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.

Fiat 500X poised for Paris catwalk

We've known for some time that the new, Fiat-based baby Jeep (which may or may not be called the Jeepster) is set to arrive at the 2014 Geneva Motor Show. What we weren't sure of was whether its platform mate, the so-called Fiat 500X, would be doing so alongside or at a later date. Well, according to Reuters, we'll get to see the first all-wheel-drive 500 later this year in the City of Lights.
Yes, we can expect the 500X to arrive at the 2014 Paris Motor Show, according to an official with an Italian trade union. The unnamed source cited retooling at Fiat's Melfi factory, in southern Italy, which currently produces the Grande Punto. It's expected that the newest member of the growing 500 family will replace the Suzuki SX4-based Fiat Sedici, although when the X will go on sale remains an open question.
According to Reuters, both the Jeepster and 500X will be built alongside each other in Italy. Whether the 500X will cross the pond with it's slat-grilled cousin, though, remains to be seen (we're leaning towards yes).

Jeep Wrangler JK's exit interview: brilliant, flaws and all

The engineers at Fiat Chrysler Automobiles, Jeep's current steward (and there have been many), have to be sweating bullets as they ready the forthcoming, long-overdue replacement for the Wrangler. It's the brand's icon, its most recognizable vehicle, and the reason Jeep enjoys such success today. Most brands use their flagships to lure shoppers who will then take home a more practical, pedestrian model. Think about the relationship between Corvettes and Malibus in the Chevy showroom. For Jeep, however, the Wrangler is a business unto itself: Nearly one in four Jeeps sold new last year was a Wrangler. That's a lot of pressure as Jeep gears up to replace the current model, codenamed JK, which has been on the road since 2007. I took a Wrangler into the woods to ponder it all. The Wrangler lineup starts around $26,000 but climbs rapidly from there. At the upper end of the spectrum sits the Rubicon Hard Rock, which builds on the already capable Rubicon's locking differentials and electronic front sway bar disconnect with a host of styling goodies. At $43,325 as tested, the Hard Rock is no cheap trail toy. Wranglers have gotten more comfortable and capable over the years, but driving one is still an exercise in compromises. Luxury here means durable leather upholstery and a lot of bass from the stereo. The driving experience is of the "well, it's better than it used to be" variety on pavement. The rational buy in this segment is the Toyota 4Runner Trail, which goes off-road almost as well as the Jeep and does everything else way better. But nobody takes home a Wrangler because it makes sense. It's a middle finger extended in the direction of conformity while fording the river of beige Corollas between home and office. You don't need a Wrangler, but you probably want one. That's why Jeep sold more than twice as many Wranglers as Toyota did 4Runners last year – and the 4Runner sells well. Wrangler sales aren't slipping, but increasingly stringent emissions and safety standards are signs of the inevitable forward march of progress – and so Wrangler must change with the times. Simple ways to improve the Wrangler are obvious: An updated interior with a modern infotainment system, user-selectable traction control modes tailored to specific terrain conditions, an eight-speed automatic, better aerodynamics, and a lot of weight-saving aluminum are inevitable.
