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.

Nine cars we wish were convertibles

The snow has melted, the sun is shining, and the days are getting longer. At the Autoblog Detroit office we feel like our winter hibernation is finally over. And with warmer temperatures come visions of opening up a convertible roof and cruising. You know, just turn up the bass and let the Alpine blast. There are plenty of droptops on sale in the US, and more on the way (like the 2016 Mazda MX-5 Miata). That said, we always want more. More! More! More! In that spirit, we cooked up a list of nine cars aren't currently sold as convertible, but ought to be. Check out our picks, below. Summer's just around the corner. Subaru BRZ / Scion FR-S In some parallel universe, this car actually happened. Toyota showed us a FT 86 Convertible concept at the Geneva Motor Show in 2013, and we immediately started licking our chops over the thought of a rear-wheel-drive convertible based on the Subaru BRZ and Scion FR-S twins. These days, the MX-5 Miata is our only option for affordable roadster fun. A competitor to the Mazda seems like a no-brainer to us, especially since we have naught but good to say about the BRZ/FR-S as-is. Unfortunately in our present timeline, this car is as likely for production as a BRZ STI. Which is to say, not very. Dang. Lexus RC F Unlike the FR-S, a convertible from Toyota's luxury division might actually see the light of day. The current IS convertible is about to be phased out, and the Lexus LF-C2 concept from the 2014 Los Angeles Auto Show is really a thinly veiled look at a possible RC convertible. A droptop RC would be plenty good, but let's reach for the starts. What we really want is to run topless in an RC F, complete with that powerful, loud, 5.0-liter V8 engine. Lexus says the RC F is a true competitor to the BMW M4. If that's true, it only makes sense for Lexus to mimic the Germans and offer its performance coupe in a folding hardtop form. Maybach Landaulet Maybach is bach back, recast as an upper crust trim level for Mercedes-Benz. The Mercedes-Maybach S600 is seriously awesome, and more luxurious than a trip to the spa. But why not go a step into the truly ridiculous levels of extravagence and bring back that open-top Landaulet? We think your local princess will love this idea, and with better S-Class bones underneath, Jeeves will have a pretty enjoyable ship to steer, too. Besides, with that slick new Mercedes design language, a Landaulet redux wouldn't be nearly as hideous as the old model, pictured here.

The Chrysler brand could be axed under Stellantis management

MILAN — While running NissanÂ’s North American operations from 2009 to 2011, Carlos Tavares had a reputation for closely watching costs with little tolerance for vehicles or ventures that didnÂ’t make money. Experts say that means Tavares, currently the head of PSA Group, is likely to follow that blueprint when he becomes leader of a merged PSA and Fiat Chrysler Automobiles. The low-performing Chrysler brand might get the axe as could slow-selling cars, SUVs or trucks that lack potential. Already the companies are talking about consolidating vehicle platforms — the underpinnings and powertrains — to save billions in engineering and manufacturing costs. That could mean job losses in Italy, Germany and Michigan as PSA Peugeot technology is integrated into North American and Italian vehicles. “You canÂ’t be cost efficient if you keep the entire scale of both companies,” said Karl Brauer, executive analyst for the iSeeCars.com auto website. “WeÂ’ve seen this show before, and weÂ’re going to see it again where they economize these platforms across continents, across multiple markets.” Shareholders of both companies are to meet Monday to vote on the merger to form the worldÂ’s fourth-largest automaker, to be called Stellantis. The deal received EU regulatory approval just before Christmas. Tavares, who for years has wanted to sell PSA vehicles in the U.S., wonÂ’t take full control of the merged companies until the end of January at the earliest. He likely will target Europe for consolidation first, because thatÂ’s where Fiat vehicles overlap extensively with PSAÂ’s, said IHS Markit Principal Auto Analyst Stephanie Brinley. Europe has been a money-loser for FCA, and factories in Italy are operating way below capacity — a concern for unions, given FiatÂ’s role as the largest private sector employer in the country. “We are at a crossroads,Â’Â’ said Michele De Palma of the FIOM CGIL metalworkersÂ’ union. “Either there is a relaunch, or there is a slow agonizing closure of industry, in particular the auto industry, in Italy.” ItalyÂ’s hopes lie with the luxury Maserati and sporty Alfa Romeo brands, but De Palma said investments are needed to bring hybrid and electric technology up to speed. FiatÂ’s Italian capacity stands at 1.5 million vehicles, but only a few hundred thousand are being produced each year. Most factories were on rolling short-term layoffs due to lack of demand, even before the pandemic.
