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.

2014 Jeep Cherokee will keep Liberty designation in China... sort of

Chinese buyers will get their first live look at the 2014 Jeep Cherokee during the Shanghai Motor Show, but CarNewsChina is reporting that it will go by a different name - Ziyou Guan, which translates to "Liberty Light." The article states that our Jeep Liberty was never sold in China, but the iconic XJ Cherokee was sold and produced there as the Qinuoji (a phonetic translation of Cherokee).
The new Jeep Liberty Light will be built alongside the Fiat Viaggio (China's Fiat-badged version of the Dodge Dart) at the Guangzhou-Fiat plant, and the two models will share the same powertrains: a 1.4-liter turbocharged four-cylinder base engine paired to a five-speed manual or a dual-clutch transmission and a 2.4-liter four-cylinder (the base engine for the US-spec 2014 Cherokee) as an optional engine. It doesn't sound like the 3.6-liter Pentastar V6 will be offered in China.
We'll be on hand when the new Jeep debuts in Shanghai, so stay tuned to Autoblog this Friday night and Saturday for our live coverage of the show.

Jeep shows off Moab Easter Safari concepts crawling the red rocks

While most brands are busy showing off in New York, Jeep headed out to Moab for the Easter Jeep Safari with the company's fleet of 2013 concepts. This year saw the Grand Cherokee Trailhawk II, Wrangler Mopar Recon, Wrangler Stitch, Wrangler Sand Trooper II, Wrangler Flattop and Wrangler Slim Concepts tackle the rocks and sand, and Jeep was kind enough to bring along a camera crew to film the machines rolling over a few obstacles. The result is the video below, though don't expect to see too much hardcore off road action.
Instead, the quick clip features more than a few interviews with Jeep executives, including Jeep Head of Product Design Mark Allen, explaining what makes the Easter Jeep Safari so important. You can check out the quick clip below for yourself, and be sure to thumb through our galleries of the concepts as well.
