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:

Everything we know about the 2018 Jeep Wrangler JL

The 2018 Jeep Wrangler JL is perhaps the most highly anticipated SUV in America. The next-gen Wrangler is expected to get a host of updates that include new front and rear end designs, as well as an all-new pickup truck variant. Here's everything we know about the next version of Jeep's iconic SUV. November 7, 2016: JL Wrangler Forums released renderings of the 2018 Wrangler, and the SUV will generally stay the course. Compared with the current Wrangler, the new one will likely have slightly more aerodynamic bodywork and LED lighting, and the truck version's bed will carry traditional Wrangler design cues. The renderings also visualize what a Wrangler without a fully removable top could be like. The loss of the removable top is currently a rumor, and FCA's well-camouflaged prototypes have not given up the secrets of the roof. View 6 Photos October 18, 2016: Images of the upcoming Wrangler JL from a supposed Jeep dealer meeting surface, revealing the SUV's updated front and rear end design. The renderings point towards the next-gen Wrangler maintaining a seven-slot grille and round headlights. The SUV, though, will obtain LED light bars on the front fenders, while the taillights get a similar design to the units found on the Renegade crossover. Overall, the renderings display a smoother shape than ever before. September 16, 2016: A report from JL Wrangler Forums indicates that the next-gen Wrangler JL would utilize aluminum on the hood, as well as on the front and rear doors. The report claims the Wrangler will get its aluminum from supplier Alcoa, in the form of the company's C6A1 high form alloy, 6022 alloy sheet, and A951, which is the company's sheet bonding technology. View 30 Photos July 20, 2016: The first images of the Wrangler pickup truck hit the web. The pickup truck appears to be riding on a long-wheelbase Wrangler and flaunts a decently sized bed. From the overhead photos, we can see that the pickup truck will have a seven-slot grille, large rear taillights that mimic ones found on Ram's trucks, and be about the same size as a Chevrolet Suburban. Oh yes, the Wrangler pickup truck does exist and it's coming. July 10, 2016: A report from Automotive News claims that the Wrangler JL will continue to have its iconic, boxy shape, but changes have been made to ensure that the SUV is better off in terms of fuel economy. What Jeep has done to improve the next-gen Wrangler's fuel efficiency, though, is still a mystery.

Watch a Cayenne Turbo S, Range Rover SVR, and Cherokee SRT drag race

We live in a weird world where high-performance SUVs could win a 60-mile-per-hour sprint against sports cars from just a few years ago. Here, Top Gear sets up a three-way drag race against the Porsche Cayenne Turbo S, Land Rover Range Rover Sport SVR, and Jeep Grand Cherokee SRT, and the results show just how quickly these high-riding models can cross the quarter mile. The Cherokee SRT is the patriotic choice among the three, but it's down on power in this fight. Meanwhile, the Range Rover's menacing growl sounds the best, and the Cayenne Turbo S has the most horsepower. You'll have to watch the video to see which SUV will win this battle. Related Video:
