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 reveals 400-hp twin-charged PHEV power for new XC90 [UPDATE]

UPDATE: An earlier version of this post indicated that the larger of the conventional diesel engines was a five-cylinder. However all three powertrains announced for the upcoming new XC90 are actually four-cylinder engines. The text has been updated accordingly.
Volvo rolled in to new territory when it introduced the original XC90 back in 2002, creating its first SUV and one of its top-selling models. But that was 12 years ago. In the meantime it's followed up with the smaller XC60, but what the brand faithful and the industry at large have been looking forward to most is the arrival of the new XC90.
Previewed by the Concept XC Coupe at the Detroit Auto Show, the new XC90 is set to arrive later this year, but to keep us on our toes, the Swedish automaker has been steadily trickling out a stream of information and photos. Two months ago it gave us a glimpse inside the cabin, and last month it revealed its new infotainment system, but now Volvo has released details on the upcoming new XC90's powertrain.

Volvo promises new direct-injected diesels, 8-speed auto

As a part of eliminating its dependence on Ford platforms and powertrains, Volvo has previously announced information about its Volvo Engine Architecture (VEA) and Scalable Platform Architecture (SPA), but now we're finally getting some details about what will power some of the Swedish automaker's next-generation products.
The biggest key to VEA on the diesel engines is a new technology Volvo calls i-ART. This system uses unique injectors at each cylinder capable of monitoring fuel pressure and adjusting accordingly to maximize fuel economy and performance and reduce emissions. Looking ahead, Volvo says its four-cylinder engines will be able to offer the power of a six-cylinder and eventually, mixed with some sort of electrification, will be able to rival the performance of a V8 and "turn V8s into dinosaurs."
More details about the new diesel injection technology is posted in the press release below.
