Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.

Next Nissan GT-R to take cues from GT-R LM Nismo Le Mans entry

For those wondering why Nissan named its coming Le Mans Prototype the GT-R LM Nismo, colliding the two worlds of sports car and prototype racing, an article in Autocar might have the answer. The deeper union is explained by saying that the next-generation GT-R will use "hybrid technology that will closely align it" with the GT-R LM Nismo.
The point could be further driven home by the fact that the GT-R LM Nismo will begin its FIA endurance racing campaign next year, and the next GT-R is due to debut next year as a 2016 model. The expectation is that it will use a hybrid system possibly dubbed R-Hybrid and perhaps developed by Williams. Just like performance car makers Ferrari and Audi, Nissan wants its racing efforts to pay off with road car technology, company vice president Andy Palmer saying they "want to link technological linkages between future evolutions of the GT-R and evolutions of what we do in LMP1, and the two do go in both directions."
The bigger question is, with the GT-R getting hybrid assistance, will it also get the weight gain that usually comes with it? Enthusiasts would love to see the trend reversed, especially on a car that's already no lightweight.

Renault board names Ghosn stand-ins, as tensions with Nissan increase

PARIS/TOKYO — French carmaker Renault tapped its chief operating officer and a senior board member to fill in for embattled boss Carlos Ghosn, after an investigation by alliance partner Nissan led to his arrest on suspicion of financial misconduct. Thierry Bollore, Ghosn's operational second-in-command, will become deputy chief executive, while lead independent director Philippe Lagayette assumes the function of interim chairman, Renault said after a board meeting late on Tuesday. But the board refrained from firing Ghosn while awaiting more detail on the allegations — in a decision that could also buy more time for an accelerated, permanent succession process. "Mr. Ghosn, temporarily incapacitated, remains Chairman and Chief Executive Officer," Renault said in a statement. "During this period, the board will meet on a regular basis under the chairmanship of the lead independent director." Ghosn, one of the car industry's best-known leaders, was arrested on Monday after Nissan said he had engaged in years of wrongdoing, including personal use of company money and under-reported earnings. The Japanese company plans to remove him as chairman on Thursday. The French government, Renault's biggest shareholder, had begun to distance itself from Ghosn, calling for new interim leadership before the meeting, as the Japanese investigation expanded to include Renault-Nissan alliance finances. "Carlos Ghosn is no longer in a position where he is capable of leading Renault," Finance Minister Bruno Le Maire said earlier in the day. "Renault has been weakened, which makes it all the more necessary to act quickly." Statements by Le Maire, Renault and its board all echoed French preoccupations over the future of the alliance first articulated by President Emmanuel Macron within hours of Ghosn's arrest on Monday. Following talks between Le Maire and his Japanese counterpart Hiroshige Seko on Tuesday, the ministers reaffirmed their "shared wish to maintain this winning cooperation." But in a sign that Nissan may now seek to loosen its French parent's hold on the partnership, the Japanese company informed Renault it also had evidence of potential wrongdoing at Renault-Nissan BV, the Dutch venture overseeing alliance operations under Renault's ultimate control, three people with knowledge of the matter told Reuters.
