The Last 2018 Dodge Challenger SRT Demon Teaser May Give You Gas

2018 Dodge Challenger SRT Demon Reveals Its Drinking Habits [Video]

Dodge Challenger Demon will have special mode for race fuel

M - For those who'll want to squeeze the last drop of power out of the 2018 Dodge Challenger SRT Demon's supercharged 6.2-liter Hemi V-8, word comes today with the 13th teaser video that the vehicle - debuting at an event ahead of the 2017 New York International Auto Show - will come with a factory tune for 100-plus octane racing gas.

It concerns the car's fuel system. They're included in the Demon's crate of go-fast goodies. This in turn will create more impressive elapsed times for drag racers behind the wheel of the Dodge Demon.

The keys to unleashing the SRT Demon's full fury are in the Demon Crate shipped separate: Direct Connection Performance parts that include a new powertrain control module (PCM) calibrated for the high-octane fuel and a new switch bank for the center stack that includes a high octane button.

Mixing high-octane and regular fuel in the tank won't hurt the Demon's supercharged 6.2-liter V-8, but the high-octane function won't activate if the combined fuel octane is too low. Igniting the spark plugs earlier (aka retarding the spark timing) reduces power output, but it can prevent knock from consuming an engine.

However, we will know the answer to all of our questions when the vehicle is released on April 11. Once equipped, the Demon can switch between maps that are optimized for either 91 octane pump gas and 100+ octane unleaded race gas.

Look for the Dodge Demon to finally make its debut on April 11 before AutoGuide.com checks it out up close at the 2017 New York Auto Show. The controller monitors the engine's knock sensors.

A bonus video will be released tomorrow before Dodge reveals the Demon on Tuesday, April 11.
