Infiniti QX Inspiration Concept SUV may be the most Japanese thing in Detroit

Infiniti is following up its Q Inspiration Concept from the Detroit Auto Show last year with a QX Inspiration Concept for 2019. Unlike the Q Inspiration from last year ( VC-Turbo engine), this one is fully electric. That said, it does sport a similar design language. This QX concept is meant to preview an upcoming midsize electric Infiniti SUV. Since it's powered by an electric powertrain, there's no need for a grille. Infiniti decided to take the opportunity to spell its name out in big and bold letters across the bow instead. The proportions are obviously concept-car-like with a high beltline and squashed rear-end. Straight lines and muscular curves accentuate the car's stance nearly everywhere you look — somehow we still didn't escape the plastic wheel arches breaking up the pretty white paint and surrounding the 22-inch wheels.

Infiniti emphasizes that it used Japanese "Ma" styling, which puts an emphasis on negative space. Take a look through the photos yourself to see if you think Infiniti succeeded at utilizing the design mantra of "white space" on this SUV. One neat feature you'll easily be able to decipher on the exterior is the use of Japanese red cedar slats on the roof. You can see straight out of the car from inside, and it offers a bit of contrast color-wise. A lot of the magic is contained in the interior of the QX Inspiration, though. The first thing you'll see is the pillar-to-pillar screen that's finished in gold-tinted glass. Remind anyone of Byton? As if that wasn't enough screen, Infiniti also put a screen in the square steering wheel, too. The center console is made using marble, extending all the way back to the rear seats. White, suede rhombus panels serve as the Infiniti's floor that also features gold inlays. Infiniti takes advantage of the electric car benefit of a flat floor for extra interior space — the battery sits low under it.

Infiniti says it intentionally left out any technology from the backseat so as to give the cabin a more natural and authentic appearance in pursuing the Japanese appreciation of nature and craftsmanship.

Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Infiniti Q50 steer-by-wire system took 10 years to develop [w/video]

Infiniti's Direct Adaptive Steering (DAS) is quite a novelty - the system employs no physical connection between the steering wheel and the front wheels under normal circumstances and instead relies on a computer, clutch and steering-angle actuator to guide vehicles down the road with input from the driver.
In our First Drive review of a 2014 Infiniti Q50 equipped with the system, we weren't overly impressed by the artificial feedback. But we can't help but be impressed with how long Infiniti spent on its development: a full 10 years, according to Autoline Daily in the video report below. A staggering 70 percent of the research and development time spent on DAS was devoted to getting the steering feel right, and unfortunately, our first impression suggests their results still leave something to be desired, as we found it lacked the sporty feeling a sport sedan should have.
The weight of DAS is comparable to that of a conventional steering system due to its complexity. For example, three ECUs are used in the first-generation DAS system to ensure there's never a loss of steering, but Infiniti is refining the technology and is working to simplify it to reduce weight. One day Infiniti hopes that only one ECU will be needed to control DAS. We just hope it doesn't take the Japanese automaker another ten years to get the steering feel right.
