2018 Jeep Grand Cherokee Trackhawk First Drive | Crazy. Good.

TAMWORTH, New Hampshire – We're tempted to tell you that the 2018 Jeep Grand Cherokee Trackhawk is ridiculous. It's borderline frightening to think that we now live in a world where anybody with the money and the gumption can stroll into the nearest Jeep dealership and place an order for a 707-horsepower Hemi-powered Grand Cherokee. Let's put this slice of history into perspective. The original Jeep, the one used by the military, boasted 60 horsepower from the Go Devil four-cylinder engine under the hood. The most powerful version of the muscle car-era 426-cubic-inch Hemi was factory-rated at 425 hp. And even if that legendary powerplant was underrated from the factory, the Grand Cherokee Trackhawk still obliterates it by a couple hundred horses. In an SUV. Seven-hundred-horsepower sport utility vehicle doesn't exactly roll off the tongue, does it? And conventional wisdom says it shouldn't. But we're here to tell you otherwise. After driving the Trackhawk in and around the streets of Portland, Maine, and taking it to Club Motorsports in New Hampshire, we're convinced that Jeep and SRT engineers have managed to defy physics and reason. The Trackhawk isn't just fast, it's also manageable. Subdued, even – at least when you want it to be. Put the hammer down, summon the nearly demonic power of supercharged combustion, and all hell breaks loose. But the tires don't. With launch control engaged and with the programmable engine speed properly chosen, the all-wheel-drive Trackhawk rockets to 60 miles per hour in just 3.5 seconds, over and over and over again. No drama, no wheelspin, just g-force, pressing you and four close friends into the backs of your seats. It's addictive, and the only penalty is single-digit fuel mileage. But we'll wager a guess that anyone shopping for a Trackhawk isn't much concerned about its drinking problem. The only proper way to experience the Trackhawk's acceleration is from inside. But, to give you an idea of its speed and power, check out the videos below. Stick around for a walkaround both inside and out, and for a look under the hood. Jeep had to make a few small changes to the well-known 6.2-liter supercharged Hellcat V8 engine to shoehorn it under the hood of a Grand Cherokee. The oil pan is reshaped and baffled, the intercooler is modified, and the exhaust manifolds are new. The result is a reduction in torque from 650 pound-feet in Dodge Hellcat models to 645 in the Jeep, but we wouldn't worry about that.

Hellcat motor 'fits like a glove' in the Wrangler and Gladiator, says Jeep

Just like "technically correct" is the best kind of correct, "technically possible" is the best kind of possible. Specifically, it's technically possible to slot a Hellcat crate motor into the Jeep Wrangler and Gladiator, as confirmed by Jeep brand chief Tim Kuniskis. Speaking to Australian media last week, Kuniskis went on to say that "everybody" keeps asking him if the supercharged, 6.2-liter Hellcat V8 fits in the Wrangler and Gladiator, and that the answer is yes. "It fits like a glove," said Kuniskis. But — there is a but — the fitment is so close for comfort, it makes the combination one that Jeep can never produce. "There's no air space around the engine [...] so you have no crush space, you have nothing that can be used to absorb energy in a crash. It's not a problem to put it in — other than emissions and fuel economy — except it would never pass any crash tests, and that's a problem," as Kuniskis told Drive. However, since the Hellcat is now out of the bag, it's probably only a matter of time until hobbyists with access to these engines will start putting them into Wranglers and Gladiators. And with the time-honored piece of advice — just don't crash into anything — it'd be a combination worth seeing and hearing. Just to throw it out there, a "Hellcrate" engine costs less than $20,000 new. Kuniskis also said that Jeep is "gauging interest" for the J6 concept, one of the Easter Jeep Safari concepts that were just revealed. "[The J6] is just a concept at this stage. But that doesn't mean we're not going to gauge interest for it." However, he said justifying its production is apparently "tough."

Tour the Jeep Wagoneer Icon Reformer with its creator Jonathan Ward

Icon has released a plethora of amazing machines, and has more coming down the pike. One of the company's latest creations is a Jeep Wagoneer that was done as part of Icon's Reformer line, which Jonathan Ward, the head of Icon, explains is a thorough restoration and upgrade, but with a fresh restored finish. This is in contrast to the company's Derelict series that keeps the rough exterior while upgrading everything underneath. And the level of detail in the Reformer Wagoneer is amazing, as shown by this video from The Hoonigans in which Ward gives a tour of the SUV. Starting on the outside, the truck is pretty close to stock in appearance, though the color and faux wood trim were never offered on it. Badges are a mix of originals, and a few tweaked ones for use on this Jeep. For instance, the front fender badges now feature the engine displacement of the Chevy LS V8 under the hood. Also, the round Jeep badges front and rear now have the Icon lizard badge. Inside, custom upholstery was added featuring patio furniture fabric for durability and the nifty pattern. Anything that would have been plastic, such as some of the chrome trim and the gauge cluster fascia, or vinyl, such as the door panels, have been upgraded to genuine metal or leather components. Icon even re-created a casting for the steering wheel to replace the old one. As already mentioned, this Jeep Wagoneer has a Chevy LS V8 displacing 6.2 liters. It naturally connects to a four-wheel-drive system with a Dana 60-size rear axle and 44-size front axle. The chassis was built by Art Morrison, a company known for its custom vintage car chassis. The suspension consists of coilover shocks and springs from Fox Racing and Eibach respectively. This is all just a brief overview. Check out the whole video above for all the neat details.
