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 Q30 Concept might be the cleverest Q model yet

When we first got official word of the Infiniti Q30 Concept, the Japanese automaker said that the crossover's "harmonious contrasts and dissymmetric philosophy" would "make an emotional connection with customers spontaneously." Now, we might not be heads of design studios or directors of marketing departments, but we're pretty sure we can translate that to: "The production Q30 will compete with the Audi A3 and Mercedes-Benz CLA-Class."
In all seriousness (if we can say that of a concept car painted a sort of rose metallic), the Q30 concept looks fetching here in Frankfurt; its rather convoluted and flowing bodywork just carried off successfully because of its grownup hatchback proportions and, frankly, huge wheels. The Q30 could seemingly slot into the current, attractive Infiniti range of production cars and not look amiss (though we'd prefer a color palette that looks a little less like Grandma's sitting room sofa).
Look above for our live images of the Infiniti Q30 Concept from the show floor in Frankfurt, below for stock pictures of the thing, or scroll down to re-read the breathless press release.

2013 Infiniti IPL G Convertible

Infiniti rolled out the IPL version of its G37 Convertible at the Los Angeles Auto Show more than a year ago. The Infiniti Performance Line treatment logically mirrors that of the IPL G Coupe, meaning it receives both cosmetic and mechanical tweaks designed to raise the pulse of driving enthusiasts. Aside from the overstated aerodynamic styling components and huge exhaust tips, the cabin features special leather upholstery, aluminum trim and IPL badging to distinguish it from lesser siblings. Under the hood, the 3.7-liter V6 (VQ37VHR) has been recalibrated to deliver 343 horsepower - 18 more than the standard coupe - and 273 pound-feet of torque. The suspension has been upgraded with firmer spring and stabilizer bar rates, multi-piston sport brakes are fitted and 19-inch graphite-finish wheels wrapped with summer rubber are bolted on. There are only two exterior color choices (Moonlight White and Malbec Black) and two upholstery choices (Stone and IPL-exclusive Monaco Red). Everything sounds marvelous until someone reveals its as-tested $62,415 window sticker.
DRIVING NOTES
The three-section steel roof raises and lowers in a leisurely manner - give it about 30 seconds each way. While it is marvel to watch, the operation seems clunky, not fluid. Buttoned up, with all four windows closed, the cabin is comfortable. Wind noise is minimal and the front buckets coddle passengers in all the right places. While tight, those of smaller stature will find the two rear seats tolerable for short journeys (my kids never complained). Outward visibility is also very good for a convertible - no impeding B-pillar.
