Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.

Are future vehicular hacks inevitable?

Before the hack of the Uconnect system in a Jeep Cherokee resulted in a 1.4-million vehicle recall, the potential software vulnerabilities in vehicles were already a hot topic with Congressional inquiries and even proposed legislation in the US. As cars' interconnected systems gain the ability to go online, they become open to a host of new threats. Automakers are trying to stop this, but it might be too late to put the genie back into the bottle. Throughout 2015, the issue of software security in vehicles has become increasingly vital. For example, the recent Jeep case wasn't even the biggest hack this year. In February, a major flaw was discovered in the BMW Connected Drive service that allowed researchers to remotely lock and unlock the doors and potentially affected 2.2 million cars. The fix was an over-the-air patch for the problem. Automakers are actively working to fix the issues. Mercedes-Benz, BMW, and Audi reportedly are using encrypted connections and firewalls in their vehicles to prevent hacking. "Absolute, 100-percent safety isn't possible," Daimler spokesperson Benjamin Oberkersch said to Automotive News Europe. "But we develop our systems, tested by internal and external experts, so they're up to date." These vulnerabilities seem to be popping up more often. A successful hack took $14 in parts from Radio Shack in one case. There was also a 60 Minutes report earlier in the year about DARPA's ability to hack into OnStar to take control of a Chevrolet Impala. Experts aren't so sure companies can contend with hackers' advancement. "The difficulty for the carmakers at the moment is the question whether they can keep pace with advances in technology, and especially hacking technology," Rainer Scholz, executive director for telematics consultant EY, said to Automotive News Europe. "We seriously doubt they can." At this point, vehicle hacks are coming more from researchers looking for holes than from those with malicious intent. Still, the vulnerabilities are definitely there. It's up to automakers to keep patching the problems before they become dangerous to drivers.

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.
