Infiniti reveals new QX50 with groundbreaking engine tech

The luxury arm of Nissan, Infiniti, has unveiled its latest car – the QX50 SUV. A mid-sized luxury 4x4 aimed squarely at the BMW X3 and Audi Q5, the QX50 debuts many things for the brand – new styling language, new safety features, and an all-new and world-first variable compression engine.

Named VC-Turbo, the engine tech aims to combine the best aspects of both petrol and diesel cars – bringing good performance and smooth operation, but with much-improved efficiency over its equivalent conventional sibling. As the name suggests, it uses variable compression technology, which is able to alter the engine's compression ratio for performance or economy depending on demand.
