Hennessey Dodge Demon sets hellishly fast quarter-mile time

The Dodge Demon doesn't strike us as a muscle car much in need of a performance makeover. After all, this 840-horsepower MoPar machine's voracious quest for straight-line speed means it trims weight by jettisoning everything from a front passenger seat and rear seat, to its stereo and all carpeting in the trunk. The folks at Hennessey apparently think that's not nearly extreme enough. So, the Texas-based tuning outfit has turned the Demon into a 1,035-horsepower mega beast that runs a quarter-mile in 9.14 seconds at 152 mph. That's fast, really fast. In fact, the HPE1000 is now the world's fastest Dodge Demon, having set its record-setting pace at Lonestar Motorsports Park on May 8. "The 2018 Demon is a street-legal rocket from Dodge, but we wanted to take the car's impressive track times to an industry leading level." said president and company founder, John Hennessey. For comparison, the stock Dodge Demon is credited with running the quarter-mile in 9.65 seconds at 140 mph. The main HPE1000 modification involves replacing the stock 2.7-liter supercharger with one that's a staggering 4.5-liters in capacity. Also included in the Hennessey toy-chest are stainless steel long tube headers, a high-flow air induction system, upgraded throttle body, upgraded fuel pump and fuel injectors, along with custom engine management calibration. When all is said and done, the HPE1000 Dodge Demon delivers a total of 1,035 horsepower at 6,500 rpm and 948 pound-feet of torque at 4,200 rpm. While the standard Demon accelerates from 0-60 mph in only 2.3 seconds, the Hennessey variant trims this down to only 1.9 seconds. That's quick enough to make a Bugatti Chiron blush. Hennessey hasn't stated what all this will cost, though the company did say production of these devilishly fast Demons will be limited to only 50 examples. Customers also receive a 1-year/12,000-mile warranty, which seems a nice touch for a car that's downright scary with its performance specs.

Stellantis reveals STLA Large platform with EV and ICE support

Hot on the heels of a Jeep Wagoneer S teaser and photos of the prototype next-generation Dodge Charger (or Challenger), comes a reveal and details of what will likely underpin both of them: the STLA Large platform. It's one of multiple Stellantis flexible architectures that will be the basis of its upcoming electric cars, and apparently internal combustion ones, too. Stellantis says the STLA Large platform will be for D- and E-segment cars, crossovers and SUVs. In other words, it will be for midsize and large vehicles. For reference, lengths supported will be from 187.6 to 201.8 inches, and width will range from 74.7 to 79.9 inches. It will be highly flexible, too, with Stellantis claiming significant amounts of adjustability in overhangs, wheelbase, suspension placement and powertrain arrangement. The powertrain flexibility is quite impressive. Front-, rear- and all-wheel-drive layouts will be supported. Single- and dual-motor layouts will be on offer. Internal combustion will be available, too, either on its own or as a hybrid. Apparently engines can be fitted either longitudinally or transversely, too. Battery packs with between 85 and 118 kWh of capacity will be offered, with Stellantis claiming that sedan-style vehicles could have a range of up to 500 miles. The packs will also be available in 400- and 800-volt designs. Stellantis noted also that the platform can "easily accept future energy storage technologies when they reach production readiness." This seems to hint that the company is looking at different battery chemistries and maybe even solid-state batteries that could be added more easily in the future. Furthermore, the platform is designed to handle impressive output. Stellantis says that some models on the platform will have 0-to-62 mph times in the 2-second range. Limited-slip differentials for improved power delivery and wheel-end disconnects for reduced mechanical drag are also on the table for this platform. All of these details fit well with the information previously given for the concept Dodge Charger Daytona Banshee and Jeep Wagoneer S. The former was previewed with both battery voltage architectures and a wide range of electric powertrains with between 456 and 670 horsepower depending on specification and upgrades. And that's just for the 400-volt system; the 800-volt option wasn't detailed. We've also seen photos of the Charger chassis seemingly with provisions for gas engines, likely versions of the Hurricane I6.

What does Jeep have cooking with this stretched Cherokee?

Chrysler has been spotted testing what appears to be a stretched Jeep Cherokee prototype. Which seems odd, considering that Jeep already makes a Grand Cherokee, and that's an entirely different model. The question then is just what the company has in the works here. We don't know for sure – but we do have some ideas. We're anticipating a new Grand Wagoneer to serve as the brand's flagship model, but stretching the Cherokee's wheelbase to leapfrog the Grand Cherokee's would take more than eight inches – and stretching a "compact" platform to get there wouldn't seem to make a lot of sense. Alternatively Jeep could be looking to wedge a new model into its lineup in between the Cherokee and Grand Cherokee, potentially offering a third row of seats and wearing the Wagoneer name - sans the "Grand" - as part of a new range of seven-seaters. Just what the point would be, however, when the Dodge Durango already offers three rows based on the same platform as the Grand Cherokee, is a bit of a mystery. Another possibility is that it's not a Jeep at all, but rather a Dodge. The brand is in need of a replacement for the current Journey, and we're also waiting to see what FCA does to replace the Grand Cherokee since it unveiled the Chrysler Pacifica to replace the Town and Country. More of a crossover approach could take the Cherokee's Compact US Wide (CUSW) platform as its starting point, but stretched like this prototype to offer more space. Whatever it is, we're sure this won't be the last we'll have seen of it, so watch this space. Related Video:
