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 Brazilian Grand Prix is the same as it ever was

At this point, we hope Nico Rosberg is planning to carry his current qualifying form into the 2016 season and back it up with the same kind of race-day cojones he showed winning the race in Mexico City two weeks ago. The Mercedes-AMG Petronas driver got it right enough again on Saturday afternoon to take his fifth consecutive pole position ahead of teammate Lewis Hamilton by almost a tenth of a second. It's the same one-two from Brazil last year. The bad news for the rest of the field is that the winner in Brazil the last seven years has been one of the two drivers on the front row. Last year it was the Williams duo that lined up behind Mercedes, this year it's Ferrari. Sebastian Vettel plays the stalking horse, securing third in his Ferrari ahead of teammate Kimi Raikkonen in fourth. Williams driver Valtteri Bottas actually qualified in fourth, but he had to serve a three-spot grid penalty for passing under red flags in Free Practice 2, so he started sixth. That promoted Sahara Force India driver Nico Hulkenberg up to fifth. Daniil Kvyat was the quickest representative from Infiniti Red Bull Racing, getting into seventh even with a Renault power unit that's weak on some of the key stretches at the Interlagos track. Felipe Massa had the second Williams in eighth, in front of the second Red Bull driven by Daniel Ricciardo in ninth. Toro Rosso hasn't confirmed its drivers for next year but Max Verstappen keeps making it hard to look elsewhere, taking 10th. Rosberg is working nearly the same trick he pulled last year: drive like a second driver for most of the year, drive like a world champion for the last quarter of a season. He pulled away at the start and covered Hamilton just enough on the run to the first corner to keep Hamilton on the outside. By the end of Turn 1 the German had the lead and didn't give it up for the rest of the race outside of pit stops. Without overwhelming pace to pass and unable to follow closely, Hamilton could do nothing except ask his team for a different strategy to go for the win. When Mercedes told him "No," trying to protect Rosberg's second place in the championship ahead of Vettel, that was the race. Just like last year, Rosberg and Hamilton finished one-two. Vettel, Raikkonen, Bottas, Hulkenberg, and Kvyat drove lonely races to finish in positions three through seven.

2019 Infiniti QX50 Essential Drivers' Notes Review | Variable impressions

The 2019 Infiniti QX50 is the brand’s second smallest crossover, and itÂ’s fully redesigned for the 2019 model year. Infiniti decided to use the stylish QX50 as a technology flagship, specifically using it to debut its variable-compression engine technology. It has since been shared with Nissan in the new Altima, but Infiniti got the new 2.0-liter turbocharged four-cylinder first. It makes a solid 268 horsepower and 280 pound-feet of torque, numbers that are very similar to the outgoing QX50Â’s 3.7-liter V6. However, the 2019 QX50 with all-wheel drive (as our tester is equipped) nets you 26 mpg combined to the old carÂ’s 20 mpg combined rating. Infiniti pairs the new engine with its continuously-variable transmission. We happen to be testing the absolute pinnacle of what a QX50 can be: the “Essential” trim level. The base QX50 Pure starts at $37,645, whereas ours towers up to $59,085. That steep price is thanks to the addition of several high-dollar packages, including the $7,500 Sensory Package. This is the price youÂ’ll pay to get the ultra-luxe interior that we happened to fall in love with. The Autograph Package added $2,000, netting us white leather with the blue suede accents. Then the ProActive ($2,000) and ProAssist ($550) packages provide all the advanced driver assistance features like ProPilot Assist. Take note that the frustrating steer-by-wire (DAS) system is also included in the ProActive Package. Assistant Editor, Zac Palmer: When fully optioned as our QX50 Essential tester is, this interior can mix it up with the best in the business. You may have to sell a kidney to afford it, but the quilted white semi-aniline leather, soft blue suede and light maple (real) wood is going to make it all worthwhile. Infiniti certainly nailed it on the materials, but the interior design and styling flourishes are executed just as successfully. There's a simplicity to the flatness and gently curving horizontal lines that feels so graceful and luxurious. I feel that I'd never tire of the cream, brown and blue color combination, though that light-colored leather means I'd forever be trying extra hard to keep it clean. All of this interior loveliness was almost enough to make me forget about this crossover's interior tech shortcomings. Infiniti hasn't integrated Apple CarPlay or Android Auto, and the stock infotainment system isn't nearly polished enough to warrant such an omission.
