Crawling Moab in the 2015 Jeep Renegade Trailhawk [w/video]

The funny thing about the Renegade Trailhawk is that Jeep still feels the need to defend it. For the past 20 years, automakers have sent emissary vehicles outside the citadel walls surrounding their brand niche. In doing so, these companies found buyers eager to join the cult instead of an angry horde. With the kingdom successfully expanded, automakers had to build new walls to contain this broader identity. This is the story of Jeep's modern expansion, growing with new models while the faithful at the brand's center howl at every quest into broader market segments. Thirteen years after it busted out the Liberty and eight years after birthing the Compass and Patriot, you'd think the resistance to new Jeeps would subside. But no. It's 2015, and while nobody makes the slightest tantrum over BMW's new minivan (except for Sniff Petrol), the Renegade still has to fight its way through pitchforks and torches. Which is a long way of saying that this author is guilty of brand prejudice, too. When the company told us that we'd spend the first day of the Easter Jeep Safari driving seven awesome concepts and the second day driving the Renegade Trailhawk on Dome Point Trail, we could only think, "They giveth excitement, and they taketh it away." Our pessimism was later proven to be incorrect. Sharing the sentiment our colleague Brandon Turkus expressed after his Quick Spin, we found the Renegade to be "in a word, impressive." Dome Point will not trouble a kitted-out Wrangler, but in a compact SUV with on-road tires the rocky sections were chunky enough to require close attention to your lines or use a spotter. As instructed, we put the little 4x4 into the Selec-Terrain's Rock mode, and with common sense plus one eye on the man directing us with hand signals the Renegade climbed over everything with some wheelspin but little fuss. At the first rest point, we turned the car off to wait for vehicles behind. Not realizing that this resets the drive mode to Auto, we crawled through the next two rocky jumbles in the default setting. The result was the same: a bit of wheelspin climbing over thick steps, but an altogether drama-free passage. Auto mode can't use the engine throttle maps unique to each Selec-Terrain setting, but it doesn't hamper the Renegade's capability by much. On a steep bit of trail with a crest capped by stacked stone plinths, it took three tries to find the right line, but that's on us – the Renegade did more than expected.

Jeep Renegade sales being held due to powertrain issue [UPDATE]

UPDATE: An unnamed FCA US source has clarified to Automotive News that while there is a software issue, it does not concern the transmission. The Jeep Renegade appears to be facing early software problems that are similar to the ones at the introduction of the Cherokee a few years ago. The issue is keeping the brand's latest compact crossover away from dealers until the situation can be resolved. The fault reportedly deals with the software controlling the Renegade's nine-speed automatic transmission. FCA CEO Sergio Marchionne briefly talked about what was happening in an interview with Automotive News. "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." The company boss predicted at the longest it could take until mid-June to fix things. Through April, Jeep has sold 5,157 Renegades, including 4,214 of them in that month alone. Autoblog reached out to an FCA US spokesperson to learn more about the software problem, but the company had no comment. Getting the software right to control the nine-speed automatic plagued development of the Cherokee. The issues delayed the model's launch in 2013, and the company was still releasing improvements for some vehicles this year.

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).
