Infiniti Q50 Eau Rouge Concept bows again, now with more GT-R [w/video]

Think back to the 2014 Detroit Auto Show and you'll remember the Infiniti Q50 Eau Rouge concept - a sedan that showed the potential design direction for a seriously high-performance take on the Japanese automaker's new entry-level luxury sedan. And while the show car we saw in Detroit was all well and good, it lacked something. Specifically, an engine. Kind of an important thing for a performance concept, right?
Here in Geneva, Infiniti rolled out that same Q50 Eau Rouge, but with one major modification: the sedan now boasts a twin-turbocharged 3.8-liter V6 under its hood - the same engine that's found in the Nissan GT-R supercar. In the Eau Rouge, this V6 is tuned to produce 560 horsepower and 443 pound-feet of torque, sent to the ground via the GT-R's all-wheel-drive system. Of course, this super-hot Q50 is still purely a concept, but Infiniti says that the potent engine underhood will allow the sedan to sprint to 60 miles per hour in less than four seconds, on its way to a top speed of over 180 mph.
The oft-fabled "four-door GT-R" still isn't confirmed for production, so for now, all we can do is cross our fingers (and toes). Check out the Q50 and its new beating heart in the gallery, above, and scroll below to hear what that potent Eau Rouge sounds like.

2023 Infiniti QX55 starts at $50,175, an increase of $2,650

Infiniti has added "more standard luxury amenities, driver-convenience features, and Infiniti Premium Care" to all grades of the 2023 QX55. The plusher digs come at a price, though. The entry-level Luxe and mid-level Essential trims have each gone up by $2,650, the 2023 Luxe costing $50,175 after the $1,025 destination charge, the 2023 Essential costing $55,275. The top Sensory trim has only been increased by $750, rising to $58,825. The dosh buys perforated leather upholstery, 4-way power lumbar adjustment for the driver's seat, a USB-C port for the back passengers, rear door handles with integrated LED welcome lighting, auto-folding heated outside mirrors with blind spot detection, and ProPILOT Assist across the board. Three-year standard maintenance program Infinity Premium Care is thrown in, too, providing routine inspections, oil changes and tire rotations for purchasers and lessees. Every variant also comes with wireless Apple CarPlay, but Android Auto still requires a cord. Moving to the Essential upgrades to adaptive LED headlights in a cube design with auto leveling, adds Traffic Sign Recognition to the ADAS suite, and extends feature content with items like climate controlled front seats, around-view monitor, and 3D building graphics for the navigation system. The QX55 Sensory picks up even nicer leather seating, four-way power lumbar adjustment for the front passenger, heated outboard seats in the second row, a heads-up display, and a motion-activated rear hatch. The powertrain holds steady with the 2.0-liter variable-compression four-cylinder making 268 horsepower and 280 pound-feet of torque, "shifting" through a continuously variable transmission and sending power to both axles. The 2023 QX55 can be configured at the Infiniti site now, arriving at dealerships sometime this summer.

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.
