As to its positive features, like line steer, you can find those in other cars without steer-by-wire.
With 10 years of engineering effort, I doubt that there was any real cost cutting involved, and with the decision made to retain the mechanical backup in case of power failure, the effort may have turned out to be "do it for the sake of doing it" rather than for any cost cutting or safety reasons.

The features that the Nissan steer-by-wire system provides has already been done with electrically power-assisted steering systems that use an electric motor instead of hydraulics to assist steering. We already have autonomous steering (auto-parking systems) on cars without having to give up the mechanical steering shaft; electric motors have enough torque to overcome the effort a human driver exerts on the steering wheel.

if that's true, then there's really no benefit.

This is the next step in drive-by-wire technology but I myself would not want to drive a car that does not have some sort of mechanical backup:
have you tried steering and braking with the ignition off lately?

they could have said 100 years in the making, it is just a PR. When you remove half of the hardware and end up with inferior product, only good reason for it could be cost cutting.

That a lot of time to spend on a feature that most editors will tear apart in less than a 15 min drive. Solution is just buy the Q50 with the normal steering

The only problem with that is you can't get certain features without getting DAS as part of it. That's how they get you.. bast***ds

I'm driving it now without DAS..its not much better…. the Q50 is a great value with the new lease deals being offered but they really turned it into a RWD ES, the G37 had much better steering….

Surely they will improve DAS and consumers will move to it over time. I just think if you want a sporty vehicle that isn't the feature to get, its too disconnected as every single review has stated. For cruiser cars, its likely okay as people don't mind a detached feeling. Imagine this in a Camry or Accord, its fine. In a car positioned as a sport sedan, it wasn't a great idea. Adding run-flat tires doesn't help DAS either or a sport feeling. Feels like its on ice.

Maybe they should have debuted it on something like the JX/Q60 where it is a floaty, disconnected SUV so expectations for sport would be very low and the DAS would be better received.

Default 2014 Infiniti Q50's novel drive-by-wire steering system recalled


Quote:
The gradual replacement of mechanical components in automobiles with electronic systems brings with it definite advantages, but also poses certain potential dangers. Just think of the inevitable problems you've encountered with the computer on which you're reading these words and you'll know what we mean. But a computer crashing isn't as problematic as your car going on the fritz when its electronic systems fail.

That's what Infiniti is being reminded of with its new drive-by-wire electronic steering system. The Japanese automaker developed and installed the Direct Adaptive Steering System in its new Q50 sedan, but a small number of those cars on the road are now being recalled due to that system.

According to the National Highway Traffic Safety Administration, on a small number of examples, the Q50's optional by-wire system may fail if the temperature in the engine compartment drops below freezing. There's a backup mechanical setup in place should the electronic system fail, but NHTSA says that the backup system may also fail to engage in time to avoid a crash.

Since the problem only seems to affect a specific version of the software that governs the steering system, just 23 vehicles are being recalled for this issue, which is a very small recall in the face of other campaigns that often affect thousands, tens of thousands, hundreds of thousands or even millions of vehicles. But the particular nature of this problem makes it rather unique. See the full announcement below for details.

Needs more refinement. Maybe knock on Lexus's door and ask for a tip or two about refinement

They really should have debuted this in one of their 4 SUVs first and not their sport sedan…makes plenty of sense in a JX…..

Its a first, it will have bugs, even after 10 years of development..You should read the Q50 forums..some crazy stories...

Infiniti Reveals First Image of Q50 Eau Rouge Concept
http://www.automobilemag.com/auto_sh...cept-detailed/
Quote:
-Q50 Eau Rouge represents design vision for high-performance products
-Design of Q50 Eau Rouge features dramatic aerodynamic styling influenced by Infiniti's involvement in Formula One
-Q50 Eau Rouge features complex carbon composite bodywork

Infiniti has revealed the first image of the Q50 Eau Rouge concept which will have its world premiere at the 2014 North American International Auto Show in Detroit on January 13.

The Q50 Eau Rouge, a high-performance design concept based on Infiniti's Q50 premium sports sedan, draws inspiration for aerodynamic design from the technical collaboration between Infiniti and four-time Formula One World Champions Infiniti Red Bull Racing.

Major bodywork components have been redesigned with aerodynamics in mind and manufactured carbon fiber. Q50 Eau Rouge is lower and wider - only the roof and door profiles remain unchanged from the production Q50. This striking design is inspired by muscularity, refinement, and understated performance intent.

Infiniti Q50 Eau Rouge highlights include deep and detailed carbon fiber front splitter, rear diffuser and side sill skirts; carbon fiber roof and door mirror casings; 21-inch lightweight forged alloy wheels; and a dual-exit exhaust sports system below a large integrated rear spoiler.

The Infiniti design team, led by Executive Design Director Alfonso Albaisa, was influenced by the aerodynamic styling approach taken by their colleagues at Infiniti Red Bull Racing.

"From our shared passion for performance with Infiniti Red Bull Racing grew a collective desire to produce a vision of what a high-performance Infiniti Q50 could look like," said Albaisa.

"The design has a number of distinctive Formula One inspired touches. In particular, the sculpted front wing assembly and the rear aerodynamic packaging take their cues from the RB9 race car," added Albaisa.

Infiniti is also empowering social fans to unveil the all-new Q50 Eau Rouge concept car ahead of the official launch at the Detroit Motor Show on January 13. Starting from today, online advocates can drive the reveal of Infiniti's latest concept car. By sharing their views and comments through social media channels like Twitter (hashtag #F1Q50), Facebook and Weibo, fans will build the image of the concept in a virtual garage. Each "share" will help build individual Q50 components, and as more fans share, the quicker the car will be "built." Progress can be viewed on unveil.infiniti.com.

More information about the Q50 Eau Rouge will be revealed during a press conference at the North American International Auto Show at 9:20 a.m. ET on January 14.


NISMO Q50 or Q50 NISMO, sound so much better.
