Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

Weekly Recap: Hackers demonstrate auto industry's vulnerability

There's always been a certain risk associated with driving, and this week cyber security came into focus as the latest danger zone when researchers demonstrated how easily they could hack into a 2014 Jeep Cherokee from across the country. The incident raised concerns over the vulnerability of today's cars, many of which double as smartphones and hot spots. During the now-infamous experiment, Chris Valasek and Charlie Miller infiltrated the Jeep's cellular connection and were able to control the infotainment system, brakes, and other functions. The hackers told the Jeep's maker, FCA US, of their findings last year, the company devised a software fix. Though Valesek and Miller hacked a Cherokee (like the one shown above), several FCA products, including recent versions of the Ram, Grand Cherokee, Dodge Durango, and Viper were also affected, illustrating potentially wide exposure that could reverberate across the sector. "For the auto industry, this is a very important event and shows that cyber-security protection is needed even sooner than previously planned," Egil Juliussen, senior analyst and research director for IHS Automotive, wrote in a research note. "Five years ago, the auto industry did not consider cyber security as a near-term problem. This view has changed." Hours after the Cherokee hacking incident was publicized on Tuesday, Sens. Ed Markey (D-Mass) and Richard Blumenthal (D-Conn) introduced legislation to direct the National Highway Traffic Safety Administration and Federal Trade Commission to establish national standards for automotive cyber security. The bill also would require vehicles to have a cyber-rating system to alert consumers how well their cars' privacy and security are defended. "Drivers shouldn't have to choose between being connected and being protected," Markey said in a statement. "We need clear rules of the road that protect cars from hackers and American families from data trackers." Though FCA and its Jeep Cherokee were in the spotlight this time, they were just the latest to showcase how automotive technology has advanced faster than safety and regulatory measures. IHS forecasts 82.5 million cars will be connected to the internet by 2022, which is more than three times today's level. "Cyber-security will become a major challenge for the auto industry and solutions are long overdue," Juliussen said.

Jeep Renegade Hell's Revenge is the Harley rider's Jeep

Well, here's a thing. Yes, it's a Jeep Renegade. Yes, it has flames on it. And no, we aren't really sure how to feel about it. This is the Renegade Hell's Revenge. Presumably named after the Hell's Revenge Trail in Moab, this one-off baby Jeep is the product of Italian tuning house Garage Italia Customs and draws inspiration from the collected works of Harley-Davidson. It's not the first time a car company has attached the Milwaukee icon's badge to one of its vehicles – the company has a long history of partnering with Ford for special edition pickup trucks – but it's the first time we can recall the brand teaming with Jeep. The Hell's Revenge was created because of the 25th annual European H.O.G. Rally, a big Harley-Davidson festival being held in Portoroz, Slovenia this weekend. And since Europeans have a bizarre infatuation with Harleys, Jeep probably saw an excellent advertising opportunity and slotted the off-road brand in as the event's main sponsor. We have to admire the workmanship on this diesel-powered Renegade. Ignore the fact that there's a flame motif, and the actual paint job itself is absolutely lovely. According to FCA's official release, GIC used four layers of matte paint before applying fluorescent paint. The dashboard also gets a bright, exuberant flame motif, while the seats are a combination of Foglizzo Nappa leather and black denim. The functional changes are minor. BFGoodrich tires and a jacked-up suspension provide extra capability, and there are a pair of adorable LED spotlights ahead of the two A-pillars. It's an impressive effort. Really. But when you remember that the last Chrysler product to wear a flame motif was the PT Cruiser, we wonder if Jeep knew what kind of company its newest CUV would be in. Related Video:
