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 invests in sailing ships to reduce its carbon footprint

Renault is taking a page from the golden age of sailing as the company looks towards reducing its carbon footprint through the use of cargo sailing ships. The French automaker recently announced its partnership with Neoline, a start-up enterprise based in the west of France. The firm specializes in reducing the cost and emissions of typical cargo ships, by reintroducing sailing into the transportation equation. Renault's goal is to reduce its global carbon footprint by 25 percent in 2022, as compared to where they were in 2010. This plan also includes a separate target, to lower supply chain emissions - which includes shipping methods such as trucks, trains, and cargo ships - by 6 percent, compared to levels in 2016. Two prototype cargo vessels, complete with a full set of sails, will be introduced by 2021-22. These two ships will travel between the U.S. eastern seaboard (exact locations are TBD) and the French port cities of Saint-Nazaire and Saint-Pierre & Miquelon. Specifics about what exactly the ships will be carrying has not been released, though Renault is part of an extensive global auto alliance that includes Nissan and Mitsubishi. "For nearly 10 years, we have been working to identify the most environmentally sustainable solutions," said Jean-Francois Salles, Alliance global director, production control. "For example, optimizing the fill rates of the containers and trucks, producing eco-friendly packaging, and implementing a multi-modal system." The current demonstration vessel measures in at 446 feet in total length and has more than 45,000 square-feet of sail. For all you big ship fans out there, the Titanic was about double this size, stretching about 882-feet in length. When powered solely by the wind, Neoline CEO, Jean Zanuttini, says that total emissions drop by as much as 90 percent, versus the carbon footprint of a traditional cargo vessel.

Ousted Renault CEO Bollore raised concerns over Ghosn investigation

PARIS — Renault's former chief executive Thierry Bollore, who was ousted in October, had sought to flag alleged conflicts of interest and governance problems at the company's Japanese alliance partner Nissan before his departure, Le Monde reported on Monday. Citing a letter from Oct. 7 addressed to Nissan's board, of which he was member, France's Le Monde newspaper said Bollore had raised questions over the firm's internal investigation surrounding former alliance boss Carlos Ghosn. Nissan and Renault were left reeling by Ghosn's arrest in Tokyo a year ago, on financial misconduct charges which he denies. They have since tried to reboot their strained partnership by revamping their management teams, including by purging them of Ghosn allies and removing people in top jobs at the time of the scandal. Bollore — who took a step up at the French carmaker when Ghosn left even though he was known for his close ties to the alliance founder — was eventually pushed out as Renault's CEO on Oct. 11, days after penning his letter. In comments sent to Reuters, Nissan spokeswoman Azusa Momose denied there were any irregularities in its internal investigation of Ghosn's affairs, and added that the company had reviewed its processes once again following Bollore's letter. "Nissan's independent directors confirmed that the investigation was properly conducted and could be relied on," Momose said. Nissan directors had discussed all the allegations raised by Bollore and the company "concluded that Bollore's concerns were not founded and were based for the most part on inaccurate information and speculation," she added. Bollore said in the letter that he was particularly concerned by the revelation that Nissan had a list of 80 managers implicated in financial dealings similar to the ones attributed to Ghosn. He also raised issues with the chain of command at Nissan, saying some key board members were sometimes kept in the dark on internal matters. Renault, which is still searching for a permanent replacement for Bollore as CEO, had no immediate comment. As well as changing its CEO, Nissan recently demoted senior vice president Hari Nada — a key whistleblower against Ghosn and whose role was also questioned in Bollore's letter — although its internal investigation had found no evidence against the executive.
