PRESTIGE car company Infiniti is giving fans of the brand a double-barreled peep into the automotive future.

The luxury arm of Nissan has not only unveiled what it describes as one of the most advanced internal combustion engines ever created but also a new SUV design concept.

Infiniti's new VC-Turbo, or Variable Compression Turbo, unit is the world's first production-ready variable compression ratio engine.

VC-Turbo technology combines the power of a high-performance 2.0-litre turbo petrol engine with the torque and efficiency of an advanced diesel powertrain - without the equivalent emissions.

Infiniti president Roland Krueger said: "The pioneering new VC-Turbo powertrain represents a leap forward for engine development.

"Vehicle engineers believe the breakthrough in internal combustion technology would come from mastering the variable compression ratio.

"Infiniti will be the first to bring this technology to the market in 2018. This new generation of powertrains will help our global growth and expansion of the Infiniti product portfolio."

Making its European debut at the Paris Motor Show is the Infiniti QX Sport Inspiration Concept, laying down markers for the design of future QX models.

The concept has received some design upgrades since its global reveal at the Beijing Auto Show in April and explores the brand's vision for a next-generation, mid-size premium SUV.

They are joined in Paris by the updated Q50 sports saloon, refreshed for 2017 with new design features and Infiniti's InTouch in-car technology.
