Powerful Elegance design language, Distinctive proportions and signature details set the 2019 INFINITI QX50 apart
Designed to perform: Elevated, dynamic proportions and deep character lines
The 2019 INFINITI QX50 is defined by distinctive proportions, which set the car apart from its competitors. Influenced by INFINITI's Powerful Elegance design language, the all-2019 QX50 has an elevated, commanding crossover stance and strong character lines.
At an overall height of 66.1 in., the volume of the 2019 INFINITI QX50's body creates a striking presence and helps the vehicle stand out on the road. The elevated driver position maximizes visibility, with an eye-point 50.7 in. in height affording a clear view whether driving or parking.
The all-new 2019 INFINITI QX50's striking visual character adjoins a clamshell hood, presenting a strong degree of muscularity while retaining balanced body proportions. The visually long hood – together with sculpted surface and detailing – create a feeling of flowing power.
The unique hood shape facilitates enhanced cabin proportions. A newly developed bonnet hinge system, Pop-Up 4 Link Hinge, has been created especially for the INFINITI QX50, allowing deep, sharp-edged character lines to flow from the hood along the body. Integrating the A-pillar into this shape also makes the hood appear longer.
Character lines are formed by sharp, rolled-edge creases in the bodywork, achieved with INFINITI's own deep-sculpting manufacturing methods. The clamshell hood flows into the character lines running along the side of the vehicle, creating an angle sharper than most competitors, and providing the 2019 INFINITI QX50 with a distinctive visual signature.
The deep-stamping production methods behind the 2019 INFINITI QX50's bodywork enable the creation of an integrated door design. This results in an almost-seamless connection between the door glass and metal. Integrated door handles allow the deep character line to continue uninterrupted along the side of the car.
The all-new 2019 INFINITI QX50's sophisticated rear aspect is characterized by clean, simple lines, and curves that release the visual energy built up from character lines flowing along the car's sides. A chrome-tipped dual exhaust sits within the rear lower bumper.
The 2019 INFINITI QX50's commanding stance adds to its sense of agility and crossover-like ruggedness. Designed to look large in relation to the rest of the car, customers will be able to choose from 19-in. or 20-in. wheels.
Aerodynamic efficiency is key to the all-new 2019 INFINITI QX50's design – the drag coefficient is improved by 6 % compared to the previous-generation QX50. Its hood, A-pillar, tailgate and enclosed underbody are all specially designed to encourage airflow over, around and under the vehicle, with minimal turbulence. The bumpers and wheel arches feature air slits, inlets and outlets to assist the efficient flow of air.
Meanwhile, the center of the all-new 2019 INFINITI QX50's roof is subtly recessed towards the rear of the car, and the side spoiler and a defined trailing edge to the rear combination lamps each contribute towards a zero lift design, encouraging the expulsion of air tumbling down from the top of the car when in motion. INFINITI's approach to aerodynamic efficiency aids stability and maximizes fuel efficiency.
Clear sense of human artistry combined with premium-quality materials and manufacture
Like its stablemates in the INFINITI range, the all-new QX50 2019 conveys a clear sense of human artistry – where the lines and forms are organic, natural and artistic in expression.
INFINITI seeks to design concepts with production intent, exhibited in previous true-to-concept production versions of the QX30, QX80 and Q60. The 2019 INFINITI QX50 is the latest vehicle to remain true to this form.
The all-new 2019 INFINITI QX50 remains true to the QX50 Concept, which inspired the vehicle's standout design. With this concept, INFINITI explored a more emotional execution of crossover design, bringing a degree of artistry to a segment typified by an uninspiring and clinical aesthetic.

Unmistakable signatures: Powerful Elegance design language and signature design cues make the 2019 INFINITI QX50 instantly recognizable as a modern INFINITI
The 2019 QX50 features INFINITI's Powerful Elegance design language – characterized by flowing sculptural lines and strong, muscular proportions – endowing the 2019 QX50 with a purposeful aura, while hinting at its dynamic capabilities.
INFINITI's signature LED headlights emulate the human eye in their appearance, alluring and intense when seen at a glance. Emulating the eyebrow, the horizontal light signature cuts across the projector to make a visual statement, similar in execution to the headlamps from the INFINITI Q60 sports coupe. Advanced headlight technology lights up the road ahead, from every angle. Light guide technology uses a series of reflective channels to disperse light from the LED accents, spreading light evenly.
At the rear of the 2019 INFINITI QX50, the design of the LED taillights matches the shape of the front lamps. The rear light design connects visually to the chrome tailgate strip and runs into the sides of the all-new QX50 2019, creating an uninterrupted visual line flowing from the front to the rear of the car.
INFINITI's signature crescent-cut D-pillar extends the visual length of the roof line, and the rear pillar arcs forward, emphasizing motion even when the car is stationary – demonstrating INFINITI's commitment to bringing distinctive design to life.
A quality, hand-crafted feel inside
Specialty trim and color combinations allow for personal expression inside the 2019 INFINITI QX50. Interior package options give customers a choice of trim colors and materials. Colors include Black, Dark Blue, Mid Brown and White, with each used across a variety of surfaces, from the center console leather to other parts of the trim. Smooth leather or quilting is used for seats, with open-pore wood or aluminum adorning the dashboard, while the customer's preferred color options are evident throughout the cabin.
