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.

NHTSA investigating 630k Jeep Wranglers for possible airbag fault

The National Highway Traffic Safety Administration is opening a preliminary evaluation into a possible wiring problem on some 2007-2012 Jeep Wrangler models that could affect airbag deployment. The government agency has 221 complaints alleging that the airbag warning light is illuminating, and that could indicate that the safety devices might not deploy in a crash. If a recall is necessary, an estimated 630,000 vehicles could be affected. According to the documents from NHTSA (as a PDF here), a "faulty clockspring assembly in the driver side airbag electrical circuit" could be the culprit. Also, some of the affected Wranglers are showing a fault code that indicates the safety device wouldn't deploy in an accident. However at this time, there are no reports of injuries related to this potential problem. NHTSA's preliminary evaluations are simply meant to investigate and don't necessarily lead to a recall. This isn't the first time for a potential problem like this on the Wrangler, though. A clockspring issue already led to a safety campaign for 2008-2012 right-hand drive Wranglers and an extended warranty for 2007 left-hand drive examples.

Several complaints cite the following diagnostic trouble code (DTC): Code B1B02 Open Squib to driver's air bag. This DTC would indicate a no-fire condition (disablement) for the driver air bag. ODI investigated the RHD (right hand drive) Wrangler for a clockspring issue under PE11-019 which led to NHTSA Recall 11V258 on model year (MY) 2008-2012 RHD Wranglers as well as an extended warranty campaign on MY 2007 LHD Wrangler vehicles. This investigation covers the MY07-12 LHD (left hand drive) Wranglers.

Jeep Wrangler Polar Edition coming to America

Jeep originally took the wraps off its Polar Edition Wrangler at the Frankfurt Motor Show in September, and at the time, we figured this would be a Europe-only affair. (Perfectly fine, since we US customers haven't exactly been lacking special edition Wrangler models over the years.) But now, and as Jeep says, just in time for winter, the automaker has announced that the ice cold Wrangler will be hitting North American showrooms in November.
Based on the Wrangler Sahara model, the Polar Edition can be had in either two- or four-door body styles, with a unique Hydro Blue paint job as the featured color. (Buyers can also opt for less-special Billet Silver and Bright White hues.) Other exterior enhancements include a body-colored hardtop, 18-inch gloss black wheels, the Powerdome (power bulge) hood, and unique decals all around the body.
But the Polar Edition isn't just about some paint and stickers. Jeep has fitted this Wrangler with a Dana 30 front axle and Dan 44 rear axle, as well as the Trac-Lok anti-spin electronic rear differential. Like all US-spec Wranglers, the Polar Edition uses Jeep's 3.6-liter Pentastar V6, producing 285 horsepower and 260 pound-feet of torque. Both a six-speed manual and five-speed automatic transmission are available.
