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 bringing Q50 Eau Rouge to Geneva, now with engine [w/video]

During last month's Detroit Auto Show, Infiniti rolled out the lustrous Q50 Moulin Eau Rouge concept - a preview of what could be a solid performance offering from Nissan's luxury arm. Problem is, the car shown in Detroit was all show and no go - literally.
Infiniti was keen to talk about how the Eau Rouge would feature "a big personality, V-cylinder engine with forced induction" with "over 500 horsepower and 600 pound-feet of torque," but the showcar had no such powerplant underhood. In fact, it didn't have any powerplant under the hood at all. That'll change next month, however, as Infiniti has now confirmed that it will bring the Q50 Eau Rouge to the Geneva Motor Show in March, complete with the promised "big personality" engine.
"Our engineers have perfectly captured the tone of Infiniti's take on premium performance, and a car that is as impressive as the Q50 Eau Rouge sounds is surely a car to challenge performance cars in the premium sector," said Infiniti's President, Johan de Nysschen. Regarding that sound: he ain't foolin' - the automaker has released a teaser video that gives us our first listen at what the Q50 Eau Rouge will sound like once its powerplant is nestled underhood. Scroll down to give it a watch - err, listen - and have a look beyond that for the company's official press blast.

Infiniti Q60 Concept previews sexy styling, twin-turbo V6

Okay Infiniti, this was worth the waiting and teasing. Behold, the Q60 Concept, the coupe that foreshadows a future production two-door while also introducing a new family of 3.0-liter, twin-turbocharged V6 engines. It's fair to say we like it very much. Of course, this is not our first unfettered look at the Q60 Concept. Infiniti's final "teaser" image showed off the final product, but now we can analyze it from all angles, including the lovely, almost S-Class Coupe-like rear end and the clean, fashionable cabin. The Q60 Concept's design, particularly in the swoopy profile, comes across as organic and muscular, particularly in the shape of the front fenders and rear haunches. The car's dead front view reveals a few styling details that were overshadowed by the angle of the teaser image, like the interesting ridge that runs from the grille into the powerfully domed hood. A fixed glass roof gives the cabin an open-air feel, while the overall layout is largely reminiscent of the current Q50 sedan, only with cleaner, updated materials that we wouldn't bet on making production. Thin sport seats look supporting and feature quilted leather bolsters, while a two-tone steering wheel spices up the driving environment. Under the Q60 Concept's hood is the same 3.0-liter, twin-turbocharged V6 that was first shown on the Q80 Inspiration Concept from the 2014 Paris Motor Show. According to Infiniti, the direct-injected six-pot will arrive in a production car within the next two years. In the Q60, a seven-speed automatic handles power delivery, although it's unclear if a similar gearbox would be used alongside the production engine. Other notable features on this sleek two-door include Infiniti's Direct Adaptive Steering system and the new InTuition system, which promises a "fully customizable digital environment." Of course, we'll have much, much more on the Q60 Concept tomorrow, when it makes it arrives on the floor of the 2015 North American International Auto Show in Detroit.
