2018 Jeep Grand Cherokee TrackHawk shows off its hellish supercharged V8

We've seen the spy shots of this thing, the 2018 Jeep Grand Cherokee TrackHawk, before. But only from the outside. The external changes are plenty telling, but there was always the slight chance we were looking only at an extra-hot SRT version, not a full-blown (pun intended) TrackHawk with a Hellcat motor. Until the hood goes up, there's no telling what we're really looking at. Well, seeing is believing. We have been looking at TrackHawks all along. And Mike Manley, Jeep's CEO, wasn't selling the world a bill of goods when he said to expect the thing "by the end of 2017". As you can clearly see in the slightly noisy engine shot, that's a supercharger parked on top of FCA's 6.2-liter V8, just like in the Charger and Challenger Hell-twins. Chances are it'll make the same power as it does in those two – 707 hp, in case you're just waking up from cryo-stasis and aren't aware of the most famous power output figure on the planet. There are some differences between this Grand Cherokee and ones we've previously pegged as TrackHawks. The fog lights in the lower grille vents are gone, and the rear fascia gets a bit more aggressive. Perhaps these will be the external details that separate the TrailHawk from the lowly non-supercharged SRT versions. We've also been hearing about quad exhaust tips, but haven't seen them on a prototype yet. If Jeep wants to get this thing out on the road by the end of the year, we're likely to see it coming to an auto show soon. Keep your eyes peeled. Related Video:

Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

How to update and secure a vulnerable Chrysler Uconnect system

If you own one of the 1.4 million vehicles affected by the recent Chrysler software recall, you may want to watch this video. In it, we explain how to get the latest infotainment software loaded onto the 8.4-inch Uconnect system. The recall was a response to the findings of researchers who were able to hack into and remotely control a 2014 Jeep Cherokee through its cellular connection. Although Fiat Chrysler has worked with Sprint to plug most of the holes on the carrier side, there are still some vulnerabilities that only this latest software version can patch. Owners have three options to get the update: download it now, wait for a USB stick in the mail, or take the vehicle to an FCA dealer. Chrysler will be sending USB sticks loaded with the software update to customers. Anyone with an internet connection and a USB stick of their own with at least 4 GB capacity can speed things up by downloading the patch from the Uconnect website. We cover that process from start to finish in the video, with the final portion still applicable to those using the FCA-supplied USB stick. If after watching this you still don't want to tackle the patch yourself, you can take your vehicle to the dealer to have it done. Also note that this process is the same for all Uconnect updates, not just the one patching the exploits. Our demonstrator vehicle is a 2015 Ram 1500 pickup. The procedure should be very similar on other products with the 8.4-inch Uconnect system, with only the location of the USB port varying. Once you have the USB stick with the software on it – either after having downloaded it yourself or receiving it in the mail from Chrysler – the installation process is relatively simple. It takes about 15 minutes to perform the update; we edited out the wait in the video. To check whether or not your car's 8.4-inch Uconnect system is running the latest software, go to System Information on the touch screen's Settings page and look at Software Version. The update related to the recall is version 15.17.5. Related Video: Recalls Chrysler Dodge Jeep RAM Safety Technology Infotainment Videos Original Video hacking
