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.

Nissan should kill the Quest and bring the Mitsubishi Delica D:5 to America

Enthusiasts don't have much reason to get excited about minivans. But if there were something cool to revitalize interest in the segment, I think American consumers would take notice. A quick browse through Mitsubishi's current catalog of global offerings turned up something interesting, and, now that Nissan has brought the diamond-star into its multi-headed global alliance, the Japanese automaker has a unique opportunity to throw caution to the wind and give America something fun. First, let's acknowledge that the Nissan Quest is a completely reasonable and current minivan entry. But it's not exactly a hot seller. The Quest was the seventh-best-selling minivan in the United States last month. The people-hauler's 209 sales in September of 2016 represent a 68-percent decline over the previous year. Granted, the Quest was trending upward for the year prior to last month's drop, but even the Quest's best full year of sales would just manage to match the number of Toyota Siennas or Chrysler Pacificas sold in a decent month. Put simply, the American market wouldn't miss the Nissan Quest if it were to disappear from dealership lots altogether. I don't think the Nissan Quest is a bad vehicle. The problem is that it's just like every other minivan sold in America. Nothing about the Quest stands out against its competitors, which basically makes it a redundant vehicle with no solid reason to exist. What Nissan really needs, in my humble opinion, is a minivan that stands out from the crowd. I offer the following solution: Bring the Mitsubishi Delica D:5 to the United States. Badge it as a Nissan to take advantage of that brand's larger dealer network; even call it the Quest Q:5 if you must. But don't change much else. I have a feeling Americans would show some interest in an eight-passenger, all-wheel-drive, multi-purpose vehicle like the Delica that's about the same overall length as the Nissan Rogue. As an added incentive to capture as many buyers as possible, offer both the 2.4-liter gasoline engine and the 2.2-liter four-cylinder turbodiesel that are available in other markets. Since the Delica D:5 is based on the same GS platform as the Dodge Journey, it could probably accommodate a Pentastar V6, too, but that doesn't really seem necessary. Instead of being a powerhouse, the Delica should be about fun and efficiency, with an adventurous off-road streak.

Race Recap: 2014 24 Hours of Le Mans defines 'endurance'

Commenting on the rush of events that rocked beginning and end of the 24 Hours of Le Mans, Paul Truswell of Radio Le Mans said "the race is about the ability to endure, not just the ability of drivers to do what they do for a long time." The entire race machine, all the way down to the pit boards and radios, has to survive the stress and abuse of the entire day. This was the race to prove those words.
There were two Toyotas, two Porsches and three Audis, five of the seven led the race at some point, six of the seven ran in the top three. Toyota will be hugely disappointed that it didn't win when its car and drivers were so, so strong, but they gave Audi the kind of scare we haven't seen since the best of Peugeot's days, and Toyota did a better job of it even in the loss. Porsche blew away everyone's expectations, falling 3.5 hours short of a fairy tale ending that would have made Disney cry.
But Le Mans doesn't really do fairy tales. Well, not that fairy tale. Audi's Twitter handle during the event was #welcomechallenges. As usual, Le Mans answered for the entire field.
