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.

AB Volvo to build trucks using steel forged without fossil fuel

STOCKHOLM — Swedish truck maker AB Volvo and steel maker SSAB have signed an agreement to produce the world's first vehicles made of fossil-free steel, the companies said on Thursday. Volvo plans to start production this year of prototype vehicles and components from steel made by SSAB using hydrogen produced from renewable energy. Small-scale serial production will start in 2022. "This is an important step on the road to completely climate-neutral transport," Volvo CEO Martin Lundstedt said. The vehicles and machines will be emissions-free in operation, Volvo said, without specifying how they would run, while adding the company is reviewing all the materials used in their construction to eliminate anything based on fossil fuels. It will be sourcing steel from green steel venture HYBRIT — which is owned by SSAB, Swedish state-owned utility Vattenfall and Swedish miner LKAB. Last August, it began test operations in Lulea, Sweden, to replace coking coal, traditionally needed for ore-based steel making, with fossil-free electricity and hydrogen, which in turn is produced using only renewable power. [L8N2FX3LV] China's Geely Holding, which has a stake in AB Volvo, owns Volvo Cars, which it has said will be fully electric by 2030.
