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.

Mixed sales results, but automaker stocks rise on need for cars in Houston

DETROIT — The Big Three Detroit automakers on Friday reported better-than-expected August sales and issued optimistic outlooks for demand as residents of the Houston area replace flood-damaged cars and trucks after Hurricane Harvey, sending their stocks higher. General Motors, Ford and Fiat Chrysler posted mixed August U.S. sales, with GM up 7.5 percent and Ford and Fiat Chrysler down. Japanese automaker Toyota improved sales by nearly 7 percent, while Honda fell 2.4 percent. Still, analysts focused on the potential for Detroit automakers to cut inventories and stabilize used vehicle prices as residents of Houston, the fourth largest city in the United States, are forced to replace tens of thousands, perhaps hundreds of thousands, of vehicles after the devastation from Hurricane Harvey. Mark LaNeve, Ford's U.S. sales chief, told analysts on Friday that following Hurricane Katrina in 2005 "we saw a very dramatic snapback" in demand. That said, Ford sales fell 2.1 percent in August. It sold 209,897 vehicles in the United States, compared with 214,482 a year earlier. Sales were down 1.9 percent in the Ford division and off 5.8 percent at Lincoln. Demand was down for cars, crossovers and SUVs. It was not clear how many vehicles in the Houston area will be scrapped, LaNeve said, saying he had seen estimates ranging from 200,000 to 400,000 to 1 million. Ford's Houston dealers may have lost fewer than 5,000 vehicles in inventory, he said. Ford is the No. 1 automaker in the Houston market, with 18 percent share, according to IHS Markit. The company plans to ship used vehicles to Houston dealers and has "every indication we would have to add some production" of new vehicles to meet demand, LaNeve said. Investor concerns about inventories of unsold vehicles and falling used car prices have weighed on Detroit automakers' shares most of this year. Now, automakers can anticipate a jolt of demand from a big market that is a stronghold for Detroit brand trucks and SUVs. "It's got to be a positive for the industry," LaNeve said. Investors appeared to agree. GM shares rose as much as 3.3 percent to their highest since early March. Ford increased 2.8 percent at $11.34, and Fiat Chrysler's U.S.-traded shares were up 5.2 percent $15.91, hitting their highest in more than five years. GM reported a 7.5 percent increase in U.S. auto sales in August, helped by robust sales of crossovers across its four brands.

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.
