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).

Consumer Reports digs Mazda3, disses Jeep Cherokee

Consumer Reports has just rendered its verdict on two of the more important cars to launch this year - the Mazda3 and the Jeep Cherokee. Considering the value a "Recommended" rating carries with the public and the viciously competitive markets these two cars compete in, Consumer Reports' view could have some impact on their initial success.
For Mazda, that's a good thing. CR spoke quite highly of the Zoom-Zoom brand's compact sedan and hatch, testing both models, and citing the excellent fuel economy and snickety-snack manual shifter as high points. Downsides to the 3 included a ride that is agile but "nervous," a bit too much noise and a cramped back seat. Still, the 3 was good enough to earn its place in the ranks of the "Recommended."
The Jeep didn't fare quite so well, with CR calling the polarizing CUV "half-baked." Although both engines were tested, the magazine called the 2.4-liter four-pot underpowered and its nine-speed automatic unrefined and unresponsive. That's particularly damning, considering the 9AT's role in future Chrysler products, including the extremely important 200. Overall, the Cherokee missed out on the coveted "Recommended" rating.
