2018 Jeep Wrangler Spied Looking More Aerodynamic | Autoblog Minute

This week we got an early look at the 2018 Jeep Wrangler. So what we see in these spy shots, or at least we think we see, is a vehicle that?s going to use more aluminum in a bid to reduce weight and thus improve fuel economy.

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).

Supplier says Jeep Cherokee hack only affects FCA cars

Harman doesn't think that drivers need to worry about any further hacks of its products. The company supplies FCA's Uconnect infotainment system where a software vulnerability is responsible for a 1.4-million vehicle recall. "This experimental hack is unique to Chrysler," Harman CEO Dinesh Paliwal said to Automotive News. "This does not exist, to our assessment, in any other vehicle." The reason that the company wouldn't be involved is that automakers aren't simply plugging in the existing infotainment systems into new vehicles. According to Paliwal, Harman supplies the unit, but FCA and other automakers are able to make additional modifications for their vehicles. The National Highway Traffic Safety Administration has also recently taken up the question of broader software vulnerabilities in Harman's products. On July 29, the agency began investigating the company to check for similarities between Uconnect and the infotainment systems supplied to other automakers. The Jeep hack became national news when two researchers were remotely able to take control of a Cherokee. The vulnerability in the cellular connection even gave control over the brakes. "Once people get in the car and get into the CAN bus, then you can start to mimic and mess up many, many things in the car," Paliwal said to Automotive News. Politicians immediately responded with legislation to create federal standards in hopes of protecting drivers better. NHTSA also opened an investigation to make sure the automaker's software update actually solved the problem. Related Video:
