A luxury SUV with world-first technologies on an all-new platform


  • VC-Turbo: The world’s first production-ready variable compression ratio engine
  • All-new platform provides unrivalled refinement, rigidity and interior space
  • ProPILOT Assist: Intuitive technologies support the driver
  • Distinctive proportions, with INFINITI’s signature Powerful Elegance design
  • The new 2019 QX50 is the most compelling INFINITI to date. A luxury mid-size SUV with world-first technologies, stand-out design and unrivalled interior space, on an entirely new platform.


VC-Turbo – the world’s first production-ready variable compression ratio engine

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 2.0-litre VC-Turbo engine adjusts its compression ratio to optimize power and efficiency. It combines the power of a 2.0-litre turbocharged gasoline engine with the torque and efficiency of a four-cylinder diesel engine. A compelling alternative to diesel, it challenges the notion that only hybrid and diesel powertrains can deliver high torque and efficiency.

“Variable compression ratio technology represents a breakthrough in powertrain development. The QX50, powered by our VC-Turbo, is the first production vehicle ever to give drivers an engine that transforms on demand, setting a new benchmark for powertrain capability and refinement.”

Randy Parker, Vice President, INFINITI Americas

A multi-link system continuously raises or lowers the pistons’ reach to transform the compression ratio. High compression ratios aid efficiency, while low ratios enable greater power and torque. The VC-Turbo offers any compression ratio between 8:1 (for performance) and 14:1 (for efficiency), maximizing driver control.

The engine delivers 268 hp (200 kW) and 280 lbs-ft @ 1,600-4,800 RPM, an expected best-in-class combination of four-cylinder power and torque. The 2019 QX50 delivers a fuel economy of 9.0l/100. All-wheel drive models offer a 30% improvement in fuel efficiency over the previous V6 gasoline QX50.

The engine is paired with a continuously variable transmission (CVT), for seamless power delivery. Its infinite number of gears perfectly matches the engine’s ability to transform.

All-new platform with predictive, predictable ride and handling

The 2019 QX50 is built on an all-new platform, featuring a front-engine, front-wheel drive-based layout. Engineered with flexibility of application in mind, the new platform sets new standards for refinement, rigidity and interior space in the compact luxury SUV segment.

“The SUV crossover market is the number one premium segment globally. The new QX50 is INFINITI’s core model and offers premium buyers everything they could want from a vehicle of this type, thanks in part to the development of an all-new platform that is an ideal combination of roominess and packaging efficiency.”

François Bancon, Vice President, Product and Programs

The platform’s layout allows for higher levels of packaging efficiency than before, resulting in the new QX50’s ideal interior proportions for passengers and cargo.

The 2019 QX50 represents the first automotive use of SHF (Super High Formability) 980 MPa high-tensile steel, further strengthening the all-new platform. The high-tensile material can be molded into unprecedented shapes, saving weight and representing a torsional rigidity improvement of 23% over the current QX50.

New ProPILOT Assist technologies support single-lane driving

INFINITI’s customers have stated their desire to remain a key element in the driving equation, so the brand’s vision for driver assistance technologies is a step removed from the notion of fully-autonomous ‘driverless’ motoring embraced by some carmakers.

“INFINITI’s ProPILOT Assist technologies offer support when needed and add to the enjoyment and confidence of the driver. Our intention is to empower the driver and enhance feelings of pleasure behind the wheel, not to remove the driver from the equation. The brand new QX50 will set a new benchmark in the biggest premium segment.”

François Bancon, Vice President, Product and Programs

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.


Powerful exterior design, hand-crafted interior

Remaining true to the design of the QX50 Concept and QX Sport Inspiration, the QX50’s aerodynamic exterior reinterprets INFINITI’s distinctive Powerful Elegance design language and signature design cues for the SUV segment. It combines a confident stance with intelligent packaging, while deep character lines highlight the influence of human artistry in the design process.

At 1,679mm in height, the new QX50 stands out on the road. Its elevated driver position maximizes visibility, for a clear view of whether driving or parking. Aerodynamic efficiency is key to the new QX50’s design – the drag coefficient is reduced by 6% compared to the previous QX50. Its hood, bumpers, A-pillar, tailgate and enclosed underbody are all specially designed to encourage airflow over, around and under the vehicle, with minimal turbulence.

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 are designed to meet different needs of the driver and passengers.

The cabin boasts segment-leading space, with a sliding rear bench enhancing cabin and cargo flexibility and creating best-in-class rear legroom. The trunk’s volume expands from 31.6 cu ft (895 litres SAE) to 37 cu ft (1,048 litres SAE) as the rear bench slides fore and aft, growing to 60 cu ft (1,699 litres SAE) with the rear seats folded. With all seats in place, it accommodates three golf bags, or a stroller stored lengthways, with space for additional cargo. Under-floor storage areas allow owners to stow other items out of sight.
