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.

Renault, Nissan limit French government interference

Renault and Nissan are taking action to limit the influence that one can exercise over the other's operations. The measures, announced by both automakers after meetings of their respective boards in Paris and Tokyo, aim to keep each other at arm's length. But more than that, they seek to cap the degree of influence which the French government can bring to bear on either automaker. The steps are being taken in response to investment moves by the French state. While the government's investment arm – known as the Agence des Participations de l'Etat (or state participation agency) – previously controlled 15 percent of Renault's shares, it increased its holdings this April to 19.73 percent. The action sparked concerns at Renault that the French government would attempt to dictate operating procedures to both automakers, potentially to favor production in France over other locations. Given that Renault holds a 43-percent stake in Nissan, the Japanese automaker grew concerned over potential French state interference as well. To assuage those concerns, Renault, Nissan, and the French government came to an agreement with three vital clauses. Most importantly, despite its nearly 20-percent holdings, the French government will be granted only 17.9 percent of voting rights in Renault (to be extended up to 20 percent under certain exceptional circumstances). Renault (and by extension the French government) will also be prevented from interfering in Nissan's governance. With those measures in place, Nissan will not seek more voting rights based on the 15-percent stake which it, in turn, holds in Renault. Having successfully concluded the deal and hedged against the threat of government interference, the Renault board reasserted its confidence in Carlos Ghosn. Through the unique terms of their alliance, Ghosn serves as chairman and CEO of both Renault and Nissan. The two cooperate closely and share resources extending far beyond their chief executive, but remain distinct companies rather than merge, as Fiat and Chrysler have. Renault Board approves alliance stability covenant between Renault and Nissan As early as 16th April 2015, the Renault Board of Directors unanimously reiterated that the sustainability, success and resilience of the Alliance since its very inception in 1999 were based on a balance of shares held by Renault and Nissan.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
