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.

FCA UConnect fiasco could set over-the-air updates back years

Since cars have become more software dependent, most major automakers have been inching toward enabling over-the-air updates to keep vehicle electronics, ranging from infotainment systems to safety features, current. But there are only two car companies — Fiat Chrysler and Ford —± currently doing OTA updates, and on a limited basis. GM CEO Mary Barra announced last summer that the automaker will launch a new EV architecture and infotainment system capable of over-the-air updates "before 2020." The one exception, per usual, is Tesla. Since the release of the Model S almost six years ago, the maverick EV automaker has made routine OTA software updates a core part of its vehicle platforms and value proposition, and has sent out updates for everything from adjusting ride height to enabling Autopilot, largely without incident. When I've asked automakers why they can't do the same thing, I've heard reasons ranging from running afoul of their dealers (and archiac regulation) to security concerns. Automakers like Ford and General Motors say they want to act like tech companies, which routinely send out OTA updates for a wide range of devices, but overall the car industry still moves at a very cautious snail's pace. And when automakers do try to move faster and take more risks — unlike with a smartphone update, which people bitch about but live with — the consequences can be significant when things go wrong. That's the case with Fiat Chrysler America and its recent public-relations nightmare when an OTA update went awry. The update went out at the end of last week for the Uconnect system in late-model vehicles, and it made head units go into a near continuous reboot, which caused owners to not only lose access to entertainment features, but also critical functions like emergency assistance. Almost immediately, owners took to Twitter to express outrage, and FCA was caught flatfooted. A tweet went out on Monday on the UconnectCares Twitter account that read, "Certain 2017 & 2018 Uconnect systems may experience a reboot every 45-60 seconds. Our Engineering teams are investigating the cause and working towards a resolution.

Watch this 840-hp Jeep Grand Cherokee SRT8 walk away from GT-Rs and M3s

This last-generation Jeep Grand Cherokee SRT8 does things that SUVs just shouldn't be able to do, like win drag races against tuned Nissan GT-R and BMW M3 coupes. Granted, the owner isn't coming into this fight with a stock Jeep – far from it. In addition to twin turbos whistling away, he says the engine is a 449-cubic-inch V8, which is nearly 7.4 liters of displacement. As it runs here, the driver claims that the turbos are pumping out around 14 psi of boost to give an estimated 840 horsepower. What's more, he further maintains the powertrain could reach around 1,200 hp with things fully cranked up. Even somewhat dialed back, this Jeep is ready to take on a breadth of formidable challengers, including a couple of Chevrolet Corvette models and a Lamborghini Aventador. Check out the video to see how this menacing Grand Cherokee fares in a day at the races.
