration agreement with Daimler AG.

During the next five years, Infiniti will increase its global vehicle portfolio by 60% and more than double the number of its powertrains.
