FCA Recalls Jeep in Wake of Wireless Hack | Autoblog Minute

Carjacking has gone wireless, as automakers and Congress scramble for a solution. Adam Morath reports on this edition of Autoblog Minute.

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).

Jeep going bigger with new Grand Wagoneer, smaller with sub-Renegade?

The headlines are still rolling in for the new Renegade that Jeep unveiled at the Geneva Motor Show last week, but already reports are surfacing, citing sources within the company, about what Chrysler's iconic off-road brand will do next.
Speaking with Auto Express (whose reports we tend to take with a grain of salt or two), Jeep chief Mike Manley suggested that two courses of action are currently under consideration at Auburn Hills to develop two very different new models - one smaller and one larger than anything Jeep currently makes.
One plan would be to make an SUV or crossover even smaller than the new Renegade, although it isn't immediately clear what platform it would take. The Renegade (pictured above in Trailhawk spec) will be built in Italy alongside Fiat's upcoming 500X, but uses a heavily modified platform. We figure the smaller model, if approved, could base itself on the new Fiat Panda Cross.
