Off-roading the Lyman Trail in the 2017 Jeep Grand Cherokee Trailhawk

Lyman Trail is in the backwoods of the Chelsea Proving Grounds in Chelsea, Mich. It's where FCA goes to push off-roaders to the limits. Autoblog's Greg Miglore made a recent visit to Lyman Trail with the 2017 Jeep Grand Cherokee Trailhawk. Check out the video to see how the SUV performed. Show full video transcript text [00:00:00] We are on Lyman Trail here, deep within the Chelsea proving grounds in the woods. This is where they test all the off-roaders, the Jeeps, the Rams, everything that's capable and needs some sort of a trail rating - this is where they bring it to shake it down. It's all downhill from here. Except when it's rocky and wet. Here we go! [00:00:30] Grand Cherokee Trailhawk is very capable off-road. Of course it's trail-rated. It definitely has all of the gizmos and things that you need to get over the obstacles that we're going to encounter. This first one is called traction. This is where, basically, to be trail-rated the vehicles need to have a certain degree of traction so they can basically, you know, stay sure-footed over certain obstacles. When going up things like this, pick your line, I'm going straight up the middle, and just stay nice and even. [00:10:00] Go straight up let the Jeep do the work, keep on going, skid plates doing their thing, there ya go. This one is over the riverbed. This simulates a dried riverbed. It's rocky, lots of stones here, things you might see on the shores of Lake Michigan. We're just gonna go right over it. Keep it nice and simple. Nice and easy. Okay, hit it kind of hard, gonna straighten the wheels. Again, you hear those skid plates, they are protecting the fuel tank, ... [00:01:30] the transfer case, and the front of the vehicle. So I'm not gonna touch the brakes, I just want to go over it nice and easy. We've come upon one of my favorite events here. This is where you go through the water. It's basically mud, a little bit of a bog kind of thing. Jeeps are so capable, you don't even have to worry about it.The trick about going through the water is to keep a nice even pace ... [00:02:00] and don't loose your nerve. Some people go in the water and are like "woah," freaking out because literally there's water all around you. So, just keep right on going, steer, point the vehicle right on through. We're making some waves here. Keep on going. Keep it smooth. Up the hill we go. And there you have it. Your Jeep not only went off-roading, it went off-landing. That's a bad joke.

Feds fretting over remote hack of Jeep Cherokee

A cyber-security gap that allowed for the remote hacking of a Jeep Cherokee has federal officials concerned. An associate administrator with the National Highway Traffic Safety Administration said Thursday that news of the breach conducted by researchers Chris Valasek and Charlie Miller had "floated around the entire federal government." "The Homeland Security folks sent out broadcasts that, 'Here's an issue that needs to be addressed,'" said Nathaniel Beuse, an associate administrator with the National Highway Traffic Safety Administration. Valasek and Miller commandeered remote control of the Cherokee through a security flaw in the cellular connection to the car's Uconnect infotainment system. From his Pittsburgh home, Valasek manipulated critical safety inputs, such as transmission function, on Miller's Jeep as he drove along a highway near St. Louis, MO. The scope of the remote breach is believed to be the first of its kind. The prominent cyber-security researchers needed no prior access to the vehicle to perform the hack, and the scope of the remote breach is believed to be the first of its kind. A NHTSA spokesperson said the agency's cyber-security staff members are "putting their expertise to work assessing this threat and the response, and we will take action if we determine it's necessary to protect safety." A Homeland Security spokesperson referred questions about the hack to Chrysler. Fiat Chrysler Automobiles has already been the subject of a federal hearing this month, in which officials scrutinized whether the company had adequately fixed recalled vehicles and repeatedly failed to notify the government about defects. But cyber-security concerns are a new and different species for the regulatory agency. Only hours before the Jeep hack was announced by Wired magazine earlier this week, NHTSA administrator Dr. Mark Rosekind said hacking vulnerabilities were a threat to privacy, safety, and the public's trust with new connected and autonomous technologies that allow vehicles to communicate. NHTSA outlined its response to the cyber-security challenges facing the industry in a report issued Tuesday. In it, the agency summarized its best practices for thwarting attacks and said it will analyze possible real-time infiltration responses. But the agency's ability to handle hackers may only go so far.
