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.

How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.

2018 Jeep Wrangler Rubicon Alaska Cannonball | 14,000 miles to Deadhorse and back

I've never delayed big adventure long enough to fill a bucket. But I do have a bucket item that dates to 1992: drive from Deadhorse, Alaska, to Tierra del Fuego, Argentina. Twenty-six years later, it's time. But first, I needed a vehicle. And a Jeep Wrangler was not my first choice. Growing up as a kid in the Midwest, I loved Jeeps. But around 10 years ago I went on a camping trip to Death Valley with a colleague, testing the early JK Wrangler against the competition. By the end of it, I couldn't justify the ergonomic and physical punishment for the admittedly massive capability. So two years ago, I bought a 1994 Toyota Land Cruiser project truck to make the journey. I paid too much, and the Cruiser revealed itself to be not a garage project, but the Manhattan Project. I took this as a good omen. Adventure begins in the deep end, so why wait to get there? During a break from discovering enough gremlins to reboot the movie franchise, I had dinner with Jeep's West Coast PR guy. I mentioned my plans for a six-month overlanding trek to Alaska. He said, "You know, we've got a new Wrangler coming out — that might be a good test of the chassis." My outside voice said, "That would be interesting." My inside voice said, "Hmmm." Anything's possible after 10 years, right? I might like it. Might. Many plans have gone awry on the way to this moment. It's taken more than a year to lock in a start date, because Jeep couldn't spare a Wrangler Rubicon. Everyone else in America keeps buying them. A suitable Wrangler was found eventually, but now the deed had to be done in three months, not six. What was going to be a comfortably-paced, backwoods roll up to Alaska and back has turned into the Rubicon Overland Cannonball. I know 14 weeks is plenty of time to drive to the Arctic and back. (Tierra del Fuego is officially off the itinerary.) However, the point of this trip is to fit in as much dirt, as many bucket-list trails, and all the wild America possible. That means my route's about 14,000 convoluted miles of criss-crossing the country in all the cardinal directions. And that's assuming everything goes to plan. Until last week, I was doing this trip with a friend from college who lives in Marietta, Georgia. He was the photo/video guy. Then he had a medical emergency, so the only trip he's taking is to the OR and rehab. Now I'm going by myself, and I think it's important to point out that I have no idea what I'm doing. That isn't modesty, that's truth: zero clue.
