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.

Sebastien Vettel testing Infiniti's production Etherea?

It sounds like Sebastian Vettel has had his hands full recently, juggling his Formula One racing career while moonlighting as the newly appointed director of performance at Infiniti. On that latter note, Autocar is reporting that Vettel has been testing a production version of the Etherea Concept at France's Circuit Paul Ricard.
There is still no word as to when we could see this car go into production or what it will be called (possibly the Q30), but it will likely share a platform with the Mercedes-Benz A-Class as a part of the Daimler/Renault-Nissan collaboration. The article also said that this future entry-level Infiniti would be produced at Nissan's Sunderland, UK plant.

Infiniti confirms all-new sports sedan will debut in Detroit

While the automotive world may currently be focused on the Los Angeles Auto Show, those looking to stay ahead of the curve have their sights set farther down the road. One such automaker is Infiniti. On the first of the LA press days, the Japanese luxury brand has announced an all-new model to debut in Detroit this January.
According to Infiniti, an all-new model will be unveiled at the 2013 North American International Auto show. The debut will be accompanied by a performance from world renowned Cirque Du Soleil as well as a live stream simulcast of the event.
It's unclear whether Infiniti will be showing a redesign of the G sedan, which has been spotted testing, or a new sub-G compact performance-luxury four-door. We will know for sure on January 14 when we bring you news form the Infiniti stand.
