Infographics: All-new INFINITI QX50 design and engineering details

Distinctive proportions and Powerful Elegance design language set the QX50 apart. A sense of human artistry is clear with quality materials and signature INFINITI design cues: the double-arch grille, clamshell hood, crescent-cut D-pillar, ‘human-eye’ headlights and corresponding taillights . INFINITI’s double-arch grille gives the ‘face’ of the QX50 a unique and distinguished appearance . The clamshell hood flows into the character lines running along the side of the vehicle, providing the QX50 with a distinctive visual signature . 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. Rear LED taillights connect with the chrome tailgate strip, running along the side for an uninterrupted front-to-rear visual line.

The QX50’s interior design articulates a sense of advanced human artistry. The cabin’s hand-crafted feel is achieved by employing Japanese approaches to the treatment of materials. This creates a tailored appearance and ambience inside the car. 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 panels. The seats, door panels and dashboard feature a laser hole-cut stitch pattern, tailored to follow the interior’s curves. Contrast color stitching on the seats is paired with leather piping. The optional moonroof stretches across the cabin and cargo area, providing a dramatic, panoramic view of the sky for passengers. This visually enhances interior space, flooding the cabin with natural light . The sports-inspired steering wheel is shaped for a comfortable grip over long distances to minimize hand fatigue and allow the driver to feel fully in-control. Wheel-mounted paddle shifters maximize ease of use.

The QX50’s new platform presents advantages for both the driver and passengers. Efficient packaging maximizes the amount of interior space, making for unrivaled roominess and flexibility . Driver-centric, passenger-minded: technologies enhance the driving experience and create a calm, connected, and co-operative space . Interior roominess facilitated by space savings within the engine bay. The QX50’s highly compact 2.0-liter VC-Turbo engine occupies less space. INFINITI engineers combined computer simulation with real-world road testing in developing the new platform. The QX50 provides the ideal balance between ride comfort and driving performance . The new platform also enables the QX50 to achieve 218 mm (8.6 inches) ground clearance without impacting on cabin space . The trunk accommodates three golf bags, hidden under-floor storage compartments can be used to stow valuable items.

Cabin is made more flexible with its sliding rear bench. The cargo area is 990mm deep with the rear bench all the way back – increasing to 1,140 mm with the seats moved forward . Efficient packaging maximizes the amount of interior space within the QX50, with an expansive cabin and minimal intrusions by the bodywork and trim . The new platform is built for both front-wheel drive (FWD) and all-wheel drive (AWD) powertrains, making it very suitable for the QX50’s intelligent AWD drivetrain. SHF 980 MPa steel is used around the crashable zones to better absorb energy in the event of a collision, as well as weight-bearing sections around the engine bay and other key structural parts of the car. A double-ring structure provides the bodyshell with a naturally strong frame, in particular reinforcing the rear of the car and the area around the tailgate . Unprecedented rigidity allows the car to resist flex and vibrations, providing a stable base for the QX50’s front and rear suspension systems, steering and brakes to provide the driver with greater control.

Using an advanced multi-link system to raise or lower the height of the pistons’ stroke, the VC-Turbo engine offers any compression ratio between 8:1 (for power) and 14:1 (for efficiency) . INFINITI has worked on its VC-Turbo technology since 1996. The multi-link mechanism, which holds the key to the variable compression ratio, was invented in 1998 . INFINITI has tested more than 100 engine prototypes to perfect the technology, with over three million kilometers of road testing and more than 30,000 hours on the test bed . INFINITI is targeting up to a 27% improvement in fuel efficiency over similarly-powered V6 gasoline engines.

Development teams are aiming for a 200 kW (272 ps, 268 hp) maximum power output and 390 Nm torque – higher specific power output than many other four-cylinder turbo engines . The VC-Turbo engine uses a wide-range single-scroll turbocharger to provide seamless, instant access to power and torque . The VC-Turbo’s multi-link system reduces lateral movement of the connecting rods, creating just 10dB of vibration noise – 20 dB less than a conventional four-cylinder engine. The engine development involved the Renault Sport Formula 1 Team, calling on their deep material knowledge and expertise dealing with high RPM. The VC-Turbo engine is so smooth, it requires no balance shafts – conventional four-cylinder engines require two. Removing them offsets the space occupied by the multi-link system.
