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.

Regulators consider adding more carmakers to Takata recall

Volkswagen's diesel emissions scandal has been getting a lot of press recently, but the Takata airbag inflator affair could be grabbing headlines again soon. According to Bloomberg, the National Highway Traffic Safety Administration is contemplating an expansion to the campaign that could add seven automakers to the 12 already affected. They are Jaguar Land Rover, Mercedes-Benz, Spartan Motors, Suzuki, Tesla, Volvo Trucks, and VW Group. To be clear, there's no recall for any of these automakers, yet. The government is simply asking for a full list of vehicles that each of them have with Takata-supplied inflators containing ammonium nitrate propellant. The agency is concerned this substance could play a roll in the ruptures. "NHTSA is considering not only whether to issue an administrative order that would coordinate the remedy programs associated with the current Takata recalls, but also whether such an order should include expansion of the current recalls," the letters say. All seven can be viewed, here. From a report supplied by Takata, the government already knows that the company supplied 887,055 inflators with ammonium-nitrate propellant to VW and 184,926 of them to Tesla. In an incident during the summer, a side airbag allegedly burst in a 2015 VW Tiguan. In early September, NHTSA put out a revised report that there were 23.4 million inflators to be replaced in 19.2 million vehicles in the US. An earlier accounting from the agency had about 34 million of the parts in 30 million cars. High humidity is still believed to be among the biggest risk factors for the ruptures. Although, if ammonium nitrate also gets the blame, some already recalled models might need to be repaired again. Related Video:

Volvo V90 Cross Country vs V60 Cross Country Luggage Test | Comparing cargo areas

While the Audi A6 Allroad and Mercedes E 450 All-Terrain have disappointed us with their poseur levels of capability and questionable value, that is not the case with the other midsize luxury off-roadish wagon: the 2021 Volvo V90 Cross Country. It has genuinely useful extra ground clearance and a lower, more sensible price. But what about that other element of wagon goodness, utility?  Although I have not luggage-tested the Allroad or All-Terrain, Road Test Editor Zac Palmer effectively did so using different luggage and different A6/E-Class wagon variants. Our results are therefore only vaguely comparable. My guess is the Mercedes would win the day and the V90 would top the Audi, but again, that's just a guess. I have, however, luggage-tested Volvo's smaller off-roadish wagon, the V60 Cross Country. Surprisingly, the difference between Cross Countries isn't that great.  According to Volvo's wonderfully detailed cargo specifications that indicate what exactly they measured (hint hint, every other car company), the V90 Cross Country (above left) has 25.5 cubic-feet of space behind the back seat from floor to roof. The V60 Cross Country (right) has 23.2 cubic feet. That's not much of a difference.  However, Volvo also provides the cargo area length from the seat base to the liftgate. That's a bigger difference on paper: 45.4 inches for the V90 and 40.7 inches for the V60. That would play out once I brought the luggage into the equation.  Before we get to the bags, though, take one more look at the above comparison photo. Check out the different D pillars and specifically how much more upright the V60's are. That's my guess as to why the V90 cargo area manages to be so much longer, yet has only a minor volume difference.  Same bags, same formation, different Volvo wagons. You clearly see here that there's more length available in the V90. Five inches more? I don't know about that, but you nevertheless DO get more space.  As with every luggage test I do, I use two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D).
