Infiniti QX55 Luggage Test | The price to be paid for a coupe

The Infiniti QX55 is the crossover-coupe version of the QX50, which like other such variants available throughout the industry, chops the roofline and cargo area down to create a "coupe-like" appearance. Obviously, this results in a reduction in cargo capacity, but because that reduction is largely above the back seat line, the actual reduction in usable cargo space isn't as great as you might expect. While carrying a large box or some other tall, bulky thing will be more difficult, smaller items like suitcases won't necessarily be much different since carrying them above the back seat line can reduce or eliminate rear visibility and create a hazard by flying forward while stopping as well. It's for those very reasons I don't stack to the roof in luggage tests. Now, I have not tested the QX50, so I have no point of comparison in that regard. But I have tested a variety of crossover-coupes and the QX55 does indeed share common attributes ... and detriments.  On paper, the Infiniti QX55 has 26.9 cubic-feet of cargo space behind its back seat. That is basically the same as the Audi e-Tron Sportback and a bit less than the Mustang Mach-E and Toyota Venza. The Cayenne Coupe figure just seems inaccurate.  The QX55's back seat reclines, however, so its amount is variable. I do not know where Infiniti set it while doing it's measurement, but I set it for a comfortable degree comparable to most fixed back seats. You can also easily lower the back seat with handles in the cargo area. Both elements are pictured below.  Now, let's get to the bags. As in every luggage test I do, I use two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D). Cool, that was easy. All the bags easily fit with minimal Tetrising and ... Oh no. Wait, they don't. Despite all the bags seeming to be clear of the liftgate, the power-closing function got stuck repeatedly. I could slam it shut manually, but that's another no-no here at Luggage Test Portland in order to keep things consistent.  I then Tetrised and Tetrised and Tetrised again. No good, no good, no good. "Boy, what an annoying cargo area," I said to an empty street. This is what eventually worked after the sixth attempt.

2025 Infiniti QX80 confirmed with 450-hp twin-turbo V6, 50 hp more than now

Infiniti's back to tease the 2025 QX80 that debuts in 15 days. Automaker executive Ivan Espinoza starts by telling us what we already knew, the ancient 5.6-liter V8 gets sent packing by a 3.5-liter V6. Espinoza calls it "all-new," but this is in reference to the application. Parent company Nissan loves itself a TTV6, the GT-R given the codename VR38DETT, the new Nissan Z's version codenamed VR30DDTT, the same mill formerly serving the Infiniti Q50 and Q60. The 3.5-liter displacement in the QX80 means its engine can be expected to be called the VR35DDTT. We've got output numbers at last, those being 450 horsepower and 515 pound-feet of torque, improvements of 50 hp and guaranteed-to-feel-it 102 lb-ft. That outdoes the closest Japanese competition, the Lexus LX that gets 409 hp and 479 lb-ft from its TTV6. The 2025 QX80 is going to shift through a nine-speed automatic gearbox, the two additional cogs over today's seven-speed providing a 40% wider range of ratios. Owners are going to get more performance down low and efficiency up high. Doubling up on the efficiency, engineers added active grille shutters to reduce drag when massive cooling isn't needed. Espinoza also cites "a new chassis and larger frame," however, the QX80 is expected to ride on an updated version of the current SUV's body-on-frame platform, Nissan's F-Alpha that once served the Pathfinder and Titan, plus the erstwhile QX56, and still serves the Nissan Frontier. The evolution yields 57% more lateral stiffness and 25% more torsional rigidity. A new electronic air suspension with active damping keeps the hardened cage from becoming a punishment. We get our best, albeit very brief, looks at the interior as well. The four-spoke wheel is now a two-spoke wheel, a la Genesis. The digital gauge cluster and separate infotainment binnacle morphed into what looks like a single, uncovered widescreen (composed of two or more screens), akin to what we've seen in several electric vehicles like the Kia EV9 and Honda e. The restraint and subtlety in these snippets matches what's been done to the exterior, so far as we can see. The livestreamed reveal happens March 20, expect a Monograph Concept plus some flourishes. A week later, we'll get up close and personal for the 2025 QX80's public debut at the New York Auto Show.

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.
