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).

Hands on with the concepts of the Moab Easter Jeep Safari

Jeep has a way of tugging at the heartstrings of its enthusiastic owner base when the annual Moab Easter Jeep Safari rolls around. The 2015 version sees all boxes ticked in the off-road event's 49th year: multiple diesel engines on display, a pickup-truck-like model and more than a few nods to the brand's long and storied history book. We were able to get a first-hand look at the seven concepts being shown in Utah's Red Desert in the much cooler, cleaner confines of the FCA Technical Center's Design Dome. Jeep Chief Concept We aren't sure if it's that throwback chrome grille or the eye-catching Ocean Blue paint, but even more than the Red Rock Responder, the Chief drew our eye as soon as we walked into the Design Dome. It's a surprisingly tall vehicle, but it's also very wide. We'd also wager it's longer than your typical four-door Wrangler. Jeep may have used a Wrangler as a base for the Chief, but any similarities to the donor vehicle are extremely difficult to spot. The fenders and doors are probably the biggest giveaways, but you're going to need to squint (and have the benefit of a Wrangler to compare with, like we did) to pick out Wrangler bits. As is the recurring theme throughout all seven concepts, the Jeep design team's attention to detail is borderline fanatical. From the "Surf Rated" badge on the fenders, to the tweaked door handles to the bumper stickers in the cargo area and the Tiki-statue-shaped shifter, the little details are truly the stars of the Chief Concept. The rosewood trim in the rear cargo area is stunning and adds to the Beach-Boy-friendly stylings of the Chief. The throwback grille, round headlights and tall, skinny taillights, meanwhile, add a lot of personality to the exterior. The high beltline and lower roof gives the Chief a chop-topped look, but it's arguably the least successful element to the blue concept's otherwise impressive design. All of the vehicles Jeep put together for Moab are 100-percent functional. That's not surprising with some of the vehicles you'll see below, but it somehow is remarkably impressive given the degree of the changes Jeep made in putting together the Chief. Jeep Wrangler Red Rock Responder The Wrangler-based Red Rock Responder is arguably one of the most capable of these real-world vehicles, both in terms of the way it looks and its actual hardware. We mentioned the special rescue equipment fitted to the bright-red, truck-like Jeep – a compressor and air gun, sockets, tow straps, etc.

EU finds Jeep Grand Cherokee and Suzuki Vitara break emissions rules

AMSTERDAM — Fiat Chrysler's Jeep Grand Cherokee and Suzuki's Vitara diesel models both break emissions rules and must be fixed or face a ban on sales across Europe, the Dutch road authority ruled on Thursday. The RDW authority, acting as the reference regulator for across the European Union, said Jeep had developed a software fix and that the authority had ordered the company to recall the model across Europe to roll it out. It added Suzuki had yet to find a credible solution for the Vitara. "Suzuki must come with adequate improvement measures or the RDW will begin the process of revoking its European type approval," the RDW said in a statement, adding it had also started the process of revoking approval for the Jeep Grand Cherokee as a "precautionary measure." Regulators across the world have been testing diesel models since Volkswagen admitted in 2015 that it used illegal software to cheat U.S. emissions tests. The RDW said it had found both the Jeep Grand Cherokee and Vitara had used "prohibited emissions strategies" that led them to emit higher levels of harmful nitrogen oxide (NOx) on the road than under testing conditions. Dutch State Secretary for Infrastructure, Stientje van Veldhoven, said in a letter to parliament she would inform prosecutors of the RDW's findings. Fiat Chrysler and Suzuki could not immediately be reached for comment. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
