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 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.

Jeep Renegade to show off new Mopar gear in Detroit

Jeep's adorable new Renegade is arriving in the US market soon (we're looking forward to driving it in a couple weeks), and to highlight that fact, the American off-road brand is trotting out a pair of Mopar-modified compact CUVs for the 2015 North American International Auto Show. Rather simply, Jeep has modified one Renegade to show off its prowess in the city, and another that plays up the crossover's off-road abilities. Despite their different purposes, both vehicles show off Mopar's parts catalog and Jeep's Authentic Accessories lineup for the new baby Jeep. The Urban Renegade borrows uses a Renegade Limited with Anvil paint as its base and draws from the Accessories catalog, adding a number of Omaha orange accents and satin black wheels. Mopar donated a bike-hauling trailer hitch to the rear of the Renegade, while its cabin features Katzkin leather-lined seats. Once again, Omaha orange accents brighten up the Limited's cabin. As for the off-road model, Mopar got a bit more involved, starting with the Renegade Trailhawk and adding satin black wheels with Colorado red trim and X-shaped graphics, borrowed from military jerry cans, to the Commando Green exterior. A number of prototype and one-off body mods were fitted to the Trailhawk, including a concept skid plate, rock rails and a new rear valence. Inside, Katzkin leather was applied to the Renegade's seats while the Omaha orange accents from the Urban Renegade have been replaced with Commando Green bits and bobs in the off-road model. Look for more on these new Renegade twins come Monday, when we hit the floor of the 2015 Detroit Auto Show. Until then, check out the official press release from Mopar.
