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.

2015 Chrysler 300 First Drive [w/video]

When Chrysler last updated its 300 in 2011, the fullsize sedan market was a very different place than it is today. Ford's redesigned Taurus was in showrooms, sure, but segment stalwarts like the Toyota Avalon and Chevrolet Impala were languishing at the tail end of their model cycles. And still, the second-generation 300 (not counting the "letter series" cars from the 1950s and '60s, of course) failed to recapitulate the booming success of the model reboot in 2004. Something in the combination of the down economy, higher gas prices and great product from front-wheel-drive entries in the class kept the 300 from the six-digit sales numbers it saw in the early 2000s. For the 2015 model year, Chrysler hopes that a more clearly defined purpose for its big sedan, combined with liberal dipping into the corporate tech toy box, will rekindle buyer interest. Considering the mild characters and front-driver dynamics of its mainstream competition, the promise of V8 power and rear-wheel drive should at least turn the heads of those looking for a car with a little edge. I grabbed the keys of the edgiest of the bunch, the sport-intended 300S, and found a big sedan that gives away some practicality to the rest of its segment mates. The trade-off for the dip in pragmatism is an uptick and driving fun and attitude that should make all the difference for the right buyer. Even though the hard-to-miss face of the 300 has come in for another nip and tuck, that attitude is still clearly on display, too. The grille of the 300 is some 33-percent larger than the outgoing model, though it's still far less brutal than the throwback styling of the 2005 "Baby Bentley" car, at least to my eyes. The cheese grater insert is metallic in most trims of the 300, though the 300S you see in my photo set gets the meaner blacked-out treatment. A quick scroll through our gallery will show you that the rest of the 300 has been similarly changed but not reinvented. Light clusters front and rear are revised, the rear clip has been re-forged with less busy styling, and the whole car has been de-chromed to a large extent (this 300S is wearing the least blingy outfit of the bunch). That rear spoiler is S-model specific. I held the existing 300 interior in fairly high regard, and this new car improves on that base.

FCA inline-six rumored to be real, headed for Jeep Wagoneer

In September, Allpar reported that that clues being dropped at Fiat- Chrysler headquarters, in the carmaker's factories, and on engineer resumes pointed to the development of an inline six-cylinder engine. The site has just proclaimed the rumor is reality, writing that the straight-six, "turbocharged to meet or beat 5.7 Hemi power ratings, with a smoother torque curve, is on the way." The motor's first outing is expected to be either the next-generation Jeep Grand Cherokee, debuting perhaps next year, or the Jeep Wagoneer, debuting in 2020 or 2021. "Tornado" is the purported codename for the power plant said to be just under three liters in displacement, expanding the family begun with the Global Medium Engine 2.0-liter turbo codenamed Hurricane. Engine bay constraints and a long use horizon mean engineers won't simply add two more cylinders to the GME, however. Allpar says the brief is to keep the Tornado GME-T6 — the alphanumeric for "turbocharged six" — no more than three inches longer than the Tigershark 2.4-liter four-cylinder. That means "major design changes" that could include a space-saving head, more closely spaced cylinders, and no cylinder liners. An FCA division called Comau could be called on for its "SmartSpray" plasma lining technology. Allpar muses that the standard version of the engine for Chrysler, Dodge, Jeep, and Ram could get a single twin-scroll turbocharger. Performance trims for Alfa Romeo and Maserati could get different heads and maybe twin turbos, an SRT version might also get both those tweaks. History shows that the Italian versions would make changes to the block, as well. Even so, the Tornado would be less expensive than any Ferrari-supplied V6. A straight-six would put FCA in company with current adopters BMW and Mercedes-Benz, future users like Jaguar, and perhaps Aston Martin. The engine would span the widest range of use cases in the U.S. carmaker's portfolio, though. Potential applications include being a base engine for Ram trucks, serving double duty as a base engine and 5.7-liter Hemi replacement for the Dodge Charger and Challenger, working in the high-end Jeeps, and as a properly hot trim — with Ferrari-designed heads — in the luxury Italian sports cars. The Alfa Romeo Giulia begs for just such motivation to fill the gap between the 280-hp, $42,695 Ti Sport RWD and the 505-hp, $73,700 Giulia Quadrifoglio RWD. And a twin-turbo inline-six in a Maserati Alfieri would stack up nicely with the Germans.
