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.

Chrysler highlights Mopar lineup for SEMA

SEMA is all about aftermarket parts, and in Auburn Hills that all comes down to one name: Mopar. After having previewed its lineup for this year's Vegas tuner expo earlier this month, Chrysler has now revealed what may not quite be its full dossier of modified show cars, but a good portion of them.
All told Mopar is preparing 20 vehicles for display at SEMA this year. Among them you'll find the Ram Sun Chaser, a 1500 Quad Cab show truck kitted out in two-tone orange and black paint, a roof rack for surfboards, onboard shower and convertible tailgate. The white Fiat 500L is called the Adventurer and is modified for a more rugged look that could hint at the upcoming crossover version. The Jeep Cherokee Trail Carver upgrades on the Trailhawk package with everything from roof basket to rock rails. To counterbalance the off-roaders, there's also a modified Chrysler 300S with a deep black paint job, special grille, Varvatos-edition wheels and more.
All four concepts details so far have Katzkin interiors as well, and there's also an unspecified Dodge Durango with a storm-trooper look in the gallery above. But for more details on what Mopar has installed on the Ram, 500L, Cherokee and 300, you'll want to delve into the press release below.

Chrysler 3.0L EcoDiesel V6: Autoblog Technology of the Year finalist

Offering a diesel engine in an American pickup is anything but new - Ford, General Motors and Chrysler all offer excellent and almost impossibly powerful oil-burning engines in their various fullsize trucks. What is new and novel about the 3.0L EcoDiesel, though, is its size, and the variety of vehicles that use it. It's the smallest engine, as far as displacement is concerned, currently offered in a large truck in the US, and, for 2014 and 2015, it is available in the Ram 1500 and the Jeep Grand Cherokee.
Though it may be small, it's got muscle. While 240 horsepower isn't particularly impressive these days, the engine's 420 pound-feet of torque more than makes up for that. The torque rating is even greater force than even the big 5.7-liter Hemi can muster. Chrysler's well-regarded eight-speed automatic transmission makes the most of all that bull-headed pulling power in both the Ram and Grand Cherokee. Chrysler claims the Ram EcoDiesel 1500 can tow as much as 9,200 pounds when properly equipped, which makes it "90-percent of the Hemi with a night and day difference in fuel economy."
Make no mistake; it's that promise of a sizable fuel economy improvement that many long-haul truckers will be most interested in. In the Ram 1500 that we tested for our Tech of the Year competition, the diesel engine costs $2,850 more than the gas-fed V8, and Ram estimates that EcoDiesel buyers will pay off their investment when compared to the Hemi engine in less than three years, which is considerably less time than the 4.5 or so years the average buyer will keep his or her fullsize pickup. The more you drive, the more you'll save, and the math proves equally as effective in the Jeep Grand Cherokee.
