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.

2015 Infiniti Q70 stretches out in NYC

Infiniti released its refreshed Q70 (the car formerly known as "M") in New York this morning. The luxury sedan is brings with it, quite literally, a big change: it's now the only vehicle in its segment to offer both long- and short-wheelbase options here in the US (other automakers do this in China). Currently, the two-wheelbase sedan strategy is exclusive to the ranks of fullsize players like the BMW 7 Series, Audi A8, etc.
Infiniti has elongated the standard Q70's wheelbase from 114.2 inches to 120.1 inches, in doing so lengthening the car 7.3 inches overall. For the sake of comparison, a standard wheelbase Audi A8 runs 117.8 inches, so the Q70 is no slouch. The extension mostly benefits rear-seat occupants, who are treated to an extra 5.6 inches of legroom. We think the enlargement improves the car's aesthetic, as well.
In addition to the long-wheelbase option, there are a few other tweaks in store for 2015. New head and taillights are the biggest changes, with full LEDs in the back and LED accents in front. Aspects currently seen on the smaller Q50 are evident, as well, such as the "double-arch" grille that comes with mesh-finish inserts. The fascia also includes a new front bumper with integrated foglights. Interior changes seem to be fairly minimal, but that's not necessarily a bad thing. The outgoing Q70 had a spacious (if dated), luxurious cabin with all kinds of high-quality materials.

2014 Infiniti Q50, Lexus IS 250 fail to achieve Consumer Reports 'Recommended' rating

Infiniti and Lexus might be a little concerned now that both of their new luxury sedans, the Q50 and IS250, were unable to net Consumer Reports vaunted "Recommended" rating during their first year on the market. In fact, not only did the two fail to earn a "Recommended" rating, they finished behind the vast majority of the competition after testing, including the BMW 328i, Mercedes-Benz C250, Lincoln MKZ and Volvo S60 T5.
The Q50 managed to snag a "Very Good" rating overall, but CR criticized it's road manners for not being as thrilling as the car it (sort of) replaces, the G37. The mag called the handling mundane and the steering dull, while also remarking on the poor controls. According to CR, the interior quality is "nothing special." Shade was also thrown at the Q50's reportedly poor ride.
Compared to the IS, though, the Q50 got off easy. CR called it "neither sporty nor luxurious," while criticizing the 2.5-liter V6's lack of oomph and poor fuel economy. The mag then went on to lambaste the IS's handling, steering, interior, cabin space and infotainment system.
