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.

2022 Infiniti QX50 starts at $40,025

Infiniti upped prices on the 2022 QX50, but at least some of the MSRP increase goes toward new features. Nissan's luxury arm made ProPilot Assist standard for all five trims, the driver assistance suite includes tech like steering assist, intelligent cruise control, speed limit assist, and distance control assist. Apple CarPlay is another included item for next year's model, as well as an auto-dimming rearview mirror, and more soft-touch luxuries for the rear quarters with keyless entry able to be activated by the rear doors now, LED welcome lights in the rear door handles, and a USB-C port for the aft chairs. The first four grades are front-drivers; adding all-wheel drive adds $2,000 to the tab. For 2022, top front-wheel drive Autograph bows out, making AWD the de facto standard. The trims and their pricing after the $1,025 destination fee, plus their differences from the 2021 model, are: Pure: $40,025 ($950) Luxe: $43,375 ($750) Essential: $47,825 ($2,000) Sensory: $52,525 ($1,400) Autograph AWD $57,975 (no change) On top of the other newly standard equipment, the Essential trim picks up a heated steering wheel, 16-speaker Bose Performance Series audio, climate-controlled front seats,  Luxe fits "leather-appointed seats," and offers an updated Appearance Package for $1,200. The bundle is composed of black mirror caps, body color rear diffuser, black mesh grille, black fender accents, a black liftgate finisher, and 20-inch black-painted, machine-finished wheels. A graphite headliner finishes the package inside.   Sensory snares some features formerly reserved for the Autobiography, like "leather-appointed" perforated seats, four-way passenger power-seat lumbar adjustment, heated outboard seats in the second row, ultrasuede interior trim, and a motion-activated liftgate.  The eight-strong color palette welcomes a new Slate Gray hue. Mechanicals don't change, every model powered by a 2.0-liter inline-four cylinder with 268 horsepower and 280 pound-feet of torque, routing its output through a continuously-variable transmission. The 2022 Infiniti QX50 should reach dealers later this month.

2014 Infiniti Q50S

Ten years ago, nearly to the day, I took delivery of a brand-new 2004 Infiniti G35 6MT. The sporty rear-wheel drive sedan, equipped with its throaty 260-horsepower V6, slick manual gearbox and limited-slip differential replaced my 2001 BMW 330i because the Japanese competitor touted a product that was roomier, better equipped, quicker and lower priced. The G35 trumped the German in nearly every measurable category - at least on paper.
The 2014 Infiniti Q50 is the direct descendant, albeit two generations later, of the car I owned a decade ago. It is dimensionally about the same size, but it has gained more than 300 pounds of mass thanks to numerous safety upgrades and technical innovations. The additional weight is largely dismissed by a larger and more efficient powerplant that delivers an additional 68 horsepower, a welcome arrival, but the manual gearbox that charmed enthusiasts has been pushed out of the picture by a mandatory seven-speed automatic transmission.
As it has in the past, Infiniti touts its all-new Q50 as a luxury sport sedan worthy of the title. Decades ago, impressive performance statistics may have sealed the deal. Yet there is much more to the assignment today, as the model must offer premium appointments, sophistication and engaging driving dynamics if it's going to entice and capture the next-generation of young, premium buyers - much like the G35 did for me ten years ago.
