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).

Ram and Jeep diesel emissions allegations spur class action lawsuits

This shouldn't come as a surprise. Last week, the EPA issued a notice of violation to FCA after it determined that Jeep and Ram installed eight undisclosed auxiliary emissions control devices on diesel vehicles. Since then US law firm Heninger Garrison Davis, LLC and Canadian firm Sotos LLP have launched class action suits on behalf of owners. These latest lawsuits are unrelated to a previous class action suit brought against FCA and Cummins over NOx emissions in 2007 to 2012 Ram models. The violation notice – and the subsequent lawsuits – covers 2014 to 2016 Jeep Grand Cherokee and Ram 1500 models equipped with the 3.0-liter turbodiesel V6, a total of about 104,000 vehicles in the US. The EPA says that while the emissions control devices aren't necessarily illegal, installing them without disclosing them to the EPA is, as they produce more emissions in real world use than in testing. Skirting certification in this way might be a violation of the Clean Air Act. FCA could see fines of up to $45,000 per vehicle, depending on the outcome of the EPA investigation. FCA denies that these are cheat devices, and has proposed software updates to bring the vehicles into compliance. As for the lawsuits, Heninger Garrison Davis says that "Fiat Chrysler marketed those vehicles as environmentally friendly with enhanced fuel efficiency, better performance, and lower emissions. Although the diesel vehicles were successfully marketed as 'clean,' their environmentally-friendly representations were deceptive to consumers." The suit seeks an undisclosed amount of compensation for owners of these vehicles. In Canada, Sotos LLP is seeking $250 million in damages on behalf of owners. This suit, filed in the Ontario Superior Court of Justice, also claims deception on the part of FCA, "resulting in losses and damage" to owners. These are similar claims to group actions against Volkswagen with regard to its diesel emissions cheating scandal. While VW is fixing or buying back many of the affected vehicles, the company is defending itself against some suits on behalf of owners, saying it expects " no decline in the residual values of the affected vehicles as a result of this issue." Don't be surprised if FCA mounts a similar defense.

Jeep Grand One and Quicksand Concepts lead the charge to Moab

Jeep's past, present, and future all share equal billing at the 51st annual Easter Jeep Safari in Moab. We're suckers for vintage Jeeps, so the all-new Grand One Concept really stands out among the seven vehicles that make up Jeep's conceptual take on the off-road event. It's based on a 1993 Grand Cherokee in a slightly early celebration of the model's 25th anniversary. Exterior mods include custom fender flares for clearance over 18-inch wheels and 33-inch BFGoodrich Mud-Terrain KM2 tires, trimmed front and rear fascias and what FCA is calling a "subtle wood grain" splashed on the vehicle's bodysides. An extended wheelbase ought to offer a bit more room inside, and a two-inch suspension lift will help when the going gets tough. No alterations are mentioned to the vehicle's 5.2-liter V8 or 4-speed automatic transmission. The second most interesting concept for Moab is the Jeep Quicksand. It's clearly Wrangler-based, but instead of a traditional rock-climbing focus, this one's built for the sand dunes. Power comes from a worked-over Mopar 392 Crate HEMI engine topped with an eight-stack fuel injection system that peeks through the hood. A six-speed manual sends the ponies to all four wheels, but with a unique twist: 32-inch BFGs in the front and 37s in the rear in what Jeep says is its first application of staggered tire sizes on a concept vehicle. A Warn winch concealed in a vintage-style Moon tank at the front is the finishing touch. The Jeep Safari Concept is all about letting the outdoors in while keeping the elements out. A translucent hardtop and four aluminum and clear vinyl doors are the most obvious changes from stock, and two rear seats have been angled outward so that their occupants get a better view outside. Dana 44 axles and a two-inch suspension lift come from the Mopar parts catalog, but the roof-rack-mounted drone and dash-mounted iPad are custom one-off touches. Power comes from a stock 3.6-liter V6 and five-speed automatic transmission. Perhaps more intriguing than all the custom bits and baubles, though, are what appears to be next-gen Wrangler bodywork. Take a look at the kinked grille, the outer slats of which are pinched by the headlights, and the shape of the rocker panel between the front and rear door. No, this isn't exactly a 2018 Wrangler hiding in plain sight, but it's certainly a nod toward the future. Jeep's Switchback Concept looks to be a rolling Mopar parts catalog.
