Third Report: Long-Term 2017 Jeep Grand Cherokee Trailhawk

Long-Term Report

Christian HazelPhotographer, Writer

With the word “Trailhawk” in the name of your vehicle, expectations for off-road performance are high. And given the nature of what we do on a daily basis, you’d think we were bumping down desert washes and mountain trails in various states of disrepair every single day. Unfortunately, the past 5,000 miles of testing our 2017 SUV of the Year winner have been slightly less exciting than that with our daily trail often encompassing 50-80 miles of pavement with only the occasional weekend off-road foray. So, in this installment the reality is we’ve been using our Jeep Cherokee Trailhawk in pretty much the same manner as 99 percent of the people who might purchase this vehicle: mundane daily commuting, running errands, and a smattering of unpaved trails. So let’s dive in.

For starters, the Cherokee Trailhawk pulls in an audience more often than you’d think. Whether inquiries at the gas pump or simply a thumbs-up at a stoplight, people notice the fact that, at least on the surface, the Trailhawk is a bit more than your average Grand Cherokee. Compliments like “that’s a seriously cool vehicle” and “nice Jeep” come at least once a week. And then there’s the occasional forum lurker who hasn’t seen a new Trailhawk in person yet and wants to peek inside to inspect every button, crawl underneath for a skidplate evaluation, and grill us about its performance in varying types of terrain. In short, some people get genuinely excited about seeing one of these Jeeps. And for some, getting noticed is what matters. Not us, though. We’re more about performance than notoriety.

So, on to performance. For starters, the mileage delivered from the 5.7L Hemi and eight-speed transmission has been anything but unacceptable. We’ve begun leaving the “Eco” mode off more frequently or going full-bore and selecting “Sport” mode. And even then, our average mileage as compared with last installment, in which we operated almost solely in Eco mode, dropped less than a 1/2 mpg, with a combined mpg this period of 15.34. Our highway-only jaunts routinely see numbers north of 18 mpg, and that’s at crazy California freeway speeds of 80 mph. In Sport mode at any speed, there’s plenty of horsepower on tap to pass, jump out in traffic, or just get your acceleration fix for the day. The downside is that the suspension is still somewhat mushy in Sport mode. Ideally the chassis dynamics would “sportify” up with the same degree as the engine and transmission when you depress that little button, but if all Sport mode delivers is tons of power, razor-sharp throttle response, and perfect transmission shifts, then we’ll take what we can get. Mechanically the Trailhawk has been flawless this review period, with no glitches, quirks, or maintenance required. Just add fuel and go.

Our off-roading this portion consisted of mostly scenic fire roads comprised of hard-packed dirt with some undulations, ruts, and moderate obstacles. At higher speeds on dirt roads we enjoy the Trailhawk’s suspension. It’s soft without being floaty. All but the hardest hits are absorbed nicely, and the vehicle tracks true and stable without getting squirrely. The 265/60R18 Goodyear Wranglers don’t feature the world’s most aggressive tread pattern, but on the Trailhawk they do strike a nice balance between low-noise on-road civility and biting off-road capability. While subjective, we really like the Trailhawk-only open five-spoke wheel design with red flatfender silhouette that pays homage to Jeep’s past. But also the fact that they’re an 18-inch and not 20- or 22-inch diameter leaves a lot of sidewall meat on the proverbial bone to help cushion off-road shock and allow for decent ground clearance if you ever air down for off-road use. We’ve been leaving the tires at their 33 psi street pressure, and even with that much in ’em the Trailhawk has clawed and maneuvered to the top of every scenic outlook we’ve pointed it at off-road. Next time we’ll up the ante with some more serious off-road work that could put the Trailhawk-specific open towhooks to use.
