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 announces pricing for 2014 QX60 and QX70

With the exception of the G37, customers walking into Infiniti showrooms this summer are going to see a bunch of different names pop up as the automaker switches to its new Q-for-car and QX-for-crossover/SUV naming convention for 2014. The first of these renamed models are the 2014 QX60 (which replaces the JX) starting at $41,550* and the 2014 QX70 (which replaces the FX) priced at $44,950* (*prices do not include $995 for destination), and both are on sale now.
Compared to the outgoing models, the new QX60 (seen above, click to enlarge) lineup starts $300 more than the outgoing JX models (base and AWD), while pricing for the QX70 will remain the same as the trio of 2013 FX models (FX37, FX37 AWD and FX50). What is still unclear is how much the all-new QX60 Hybrid model will cost or how much option and package pricing will change, if any. Scroll down for more info on the new QX60 and QX70 crossovers.

Infiniti extends long-wheelbase Q50 L for the Chinese market

Want to sell your luxury sedan in China? You're going to need a long-wheelbase model. Not because the still-dominant Chinese government mandates it, or because the customers are taller, but because Chinese buyers tend to like being chauffeured around in the back of their luxury sedans instead of driving themselves, so the priority is on rear-seat space over driving dynamics.
We've seen the likes of Audi, BMW, Cadillac, Mercedes-Benz and Volvo all roll out long-wheelbase versions of their compact and midsize sedans specifically to cater to Chinese tastes. Even Infiniti - which now bases itself in Hong Kong - offers a long-wheelbase Q70 L not only in China but around the world, and has now bolstered its extended offerings with the reveal of the Q50 L, set to debut at the Chengdu Motor Show later this month.
Set to be produced locally for the local market, the Q50 L adds nearly two inches to the wheelbase of the Q50 to the benefit of rear-seat legroom. Power comes from Infiniti's 2.0-liter turbo four offering 208 horsepower and 236 pound-feet of torque, driving to the rear wheels through a seven-speed automatic transmission with drive-by-wire steering.
