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.

2014 Infiniti Q50S

Ten years ago, nearly to the day, I took delivery of a brand-new 2004 Infiniti G35 6MT. The sporty rear-wheel drive sedan, equipped with its throaty 260-horsepower V6, slick manual gearbox and limited-slip differential replaced my 2001 BMW 330i because the Japanese competitor touted a product that was roomier, better equipped, quicker and lower priced. The G35 trumped the German in nearly every measurable category - at least on paper.
The 2014 Infiniti Q50 is the direct descendant, albeit two generations later, of the car I owned a decade ago. It is dimensionally about the same size, but it has gained more than 300 pounds of mass thanks to numerous safety upgrades and technical innovations. The additional weight is largely dismissed by a larger and more efficient powerplant that delivers an additional 68 horsepower, a welcome arrival, but the manual gearbox that charmed enthusiasts has been pushed out of the picture by a mandatory seven-speed automatic transmission.
As it has in the past, Infiniti touts its all-new Q50 as a luxury sport sedan worthy of the title. Decades ago, impressive performance statistics may have sealed the deal. Yet there is much more to the assignment today, as the model must offer premium appointments, sophistication and engaging driving dynamics if it's going to entice and capture the next-generation of young, premium buyers - much like the G35 did for me ten years ago.

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.
