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 Renegade and Fiat 500X finally on the way to dealers

After a brief pause, the Jeep Renegade and Fiat 500X are on their way to dealers again. While initially reported as a software bug, the issue had nothing to do with the models themselves. According to a statement from FCA US to Autoblog, the "vehicles were built with an atypical Vehicle Identification Number that may not be recognized as valid by some computer systems." That problem has now been fixed. FCA US held the compact crossovers back from dealers until the company could rectify the bug. If the CUVs had been delivered, there would have been difficulty registering the vehicles, according to Automotive News. Before discovering the situation, about 20 of these Renegades were sold to customers. FCA CEO Sergio Marchionne originally discussed the predicament in late May. "I'm having a very bad engineering day," he said. "It's a combination of attributes of that vehicle that is making my life horrible." While the boss predicted the problem would be fixed as late as mid-June, the company apparently got things working much quicker than that. Related Video: FCA US Statement A limited number of 2015 Jeep Renegade and 2016 Fiat 500X vehicles were built with an atypical Vehicle Identification Number (VIN) that may not be recognized as valid by some computer systems. This VIN issue has been resolved. FCA US has been working with governmental agencies, insurers and financial institutions with whom customers may interact to ensure successful registration, financing and insurance coverage. Renegade and 500X vehicles are being shipped and are in stock at dealerships for purchase. The VIN issue is entirely separate from the operation of the vehicle.

Next Jeep Wrangler to get hybrid option?

This may the year a Jeep hybrid is officially announced. Really. The Chrysler division may finally be making plans for its first gas-electric powertrain to help boost the group's fuel economy, says UK's Auto Express, citing Mike Manley, CEO of FCA's Jeep division. The guinea pig of sorts may be the Wrangler, which moved almost a quarter-million units in the US last year. The Wrangler could get a hybrid drivetrain by the 2017 model year, as Jeep executives look to maintain the model's feel and torque while boosting its fuel economy. The Wrangler gets a pretty paltry 18 miles per gallon combined out of its six-cylinder mill, so the bar's set pretty low. Of course, we've heard this talk before. In late 2013, Chrysler Asia-Pacific product planning manager Steve Bartoli told Australia's Drive that a Jeep hybrid was pretty much inevitable, though not much has been mentioned since. FCA could use all the help it can get in the fuel economy department. The group brought up the rear among automakers when it came to fuel efficiency, the US Environmental Protection Agency (EPA) said in its EPA Trends report released last October. The FCA models combined for a 21.1 miles per gallon average for the 2014 model year, compared to the 24.2 mpg overall industry average. The group's only electric vehicle in the US is the low-volume Fiat 500e, though the company may start selling a plug-in hybrid version of its Chrysler Town & Country by the end of the year.
