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.

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.

Jeep in St. Louis hacked from Pittsburgh

One of America's most popular vehicles contains a security flaw that allows hackers to remotely commandeer it from anywhere on the planet. Cyber-security researchers Chris Valasek and Charlie Miller say they've accessed critical vehicle controls on a 2014 Jeep Cherokee that allowed them to remotely control critical vehicle functions like braking, transmission function, and steering. Automakers have downplayed the possibility a car could be remotely compromised, but the significance of the findings detailed Tuesday could cause them to reevaluate the threats posed to hundreds of thousands of vehicles already on the road. A key finding – the pair needed no physical access to the Jeep to pull off the attack. Valasek and Miller accessed the controls via a security hole in the Sprint cellular connection to Chrysler's UConnect infotainment system. In the course of their research, Valasek sat in his Pittsburgh home and remotely manipulated Miller's Jeep as he drove along a highway outside St. Louis. If you know a car's IP address, they say, a hacker could control it from anywhere. "We didn't add anything, didn't touch it," Valasek told Autoblog. "A customer could drive one of these things off a lot, and they'd have no clue it had these open attack surfaces." Remotely, he disabled brakes, turned the radio volume up, engaged windshield wipers and tampered with the transmission. Further, they could conduct surveillance on the Jeep, measuring its speed and tracking its whereabouts. They conducted the experiments over multiple breaches. They made their findings public on the same day the National Highway Traffic Safety Administration, the federal agency in charge of vehicle safety, released its latest report on the readiness of government and automakers to fend off these sorts of cyber attacks. Later today, two US Senators are expected to introduce legislation that would help consumers better understand the potential risks of car hacking. In the early stages of their research, Valasek and Miller found a security flaw in the car's wi-fi that allowed them to remotely manipulate controls from a range of about three feet. But in recent months, they found another vulnerability in the Sprint cellular connection in the UConnect system. That was a key breakthrough. "Lo and behold, we found we could communicate with this thing using cellular, and then more research, and 'Holy cow,' we're using the Sprint network to communicate with these vehicles," Valasek said.
