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.

We dialed a random Swede, talked about not driving Volvos

The Swedish Number is now a thing. It's a cool thing. You dial, a random Swede picks up, and you chat. Or, in my case, you dial and a random Brit living in Sweden for the past six year picks up and you chat. Since I was calling on behalf of Autoblog, when I got Martin from the small coastal town of Sundsvall, on the phone, we talked about cars, Volvos (natch), and cold-weather testing. Oh, and about plugging in his regular Toyota Prius. ABG: I was able to come to Sweden and test Volvos a month or so ago. Do you drive a Volvo? Martin: [laughs] No. I think Volvo is a fantastic car. It truly is an amazing car, but no. My girlfriend has a company car, so we drive a hybrid Toyota Prius. ABG: And how does that work in the cold winters? It obviously cuts down on the environmental problems. Martin: No problem at all. Because we have these cold winters, like you do get in the States as well, where we park our cars, we've got electricity posts where we can plug in the cars. Motor car engines have a heater, so you can have the heater going for some time before you get into the car. So it warms up the engine and there's a socket inside the car to warm up the inside of the car as well. It's very efficient. You just need to remember to set the timer when you climb out of the car and connect the cable. It obviously cuts down on the environmental problems as well because your car is already warm before you start them. ABG: I know that makes them overall more efficient, I just didn't know it could work with any car. It used to be you would keep the diesel engine blocks warm, but this works for pretty much any car in Sweden? Martin: Yes. Our temperatures here can vary. We do tend to get roundabout -18 to -25C [0 to -15F], where I live, sometimes. Normally, in the winter, we always plug the car in to make it more environmentally friendly, for starters, and then it's a nice warm car when you get in. The coldest I remember it getting here was -36 [-33F]. In the north of Sweden they've had, on record, -56 [-69F]. ABG: That's too cold. Martin: That is cold, yeah. Most countries, now, use the north of Sweden to test their cars because of the ice. Volvo S90 Prototype View 15 Photos ABG: That's actually why I came over there, to test out the new XC90s and S90s. Martin: Is that your job, then? ABG: I don't test the cars for the companies, but I test them for Autoblog. They'll invite us to test the vehicles so we can see for ourselves what the vehicles do in cold weather.

2018 Buick Regal TourX vs. wagon competitors: How it compares on paper

To the great joy of auto enthusiasts nationwide, wagons are back! Well, at least there's a few more of them. The latest is the 2018 Buick Regal TourX, which we just had our first drive of and found to actually be quite good with pleasant handling, solid power and plenty of space. But, how does the TourX compare to other cladded wagons? Well, let's dive into the specs and fire up the ol' spreadsheet maker for Buick Regal TourX vs Subaru Outback vs Audi A4 Allroad vs VW Alltrack vs Volvo V60 Cross Country. True, some are from mainstream brands and others are from luxury marques, but Buick straddles both realms, so it's appropriate to look at them all. Of course, there's more to these cars than just the numbers, but they're still important, and in the case of this class of crossover-aping wagons, can vary more than you'd expect. So check out the specs in the chart below, which are followed by more analysis and photos of each. Discover and compare other wagons and crossovers with our Car Finder and Compare tools. Engines and Transmissions When comparing powertrains, the Buick is far-and-away the winner as far as torque is concerned, and is in a nearly three-way tie for horsepower. Its 295 pound-feet of torque is 22 lb-ft more twist than the next-most-grunty Audi A4 Allroad. And in regards to power, the Buick's 250-horsepower engine is only down 6 hp to the most-powerful Subaru and its optional naturally aspirated flat-six, and just 2 hp less than the Audi. At the bottom of the pack is the Subaru Outback with the standard naturally aspirated flat-four, which only makes 174 hp and 174 lb-ft of torque. That may not seem too bad compared with the VW Golf Alltrack, which only makes 170 hp and 199 lb-ft of torque, but the VW is much lighter by between 200 and 300 pounds. Transmission-wise, there's quite a bit of variation in the group. The Regal TourX and the Volvo V60 Cross Country rely on eight-speed automatics, all Outbacks use CVTs, and the Alltrack and Allroad have dual-clutch automated manual transmissions with six and seven gears, respectively. But for people that want to shift for themselves, the only option is the Volkswagen, which offers a traditional six-speed manual transmission on the Golf Alltrack. Cargo and Interior Space One of the main reasons to buy a wagon is for the body style's large cargo capacity. And for the most space for things and stuff, you'll want to check out the Subaru and the Buick.
