Watch this 840-hp Jeep Grand Cherokee SRT8 walk away from GT-Rs and M3s

This last-generation Jeep Grand Cherokee SRT8 does things that SUVs just shouldn't be able to do, like win drag races against tuned Nissan GT-R and BMW M3 coupes. Granted, the owner isn't coming into this fight with a stock Jeep – far from it. In addition to twin turbos whistling away, he says the engine is a 449-cubic-inch V8, which is nearly 7.4 liters of displacement. As it runs here, the driver claims that the turbos are pumping out around 14 psi of boost to give an estimated 840 horsepower. What's more, he further maintains the powertrain could reach around 1,200 hp with things fully cranked up. Even somewhat dialed back, this Jeep is ready to take on a breadth of formidable challengers, including a couple of Chevrolet Corvette models and a Lamborghini Aventador. Check out the video to see how this menacing Grand Cherokee fares in a day at the races.

Jeep spied testing Hellcat-powered Grand Cherokee Trackhawk

The Jeep Grand Cherokee Trackhawk is coming. We know this, because Mike Manley, the head of Jeep, said so. We showed you this brief spy video a while back, but now we have our clearer images of the Trackhawk undergoing testing. And it looks just like a normal Grand Cherokee SRT. Yeah, anti-climactic, we know. The four shots we have show a bit of camo over the front bumper and grille, likely concealing a tweaked design or visible bits of the 6.2-liter, supercharged V8. It looks like there's a rather substantial opening below the upper grille, almost like a ram-air system. There's also a smidge of what looks like tape on the front wheel arches, although this might not mean much of anything. What's interesting is what isn't here. There's no perceivable change to the back of the car. The exhaust pipes look like they're about the same size, there's no noticeable changes to the aerodynamics, and in fact, there's not even any camouflage. Jeep also hasn't updated the Grand Cherokee Trackhawk's hood, which is somewhat surprising considering the changes for every other Hellcat-equipped vehicle (concepts included). You can check out our earliest look at the Trackhawk up top. As for when this monstrous Grand Cherokee will debut, we're expecting it to arrive sometime in 2017, perhaps on FCA's home turf at the Detroit Auto Show. Related Video:

NHTSA, IIHS, and 20 automakers to make auto braking standard by 2022

The National Highway Traffic Safety Administration, the Insurance Institute for Highway Safety and virtually every automaker in the US domestic market have announced a pact to make automatic emergency braking standard by 2022. Here's the full rundown of companies involved: BMW, Fiat Chrysler Automobiles, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Tesla, Toyota, Volkswagen, and Volvo (not to mention the brands that fall under each automaker's respective umbrella). Like we reported yesterday, AEB will be as ubiquitous in the future as traction and stability control are today. But the thing to note here is that this is not a governmental mandate. It's truly an agreement between automakers and the government, a fact that NHTSA claims will lead to widespread adoption three years sooner than a formal rule. That fact in itself should prevent up to 28,000 crashes and 12,000 injuries. The agreement will come into effect in two waves. For the majority of vehicles on the road – those with gross vehicle weights below 8,500 pounds – AEB will need to be standard equipment by September 1, 2022. Vehicles between 8,501 and 10,000 pounds will have an extra three years to offer AEB. "It's an exciting time for vehicle safety. By proactively making emergency braking systems standard equipment on their vehicles, these 20 automakers will help prevent thousands of crashes and save lives," said Secretary of Transportation Anthony Foxx said in an official statement. "It's a win for safety and a win for consumers." Read on for the official press release from NHTSA.
