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.

2022 Infiniti QX80 Interior Review | Refreshed, but still behind

You might assume the 2022 Infiniti QX80’s interior is filled with outdated technology from when it launched here about 10 years ago, but thatÂ’s not entirely true. You see, despite the rest of the car carrying over from the previous model year, the 2022 model year QX80 enjoys a refreshed interior. While this interior is updated, thereÂ’s no need to get overly excited. Nissan put the Armada through a mid-cycle refresh last year, and the QX80 essentially cribs all of its new bits directly from the Nissan. WeÂ’ve already tested the Armada, so we had an idea about what to expect when the refreshed QX80 landed at our doorstep. Thankfully, for InfinitiÂ’s sake, the ArmadaÂ’s new interior is nice enough that it's largely acceptable in the more luxurious QX80. It features a new, high-res touchscreen, flashy plastics, a simple layout and vital tech like a wireless phone charger, USB-C port and wireless Apple CarPlay — unfortunately, Android Auto remains a wired-only affair. The new look of this tall and vast center stack doesnÂ’t jive perfectly with the QX80Â’s flowy, rounded interior design, but thatÂ’s what you get when part of the interior is updated and the rest is left to carryover. Straight, strong lines dominate the center stack, complemented by rectangular vents. Meanwhile, rounded wood trim flows out of this brutalist center stack in a jarring manner that makes the interior look like two different designers worked on it separately, then had their work combined.  Functionally, the new parts of the interior are just fine. The new single touchscreen and its supporting user interface is a welcome update over the old dual-screen infotainment system that's still found in other Infinitis (it had only just received that system for 2020). Its large, width-oriented and mounted higher for easy viewing, plus the presence of supporting physical knobs and buttons make vital controls easy to use and adjust. The odd storage compartment in the dash houses the wireless phone charger, and the 12V outlet is hidden in there alongside it. We enjoyed the presence of a wireless phone charger, but it didnÂ’t charge our phones quickly, and the phoneÂ’s movement on the mat would sometimes cause it to stop charging altogether. Surprisingly, the QX80 is fitted with a camera rearview mirror, which was a nice surprise to see.

Infiniti Q80 Inspiration imagines future of brand's luxury flagship

Infiniti is among the best of the non-exotic brands when it comes to crafting concepts, with designers who just seem to know how to show a truly wild vehicle with subtle hints at a future model. Just take a look at its latest Q80 Inspiration at the 2014 Paris Motor Show to see what we mean.
Infiniti claims that the Q80 imagines how it would build a future, fullsize luxury sedan to take on the stalwart Mercedes-Benz S-Class. However, in the current form it seems like a flight of fancy. It's packed with fabulously weird styling tricks, including birdwing-shaped headlights. There's also the roof and windshield that look at first glance to be a single piece of teardrop-shaped glass terminating at a boat-tail rear. In addition, the Inspiration has every concept designer's favorite gimmick - suicide doors.
Under the hood sits a twin-turbocharged 3.0-liter V6 and electric motor hybrid with a claimed 550 horsepower. The company asserts that the powertrain is actually on the way in the next two years and could do 43 miles per gallon (5.5 liters per 100 kilometers), though it's not specified on what driving cycle that's calculated on.
