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.

2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.

Nissan Sentra, Buick LaCrosse to headline LA Auto Show

We're less than a month away from the start of the Los Angeles Auto Show, and automakers have been lining up their debuts for the upcoming left-coast expo. The latest announcement comes from the show's organizers who are eager to tout the global debuts slated for next month. Chief among them will be new versions of the Buick LaCrosse and Nissan Sentra. So far all we've seen of the 2017 LaCrosse is a glimpse at the front grille, but it's already promising to bring elements of the Avenir concept to the street. The original LaCrosse was launched in 2004 and was replaced in 2010 with the current model. The Sentra nameplate has been around much longer, but the current model was launched more recently in 2013. The new version spied recently while undergoing testing is promised to be a substantial update on that model, not a complete replacement, bringing it up to speed with the latest equipment and revised styling. This represents the first official confirmation we've received of when Nissan will be unveiling the new Sentra. Mitsubishi will also be on hand with its new Outlander Sport, as well as the redesigned Mirage. They'll be joined as well by new versions of a couple of high-end models that promise to resonate with the local crowds in tinseltown. Land Rover has chosen the LA show as a suitable venue to unveil the production Range Rover Evoque Convertible that will drop the top on one of the most stylish luxury crossovers on the market. And Porsche, as we know, is gearing up to hit the track with the new Cayman GT4 Clubsport - a customer racing version of the company's little two-seat, mid-engined sports car that's been lightly modified for motorsport competition. Of course these won't be the only new metal on display at the Californian auto expo. They'll be joined as well by the likes of the new Infiniti QX30, Hyundai Elantra, Kia Sportage, and Jaguar F-Pace - many of which we've already seen. Meanwhile companies like Fiat, Ford, Mazda, Mercedes, Subaru, Volvo, Volkswagen, and Elio Motors are keeping their plans under wraps for the time being. But with mere weeks to go, it won't be long before we see what they've got in store as well.
