Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).

Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.

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:
