Here it is, the 13th video for the upcoming 2018 Dodge Challenger SRT Demon and it’s all about fuel.
Why fuel? Because Dodge has announced today that the Demon will be the first factory production car that can run on either 100+ high-octane unleaded fuel or 91-octane unleaded fuel…on demand. How is this possible? Here’s how according to Dodge:
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.
The SRT Demon leaves the factory with a PCM configured for premium unleaded pump gasoline, which delivers top level performance.
The switch to the Direct Connection controller enables the supercharged HEMI engine to extract the maximum power from the knock-resistant high-octane fuel by optimizing spark timing. Drag racers will see big changes in elapsed time (ET) with the high-octane fuel.
Wait a second, what if you happen to combine different octane fuels? Dodge says not to worry, as the mixture won’t hurt the engine. However, they do go on to say that the high-octane function won’t work if the combined fuel octane is too low. What’s even more interesting is that the car will display a message in the gauges that lets the driver know what fuel calibration it will be using until the engine is shut off. This information is gathered through the knock sensors.
And, as a quick side note, the Demon will have two fuel pumps, unlike the Hellcat that only has one.
