Mated to a CVT gearbox, the 2-litre turbocharged engine produces 200kW and 380Nm and is available in front-wheel-drive and all-wheel-drive configurations.
The crucial new model debuts a new platform, and world-first variable compression engine technology, plus ProPilot semi-autonomous driving capabilities as Nissan's prestige division looks to lock horns with established prestige competitors.
Ahead of its in-the-flesh reveal at the La Auto Show, Infiniti has taken the wraps off its new mid-size luxury SUV and the ground-breaking engine technology behind it.
The Infiniti QX50 will go on sale in the United States of America in 2018, in front-wheel-drive format with all-wheel-drive as an option.
Infinit's biggest talking point is the brand's new 2.0-litre VC-Turbo engine, which is capable of varying its compression ratio for a lower rate when higher performance is required, or higher compression to benefit efficiency. All-wheel drive models are expected to be faster. The 2019 QX50 was previewed earlier this year by a concept version and from what we can see here, not much has changed. The new model, despite missing two cylinders, can offer the same power and performance but also serves up a 35% increased fuel efficiency (when the QX50 is specified with two-wheel drive).
Infiniti claims that the structure has also enabled a 23 percent improvement in torsional rigidity, reducing flex and vibrations, thus improving refinement.
Christian Meunier, Infiniti's global division vice president, said: "The QX50 is the most important vehicle we have ever launched, and it embodies everything the brand stands for: handsome design, advanced technology and empowering performance". It adopts Infiniti's latest styling language, called Powerful Elegance, with a sophisticated front end and pouncing wheel arches.
The QX50 will make its public debut at this month's LA motor show, at which time more images and technical details will be released.
