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.

Recharge Wrap-up: Infiniti considers EV for China, NextEV hires former Tesla, Apple engineer

NextEV has hired Tesla Autopilot and Apple veteran Jamie Carlson as Senior Director of Advanced Technologies. The seasoned autonomous driving engineer joins fellow former Autopilot engineer Kurt Thywissen, who is now NextEV Senior Director of Human-Machine Interaction. NextEV, which is working on an all-electric supercar before focusing on mainstream EVs, recently obtained a self-driving car permit from California and opened its North American headquarters in San Jose.

"When I think about EV, we design it for China definitely, even as the first market to launch," says Infiniti President Roland Krueger. "We are discussing this internally constantly what is the right timing for Infiniti to have such vehicles." Infiniti has held back on launching an EV, focusing instead on hybrids, but says it could be "very fast" in deploying an EV once it decides to do so. Having Nissan and Renault backing Infiniti, the luxury brand is confident about its access to proven EV technology. Read more at Automotive News Europe. Thrifty car rental has added a Tesla Model S to its fleet in Canberra, Australia. Available at the Canberra Airport, it's the first luxury EV offered for rent from a mainstream rental company in Australia. Australia's capital offers a small registration discount and no stamp duty for EVs, making it a cheaper and more practical place to locate the country's first rental Tesla. Thrifty's parent company, NRMA, is calling on Australia's other states and territories to remove financial and regulatory barriers to EV technology. Read more at The Motor Report.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.
