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's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

April Fools' Day brings Jeep Sedan, Hyundai N Roadster, Toyota Yaris pickup and more

There is one day out of the year when public relations professionals have permission to lie to journalists and to the public: April Fools' Day. Manufacturers release details about wild, weird and wacky new technology, concept vehicles and services. Some take it to obvious outlandish extremes (Jeep Sedan anybody?), while others plot to mislead with products that are just outside the realm of possibility. Check out all the "jokes" below. BMW Motorrad BMW doesn't want to exclude anybody from experiencing the thrill of high-level racing, so it is introducing 'iRace" autonomous programming on its S 1000 RR sport bike. It includes beginner, sportsman, advanced and unlimited driving modes, and stores GPS information for all Superbike world championship tracks. Hyundai Hyundai is wrong for this. The Hyundai N Roadster is the work of South Korean designer Yeonjoon Park and features a 2.0-liter turbocharged engine, rear-wheel drive and a hard convertible top. Hyundai says this is a "concept (for now)," but we think it'd make a seriously great Mazda Miata competitor. Honda Honda wins the award for the best interactive gimmick, as its press release for the '90s-inspired special-edition Pastport includes a live hotline number with a message from Fred Savage. Call 1-833-PASTPORT for more information. Jeep Put the Jeep Cherokee face on the Chrysler 300's body, and voila! The 2019 Jeep Sedan is born. We can't decide if the name or the rendering is better. Land Rover Accessibility to charging ports is of major concern to anybody with a plug-in vehicle. So, with the recent launch of the Range Rover P400e and Range Rover Sport P400e, Land Rover is putting forth an effort to install more stations around the globe. First up is Scotland's Isle of Skye. Adventurers need juice too! Lexus Australia Lexus expands its Encore service to include doggos. The new service, called Enpaw, will take pups to luxury boarding kennels in style. Toyota U.S. Toyota created the Yaris Adventure pickup for "those who want to tell their friends they own a truck but never veer off pavement." It's part Mazda 2, part RAV4, 100 percent ute and it looks ... great? Creating a new segment might be all fun and games to Toyota, but Ford is reportedly considering a Focus-based ute in a similar, albeit larger, style. Toyota Australia Toyota is launching a new HiAce van, and it's already getting a limited-edition variant called the PieAce.
