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).

Retro Review covers that Jeep Wrangler TJ you wanted in high school

The Jeep Wrangler TJ holds a dear place in my heart. When they were introduced, the return to circular headlights helped pull my dad into the dealer, and he bought one. A few years later, I learned how to drive a stick in that Jeep. Now, MotorWeek has fired up the time machine for a look at the '97 Wrangler as part of the Retro Review series. One of the great things about these videos is that they offer a chance to see if nostalgia lives up to reality. In this situation, that seems to be the mostly case. Even when new, MotorWeek finds a lot to praise about the TJ, especially in terms of handling and style. It's not all perfect, though, with a major complaint about the braking. Watch the clip to see if the show's take on the Wrangler lives up to your memories of them, too.

Fiat Chrysler CEO: No plans to sell brands to Chinese

DETROIT — Fiat Chrysler Automobiles (FCA) has no intention of breaking up the company or selling individual brands to China or other parties, the company's chief executive said on Monday at the Detroit Auto Show, adding that the group was counting on its coveted Jeep brand to drive future profits. "We're not going to break up anything," Chief Executive Sergio Marchionne said at a news conference at the Detroit Auto Show. "We have no intention of breaking it up and giving anything to the Chinese." Marchionne said the Jeep sport utility vehicle brand could help FCA double its net profit. FCA's portfolio also includes luxury Maseratis, sporty Alfa Romeos and tiny Fiats. FCA's share price has jumped more than 30 percent this year on a bullish outlook for the auto sector, Jeep growth expectations and speculation that Marchionne's final year at the helm could prompt strategic deals such as spinoffs, technology alliances and disposals. The popularity of the Jeep brand, which is targeting sales of 2 million vehicles this year, has prompted talk it could be spun off from the group, as happened with tractor maker CNH Industrial and supercar group Ferrari, or sold off. Rumors have resurfaced that Guangzhou Automobile Group might be interested in snapping up part of FCA. Marchionne said on Monday that while GAC has partnered to deliver Jeeps to the Chinese market and FCA is talking to the Chinese automaker about helping it enter the U.S. market, "none of these things are designed to impact on the independence of FCA." FCA has often been the subject of merger speculation, especially after its unsuccessful 2015 attempt to tie up with larger U.S. rival General Motors. Its share price jumped to record highs in August after reports of interest from China's Great Wall Motor Co and South Korea's Hyundai. Marchionne said while both Jeep and truck brand Ram are strong enough to exist on their own, "we need to talk about ... what will be left behind." Marchionne said he has recommended to the company's board that the automaker spin off Magneti Marelli, a maker of components for lighting, engines, electronics, suspension and exhausts, to shareholders by the end of 2018. Marchionne confirmed FCA's targets for 2017 and for 2018, including a plan to erase all debt and generate up to 5 billion euros ($6.14 billion) in net cash.
