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).

2018 Jeep Wrangler spy shots give us best look yet

A couple weeks ago, we got a fairly comprehensive set of 2018 Jeep Wrangler spy shots. For fans of the JK-series Jeeps, it was all good news: the basic Wrangler Unlimited formula and shape is present and accounted for, meaning this new Wrangler will be an evolution of the current SUV, rather than a ground-up reimagining. The new shots give us some more detail than we had previously, and let us point out some JL Wrangler features that reaffirm FCA's conservative approach. First of all, the heavy camouflage doesn't manage to fully cover the exposed door hinges, just like in the current model, so those are a safe bet for the production version. The raked-back windshield might lose its ability to fold down, we've heard. The JL remains a body-on-frame truck with a solid front axle, evidenced by the front diff peeking out and the radius arms connected to them. The large exterior mirrors also appear to be carryover items, and the taillights look indistinguishable from the current JK. We expect the front fascia to remain clearly recognizable as a Wrangler, but don't be surprised if the headlight and sidemarkers incorporate some LED elements as a nod to current trends. Remember, the JL will spawn a pickup version, and will slim down for better fuel economy with some aluminum elements, likely incorporated in the body. We expect the Pentastar V6 to carry over, but be joined by a diesel and a mild hybrid at some point in the future. It'll be built alongside its JK predecessor for a short time in Toledo, Ohio.

These cars are headed to the Great Crusher In The Sky

It happens every year. We bid adieu to some cars and trucks that will be missed, and say good riddance to others wondering how they stayed around so long. Whether they're being killed off for slow sales or due to a new product coming along to replace them, the list of vehicles being discontinued after 2012 is surprisingly long and diverse.
CNN Money has compiled a list of departing vehicles, to which we've added a few more of our own. In the slow sales column, cars like the Lexus HS 250h, Mercedes-Benz R-Class and the full Maybach lineup appear, while the Ford Escape Hybrid, Mazda CX-7 and Hyundai Veracruz are all having their gaps filled with more modern and more fuel-efficient alternatives. Obvious exceptions to the rule include models that still sell in decent numbers like the Jeep Liberty and the Chrysler Town & Country (which will eventually be replaced by a crossover-like vehicle).
