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.

Infiniti to launch first electric car, to be made in China

BEIJING — The first electric car for Nissan's premium brand Infiniti will be a sporty sedan produced in China, the Japanese carmaker said in a statement viewed by Reuters ahead of a public announcement expected as soon as Wednesday. The vehicle would hit the market in around three years, and consumers would get a taste when the company unveils a concept car, dubbed the Qs Inspiration electric sedan, at the Shanghai auto show later this week, Nissan officials said. "China has the most growth potential for electric vehicles globally, especially in the premium segment," Infiniti Chairman Christian Meunier said in the statement seen by Reuters. Automakers operating in China have to sell more so-called new-energy vehicles, either battery electric cars or plug-in electric hybrids, to comply with official production quotas designed to reduce smog. It was not immediately clear whether Infiniti planned to produce its first electric vehicle in other markets. An Infiniti spokesman said, however, the brand did not intend to export the e-sedan from China. The planned e-sedan is part of Infiniti's longer-term strategy to significantly electrify its product lineup. Brand officials have said that from 2021 every Infiniti model launched will be either an all-electric car or so-called "e-Power" hybrids, underlining Nissan's previously announced plan to make Infiniti primarily an electrified offering. The sedan likely would be built on a new flexible architecture developed specifically to accommodate electrified powertrains, Infiniti said in the statement. Its design, especially the interior, would be significantly different than current models, design chief Karim Habib said. EVs do not have bulky gasoline engines and transmissions, opening up space inside the car. "It will have a flat floor, and if you are a passenger you can cross your legs or stretch out your legs," Habib told Reuters. Competition in China's rapidly emerging electric car market is heating up amid an onslaught of models from startups such as Nio and WM Motor, as well as those from established automakers. In the luxury segment, Infiniti will be competing with Tesla Model S and Model X, as well as other models due to be launched in coming months by Audi, Mercedes-Benz, BMW and Lexus.

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.
