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.

Feds fretting over remote hack of Jeep Cherokee

A cyber-security gap that allowed for the remote hacking of a Jeep Cherokee has federal officials concerned. An associate administrator with the National Highway Traffic Safety Administration said Thursday that news of the breach conducted by researchers Chris Valasek and Charlie Miller had "floated around the entire federal government." "The Homeland Security folks sent out broadcasts that, 'Here's an issue that needs to be addressed,'" said Nathaniel Beuse, an associate administrator with the National Highway Traffic Safety Administration. Valasek and Miller commandeered remote control of the Cherokee through a security flaw in the cellular connection to the car's Uconnect infotainment system. From his Pittsburgh home, Valasek manipulated critical safety inputs, such as transmission function, on Miller's Jeep as he drove along a highway near St. Louis, MO. The scope of the remote breach is believed to be the first of its kind. The prominent cyber-security researchers needed no prior access to the vehicle to perform the hack, and the scope of the remote breach is believed to be the first of its kind. A NHTSA spokesperson said the agency's cyber-security staff members are "putting their expertise to work assessing this threat and the response, and we will take action if we determine it's necessary to protect safety." A Homeland Security spokesperson referred questions about the hack to Chrysler. Fiat Chrysler Automobiles has already been the subject of a federal hearing this month, in which officials scrutinized whether the company had adequately fixed recalled vehicles and repeatedly failed to notify the government about defects. But cyber-security concerns are a new and different species for the regulatory agency. Only hours before the Jeep hack was announced by Wired magazine earlier this week, NHTSA administrator Dr. Mark Rosekind said hacking vulnerabilities were a threat to privacy, safety, and the public's trust with new connected and autonomous technologies that allow vehicles to communicate. NHTSA outlined its response to the cyber-security challenges facing the industry in a report issued Tuesday. In it, the agency summarized its best practices for thwarting attacks and said it will analyze possible real-time infiltration responses. But the agency's ability to handle hackers may only go so far.

5 classic trucks and their polarizing modern revivals

EVs are helping eliminate Detroit's gas-guzzling problem. Some revivals of gas-powered classics are getting the EV treatment.  But not every revived model looks exactly like its original counterpart. We're in a new era of hulking Detroit metal, and you can thank EVs. Americans can't get enough of their big, beefy trucks and SUVs. But for many years, some of the biggest gas guzzlers fell out of fashion as gas prices rose and emissions regulations tightened. But in the past few years, some of the most iconic American truck nameplates have been brought back to life with electric motors, like the GMC Hummer. In other cases, as with the Ford Bronco, improvements in engine technology and more interest in rugged adventure vehicles made a gas-powered revival possible. Even some revivals that started as gas-powered, like the Chevy Blazer and the Jeep Wagoneer, are now getting electrified spinoffs. (Even if they don't always look quite as sleek as their original inspiration.) Here are side-by-sides of five classic American trucks and their modern counterparts. The Jeep Wagoneer 1975 Jeep Wagoneer and 2024 Electric Jeep Wagoneer SStellantis After a long wait, Jeep released its revival of the classic Wagoneer and Grand Wagoneer in 2020. Starting later this year, an electric version of the luxury Jeep SUV will join the Wagoneer lineup. The Chevrolet Blazer A 1973 Chevrolet Blazer and a 2024 Chevrolet Blazer EVGetty Images, General Motors The Chevrolet Blazer was first rebooted in 2019 as a sporty family SUV. The modern Blazer shares zero resemblance to its boxy, off-roading older sibling, but it has still managed to become one of Chevy's more popular SUVs in recent years. The Blazer EV came later, and was one of the first models GM built on its new Ultium battery platform. The Hummer A Hummer H2 and the 2023 Hummer EV pickup truckGetty Images, General Motors Once the poster child for Detroit's big, bad gas guzzlers, the Hummer got new life as an electric pickup truck in 2021. The Ford Bronco A 1971 Ford Bronco and a 2022 Ford BroncoFord Motor Co. After a rouge group of engineers and designers inside Ford spent years trying to breathe life back into the Blue Oval's boxy off-roader, the Ford Bronco was finally resurrected in 2020 amid a rise in popularity for rugged adventure vehicles.
