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 Q50 Eau Rouge racing toward Detroit with Red Bull in its veins

There are several ways an automaker can get into Formula One racing. It can start its own team from scratch (like Toyota did in 2002), it can buy an existing team (like BMW did with Sauber in 2005) or it can supply engines to other teams (as so many manufacturers have done over the years). Infiniti chose another direction and opted to sponsor the world-champion Red Bull Racing team.
Infiniti has undoubtedly poured millions into its partnership with Red Bull since it started in 2011, but aside from the Sebastian Vettel edition FX (which technically emerged from the company's sponsorship of the driver as separate from the team), the tie-in has yet to translate into a Red Bull-tuned (or at least -inspired) Infiniti for the road. But that's just what Nissan's premium brand has in store for us at the upcoming Detroit Auto Show in January.
Well, almost, because the concept just announced is still a step or two away from reaching your local Infiniti dealership, but here it is just the same. It's called the Q50 Eau Rouge, and it's based on the company's latest tech-laden sports sedan. It takes its name, of course, from the famous uphill section of the Spa-Francorchamps circuit where Sebastian Vettel won the Belgian Grand Prix earlier this year, but Infiniti isn't telling us much more than that.

Infiniti boss De Nysschen confirms next-gen Q60 Coupe, ponders high-performance variants

We've known since mid-December that Infiniti's new global model naming convention would turn the current-generation G37 Coupe into the Q60 Coupe starting next year, but we haven't been clear on whether the model-range-formerly-known-as-G would get a successor, especially as its volume has traditionally been a lot lower than its sedan counterpart.
Thankfully, Infiniti president Johann De Nysschen (above) has stepped up to confirm that the newly revealed Q50 sedan will receive a two-door counterpart, though perhaps not as quickly as some would like. According to an interview with Australia's CarAdvice.com, De Nysschen says "the coupe we can probably expect two-and-a-half to three years down the road." That news also suggests that if there's an eventual convertible version, that it's a long way off, too. Why so long? Infiniti has "a lot of priorities" - priorities that undoubtedly include an already-confirmed front-wheel-drive small hatchback/crossover.
The report also indicates that Infiniti has some aspirations for stretching its new Q50/Q60 range in a higher-performance direction to take on competitors like BMW and Audi, the latter being De Nysschen's former employer. There's far from a firm timetable offered, of course, with De Nysschen saying "someday in the future we will be able to offer more high performance versions [of Q50] than we have today... the dynamic capabilities of this platform are very significant. It can handle far higher power than the engines we are using at launch."
