Infiniti QX50 revealed with high-tech engine

Infiniti does stress that its system is a step removed from fully-autonomous driving technology, but shows that the challenger luxury brand is keen to keep pace with rivals.

The 2018 Infiniti QX50 has been revealed in a single image ahead of its debut at the Los Angeles motor show next week.

As for the looks, the finalised QX50 design isn't a big surprise, looking very much like a QX50 Concept that has been toned down for production. It adopts Infiniti's latest styling language, called Powerful Elegance, with a sophisticated front end and pouncing wheel arches. It's built using an industry-first SHF (Super High Formability - 980 MPa) high-tensile steel.

It is the first mass production vehicle in history to boast a variable compression ratio engine.

But when racing stops and cruising starts, the engine can alter the ratio step by step - i.e., how far down each cylinder moves in order to let in fuel before it is compressed with air and combusts to power the wheels - from a sprightly 8:1 all the way down to 14:1, in effect becoming a virtual diesel engine in terms of fuel economy and torque delivery.

In addition to the class-leading performance claim, the company says the 2.0-litre mill should improve fuel economy by 27 per cent compared to the V6. It will also debut a new interpretation of the brand's design language. This can assist with the accelerator, brakes and steering to keep the vehicle safely within a motorway lane, although Infiniti says it hasn't equipped the auto with a fully autonomous mode because its customers "have stated their desire to remain a key element in driving".

After a few days at the global motor show in Los Angeles will host the public premiere of the new crossover Infiniti QX50.

The new QX50 is 4,693 mm long and 1,903mm wide, which makes it 37 mm longer and 13 mm wider than Merc's mid-size SUV, the only one of the German trio we're familiar with (the G01 X3 and second-gen Q5 aren't here yet).
