March 16, 2017 , Auburn Hills, Mich. - The new 2018 Dodge Challenger SRT Demon’s distinctive “staged” exhaust note is the focus of the newest teaser video, “No Pills,” unveiled March 16 at
This week’s release couldn’t be more fitting of Dodge’s “If you know, you know” tagline, because “if you know” you will hear extreme performance, but those who don’t will think something is wrong with the engine. Fans can hear for themselves by downloading a ringtone of the Demon’s exhaust note directly from or from Apple iTunes.
The 2018 Dodge Challenger SRT Demon’s unique exhaust note is the result of an advanced torque reserve launch system – the first ever designed for a drag race application on a production car.
What is torque reserve? In plain English, it lets more air flow through the engine before launch, allowing for increased supercharger rpm without torque overwhelming the brakes and spinning the rear tires.  
In the Challenger SRT Demon, torque reserve kicks in when Launch Mode is active and engine rpm is greater than 1,000.
Torque reserve does two things:
  • It closes the bypass valve on the supercharger, “prefilling” the supercharger
  • It manages fuel flow to cylinders and changes spark timing. To balance engine rpm and torque, the Challenger SRT Demon’s powertrain controller will briefly cut fuel flow to selected cylinders. This creates the noticeable change in the exhaust tone. The controller also advances or retards the ignition timing to fine-tune the engine rpm/torque balance
With torque reserve managing the engine output, the supercharged HEMI® engine can build boost pressure before leaving the starting line and reach maximum boost pressure quicker, taking full advantage of the SRT Demon’s increased weight transfer and increased contact patch drag radials to reduce 60-foot times.
Fans should visit to watch “No Pills” and the other 2018 Dodge Challenger SRT Demon videos. Remember, nothing is a coincidence and everything means something.
