The Dodge Demon Can Switch To High-Octane Race Fuel On Demand

Apr. 07, 2017 3:00 PM ET by Martin Bigg Muscle Cars / 12 Comments Of course a car as high-octane as the Dodge Demon can run on race-ready high-octane fuel. We're now only days away from the full reveal of the hellacious Dodge Challenger SRT Demon at the New York Auto Show on April 11, but Dodge still isn't done feeding us scraps of information about the demented muscle car in its three-month long teaser campaign. As we're always reminded, the Demon is designed to dominate both the drag strip and the road. With that in mind, you'll be able to switch between race-ready 100+ high-octane fuel and 91-octane pump gas on demand, in yet another first for a factory production car. Dodge assures us that mixing the two fuel types won't harm the Demon's beastly engine, but the high-octane function won't work if the combined fuel octane is too low. Drivers will be told that the car will use the premium fuel calibration via a gauge display until the engine is shut off and restarted, thanks to a controller which monitors the engine's knock sensors. There's a catch, though. If you were assuming the high-octane fuel calibration would be a standard feature, you thought wrong. Access is instead granted by fitting performance parts found in the Demon Crate, including a new powertrain control module calibrated for the high-octane fuel and a new switch bank for the center stack. Pressing the high-octane button on the center stack will allow you to switch between road and race fuel on demand - you just have to fit it yourself. Available at select gas stations, speciality shops and drag strips, running the Demon on high-octane fuel will see "big changes in elapsed time" on the drag strip, though Dodge hasn't delved into any specifics, unsurprisingly. Switching to the Direct Connection controller will let the engine extract the maximum power from the high-octane fuel by optimizing spark timing. As standard, the Demon will leave the factory with a PCM configured for premium unleaded pump gasoline, though. After 13 consecutive teasers, there's still one last missing piece of the puzzle: how much power will the Dodge Demon produce? Rumors suggest it will only produce 757-horsepower, which isn't a very substantial upgrade over the 707-hp you get in the Hellcat. We would be happy with 909-hp, but the recent reveal of the 1,000-hp Camaro ZL1 Exorcist could also spell trouble for the Demon.
