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 G37 to live on in showrooms alongside 2014 Q50

Infiniti is preparing to roll out its hotly anticipated 2014 Q50, a car that not only ushers in a new alphanumeric naming strategy, it ostensibly replaces the G37 as the brand's bread-and-butter sport sedan. That will happen, but not in the short-term, as the G37 will continue to be manufactured and sold alongside the Q50, at least for the rest of this year.
Infiniti spokesman Kyle Bazemore has confirmed to Autoblog that a decision is pending on how long to extend the G37 sedan's production run. "We're taking Q50 up a little bit, and that allows us to keep the G Sedan in the lineup... It [Q50] certainly started as a replacement, but it ended up being much more than that." Confusingly, Infiniti has already announced that the Q50 is to start at $37,605 (including $905 destination charge), yet the 2013 G37 is more expensive, starting at $38,255 delivered according to Infiniti's consumer website. Thus, a price drop on the G37 is likely coming in short order.
So why hold on to the older model? With the Q50 launching exclusively with V6 and Hybrid models (a turbo four and diesel are said to be in the cards down the road), Infiniti evidently feels it is risking leaving lower-end sales on the table. "There's a lot of movement with the [BMW] 320i and such, and this allows us a two-tier strategy to compete," says Bazemore. Keeping the G37 on tap at a lower price for fleet sale duty may also serve to protect the Q50 as it establishes itself on the market.

Assessing Sebastian Vettel's first 100 days as Infiniti's director of performance

Whenever a new US president is elected, we know to expect a performance review as soon as he (or she) has spent 100 days in office. Sebastian Vettel, arguably given a job that is more important to Infiniti than the US president, has been the brand's director of performance for one hundred revolutions of The Blue Marble, and Infiniti has put together a videographic glimpse of his work at Paul Ricard, in the US and England.
We probably won't really get a grip on the full results of his efforts for a while - we doubt that he's been in his post long enough to significantly alter the trajectory of the Q50 sedan, for instance. But then again, Infiniti insists he's been integral to the car's dynamics development regime, suggesting he's been working as a test driver for some time before these 100 days. Of course, Vettel is a race car driver and brand ambassador first and foremost, but when he tells a Q50 engineer that "For the future, I think it's more comfortable to have the shift paddles on the steering wheel," we get the sense that he won't hesitate to suggest changes in forthcoming products. Check out more of his inputs in the video below as well as a press release detailing his visit to the tech center in Cranfield, UK.
