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.

Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.

NHTSA urges owners of recalled Takata airbag vehicles to take immediate action

The National Highway Traffic Safety Administration and the Department of Transportation are taking the unusual step of issuing a followup press release urging owners of certain recalled vehicles "to act immediately" to fix their cars and trucks. The problem in question concerns the repair campaigns for rupturing Takata airbag inflators issued in June and covers a long list of models from Toyota, Lexus, Honda, Acura, Mazda, BMW, Nissan, Infiniti, Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac.
While NHSTA doesn't specifically say why the recall is vital in the new release, Toyota's own explanation in its newly announced renotification campaign earlier today sheds some new light on the topic. According to the Japanese automaker, in testing, Takata found a possible link between the rupturing airbag inflators and high humidity. NHTSA is advocating that all owners pursue repairs immediately if they haven't already done so already. This is especially crucial for those drivers especially in Florida, Puerto Rico, Guam, Saipan, American Samoa, Virgin Islands and Hawaii because of the humid conditions there.
We don't need to tell you how dangerous an inadvertent airbag deployment could be - even in a stationary vehicle - but adding to the Takata issue is fears that the deployment could lead to shrapnel being sprayed into the cabin.
