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.

Volvo-based Futuricum electric truck sets Guinness range record

There is a new Guinness World Record for the longest distance traveled by an electric truck on a single charge. Swiss-based firm Futuricum built a Volvo-based delivery truck that drove for 683 miles on a closed test track. Although the prototype used to set the record has reportedly been in regular service on Swiss roads since early 2021, the record was set on a 1.7-mile high-speed oval operated by Continental near Hanover, Germany. The truck set off with a full charge and coasted to a stop 392 laps later; two drivers split their schedule in 4.5-hour shifts. Reaching the 683-mile threshold took about 23 hours, so the truck traveled at an average speed of 31 mph. Futuricum calls this a realistic average value for the truck's intended use — it's certainly not designed for long hauls. Whether it was empty or loaded with cargo wasn't specified, and we've reached out to the company for more details. What we do know is that the drivetrain was not modified, meaning the 680-horsepower truck is equipped with a 680-kilowatt-hour lithium-ion battery pack. That's over six times bigger than the battery in a Porsche Taycan. Driving at a constant speed on a closed track is very different than delivering parcels in real-world conditions, which is what the Futuricum truck normally spends its days doing. In more normal use cases, the model (whose speed is electronically limited to about 55 mph) has a driving range of around 250 miles, according to the manufacturer.

Volvo shuts down Gothenburg plant due to chip shortage

STOCKHOLM — Volvo Cars, owned by China's Geely Holding, will temporarily stop production at its Swedish plant in Gothenburg due to the shortage of semiconductor chips, it said on Wednesday. A global chip shortage has hit manufacturing, with automakers cutting down on production and electronic device makers struggling to keep up with a pandemic-led surge in demand for phones, TVs and gaming consoles. "Production at Torslanda will be paused temporarily from this evening due to a material shortage linked with the semiconductor issue," Volvo Cars said in an emailed statement. "Production will restart as soon as possible, at the latest before next week," the Swedish carmaker, which in June halted production at its Belgian plant in Ghent for a week, said. Volvo Cars, which last month reported a return to profit in the first half as demand for electric cars grows, is considering listing on the Nasdaq Stockholm stock exchange this year.
