New autonomous testing ground in Michigan will help battle bad weather

If one of the big weaknesses of autonomous vehicles is their ability to navigate in the snow, consider this a trial by fire. The American Center for Mobility says it has opened its $110 million driverless car testing facility on the site of a former General Motors assembly plant in Michigan, with Toyota and auto supplier Visteon the first to begin testing this week. The ACM proving ground is a 500-acre site at historic Willow Run in Ypsilanti Township, near Ann Arbor. It's one of 10 sites designated by the U.S. Department of Transportation as pilot proving ground sites to test AV technologies. It features a variety of simulated environments to test driverless cars, including a 2.5-mile highway loop, two double overpasses, intersections, roundabouts and a 700-foot curved tunnel. It also opens just as the region experiences a series of snowstorms and the first frigid temperatures of the season. That ability to test autonomous vehicles in a wide variety of weather conditions is important, as autonomous vehicle sensors have struggled to handle cold, wet and snowy conditions. Google parent Alphabet in October said its Waymo division was expanding its winter testing operations to Michigan, making it the sixth state where it's testing its driverless car systems. In a Medium blog post, Waymo CEO John Krafcik wrote that "This type of testing will give us the opportunity to assess the way our sensors perform in wet, cold conditions. And it will also build on the advanced driving skills we've developed over the last eight years by teaching our cars how to handle things like skidding on icy, unplowed roads." Waymo also opened a development center in suburban Detroit in 2016, working with Fiat Chrysler to integrate its autonomous technology into Chrysler Pacifica hybrid minivans. Visteon began testing and validating its DriveCore autonomous driving platform to evaluate algorithms, vehicle-to-vehicle and vehicle-to-infrastructure technology and other systems. Toyota used the facility Wednesday to begin orientation and driver training. ACM has so far secured $110 million to construct the first two phases from founders Ford, Hyundai America Technical Center, Toyota and Visteon, and says it expects to announce more investment soon.

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.

Toyota recalls 337,000 RAV4s and HS250h models for tie rod failure

UPDATE: The post has been updated with additional information from NHTSA. The Basics: Toyota is recalling 337,000 2006-2011 model year Toyota RAV4 crossovers built between October 31, 2005 and September 7, 2010 as well as 2010 model year Lexus HS250h cars built between July 6, 2009 and August 26, 2010. The Problem: When either an affected RAV4 or HS250h is given an alignment and the tie rod adjustment nut on the rear control arm isn't tightened properly, the threads on the tie rod can start to rust. If this happens, the nut may break off and throw off the alignment drastically and suddenly. This isn't a case of the car simply pulling to one side, either. This would seriously upset the balance of the car and could cause the driver to lose control and crash. This is also the third time these vehicles have been recalled for the same issue. Injuries/Deaths: It's unknown if this control arm issue has resulted in any injuries or deaths. Autoblog reached out to Toyota for more information, but a company representative told us that the company isn't able to discuss injuries or deaths caused by this issue (if any) at this time. Based on information from NHTSA documents, it does not appear that any crashes, injuries or deaths have been attributed to the defect addressed in the current recall. The Fix: The dealer will completely replace the rear suspension assemblies at no cost to the owner. The tie rods and nuts will also be coated in epoxy to prevent future rusting from occurring. According to Car and Driver, the previous recalls involved tightening nuts, coating decent tie rods in epoxy and completely replacing rusted ones. The car magazine reports that further complaints were filed and the company is now replacing all components regardless of condition. If you own one: Toyota will notify owners of affected cars by mail. Owners can also check whether their cars are affected by entering the VIN at safercar.gov/vin. Owners with questions can also reach Toyota customer service at 1-800-331-4331 or Lexus customer service at 1-800-255-3987.
