A look at the Dodge Demon's drag settings, modes, and go-fast tech

In the same video that gave us a peek at the 2018 Dodge Challenger SRT Demon's performance stats, there's a serious dump of info on the tech and tools that will likely help this muscle coupe slaughter drag strips. Dodge has outlined a few of them for us and we're using the power of inference to figure out the rest. Here's what we've gathered. A lot of these hints come from the Demon's version of Performance Pages, the infotainment screens that show what SRT models are doing and let the driver change the powertrain and chassis setup. There are a lot of Demon-only features, including line lock, a quick cooldown mode for the supercharged engine, and data recording. And of course there are pages to show a digital time slip with acceleration and braking figures, a g-load plot, and lots of gauges to track temps and levels. The engine output is shown in the video on a special Dyno page. It tracks horsepower and torque over time on the upper graph, and engine rpm and shift points on the lower graph. And we think it's still hiding something. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Any good drag car has a line lock, allowing the driver to lock the front brakes and leave the rears free to do a nice tire-warming (or tire-shredding, depending on length) burnout. Ford has it on the Mustang, Chevy puts it on the ZL1, and now Dodge is adding it to the Demon. It should help get the giant Nitto tires up to temp for a drag run. And once the tires are warm, there's launch control, just like on the SRT Hellcat, with selectable rpm to dial things in for the conditions. The Demon also has a shift light in the cluster, and the driver can set a shift point individually for each gear. After each drag run, you can activate Quick Cooldown, which Dodge says uses the first production application of After-Run Chiller – it runs the cooling fan and intercooler coolant pump with the engine off until the coolant reaches its target temp. It's shown in one of the slides above. The checklist on the left side of that page suggests it requires a set of conditions be met to work: engine off, hood open, and sufficient battery level. This further reinforces our theory that the supercharger is going to make big boost, beyond the Hellcat's 11.6 psi. And while you're waiting for the supercharger to cool off for another run, you can review the performance data the car records.

This Dodge Challenger was stolen, used in police chases and recovered all in the week before its SEMA debut

Most of the drama in a SEMA build is in getting the car ready in time for the big show. That was all Quintin Bros Auto and Performance was expecting when they built a supercharged Dodge Challenger Scat Pack with custom carbon fiber body parts, aftermarket wheels and upgraded brakes. But unfortunately, a bigger drama happened in the week leading up to the show. And it was the worst kind. As part owner Pete Quintin told us, the car was shipped out in a small trailer, and while the delivery driver was spending the Monday night a week before the show at a hotel, a thief showed up in a stolen pickup and made off with the trailer and the car. It wasn't an easy task, either, as the delivery driver had parked the trailer in with the truck blocking it. The thief used his own (well, not his own, but you know what we mean) truck to shove the trailer hitch out where he could access it, then hooked it up and took off. Several miles down the road, he parked, opened up the trailer and vanished in the Challenger. The following morning, the delivery driver discovered the theft, and Quintin Bros immediately informed the owner so that a police report could be filed and a search could begin. The trailer was found not too long after, thanks to someone who was following the story on social media. But obviously the car was missing. Folks on social media were also helpful in tracking the car, in addition to the help of the Las Vegas Police Department (LVPD). What followed was a week of chasing the car down. Twice the car was found in parking garages, Quintin said, and both discoveries resulted in police chases. The second chase was the most dramatic, with a police officer stopping after noticing the car. The thief was in it, and he bolted upon seeing the officer. He powered the Challenger right through the nose of the police car, damaging both. The chase culminated on the highway, where Quintin told us 14 cars were in pursuit, and the thief got up to 150 mph. Police ended up calling off the chase because of the danger. But the car was damaged enough that the thief eventually abandoned it at one last garage, where it was picked up on Thursday. Once the car was recovered, things gradually began looking up for the Quintin family. Pete Quintin said that as soon as LVPD found out the Challenger was meant to go to SEMA, the department got the car out of evidence impound as fast as it could so the shop could show off the beat-up car.

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.
