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.

2017 Infiniti QX30 price anounced ahead of September launch

The 2017 Infiniti QX30 will start at $30,945 for the base model and will max out at $39,495 for the Sport trim.

Infiniti Emerg-E Concept

The Infiniti Emerg-E is a two-place hybrid gasoline-electric concept that made its world debut at the 2012 Geneva Motor Show. While its sleek shape and stunning styling dropped jaws, those on the green side of things immediately recognized it as a reskinned and updated Lotus 414E - itself a concept based on the Evora that debuted at the same show only two years earlier. Yet there is little wrong with a reworked, Infiniti-badged Lotus boasting 402 horsepower and 738 pound-feet of torque, especially when it features a lightweight, all-aluminum bonded chassis beneath an attractive carbon fiber skin penned by the automaker's Southern California design team.
The hybrid powertrain is all contained aft of the cockpit. Primary propulsion is accomplished with two electric motors, one on each rear wheel, both featuring its own single-speed transmission (this design eliminates the need for a differential and provides electronic torque vectoring control). Energy for the electric motors is stored in a 15-kWh lithium-ion battery placed behind the seats, which is chemically different from the lithium-polymer pack Lotus used in its 414E. Auxiliary propulsion comes from a Lotus-designed, all-aluminum, 1.2-liter three-cylinder gasoline engine, rated at 50 horsepower, that serves as a range-extender after the 30-mile life of the battery pack is extinguished. Teamed with an 8.1-gallon fuel tank, the combo allows the Emerg-E to cruise about 300 miles without stopping.
Offered the chance to take the Emerg-E for a quick loop around an autocross course in Southern California, I jumped at the opportunity.
