Dodge Challenger SRT Demon: Everything We Think We Know
Dodge has been teasing a widebody, even-higher-performance version of the Challenger Hellcat. Here’s every detail we know so far.
The day after all the motor journalists left the 2017 North American International Auto Show in Detroit, Dodge dropped a delicious little tidbit on the internet. It was a brand-new pop-up website—ifyouknowyouknow.com—leading to a teaser video hinting at something high performance and evil: The 2018 Dodge Challenger SRT Demon.
UPDATE, APRIL 11TH: It’s here! We’ve got all the specs and info live from Dodge’s official unveiling of the SRT Demon. Read all about it right here!
Since then, Dodge has released one tidbit, and one teaser video, every week, revealing tasty details about the drag-racing-optimized Challenger. Each week when that happens, we’ll update this post with the latest, all leading up to the official debut of the Dodge Challenger SRT Demon in April at the New York International Auto Show.
This Week’s News, April 6:
Yep, it’s official! The Demon gets a dedicated High Octane mode to take advantage of 100+ octane unleaded race gas. Dodge says running race fuel—available at most drag strips—will lead to “big changes in elapsed time.” The updated Powertrain Control Module (PCM) with the 100+ octane tuning comes in the Demon Crate of performance goodies.

Last Week’s News, March 30:
In a forced-induction vehicle like the supercharged Dodge Challenger SRT Demon, controlling the intake air temperature is crucial to extracting maximum performance. To accomplish this, Dodge gave the Demon a liquid-to-air charge air cooler. But that’s not all: In Drag mode, the Demon uses the air conditioning system to chill the charge air cooler. It’s a world-first feature in a production car, and Dodge says it can achieve a reduction in intake air temperature of up to 45 degrees Fahrenheit. Dodge says it’s “enough to make the engine perform like it is running in the cold Alaskan air, even after a day of runs down the strip on a hot summer day.” We figure it means you won’t have to bring giant bags of ice to put on your car’s charge air cooler and intake tract between drag runs or dyno pulls.
The News From March 23rd:
This week is all about the launch. Dodge announced that the SRT Demon will come from the factory equipped with a trans brake, a device that lets automatic-transmission drag cars explode off the line on launch. Don’t know what a trans brake is? Read all about it here.
The automaker also released this image, with a license plate that seems to hint at … something? We can’t quite figure it out. But as always, if you’ve got an idea, contact Road & Track on Facebook, Twitter or Instagram.
And check out this week’s teaser video, “Lock & Load,” at the very bottom of this page.
The News From March 16th:
Launch Mode! The Demon, of course, has it, but it’s got a little something extra in addition to the launch RPM configuration that most performance cars offer in this mode. See, when the Demon is staged at the drag strip, and revved up in anticipation of leaving the line, the system goes into torque reserve, closing the bypass on the supercharger and altering fuel and spark to the engine. This acts as a rev limiter, keeping the engine spinning at the desired RPM for best launch, but it also spools up the supercharger to build maximum boost pressure for a vigorous launch. It’s the first time such a system has been used on a production vehicle, and Dodge promises us it’ll sound wicked. You can hear the Demon’s launch mode in the video at the bottom of the page, or download the sound at IfYouKnowYouKnow.com as a ringtone.
Dodge also released yet another cryptic “secret code” license plate image this week. If you think you know what it means, contact Road & Track on Facebook, Twitter or Instagram.
