Infiniti teases G-replacing Q50 ahead of Detroit debut

Preparing for the introduction of its new naming system and redesigned entry-level sedan, Infiniti has released a brief teaser video for the 2014 Q50. As a refresher, the Q50 is the replacement for the G37 sedan, and while we've seen spy shots of this car before, this video is our first detailed look at the production car.
All we get to see in the video is a shot of the headlight, but we get to see key elements like the stylish daytime running lights, crescent-shaped parking lights and adaptive low beams. The overall shape of the headlight is very close to what we saw earlier this year on the LE Concept. We have to wait until the Detroit Auto Show kicks off in a couple weeks to see the Q50's full design (although we're sure there will be some leaks before that point), but until then, check out the short video posted after the jump.

Infiniti Q80 Inspiration Concept previews a fullsize future of luxury

Well, this certainly looks like a concept, doesn't it? From the wide, portal-esque door opeings to the boattail rear window design, there's just so much about the Infiniti Q80 Inspiration that looks like it would never actually reach production that we're impressed the automaker had the gumption to put the machine together and show it off at the 2014 Paris Motor Show.
This marks the first time that Infiniti has shown any sort of real intent to enter into the rarefied air of the fullsize luxury sedan segment, populated as it is by the likes of the Audi A8, BMW 7 Series and Mercedes-Benz S-Class. Those are extremely heavy hitters to market against, and Infiniti sounds anxious to throw its hat in the ring.
"We aim to do this with elegance, style, and emotion," says Francois Bancon, Infiniti Vice President, Product Strategy. "This car is making a statement. Q80 Inspiration is a precursor of a production model in this segment and, as such, integral to our future."

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.
