Infiniti QX70 is fini, for now

We knew it first as the FX, debuting in 2003 as a bulgingly macho SUV/crossover thing with an impossibly long hood. It was quick and powerful, and lower-slung than typical SUVs, more like a tall wagon. Infiniti later dialed the cartoonishness of it back a few notches and started calling it the QX70. Now, the QX70 is going to take a little break, disappearing from the lineup for a few years while QX50 and QX80 redesigns are rolled out. The QX70 is sporty, with a 325-horsepower 3.7-liter V6. But it's an aging model and a bit of a slow seller - last year, Infiniti moved one-seventh as many QX70s as it did its kid-hauling cousin the QX60 - which seats more people (seven, to the QX70's five) and is less expensive. The QX70 was once popular like that, selling 30,964 as the FX in 2004. But that was long, long ago. Last year it sold 6,261. The QX70 nameplate is expected to be back in 2021 or 2022, in a redesign based on the Nissan Murano and built at Nissan's plant in Canton, Miss.

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.

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.
