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.

China's Geely buying majority stake in Lotus

Geely, the Hong Kong car company that owns Volvo, is acquiring control of British car company Lotus. Geely is purchasing a 51-percent stake in Lotus from struggling Malaysian car company Proton, and a 49.9 percent stake in Proton itself. Etika Automotive will gain the other 49 percent of Lotus. France's PSA Group and Japan's Suzuki had apparently also been interested in acquiring Proton. Geely says it plans to revive both Proton and Lotus. "The agreement lays the foundation for a wider framework for both Geely Holding, Proton and Lotus to explore joint synergies in areas such as research and development, manufacturing and market presence," Geely said in a news release. Those joint synergies will be highlighted by the lightweight chassis technology Lotus is known for, which could help Geely improve fuel efficiency. Geely CFO Daniel Donghui Li said the company aims to "unleash the full potential of Lotus Cars" by expanding and accelerating new products and technologies. Proton was nationally held but was privatized in 2007 to Malaysian conglomerate DRB-Hicom, which is owned by tycoon Syed Mokhtar Al-Bukhary. It was supposed to be the flagship for Malaysia's economic development.Though it owns two factories, Proton mainly rebadges foreign-made cars and sells them in Malaysia. What it has, what Geely presumably wants, is a distribution network in Southeast Asia to pit Chinese cars against Japanese automotive dominance in the region. Retaining a 50.1-percent stake in Proton is seen as a face-saving move. "Proton will always remain a national car and a source of pride, as Proton will still have a majority hold of 50.1 percent," Malaysian finance official Johari Abdul Ghani said. "Our very own much-loved brand now has a real chance in making a comeback, a huge one I hope." Related Video:

How Volvo is going greener, according to sustainability chief Henrik Green

STOCKHOLM — This week, Volvo unveiled its new flagship electric vehicle, the EX90 three-row SUV. ItÂ’s not just a look at a product weÂ’ll see come to market in 2024, but a glimpse at the approach Volvo is taking to become more sustainable as it aims to go all-electric by 2030 and carbon-neutral by 2040. After the unveiling of the EX90, we had the opportunity to speak with Henrik Green, VolvoÂ’s advanced technology and sustainability officer, as part of a roundtable discussion about the brandÂ’s climate strategy moving forward. Part of the strategy is accountability and transparency. In an industry where sensitive materials like cobalt and lithium can be environmentally, socially and geopolitically problematic, traceability is paramount. Volvo will use blockchain technology — the same sort of secure ledger tech that makes cryptocurrency possible — to trace cobalt, lithium and nickel from their very origins in the earth all the way to the EX90s that roll off the factory floor. Green said he expects that traceability to expand to more materials, but those three are what Volvo can commit to today. Green also predicts a time when “you as a consumer should be able to see, ‘Here, in my app, this is the car I bought, this is where my nickel came from thatÂ’s in my car.’” While step one is improving transparency, “the next step is — this is much more long-term — how can we affect the industry to source from the most sustainable sources as possible?” And that leads us to recycling. A circular economy is the goal, where raw materials are used minimally, replaced by materials sourced from old cars, batteries, electronics and the like. But that depends on the first generations of electric cars fulfilling their lifecycles before they can be recycled. And obviously the better the longevity of products like batteries, the longer this will take. “Unfortunately, it has this built-in time lag of putting batteries out there that live until they need to be replaced, and then we will get the material back.” Partners are beginning to scout for those recyclable materials from sources like non-automotive electronics, “but the massive volume of car batteries will not be accessible until these cars have been on the road 10, 15 or more years.” But recyclability is one of the main factors Volvo looks for when partnering with companies like Northvolt, with whom Volvo is building a factory and R&D center in Gothenburg, Sweden.
