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.

2016 Nissan Sentra to get heavy restyle

Nissan is having a banner year when it comes to launching updated products in 2015. The latest Maxima is already on sale in showrooms, and the next-gen Titan joins it later. Refreshes for the Sentra (2014 model year pictured above) and Altima are also on the way, and the changes are likely to be significant to stay competitive in the compact sedan segment. "It will be an incredibly freshened Sentra," Fred Diaz, Nissan Senior Vice President of Sales and Marketing in the US, said to Automotive News. The big changes reportedly include a thorough restyling and some new tech. Nissan North America Director of Product Communications Dan Bedore confirmed to Autoblog the company will launch refreshes to the Sentra and Altima "later this year" but wouldn't give a more precise timeline or other details about them. However, rumors about the restyling are already out there, and Sentra's overhaul reportedly takes inspiration from the Pulsar in Europe. That might mean a move to Nissan's pointed, V-shaped grille and more aggressive, angular headlights with better-integrated LED running lights than the current design. Meanwhile, the Altima's update potentially borrows cues from the Murano and Maxima and could see improved fuel economy. This comprehensive restyling comes despite Nissan already having a major success in the US with the current Sentra. Volume this year is up 15.5 percent through May with 88,701 sales. Also, the sedan had its best numbers in the past 25 years in 2014 with 183,268 of them sold, according to Automotive News. Related Video:

2018 Jeep Grand Cherokee vs. midsize crossovers and SUVs: How they compare on paper

In a world full of SUVs and crossovers all competing for similar buyers in similar segments, there are still some models that find their own little niches that lack such fevered fighting. The Jeep Grand Cherokee is one of those vehicles. It's an oddball in the sense that it's a midsize crossover SUV with a unibody chassis and independent suspension, but it still uses rear-wheel-drive and four-wheel-drive systems and has some off-road capability. It's also a midsize crossover, but only offers two rows of seats. Despite the Grand Cherokee's odd nature, we did come up with a few crossovers and a classic SUV that seem to match the Jeep in size and pricing. We looked at the numbers to compare them on paper. You can find the raw data in the chart below and deeper analysis after that. As always, this is just a comparison of specifications and you'll want to check out our driving impressions of each car if you're getting serious about one or all of these vehicles. And if you want to compare any of these against other vehicles, be sure to check out our comparison tool. Engines and Drivetrains When comparing base engines, the Jeep Grand Cherokee's 295-horsepower is the clear power winner, beating the next most powerful 4Runner by 25. But in torque, the 4Runner takes the laurels with 278 pound-feet, narrowly edging out the Edge's (no pun intended) turbocharged 2.0-liter four-cylinder's 275. That four-cylinder in the Edge will also be picking up another 5 horsepower for 2019, but it still won't win this power contest. Both Ford and Jeep also have another advantage in the fact that you don't have to settle for the base powertrain. Ford has two other engine options, a naturally aspirated V6 and a twin-turbocharged V6, the latter of which outguns the Grand Cherokee's gasoline V6 in both power and torque. That engine will also be bumped up to an impressive 335 horsepower and 385 pound-feet of torque. View 20 Photos The Jeep has the most engine options, though, and it's the only to offer V8 and diesel options. On most Grand Cherokees, the options include a 5.7-liter V8, which is only available with 4WD. It makes 360 horsepower and 390 pound-feet of torque, outperforming even the 2019 Edge's twin-turbo V6. The diesel engine doesn't make much power with just 240, but it makes up for it with torque at 420 pound-feet. And of course there are the SRT and SRT Trackhawk models with even bigger and supercharged V8 engines respectively.
