2014 Infiniti Q50 debuts G-replacing design, new hybrid model

Feast your eyes upon the all-new 2014 Infiniti Q50. Say what you will about Infiniti's new Q and QX naming system, but after looking at the new Q50 unveiled today at the Detroit Auto Show and checking out its feature list, we're having a hard time coming up with any additional criticisms. The highlights of the Q50, which goes on sale this summer in the US, include the eye-catching design, innovative cabin technology and a fuel-efficient hybrid model.
The Infiniti G has always had a focus on leading-edge styling, and its replacement is no different. We can easily see that the basic theme of the Q50 was inspired by the Infiniti LE Concept we saw earlier in the year. The edges are a little toned down for the production design, but the overall look is there with the fluidic lines, crescent-shaped C-pillar, the now-signature grille and the horizontal headlights and taillights. Compared to the current G Sedan, the Q50 is longer, wider and lower than its predecessor, and it's also more aerodynamic with a drag coefficient of just 0.26, putting in between the Chevrolet Volt (0.28) and the Toyota Prius (0.25).

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 Q50's novel drive-by-wire steering system recalled

The gradual replacement of mechanical components in automobiles with electronic systems brings with it definite advantages, but also poses certain potential dangers. Just think of the inevitable problems you've encountered with the computer on which you're reading these words and you'll know what we mean. But a computer crashing isn't as problematic as your car going on the fritz when its electronic systems fail.
That's what Infiniti is being reminded of with its new drive-by-wire electronic steering system. The Japanese automaker developed and installed the Direct Adaptive Steering System in its new Q50 sedan, but a small number of those cars on the road are now being recalled due to that system.
According to the National Highway Traffic Safety Administration, on a small number of examples, the Q50's optional by-wire system may fail if the temperature in the engine compartment drops below freezing. There's a backup mechanical setup in place should the electronic system fail, but NHTSA says that the backup system may also fail to engage in time to avoid a crash.
