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).

FCA's shifter fiasco proves novel gear selectors are a bad idea

What's wrong with PRNDL? Why are automakers trying to overly complicate the simple task of selecting gears? If there's any lesson to learn from the recent news that NHTSA is investigating 853,000 Fiat Chrysler vehicles over its problematic gear selectors, it's that the trend of fancy shifters needs to stop. Now. Last year, NHTSA opened an investigation into Jeep Grand Cherokee models, and has now expanded this probe to include the 2012-14 Chrysler 300 and Dodge Charger. The problem? The shifter – assembled by ZF – is confusing for many drivers. "Testing ... indicates that operation of the (electronic) shifter is not intuitive and provides poor tactile and visual feedback to the driver, increasing the potential for unintended gear selection," a NHTSA document states. More than 100 crashes and over a dozen injuries are linked to this problem, according to The Detroit Free Press. To us, the problem isn't just limited to FCA. These unnecessarily novel gear selectors are spreading like wildfire across the industry. Honda and Acura use a weird pushbutton setup. Lincolns have buttons on the dashboard. Jaguar's shifter electronically raises out of the center console. Mercedes uses a stalk with up-for-Reverse, down-for-Drive, push-for-Neutral arrangement. And what the hell is BMW thinking with its M cars? FCA has since abandoned the confusing shifters in question. The 300, Charger, and Grand Cherokee now use the rotary shift dial that's quickly proliferating across the company's brands. Simplistic gear selectors might not be sexy, but no one ever complained about not being able to find the right gear in a Hyundai Sonata. What's most interesting is that this NHTSA investigation could push FCA – and possibly other automakers – to redesign vehicle functions that otherwise operate as designed. Just because most people will never have a problem putting a Dodge Charger in Reverse doesn't mean there isn't a flaw with the design. But perhaps a more simplistic solution – good ol' PRNDL – would have prevented these issues from the start.

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
