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.

Here's today's round of auto plant closures in response to coronavirus

More automakers have shuttered factories, as businesses everywhere work to slow the spread of the Covid-19 coronavirus — and as the pandemic slows sales and disrupts parts supply chains. On Friday, the following closures were announced: • Volvo will close its factories in Sweden and the United States from March 26 to April 14. Volvo's U.S. facility, in Charleston, South Carolina, makes the S60 sedan. Its assembly plant in Torslanda, Sweden, turns out the XC90, SC60, and V90. Other Swedish facilities make engines and component parts. A Volvo factory in Ghent, Belgium, that builds the XC40 and V60 closed earlier this week and is expected to remain offline until April 6. Volvo's four factories in China have been reopened after a shutdown earlier this year. • Jaguar Land Rover announced that it will suspend production at its assembly plants in the UK over the coming week. The shutdown is expected to last until April 20. Elsewhere, production continues at the company's factories in India and Brazil, and JLR's joint-venture plant in China reopened at the end of February. • Bentley is closing its factory in Crewe, England, for four weeks, effective today. • Bugatti has put its atelier in Molsheim, France, on hiatus. No date was given for when assembly of its supercars might resume. • Mercedes-Benz on Monday will shut down its SUV factory in Alabama and its van assembly plant in South Carolina. Both will remain closed for a minimum of two weeks. Tesla yesterday revealed that it will suspend operations at its Fremont, California, vehicle assembly plant next week, on order from local officials there. Yesterday's factory closure announcements also included the U.S. assembly plants for Toyota (until April 6), Volkswagen (through March 29), Subaru (through March 29), and Hyundai (no time period specified). They join GM, Ford, Chrysler, Honda, Nissan, and Harley-Davidson, which earlier this week announced the suspension of production at their facilities.
