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.

SUV lifts you up where you belong and leapfrogs traffic jams

So, you're at a dead stop, stuck in traffic, when it pulls up behind you. It appears to be a garden-variety Jeep Grand Cherokee. That is, until its undercarriage lifts the Jeep 9 feet into the air, and the whole rig straddles you and the cars ahead of you in a bid for open road. The car is called the Hum Rider, and no, you can't buy one at the Jeep store. It's a one-off publicity stunt intended to promote Verizon Telematic's Hum platform, which plugs into a car's OBD port and for $10 a month provides vehicle diagnostics, roadside assistance, location tracking, and speed and geo-fencing alerts. (Not sure if Hum tracks vertical leaps.) Verizon enlisted viral marketing agency Thinkmodo to promote the Hum, and this idea was head and shoulders above the rest. "We saw this one [and said], 'Wow, that is crazy,' said Jay Jaffin, Verizon's VP of marketing. "We loved the idea." Thinkmodo co-founder James Percelay told Mashable that they wanted to represent the upgrade Hum brings to cars. So the car goes up. Get it? Here's the star of this story: Hum Rider's designer, Scott Beverly, has done visual effects for Hollywood in The Dark Knight, Inception and Interstellar. He works for A2Zf, a Lancaster, Calif., design and engineering firm that keeps the world filled with Batmobiles, Red Bull Can Cars and beautifully designed VWs and Audis. A2Zf has also worked with NASA on X-planes and with Northrup on the B2 bomber, so compared to those projects, a car-straddling car is hardly a stretch. So what does it take to make a car do this? How about: Over 300 feet of hydraulic lines that operate everything - the lift mechanism, steering, braking and power to the drivetrain. A gas-powered Honda generator under the hood that powers hydraulic pumps pushing out 900 pounds of pressure. A lot of mechanical structure. Hum Rider weighs 8,500 pounds, almost double a standard Grand Cherokee. Heavy-duty truck tires to support all that weight. Four undercarriage cameras that allow the driver to see and clear what's beneath him. What did it cost? They're not saying. What would it be worth, the next time you're stuck in traffic? Priceless.
