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.

Cadillac reveals stretched ATS-L in China

In the market for a new Cadillac, but need more space than an ATS can afford? Then you'll want to look at the larger CTS. Unless you live in China, where buyers - often chauffeured instead of driving themselves - seem to prefer a long-wheelbase version of a smaller sedan than upgrading to a larger one. For those buyers, Cadillac has released the new ATS-L.
Based on the existing ATS sports sedan, the ATS-L offers an extra 3.3 inches of rear legroom over the model we get here. As a result, the ATS-L stretches its wheelbase to 112.5 inches and its overall length to 186 inches, while riding a quarter-inch lower than the standard-wheelbase model, which itself was recently updated. That places its length in between the regular ATS and the CTS available Stateside.
Otherwise it's essentially the same sedan, but appears to ditch the base 2.0-liter four to offer either the 2.0-liter turbo four or 3.6-liter V6. Of course this model, produced locally for the Chinese market, isn't likely to make the transpacific voyage to US showrooms, so American buyers will still have to choose between the standard ATS, the larger CTS or the even larger XTS.

Cadillac CT6 to be lighter than CTS, get PHEV model

Cadillac is suddenly one of the most talked about automakers in the US with Johan de Nysschen taking control. The brand claims that it eventually wants to become, once again, the standard of the world. One of the first vehicles to actually prove whether that's possible is its upcoming CT6 flagship sedan. We still don't know what the production version looks like undisguised, but other important details are falling into place. The latest big news sheds some light on the Caddy's powertrain and some estimates of its weight and size.
General Motors product chief Mark Reuss dropped the details at the automaker's Global Business Conference. According to The Detroit News, he revealed that the CT6 would use a twin-turbocharged, 3.0-liter six-cylinder engine with an eight-speed automatic transmission, and a plug-in hybrid would be an additional option. He reportedly claimed it would be the most "powerful six-cylinder gas engine in the segment" and said the hybrid could get around 70 miles per gallon.
Reuss also revealed that the CT6 would be about 53 pounds lighter than the current CTS, despite being about 8 inches longer, according to The Detroit News. If that's the case, the new flagship is about 203.5-inches long, which is 1.5-inches more than the XTS.