Using bespoke manufacturing methods, wrap-and-sew detailing is a highlight of the hand-crafted ambience. The leather on the dash is selected for its quality and is hand-wrapped over the edges of the panels. The seats, door panels and dashboard feature a laser hole-cut stitch pattern specifically tailored to follow the curves of the interior surfaces. Contrast color stitching is used on the seats, paired with 3millimeter piping for a luxury look and feel.
Even items that are typically complicated to manufacture, such as the instrument panel's wave form, use wrap and sew production methods. The skin of these interior elements has been curated by the human hand, combining leather and synthetic materials.
Where many luxury vehicle interiors use high-gloss wood surfaces to create the % of quality, the all-new 2019 INFINITI QX50 is finished in genuine, matt-finish open-pore maple wood. The wood is treated to retain its natural characteristics in texture and appearance. Running a hand over it, the grain of the wood is still detectable to the touch, demonstrating a high level of craftsmanship to create an authentic, modern and highly tactile dashboard.
The all-new 2019 INFINITI QX50 is powered by VC-Turbo, the world's first production-ready variable compression ratio engine
INFINITI's VC-Turbo engine is the world's first production-ready variable compression ratio engine – and it makes its production debut on the new 2019 QX50. This unique variable compression technology represents a breakthrough in combustion engine design – the all-2019 INFINITI QX50's 2.0L VC-Turbo continually transforms, adjusting its compression ratio to optimize power and fuel efficiency. It combines the power of a 2.0L turbocharged gasoline engine with the torque and efficiency of an advanced four-cylinder diesel engine.
The blend of performance and efficiency represents a compelling alternative to diesel, challenging the notion that only hybrid and diesel powertrains are capable of delivering high torque and efficiency. The engine delivers 268 hp 5,600 rpm and 280 lb ft 4,400 rpm. The VC-Turbo's specific power output is higher than many competing turbocharged gasoline engines, and comes close to the performance of some V6 gasoline engines. The unit's single-scroll turbo ensures immediate accelerator responses, on demand.
Equipped with the VC-Turbo engine, the 2019 INFINITI QX50 is competitively efficient, expected to deliver gasoline fuel economy of 27 mpg. In front-wheel drive specification, this offers a 35 % improvement in fuel efficiency over the V6 gasoline engine in the previous QX50, while the new all-wheel drive model's 26 mpg represents a 30 % improvement.
Other highlights include compact packaging and weight-saving technologies. The engine block and cylinder head are cast in lightweight aluminum alloy, while the transformative multi-link components are manufactured in high-carbon steel alloy. Compared to INFINITI's 3.5L VQ V6 engine, the 2.0L VC-Turbo weighs 18 kilograms less and requires less space in the engine bay.
The engine employs the world's first multi-link system and an electric motor with a unique Harmonic Drive reduction gear to transform its compression ratio. The electric motor is connected to the Harmonic Drive with a control arm; as the Harmonic Drive rotates, the control shaft at the base of the engine rotates, moving the multi-link system within the engine. As the angle of the multi-link arms changes, it adjusts the top-dead-center position of the pistons – and the compression ratio with them. An eccentric control shaft changes the compression ratio of all the cylinders at the same time. As a result, the engine capacity varies between 1,997 cc and 1,970 cc.
The engine switches between both at regular engine speeds, with both sets of injectors able to work in conjunction under higher loads.
The VC-Turbo is also smoother than conventional in-line engines, and has the low noise and vibration levels expected of a traditional V6. This is, in part, a result of its multi-link design, where the piston connecting rods are almost vertical during the combustion cycle. This represents the ideal reciprocating motion, and entirely negates the need for balance shafts. Despite the addition of a multi-link layout, the engine is therefore as compact as a conventional 2.0L four-cylinder engine.
Technology: ProPILOT Assist driver support and in-car connectivity
A unique perspective on how the driver's relationship with the car could evolve
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 allows drivers to retain ultimate control over their vehicle. These technologies empower and give confidence to the driver, including the ability to navigate stop-start traffic on the highway by monitoring the position of vehicles in front of the all-new 2019 INFINITI QX50.
ProPILOT is the umbrella term under which all future INFINITI driver assist technologies will be based and represents the first step in their development. These technologies are designed to support the driver in identifying and responding to other road users and potential hazards. Drawing on inputs from radar and camera to read the road ahead and monitor the position of vehicles in front, the system allows the car to react accordingly. The framework that underpins ProPILOT will be developed in the future with a series of new functionalities.
New ProPILOT Assist technologies support single-lane driving
The suite of driver assist technologies in the all-new 2019 INFINITI QX50 is called ProPILOT Assist, which, as a package, helps the driver control acceleration, braking and steering during single-lane highway driving. Equipped for the first time in an INFINITI model, ProPILOT Assist effectively helps to reduce the stress of stop-and-go driving and highway cruises. ProPILOT Assist takes over single-lane driving operation at the push of a button, without the driver's input on acceleration, braking, or steering. The driver can choose to let the car operate on their behalf in stop-start traffic.
