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.

2020 Ford Explorer ST vs 2019 Dodge Durango SRT: How they compare on paper

For a few years now, the Dodge Durango SRT has been the sole three-row performance crossover from a non-luxury brand. That all changes now that the 2020 Ford Explorer ST is coming to market. Now we have two family crossovers with rear-drive-based platforms vying for buyers that demand practicality and power. As such, there's no better time to dig into their specs to see how they compare. We'll check out each crossover's horsepower, torque, space, capability and prices. The full specs are listed below, followed by some analysis afterward. We also compared the regular 2020 Explorer models to other crossovers in this segment, if if that's not enough, you can check out our car comparison tool. Performance The Explorer and Durango go about making power in very different ways. The Explorer goes the force-fed route with two turbos feeding a 3.0-liter V6, while the Durango's enormous 6.4-liter V8 produces power with air flow au natural. Of the two, the Durango has the greater output of 475 ponies and 470 pound-feet of torque, feeding the flames of everyone that lives by the phrase "There's no replacement for displacement." The Explorer is no slouch at 400 horsepower and 415 pound-feet of torque, though. Performance isn't purely based on power, though. Other factors play a role, such as weight, and in that regard, the Explorer is way ahead. At 4,701 pounds, it weighs a massive 809 pounds less than the portly Durango. This also means that both crossovers are very close in weight-to-power ratio, with the Explorer only slightly worse at 11.75 pounds per horsepower and the Durango at 11.6. Less weight will also play a roll in handling, and the Explorer is likely to feel sprightlier without so much mass to shift back and forth. Semi-related to handling are tire sizes. The Durango features 295-mm wide tires on 20-inch wheels. The Explorer has 255-mm wide tires on 20-inch wheels, but 21-inch wheels with 275-mm tires are available. So the Durango is working with more contact patch, but as we mentioned, it's carrying a lot more weight. 2020 Ford Explorer ST View 20 Photos Interior Space and Practicality Although the Durango SRT is the largest on the outside in every dimension, it loses out to Explorer repeatedly inside. The Ford has more headroom, leg room and shoulder room in nearly every row except the third-row where headroom comes up a bit short.
