Single Photo of Dodge Demon Leaks Ahead of Official Debut

Posted April 10, 2017

Should the octane level drop while on the move, a message in the instrument cluster tells the driver the vehicle will use regular until the engine is shut off and restarted.

One week out from it's debut and the Dodge Challenger SRT Demon is still teasing us.

It concerns the car's fuel system. With a massive supercharger, a torque converter and more power than the Hellcat, there's no way the SRT Demon gets decent fuel economy, even if it is 200 pounds lighter than its predecessor and has removable back seats. This high octane fuel will be available at selected places. " There, owners will find a special powertrain control module that allows the engine to run on the higher-octane fuel".

Engine knock, also known as pinging, is a sort of rattling sound made when extra pockets of air-fuel ignite within an engine cylinder.

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. It won't move to the more aggressive timing unless the knock sensors detect a proper amount of race gas.

The answer is: premium unleaded (91 octane) pump gas or 100-plus-octane racing fuel.

To prepare the Demon to utilize this high-octane fuel variety, drivers will have to use separately-shipped Direct Connection Performance parts.

The 2018 Dodge Challenger SRT Demon will be the first auto made by company that will have the design that will be feasible for both track and road.
