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 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 Eau Rouge gets the heart of a GT-R [w/video]

There has been ongoing talk of an Infiniti using the Nissan GT-R powertrain practically since the moment the Nissan's flagship sports coupe hit the road. While the rumors have gone back and forth over the years, they have never completely gone away. It seems Infiniti is finally turning an ear to the screams of its most vocal enthusiasts with an updated version of the Q50 Eau Rouge concept boasting a modified version of Godzilla's engine and all-wheel drive system debuting at the 2014 Geneva Motor Show. It's even taking things a step further and granting it a new, seven-speed transmission to replace the Nissan's six-speed.
The latest evolution of the Eau Rouge packs the same 3.8-liter, twin turbocharged V6 found in the GT-R but with a unique tune of 560 horsepower and 443 pound-feet (600 Newton-meters) of torque. That makes it 15 hp more powerful than the standard 2015 GT-R but gives up 20 lb-ft of torque. Power gets to the ground through the GT-R's all-wheel-drive system. Infiniti predicts that the Eau Rouge would sprint to 60 miles per hour in less than 4 seconds and on to a top speed of 180 mph.
According to Infiniti Communications Senior Manager Kyle Bazemore in an email to Autoblog, the modded GT-R powertrain was not the only choice for the Eau Rouge. It also considered "developing a high-power sports diesel" and hybrid versions with an electric supercharger. However, "this was the clear solution for this concept car," Bazemore said. Other than the drivetrain, the Eau Rouge in Switzerland is identical to the one shown in Detroit. Sadly, it is not confirmed for production; so we might not be getting the fabled Infiniti GT-R sedan any time soon. Still, we can hope.
