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).

How to update and secure a vulnerable Chrysler Uconnect system

If you own one of the 1.4 million vehicles affected by the recent Chrysler software recall, you may want to watch this video. In it, we explain how to get the latest infotainment software loaded onto the 8.4-inch Uconnect system. The recall was a response to the findings of researchers who were able to hack into and remotely control a 2014 Jeep Cherokee through its cellular connection. Although Fiat Chrysler has worked with Sprint to plug most of the holes on the carrier side, there are still some vulnerabilities that only this latest software version can patch. Owners have three options to get the update: download it now, wait for a USB stick in the mail, or take the vehicle to an FCA dealer. Chrysler will be sending USB sticks loaded with the software update to customers. Anyone with an internet connection and a USB stick of their own with at least 4 GB capacity can speed things up by downloading the patch from the Uconnect website. We cover that process from start to finish in the video, with the final portion still applicable to those using the FCA-supplied USB stick. If after watching this you still don't want to tackle the patch yourself, you can take your vehicle to the dealer to have it done. Also note that this process is the same for all Uconnect updates, not just the one patching the exploits. Our demonstrator vehicle is a 2015 Ram 1500 pickup. The procedure should be very similar on other products with the 8.4-inch Uconnect system, with only the location of the USB port varying. Once you have the USB stick with the software on it – either after having downloaded it yourself or receiving it in the mail from Chrysler – the installation process is relatively simple. It takes about 15 minutes to perform the update; we edited out the wait in the video. To check whether or not your car's 8.4-inch Uconnect system is running the latest software, go to System Information on the touch screen's Settings page and look at Software Version. The update related to the recall is version 15.17.5. Related Video: Recalls Chrysler Dodge Jeep RAM Safety Technology Infotainment Videos Original Video hacking

Jeep Comanche Moab Concept: Hell yeah!

The moment I saw the Jeep Renegade I knew it was a winner, at least in terms of styling. The Renegade's "face" is exactly what small 21st-century Jeeps should look like. It has loads of Jeep's visual heritage DNA – important! – that has been brought up-to-date in the best possible way. (Now if only they could graft that face on to the new-ish Cherokee...). Where the Renegade falls short is what's under the skin. Thanks to misguided marketing, it is saddled with a rather unremarkable USA-spec 2.4L four, undersized tires, so-so ground clearance, an iffy 9-speed automatic, and a questionable (available) low range. I don't mind the independent suspension; in fact I embrace it, as IFS/IRS is the future in terms of off-road suspension design. So, for me, the Renegade is a close-but-no-cigar vehicle, at least as it currently stands. This new Comanche, however, shows how the Renegade can evolve; both as a 4-door SUV, and in terms of how spin-off models can be developed. Big beefy tires, flared out fenders, and great ground clearance are the main ingredients that make this work visually. Still wish for a 3.6L V6 under the hood, but the 2.0L diesel isn't a bad alternative. Anyway, I think a Comanche pickup makes more sense than the predicted Wrangler-based pickup. Why? I'm not big on retro-vehicles in general. Rarely do they survive long term. Besides, the Comanche would be far more civilized and livable. I could see this Comanche pickup as a daily driver much more so than a Wrangler-based pickup. Yeah, I like and value creature comforts over ultimate off-road ability. I think most pickup buyers would agree. Finally, while there is a large devoted Wrangler following who would love a Wrangler-based pickup, I bet this Renegade-based Comanche would bring more new customers into the Jeep tent – especially over a much wider age demographic.
