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.

We're pretty sure the Challenger SRT Demon won't have 1,121 horsepower, but what if?

Dodge's slow rollout of the upcoming Demon continues, and with it comes endless speculation about what it all means. Every video, every image, and every press release contains some clue that points towards the Demon's final specs. We don't think any of it is random or arbitrary. This week cryptic image, a small plate with a name and two numbers, shows us a little more than last week's license plate. Unfortunately, Dodge will neither confirm or deny anything, meaning we have no way of knowing which rabbit hole to go down. Don't expect to see official horsepower, a quarter-mile time, or an MSRP until the New York Auto Show. The plate is attached to the crate of goodies that comes along with every Dodge Demon. This particular one is labeled with three things: Tom Coddington, serial number 0757, and VIN 001121. The name is simple enough. According to Hot Rod, Coddington was one of the original Ramchargers, a group of engineers in the early 1960s that helped Dodge get involved in drag racing. He was a fuel system specialist, motor consultant, and a rotating garage manager. All of that could be clues. While a name is easy enough to Google, the two numbers can't be broken down so easily. The crazier theory is that the car makes 1,121 horsepower and will do the quarter-mile in 7.57 seconds. Frankly, those numbers are about as likely as the Demon actually being powered by a Rolls-Royce turbofan engine from a Boeing 757 or packing a carburetor with 1,121 CFM. The Demon is going to be street legal, and the costs associated with making a 1,121-hp car meet emissions standards alone are assuredly astronomical. As our friends from Road & Track pointed out, the more likely theory is that 757 is actually the horsepower rating. This seems totally plausible, but it means we still don't know what 1,121 means. Surely it's not a drag strip time, as the standard Hellcat will do 1/4 mile in 11.2 seconds. Like before, if you have any ideas, post them in the comments. Until April, we'll keep trying to solve Dodge's demonic puzzle. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

The Dodge Demon's massive torque wrinkles its massive tires

Horsepower doesn't mean a damn thing if a car can't properly put the power down. That's why Dodge has fitted the upcoming Demon with some of the stickiest road-legal rubber available. Those Demon-branded Nitto NT05R drag radials skirt by regulations with just the smallest of margins, and in order to maximize the potential of the 315/40R 18 size tires Dodge increased the car's torque multiplication with a higher stall speed for the torque converter and a 3.09 rear axle. The 12.6-inch-wide tires are fitted to 18x11-inch wheels at all four corners, and they're fatter than those 305-section front tires on the Camaro Z/28 that we raved about years ago. Dodge says the combination of soft, gooey rubber and the new gear ratio gives the Demon about a 15 percent larger tire contact patch, more than twice as much grip, and roughly an 18 percent increase in both converter torque and rear-axle torque multiplication. Simply put, the Dodge Demon moves. You can see the results in the teaser video above, which is titles "Multiplication" and shows the crazy wrinkling of the sidewall that results from putting that torque to the road. We wouldn't be surprised if the inner rim of the wheel needs some grip to keep the tire seated, something Chevy had to do on the last Z/28. There is something wonderful about Dodge's approach to performance cars. While the Ford Mustang and Chevrolet Camaro have moved on from their muscle car upbringings with proper track-focused models, Dodge has stayed true to its roots by developing a machine that's sole intent is traveling a quarter-mile quicker than anything else on the road. Twisty roads may be fun, but there is something wholly and deeply satisfying about going deep into the accelerator with a comical amount of power at your disposal. We can't wait.
