2018 Jeep Grand Cherokee Trackhawk Drivers' Notes | Haulin' the groceries

Powered by the same supercharged Hemi at the heart of Dodge's Hellcat cars, the 2018 Jeep Grand Cherokee Trackhawk is the sort of vehicle that comes from a " Why not?" attitude from the maniacs at SRT. It's not for the faint of heart, nor for the cash-strapped. With 707 horsepower and 645 pound-feet of torque, it's capable of a 0-60 sprint of just 3.5 seconds. Its base price, however, is $86,995, though our tester's sticker totaled just a few bucks shy of $100,000. Senior Editor, Green, John Beltz Snyder: "What business does a Jeep have going 0-60 in 3.5 seconds?" This was my thought as I merged into rainy rush-hour traffic on Woodward Avenue in the 2018 Jeep Grand Cherokee Trackhawk. "Why does an SUV need to have 'Track' in the name?" I thought as I unintentionally broke the tires loose pulling away from a stoplight. I hit the "Eco" button, but the Jeep still roared with every toe-tap, and still managed to gulp down nearly a quarter of a tank of gas on my ride home. That sound, though, is amazing, and surely more unsettling to other drivers coming from such a big beast of a ute. Anyway, this Jeep feels more grown-up than other Hemi-powered vehicles I've driven. The fit and finish in this $99,000 Jeep is far nicer than, say, the Dodge Durango SRT (though at a much higher cost). If another driver didn't pay close attention to the badging, they might see this and think it just another Jeep. The sound, though, will give it away every time. Associate Editor Joel Stocksdale: If Fiat-Chrysler knows how to do anything, it's making fast SUVs, and the Grand Cherokee Trackhawk is further proof of that. And by that I mean, they know how to make them fast, and they know how to make them pleasant to drive. The Trackhawk definitely handles the fast part better than its SRT Durango and SRT Grand Cherokee cousins, what with its extra 230-odd horsepower. This big beast seriously rockets when you punch the throttle. The nose rises up, the supercharger screams, the exhaust rumbles and the speedometer ticks up much faster than you'd ever think. And it feels strong at all revs. Also impressive is that you don't have to really think when flooring it. The all-wheel-drive and fat tires offer so much grip the Jeep simply goes. The pleasant to drive part comes in the fact that the Trackhawk is very comfortable. The suspension has plenty of give, providing a good ride over pockmarked Motown roads.

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.

Next-generation Jeep Wrangler arriving at the end of 2017, diesel for 2019 model year

The folks at JL Wrangler Forums have come across some very juicy information regarding the next-generation Wrangler, thanks to an anonymous source who got the details from a dealer meeting. Among the information provided by the source is the timeline for the new Jeep's release. It will be fully revealed at this year's Los Angeles Auto Show, and it will hit dealers this December. At launch, the next-gen Wrangler will be available with both a 3.6-liter V6 with either a manual or automatic, and a 2.0-liter four-cylinder that can only be had with an automatic. We expect this engine to be turbocharged and pack as much as 300 horsepower. It also seems Chrysler is still making good on its promise of a diesel Wrangler for this generation. Photos taken by a JL Wrangler Forums user show what looks like a diesel exhaust fluid tank underneath one of the prototypes seen above. There could be a bit of a wait on that powertrain, though. According to the JL Wrangler Forums source, it won't be arriving until near the end of the 2019 model year, so potentially at the end of the 2018 calendar year, and possibly early 2019. The other big news is that the anonymous source confirmed that there will in fact be a hardtop with a power sliding opening. The feature was rumored years ago, and we may have had our first look at it thanks to earlier spy shots also taken by a JL Wrangler Forums member. The photos showed a mysterious set of switches on the windshield header that may have been controls for the power top. This feature won't be available at launch according to the anonymous source, and will instead debut near the end of the 2018 model year, so likely early- to mid-calendar year 2018. Some other minor changes to colors and equipment were revealed also, and can be seen at the forum website, here. Related Video:
