Dodge Demon to Run on Racing Gas

CARS.COM — 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 car — 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.

You’ll have to do a little work on the car to get the benefit, and the highest horsepower, though just how many more horses the Demon will produce over the Dodge Challenger Hellcat’s 707 has not been revealed.

We learned earlier that buyers will be shipped a tool crate full of tools and Mopar parts to ready their drag-optimized Demon on race day. We learned today that among the gear will be a separate engine computer that can be swapped out on race day. This powertrain control module will advance the engine timing to take full advantage of the high-octane fuel, which is available at tracks (and also at certain gas stations in most areas). The Demon will be delivered with a module tuned for more typical 91-octane premium gasoline.

In addition to the extra powertrain control module, the crate also contains a new switch bank for the center dashboard controls that includes a “high octane” button. Dodge says you can mix gas with different octane levels in the tank, but the function won’t activate if the sensor detects the combined octane is too low.

The car will be fully revealed April 11. And in case you think Dodge hasn’t had enough video teasers leading up to the event, the brand says there will be final video snippet tomorrow. We’ll have it here, so check back.
