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: Introduction

When we look back at some of the more shocking product launches of recent yeras, the Jeep Cherokee is certainly high up on the list. And we aren't just talking about its off-the-wall, polarizing design.
For starters, it brought back the iconic Cherokee nameplate - something Jeep enthusiasts have coveted for ages. But beyond that, it brought a new evolution for the Jeep brand. After all, the Cherokee is car-based - using the same compact platform that underpins the Dodge Dart and Chrysler 200. It has a greater focus on technology and refinement than ever before, in an effort to appeal to a new crop of Jeep customers. And powering it all is a new (optional) V6 engine paired with an equally new nine-speed automatic transmission.
Can the Cherokee's car-based roots still allow for a vehicle that's superb when the going gets tough? Will its design still be a love/hate affair in one year's time, or will it start to blend in? Is the powertrain strong enough to not only support the needs of daily driving and road trips, but blaze a few trails as well? We're aiming to answer all these questions, and more, over the next 12 months. Welcome to the Autoblog long-term garage, Cherokee.
