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).

2019 Jeep Renegade Limited and Trailhawk revealed with updated styling

A few weeks back, we got our first glimpse of the refreshed 2019 Jeep Renegade. The Italian-built compact crossover is currently the smallest model in Jeep's lineup. Details were scarce, but we now have some new info on the European-spec model as well as a whole batch of photos of both the Renegade Limited and Renegade Trailhawk. Visually, both the Limited and Trailhawk models get revised front fascias with dark LED and Xenon lighting that mimics the new Jeep Wrangler JL. The Limited's bumper includes more body-color panels with new turn signals, fog lights and a lower air intake. Outside of the new lighting, the only real change to the front of the Trailhawk is the lack of a bright red front tow hook. In the rear, both models get new taillights, though the bumpers appear to be the same. The Renegade Limited now comes with 19-inch wheels. The Renegade now has new gasoline and diesel engines, though it's unclear which — if any — will make it to the U.S. market. There's a 1.0-liter turbo inline-three that makes 120 horsepower, a 1.3-liter turbo inline-four that makes either 150 or 180 horsepower. That makes it as powerful as the 2.4-liter naturally-aspirated inline-four that's currently available. The 1.6-liter and 2.0-liter turbo diesel engines — not available in the U.S. — both get updated European emissions equipment. There are three transmissions: a six-speed manual, a six-speed dry dual-clutch and a nine-speed auto. The Renegade is still available with both front- and four-wheel drive. There are two four-wheel drive systems, with one slightly more sophisticated system reserved for the Trailhawk. Other carryovers include the removable My Sky roof panels and most of the interior. The Renegade also gets the latest version of FCA's UConnect infotainment system that is compatible with Apple CarPlay and Android Auto. Pricing hasn't been announced, but look for U.S.-specific details sometime later this summer. Related Video:

Chrysler taking big risk snubbing NHTSA

Maker Insists Feds Overstate Risk Of Fires With Grand Cherokee, Liberty Models
It's not often that recall stories make it above the fold, in that old newspaper parlance, but when one shows up as the lead story on the network evening news programs, you know it's something big.
And so it is with Chrysler snubbing its nose at a request by the National Highway Traffic Safety Administration to recall 2.7 million Jeeps the feds insist are at risk of potentially catastrophic fuel tank fires in a rear-end collision.
