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.

2019 Infiniti QX50 gets fancy-pants Autograph interior

The 2019 Infiniti QX50 has primarily garnered attention around car enthusiast circles for its variable compression engine. It's a marvel of engineering that uniquely changes its compression ratio to maximize power and fuel efficiency. It can also switch between Atkinson and regular combustion cycles, utilize multi-point or direct injection, it's turbocharged, and even features an electric motor that controls the variable compression ratio. Nifty stuff, but it seems likely that all that technobabble will make the average buyer of Infiniti's new compact SUV go crosseyed. It may not even be mentioned. "It has an engine? Great, let me see the inside." Well, dear car shopper who doesn't give a hoot about the greasy bits, have we got a bit of QX50 news for you. Infiniti has announced the QX50 Autograph package, a special $2,000 option with a seriously upgraded interior. Fancier materials and unique color schemes were selected, drawing inspiration from luxury beach resorts and being awfully similar to those found in the latest Pantone Fashion Color Trend Report. It's probably best to turn things over to the press release at this point. "Starting with warmer color tones, the rich chocolate brown replicates wood applications in the (beach) resort and the surrounding trees, followed by a creamy off-white representing the sand on a beach. The highlights of a cooler dark navy blue on the center console, reminiscent of ocean water, strike the proper balance between warm and cool, creating a comfortable, yet invigorating environment." Have you gone crosseyed? Well, now you know how it feels when describing the greasy bits to a non car person. Those cream, brown and blue bits are the Pantone colors, which, respectively, are known as "Coconut Milk," "Emperador" and "Sailor Blue." In the QX50, the Sailor Blue-esque blue is applied to the center console, dash and doors in Ultrasuede. The Emperadorish brown is on the steering wheel, leather-wrapped dash top and doors, outer portions of the seats and the lower door portions. Coconut Milk is indicative of the creamy dash color and the seat leather, which is diamond-quilted and contrast-stitched. There's also open-pore wood trim. Though I made light of this, the QX50 Autograph interior is actually quite striking. As Infiniti points out, consumers are starting to embrace color, which is worth celebrating. Give me Coconut Milk, Emperador and Sailor Blue over beige, grey and black any day.

NHTSA probing 400,000 Infiniti, Honda vehicles over steering faults

As many as 391,000 vehicles from Infiniti and Honda may eventually need to be recalled as a result of two, separately announced Preliminary Evaluations from the National Highway Traffic Safety Administration to ascertain the scope of the potential safety hazards.
The larger investigation has NHTSA looking into the 2013 Honda Accord because of 24 reports from drivers alleging total loss of power steering or a sudden increase in necessary effort to turn the vehicle. In four cases, the problem is reportedly linked to crashes, with all of them occurring at less than 30 miles per hour. According to the claims, 13 people also reported seeing a warning message during the failure. Turning off the car and restarting it would fix the issue in some cases. If a recall is necessary, it could affect an estimated 374,000 Accords.
The second investigation is much smaller in scope. The safety agency is investigating the 2008 Infiniti EX35 after two complaints of the steering wheel shaft separating, and the vehicle losing the ability to steer. Both reports allege that the steering became loose when driving and then completely failed once the vehicle was stopped. A recall for the problem would affect an estimated 17,000 vehicles. Scroll down to read NHTSA's reports on both Preliminary Evaluations.
