Jeep CEO details the next Wrangler's push for efficiency

Jeep CEO Mike Manley's brief for the new Wrangler is a simple one – don't mess it up. But in that pursuit of keeping things proper, the affable Englishman has revealed that the brand is trying to walk a fine line while bringing its most iconic model into the 21st century. That's most important on the car's exterior. Like other long-serving American vehicles, the Wrangler is defined by its image. But even with aerodynamics playing a bigger role on the JK's successor, Manley was adamant during a conversation with Automotive News that the boxiness will carry on. "You have to be very careful with the aero of Wrangler, because at the end of the day, it needs to be recognizable as a Wrangler," Manley told AN. "To some extent that restricts you on some of the aero that you can do." Spy photos show a more rakish windshield and fascia, both key moves to lessen the aerodynamic impact of the Jeep's traditionally brick-like design. "But with weight and a number of the changes that we've made, you're going to see that we've really pushed that vehicle forward in terms of its fuel economy." The context of that last sentence points to a weight savings, something Automotive News backs up. While the Wrangler won't go all-aluminum, its frame is going to be lighter and stronger, and it will use aluminum for certain "hang-on" body parts. But this push for weight savings won't extend to the Wrangler's intangibles. It'll still ride on a body-on-frame architecture and feature solid axles at both ends, for example. Combine Manley's comments and AN's reports with news that the Wrangler will use an eight-speed automatic and offer diesel and four-cylinder turbo power in its next generation, and it's clear Jeep is trying to make the biggest strides in decades without alienating its die-hard fans.

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).
