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.

Somebody created a Dodge Challenger SRT Demon droptop

The Dodge Challenger SRT Demon is a vehicle built with one purpose in mind: going fast down a drag strip. Weight is the enemy when it comes to acceleration, and one surefire way to add weight to a car is to make it into a convertible. However, that’s exactly what one Demon owner decided to do to their Challenger. Motor Authority spotted this Plum Crazy Demon convertible conversion for sale online, and the dealer and builder even spilled a few details on the car itself. This particular conversion was done by Droptop Customs, a shop with experience, having previously converted a couple Challengers into convertibles for Shaq in Miami. However, ripping the roof off the 840-horsepower Demon is no small task. ThatÂ’s a ridiculous amount of horsepower to handle for a car that has lost a fair amount of structural rigidity from removing the roof. The Droptop Customs sales manager told MA about the changes that were made to make this build work. To begin, the frame rails were reinforced with 1x2-inch pieces of metal. Then, the shop added diagonally-mounted metal braces underneath to resist twist. Even more structural supports were added to the trunk, front and rear shock towers, and gussets were added to the bottom of each door to keep them from moving. Lastly, the shop boxed the connection of the front rails to the engine cradle. No specifics about weight gain were provided. There is one sad bit of news about this Demon, though. The dealer told MA that itÂ’s currently on consignment, despite being listed for sale on FCA dealership Cape CoralÂ’s website. ItÂ’s priced at an eye-watering $145,995. But the new owner wonÂ’t have to manually put down the top! ThatÂ’s right, itÂ’s powered, and itÂ’s supposed to take about 20 seconds to lower or raise into place while stationary. Somehow, the car has only 172 miles on it, so itÂ’s hardly been used. We have no photos with the top up, so youÂ’ll have to settle for top-down photos for now. It looks like a professional job through and through, and we actually dig the convertible look. Plus, who doesnÂ’t love Plum Crazy? 

Dodge Charger Hellcat hitting 60 in 2.9 seconds on drag radials?

The Dodge boys and their cousins from SRT have shoehorned the same 707-horsepower, 6.2-liter supercharged V8 into both the Dodge Challenger and Charger. The former being a two-door, it's lighter than the latter four-door sedan. So it would stand to reason that the Dodge Challenger SRT Hellcat would be the quicker of the two, right?
Only that's not necessarily proving to be the case. On stock rubber, yes, the coupe beats the sedan: Dodge quotes a 0-60 time of 3.7 seconds for the Charger SRT Hellcat and 3.5 for the Challenger. Same gap across the quarter-mile: 11 seconds flat for the Charger versus 10.8 seconds for the Challenger. But according to recent reports, the story changes when you put both on drag radials.
While visiting Chrysler HQ in Auburn Hills, MI, TorqueNews.com caught wind of performance figures for the Charger Hellcat on drag tires: 0-60 in a mind-blowing 2.9 seconds and a quarter-mile in just 10.7. The latter figure just barely pips the Hellcat-powered Challenger's NHRA-certified figure of 10.8, making the Charger not only the fastest sedan on the market, but also the fastest muscle car. What isn't immediately clear, however, is whether the drag radials in question have any tread on them and are street-legal, or if they're pure slicks confined to a closed strip.
