Dodge Challenger Demon Has Advanced Torque Reserve System


Are you excited yet for the 2018 Dodge Challenger SRT Demon that’ll be revealed at the 2017 New York International Auto Show? Well maybe this video showing the car launch down the drag strip will be enough to get you fired up?

The Demon has a bit of a unique sound, especially when launch control is activated. At engine RPMs over 1,000, the torque reserve system activates allowing even more airflow into the supercharger but not causing the rear tires to break traction.

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

The more we learn about the Demon the more we’re impressed and excited about the technology implemented to make the car dominate at the drag strip. It’s like going to an aftermarket catalog and ordering everything, but it’s already on the car when you buy it from the factory.

Plus, it still should retain some daily-driver capability.

Be sure to check out everything we know about the all-new 2018 Dodge Challenger Demon and stay tuned for our coverage of the 2017 New York Auto Show!
