Based on an entirely new platform, the new QX50 is a mid-size crossover with world-first technologies, standout design and unrivalled interior space.
The VC-Turbo engine is the world’s first production-ready variable compression ratio engine, transforming on demand. A breakthrough in combustion engine design, the 2-litre VC-Turbo engine adjusts its compression ratio to optimise power and efficiency. It combines the power of a 2-litre turbocharged gasoline engine with the torque and efficiency of a 4-cylinder diesel engine. A compelling alternative to diesel, it challenges the notion that only hybrid and diesel powertrains can deliver high torque and efficiency.
A multi-link system continuously raises or lowers the pistons’ reach to transform the compression ratio. High compression ratios aid efficiency, while low compression ratios enable greater power and torque. The VC-Turbo offers any compression ratio between 8:1 (for performance) and 14:1 (for efficiency), maximising its capabilities.
The engine delivers 268hp and 380Nm, an expected best-in-class combination of 4-cylinder power and torque. The 2019 QX50 front-wheel-drive model will offer a 35% improvement in fuel efficiency over the previous V6 petrol QX50, while the all-wheel-drive model will offer a 30% improvement.
The VC-Turbo engine is paired with a continuously variable transmission (CVT), for seamless power delivery. Its infinite number of ratios perfectly matches the engine’s ability to transform.
The 2019 QX50 is built on an all-new platform, featuring a front-engine, front-drive layout. Engineered with flexibility of application in mind, the new platform sets new standards for refinement, rigidity and interior space in the compact luxury crossover segment.
In the 2019 QX50, ProPilot Assist technologies help the driver control acceleration, braking and steering during single-lane highway driving, placing them in total control. ProPilot Assist is designed to add to driving enjoyment and confidence, and is available at the push of a button.
The unrivalled interior space, artistic application of high-quality materials, and advanced craftsmanship make the cabin as welcoming and comfortable as it is flexible. Driver-centric, yet passenger-minded, the 2019 QX50 offers a package of technologies to enhance the driving experience. Its asymmetric layout and calm, connected ambience is designed to meet different needs of the driver and passengers.
