With the 2017 Geneva Motor Show almost over now, it's time to focus on upcoming events and cars. More specifically, the New York Auto Show is just a few weeks away, and so is the unveiling of the incredible Dodge Challenger SRT Demon. In case you haven't figured it out yet, Dodge just launched a new teaser for the muscle car.

Called "No Pills," the latest video showcases the Demon's exhaust note as it prepares to run the quarter-mile. And needless to say, it sounds like there might be something wrong with the supercharged V-8 under the hood. But Dodge is quick to explain that the unique exhaust note is the result of an advanced torque reserve launch system specifically designed for drag racing.

So what's torque reserve? Glad you asked. According to Dodge, the system lets more air flow through the engine before launch, allowing for increased supercharger rpm without torque overwhelming the brakes and spinning the rear tires. Available when the car is used in Launch Mode only, torque mode kicks in when engine rpm is greater than 1,000.

When that happens, it closes the bypass valve on the supercharger and manages fuel flow to cylinders and changes spark timing. To balance engine rpm and torque, the powertrain controller briefly cuts fuel flow to selected cylinders, which creates the noticeable change in the exhaust tone. With torque reserve managing the engine output, the supercharged engine builds boost pressure before leaving the starting line and reaches maximum boost pressure quicker. This enables the SRT Demon to make better use of its increased contact patch drag radials and get off the line quicker and run the quarter miles faster.

Again, there's no specific data about how quick the Demon is on the drag strip, but we should find out more closer to the 2017 New York Auto Show in April. Four more teasers will be released over the next four weeks, with the fifth to effectively launch the production model. Stay tuned!
