Infiniti Q50S getting G37's hydraulic steering for 2016

Sometimes, new technology doesn't make things better. Take the march of power steering technology as an example. Electrically assisted systems are in vogue at the moment for their ability to increase fuel efficiency, but tuning them to offer good feedback remains something of a dark art. Some automakers get it, but most don't. The previous hydraulically assisted setups just seem to be inherently more communicative when driven with enthusiasm. And it looks like Infiniti might be learning this lesson the hard way.
In talking with Keith St. Clair, the luxury brand's head of product planning, Car and Driver has learned that the Q50S is probably going to ditch its standard electrically assisted steering in favor of a hydraulic system derived from the old G37, a model soon to be renamed the Q40. The system should make the sedan more engaging behind the wheel, but it still won't help those who tick the option box for Infiniti's controversial Direct Adaptive Steering drive-by-wire system.
According to St. Clair, Infiniti's engineers have heard the complaints of critics and previous G37 owners about the Q50S model's electric steering system, and wanted to see what they could do. They didn't have to go far to figure it out - all it required was taking the steering rack off of a G37 and putting it onto the Q50S. After a little tweaking, "the car is a blast to drive," St. Clair reports. Now, the company is said to be fast-tracking the switch, and it could be ready for the 2016 model year.

Infiniti JX35 QX60 Hybrid confirmed for New York debut

The next Q-ified Infiniti will be making its debut at the New York Auto Show later this month, the QX60 - the crossover formerly known as JX35. And while there aren't many changes to the crossover in terms of design or function, the big news is that Infiniti will be revealing a production hybrid powertrain option for its seven-passenger luxury/utility vehicle.
The QX60 Hybrid uses the same powetrain found in Infiniti's M35h gasoline-electric sedan, which couples a 2.5-liter supercharged four-cylinder engine with a 15-kilowatt electric motor, running to the wheels via continuously variable transmission. Both front- and all-wheel-drive versions of the QX60 Hybrid will be available, and Infiniti says that the more efficient CUV should be good for around 26 miles per gallon combined - an improvement of five mpg over the current JX35 with its 3.5-liter naturally aspirated V6. And because the compact lithium-ion battery will be housed underneath the third row seat, we're told that the hybrid model will still have the same passenger and cargo capacity of the non-hybrid crossover.
This will be the first three-row hybrid CUV offered in the US market, and wrapping it up in a luxury package makes a lot of sense to us, since it could be a good way of cajoling customers into absorbing the extra cost of the more expensive powertrain. (Keyword in that sentence: CUV. After all, the Cadillac Escalade is still currently available as a two-mode hybrid for the 2013 model year.) Infiniti has not released official pricing figures, but says that the hybrid model will represent a roughly $3,000 premium over the standard QX60.

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.
