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 showcases Vision Gran Turismo concept in the metal

Automakers have been clamoring to convey their ethos to a new generation and cast their brand in a positive light through the Vision Gran Turismo series. But while these concepts are designed for the virtual reality of Gran Turismo 6, some automakers have gone a step further by pulling their creations out of cyberspace and rendering them in the metal. And that's just what Infiniti has done with its design. Infiniti revealed its Concept Vision Gran Turismo back in December, striking a a sleek, low-slung form that looks more polished than a racing car but more track-focused than most concepts. It's powered (at least hypothetically) by a 4.5-liter V8 hybrid powertrain, with center-lock carbon-fiber wheels and rearward-biased 45/55 weight distribution. It's the kind of beast we'd love to drive, but while that may only be possible on Playstation, at least we know it does exist in physical reality – even if only as a full-scale model. Infiniti showcased it alongside the Q80 Inspiration and Q60 Concept at an exclusive event during the Shanghai Motor Show last week, but just revealed the photos now, so you can scope them out in the slideshow above.

The evening occasion took place at the Shanghai Himalayas Art Museum. Under the theme of "Aesthetics of Contrast," Infiniti Design Night showcased three design concepts showing an exciting path to Infiniti's future: the Q80 Inspiration (first shown in Paris, October 2014), Q60 Concept (Detroit, January 2015), and the Vision Gran Turismo designed especially for the latest Gran Turismo® 6™ video game. This was the first time the Vision GT was displayed as a real "flesh and bones" concept car, having only been seen and experienced digitally in GT6 prior to this event. The dramatic Infiniti Concept Vision Gran Turismo The Infiniti Concept Vision Gran Turismo is a vision of what a high performance Infiniti could look like in the future. Available for download in GT6 exclusively on the PlayStation®3 system, it was created through close collaboration with the creators of Gran Turismo®, the racing game franchise developed by Polyphony Digital Inc. that has sold more than 72 million copies worldwide.

MotorWeek revisits 1990 Infiniti Q45

With the one-two punch of the Lexus LS 400 and Infiniti Q45 in the early '90s, Japanese automakers started taking the fight directly to the established V8-powered German flagships on American roads. Here, we get MotorWeek's take on the latter and probably lesser known of those luxury sedans. While not so impressive today, the Q45's 4.5-liter V8 with 278 horsepower and 292 pound-feet of torque was pretty good by the contemporary standards. The big sedan was also offered with an optional all-wheel steering system that made the model quite a capable handler. The rear end even stepped out a just little during MotorWeek's slalom. Unfortunately, styling is very polarizing with these early sedans. Where the early LS looks planted with its big, chunky lines on the outside, the Infiniti is a bit more delicate. The design just doesn't scream about being a flagship sedan. The interior doesn't help sell the car as the top of luxury, either. While MotorWeek likes some of the amenities inside, there are complains about the reused switches from the Nissan Maxima and the extensive use of plastic, rather than wood. With Infiniti now having its sights on the global premium market and soon entering the compact segment, it's fascinating to see the very roots of the brand.