The technologies that make up the full suite of INFINITI QX50's ProPILOT Assist system include Direct Adaptive Steering and Intelligent Cruise Control. These are supported by additional technologies, including: Distance Control Assist; Back-up Collision Intervention; Predictive Forward Collision Warning; Blind Spot Warning and Intervention; Lane Departure Warning and Prevention; and Forward Emergency Braking with pedestrian detection. Other notable safety features available to 2019 QX50 buyers include pre-crash seat belt technology, adaptive front lighting with high beam assist, a tire inflation indicator, and lighter steering for certain parking situations.
The all-new 2019 INFINITI QX50 features a fourth-generation version of INFINITI's Direct Adaptive Steering - the first crossover and first front-wheel drive application of the system. Direct Adaptive Steering is a steer-by-wire system that supports driver assist technologies by providing smooth operation, allowing for more direct steering responses and easy maneuverability. Direct Adaptive Steering is an enabler to steering systems that will form a key building block on the way to achieving comprehensive driver support functionality. The steer-by-wire system eliminates the need for mechanically linked parts, instead employing digital components to improve steering feel and feedback. The connection between the driver and Direct Adaptive Steering is instantaneous, thanks to the electronic connection between components.
The all-new 2019 INFINITI QX50 is built on an all-new platform, featuring a front-engine, front-wheel drive layout. Engineered with flexibility of application in mind, the FF platform sets new standards for refinement, rigidity and interior space in the compact luxury crossover segment.
The new platform is built for both front-wheel drive and all-wheel drive powertrains, making it very suitable for the QX50's intelligent AWD drivetrain. The platform's layout allows for high levels of packaging efficiency, resulting in the 2019 INFINITI QX50's ideal interior proportions for passengers and cargo. The new platform also enables the QX50 to achieve 8.6 in. ground clearance without an impact on cabin space.
Confident dynamics from all-new platform, suspension and brakes
The 2019 INFINITI QX50 offers an optimal balance of stability, comfort and ride control – quiet and refined, while also rewarding and giving confidence to the enthusiast driver.
The 2019 INFINITI QX50's new platform, with ideal rigidity, enables the car to resist flex and vibration, and allows the front and rear suspension, steering and brake components to perform at their best.
An all-new MacPherson Strut front suspension system delivers immediate responses during spirited driving, with geometry set up to also provide high levels of straight-line stability and ride sophistication. Early suspension prototype components were modelled and validated with 3-D printing, the first time INFINITI has used the technology. 3-D printing enabled the rapid creation of new parts, reducing the complexity of development.
The 2019 INFINITI QX50's new damping control system maximizes body control and ensures a comfortable ride by isolating vibrations and reducing unwanted body motions. The system, fitted to the struts, uses a floating valve in the dampers. It is tuned to provide greater control and reduce the level of elasticity in driver inputs – the lurching delay between the driver turning the wheel and the car reacting – while enabling a greater degree of compliance and shock absorption at wheel level. Under cornering, the valve adds greater damping force to reduce body roll and aid immediate handling responses. At steady straight-line speeds, a reduced level of damping force aids cruising comfort.
All-new brakes are engineered to deliver comfort and responsiveness, and provide confident braking in all conditions. The linear stroke of its brake pedal provides a reassuring level of resistance, at any point in its travel. The brake booster is tuned to prevent the car grabbing at the brakes with light pressure on the pedal, applying maximum brake force if the system detects a firmer push on the pedal.
The all-new 2019 INFINITI QX50 is fitted with ventilated disc brakes on both axles, with larger front brakes than the current QX50. The brake booster is newly designed, featuring a tie-rod system which reduces the need for higher brake pedal pressure.
The 2019 INFINITI QX50's wheels are fitted with new run-flat tires, striking a balance between design, practicality and refinement. The application of run-flats enables the fitment of low-profile tires around the 20-in. wheels, while special reinforced rubber sidewalls allow the tires to work with reduced air pressure for up to 93 miles. This gives owners the peace of mind that they can drive to a tire fitter to replace a punctured wheel, and eliminates the need to carry a spare tire, freeing up additional trunk capacity.
Global testing regime: Built to endure the toughest driving conditions in the world
The all-new INFINITI QX50 2019 has been subjected to a robust global testing regime, with 600 late-stage prototypes tested on roads and tracks all around the world in extreme weather conditions and in locations that included switchback mountain passes, arid deserts, congested urban hubs and high-speed highways.
The 2019 VC-Turbo engine was a particular focus for testing teams, following the unit's 20-year development process. INFINITI has worked on the unique multi-link technology since 1998 to validate reliability, testing more than 200 physical engine prototypes. This has included over 30,000 hours on test beds – equal to 5 million km of testing and development – and 3 million km of equivalent road testing. Testing of INFINITI's new engine has also included verification at the hands of the Renault Sport Formula One team. INFINITI drew on the motorsport team's expertise in material dynamic motion analysis to validate reliability under extreme conditions.
