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.

Jeep Renegade refresh spied with big infotainment screen

Based on these recent spy shots, it looks like the littlest Jeep is getting a little makeover soon. They show a Renegade with camouflage on the front and rear, indicating there will be some changes to the outside. Whatever those changes are, they're extremely subtle. The headlights and taillights look untouched. The grille may have slightly wider slots than the current one, and the available fog lights look a little bigger. The biggest change appears to be inside. Sitting in the center stack is a massive touchscreen. It's bigger than any available on the current Renegade. It also pushes physical buttons and knobs for controls lower down in the stack, instead of surrounding the screen. The lower part of the center stack has also been redesigned for this new button layout, which includes driver assist buttons, stereo controls and climate controls. Fans of manual transmissions will also be happy to see this newer Renegade features a stick-shift. Part of that could be because this Renegade is probably a European model, based on where the images were taken. But seeing as this is a light refresh, and Jeep already offers a manual here, it should still be available on U.S. models, too. Also, considering how mild this update is, we would expect to see it revealed by the end of this year. Related Video:

Stellantis axed the SRT engineer team, but performance isn't going away

Stellantis has broken up the Street & Racing Technology (SRT) engineering team that created over a dozen high-performance vehicles, including the Dodge Charger Hellcat, but the situation isn't as dire as it sounds. The newly-formed company assigned SRT's former engineers to different positions, where they'll continue to make hot rods. "All of the core elements of the SRT performance engineering team have been integrated into our company's global engineering organization," a spokeswoman told enthusiast website Mopar Insiders. She added that integrating SRT's personnel into other brands in the Stellantis portfolio will ensure that the lessons learned from decades of peddling speed will permeate other products. Previously, SRT operated with a high degree of independence. Don't get too excited. Her statement does not necessarily mean that Citroen will begin building cars powered by the Hellcat engine, though a C3 Chat D'enfer sounds absolutely epic. Technology transfer will likely be limited to fields like aerodynamics and thermal management, and the design department might learn a couple of neat new tricks. Dodge will still move forward with the development of its next SRT-branded cars; the decision to dissolve the SRT team will not affect future models, according to the spokeswoman. Whether they'll be powered by a V8 is up in the air, because company boss Tim Kuniskis warned that regulations are killing the eight-cylinder engine. Similarly, Jeep will continue designing high-performance models, like the Grand Cherokee Trackhawk. What changes is that the model will be developed and designed by a group of engineers and designers from Jeep, not from SRT. SRT is dead, but performance isn't going away. SRT's demise nonetheless marks the end of an era for Chrysler. The division traces its roots to 1989, when some of the company's brightest minds were brought together to develop the first-generation Dodge Viper. It merged with Team Prowler to form the Specialty Vehicle Engineering (SVE) group, which was renamed Performance Vehicle Operations (PVO) in 2002 and finally dubbed SRT in 2004. SRT has operated as the carmaker's in-house tuner since, its resume includes a diverse selection of cars ranging from the Neon SRT-4 to the 1500 TRX, and it was promoted to a standalone brand led by designer Ralph Gilles in 2011. Fiat-Chrysler Automobiles (FCA) axed the SRT brand in 2014 but kept the name and the development team. Related video:
