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.

Detroit automakers observing 8:46 of silence to mark Juneteenth

GM Executive Vice President of Global Manufacturing Gerald Johnson, right, talks with employees at the Fairfax Assembly & Stamping Plant in Kansas City, Kansas. (file photo - GM)     All three Detroit automakers are observing Juneteenth, a day commemorating the end of slavery, on Friday by observing 8 minutes and 46 seconds of silence, among other companywide efforts to advance the causes of social and racial justice and equality. Juneteenth marks the date, June 19, in 1865 when Union soldiers, led by Maj. Gen. Gordon Granger, arrived at Galveston, Texas, and announced the Civil War had ended and enslaved African Americans were to be freed. President Abraham Lincoln had officially ended slavery more than two years prior via the Emancipation Proclamation, but Union forces didn't reach Texas until that time, so there was virtually no enforcement. The 8:46 timestamp is significant because it was the length of time that a police officer in Minneapolis knelt on the neck of George Floyd during an arrest, ultimately killing him and sparking waves of protests across the U.S. and overseas. Autoblog asked automakers about their plans to mark Juneteenth, what they were doing to advance the cause of social justice for Black people, and how many African Americans they employ in both blue- and white-collar jobs. We heard back from GM, Ford, Fiat Chrysler and Honda but not from Nissan and Toyota. General Motors GM’s U.S. workforce is 17.2% Black and 69.2% white, according to its most recent corporate Diversity and Inclusion Report. GM's total global employment is 173,000, and it says women and minorities represent 40% of its team of corporate officers. For reference, the Census Bureau says African Americans make up 13.4% of the U.S. population of roughly 328 million people. White people constitute 76.5%. As previously reported, GM planned to pause production at its factories on each shift today and observe silence for 8 minutes and 46 seconds. The company will also have a digital countdown clock atop the GM's headquarters in Detroit for the moment of silence. Additionally, Chairman and CEO Mary Barra has said she will lead a new Inclusion Advisory Board made up of people from within and outside GM to suggest areas for change and hold the company to its commitments to fight injustice and racial inequality.

Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:
