Jeep Cherokee on 2040-cars

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 first American carmaker to return to Tokyo show

Despite foreign-brand car sales in Japan declining six percent in the first four months of this year, Jeep sales are up 21 percent in the same period. That could explain why Jeep will be the first the US manufacturer to return to the Tokyo Motor Show after eight years away. Ford, General Motors, and Chrysler walked away during the global crisis that struck after the 2007 show. Jeep will be part of an eight-vehicle, four-brand showcase overseen by Fiat Chrysler Automobiles Japan, the local subsidiary. For the moment, it is the only US brand to sign up - neither Ford, GM, or even Chrysler are committed to attend. Stablemates Fiat, Alfa Romeo, and Abarth will be there, along with 13 other foreign makes, answering the "Technology & Fantasy" theme for this year's event. In total, organizers announced 15 brands from 14 Japanese manufacturers, and 27 brands from 17 foreign carmakers. The show opens to the public from Oct. 30 to Nov. 8. Related Video:

Chrysler recalls 2013 Ram pickups, 2014 Jeep Grand Cherokee

Chrysler's spate of successful products is about to be marred by a trio of recalls. The Pentastar is recalling 51,477 Ram trucks and Jeep SUVs. According to the National Highway Traffic Safety Administration, there have been no reported accidents, injuries or deaths related to the affected vehicles.
The largest action covers the Ram 1500, which is seeing 45,961 trucks being recalled. Models built between June 26, 2012 and February 5, 2013 are being recalled due to a potential software issue in the electronic stability control. Apparently, the system can be randomly deactivated upon vehicle startup.
Chrysler is also recalling 4,458 2014 Jeep Grand Cherokee models. Covering everything but the SRT models, the potentially defective SUVs were built between January 14 and March 20, 2013. This recall focuses on "premium headlights," which means cars equipped with LED running lights. During the switch from the bright daytime running lamp setting to the low-intensity parking light setting, an electrical spike can cause one of the Jeep's computers to go into a safe mode, turning off the LEDs. This violates Federal Motor Vehicle Safety Standards.
