500+ hp Stellantis 'Hurricane' I6 previews a world without Hemis

After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged "Hurricane" I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company's North American rear-wheel-drive platforms.  What is "V8 power," exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We'll save you a little legwork: In current Ram, Jeep and Dodge products, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or take, and the 6.4-liter around 485 hp and 475 lb-ft.    This is a clean-sheet design that is only related to the company's turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid/port-injection here) and the two I6 variants share 96 common parts, including the block and oil pan design. The differences are found in their internals, intake plumbing, valvetrain components and the turbochargers themselves. Stellantis is not yet ready to share specs or supplier info for the turbos but says announcements will come from its partners soon.  The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium. The new I6's advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they're heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430 pounds, Stellantis engineers told us; the high-output adds just another 11. Fully dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters close in on 600 pounds.  You may be wondering, "Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?" A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won't be instantaneous.

2013 Jeep Wrangler Unlimited Rubicon 4X4

Ice skates are spectacular on frozen water, yet they are dreadful everyday footwear. I consider the Jeep Wrangler equally as specialized.
I recently spent a week with a 2013 Jeep Wrangler Unlimited Rubicon 4X4. Introduced for the 2007 model year, the Wrangler Unlimited is a standard JK two-door with 20.6 inches added to its wheelbase and two additional doors bolted to its passenger compartment. While Jeep offers the Unlimited in seven different trim levels, the desirable Rubicon is the most capable when the pavement ends, as it boasts a slew of hardcore off-road tools including front and rear electronic locking differentials and a front sway bar that can be disengaged at the touch of a button for improved articulation. My I-Look-Like-A-Traffic-Cone test model started with a base price of $34,095 (plus $995 destination). Options including a five-speed automatic transmission, Uconnect, tow package and a premium soft top, drove the bottom line up to $38,630.

FCA issuing software update for 1.4M vehicles to prevent hacking

In the wake of a Jeep Cherokee being hacked remotely while on the road through its Uconnect infotainment system, FCA US is now issuing a software update for 1.4 million vehicles in the United States. Affected customers will receive a USB stick in the mail with the improved version; owners can check this website to see if their cars are affected. A large variety of models with FCA's 8.4-inch touchscreen infotainment system are affected. They include the 2015 Chrysler 200, 2015 Chrysler 300, 2015 Dodge Charger, and 2015 Dodge Challenger; 2013-2015 Dodge Viper; 2013-2015 Ram 1500, 2500, and 3500; 2013-2015 Ram 3500, 4500, and 5500 chassis cab; 2014-2015 Jeep Grand Cherokee and Cherokee; and 2014-2015 Dodge Durango. According to FCA in its announcement, the new software "insulates connected vehicles from remote manipulation." As of July 23, the company also "fully tested and implemented within the cellular network" additional security to prevent access to many of a vehicle's systems. FCA US says that it's conducting this campaign out of an abundance of caution and disputes the notion that there's a defect with these vehicles. Beyond the demonstration of the hack in the Cherokee, the automaker says that it's unaware of any other reports of these attacks actually happening. Related Video: Statement: Software Update July 24, 2015 , Auburn Hills, Mich. - FCA US LLC is conducting a voluntary safety recall to update software in approximately 1,400,000 U.S. vehicles equipped with certain radios. The recall aligns with an ongoing software distribution that insulates connected vehicles from remote manipulation, which, if unauthorized, constitutes criminal action. Further, FCA US has applied network-level security measures to prevent the type of remote manipulation demonstrated in a recent media report. These measures – which required no customer or dealer actions – block remote access to certain vehicle systems and were fully tested and implemented within the cellular network on July 23, 2015. The Company is unaware of any injuries related to software exploitation, nor is it aware of any related complaints, warranty claims or accidents – independent of the media demonstration.
