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.

2015 Infiniti QX80 gets a minor refresh, fancy new trim

Infiniti revealed an ever-so-slightly refreshed QX80 alongside its Q70 luxury sedan this morning in New York. The biggest news for the brand's fullsize SUV is the addition of a range-topping trim level, unimaginatively dubbed the QX80 Limited.
The Big 80 sports a couple of styling tweaks in an effort to bring its appearance more in line with the brand's current design language. The "double-arch" grille with mesh inserts we first viewed on the Q50 now adorns the front fascia, and the head and taillights have gone full-LED. Still, it's hard to call this SUV anything but ugly. It's bulbous and almost brutish, which aren't generally words you want to have to use when talking about any kind of luxury vehicle.
There aren't many updates inside or to the drivetrain, either. Like the Q70, Infiniti has added a couple of new tech features, such as its Predictive Forward Collision Warning system and High Beam Assist. Although it's getting a bit long in the tooth, the interior remains nice, with lots of wood and leather all around. The SUV continues to use a 5.6-liter V8, which produces 400 horsepower and 413 pound-feet of torque, mated to a seven-speed automatic transmission.

2014 Infiniti Q50 priced at $37,605*

Infiniti has released full pricing information for its new 2014 Q50 line, which, as you're probably aware, replaces the well-liked G-series sedan. You may be wondering why this is news, as Infiniti announced pricing for its new Q50 sedan back in March. Apparently, though, those earlier prices applied only to the special pre-sell offer announced earlier this year and are only good for cars ordered by October 31, 2013.
Starting in November, base 2014 Q50 models with the automaker's 328-horsepower 3.7-liter V6 engine will begin at $37,605 (*including a $905 destination fee), while the sportier Q50S model will begin at $44,105. Adding all-wheel drive to either model costs an additional $1,800 over the standard rear-wheel-drive models. Regardless of engine or whether it's rear- or all-wheel drive, the Q50 comes with a seven-speed automatic transmission.
Opting for the 2014 Infiniti Q50 Hybrid will get the buyer a powertrain consisting of a 3.5-liter V6, a 50kW electric motor and a lithium ion battery that offers up a total power output of 354 hp and a highway fuel mileage rating of 36 miles per gallon, all for a starting price of $44,855, which includes the Premium group. The most expensive version of the new sedan is the Q50S Hybrid with all-wheel drive. That model carries an MSRP of $49,055.
