Dodge Challenger Demon Will Run on Both High-Octane and Premium Fuel
Run the quarter-mile on high-octane at the flick of switch!by Ciprian Florea, on
Set to be unveiled on April 11 at the 2017 New York Auto Show, the highly anticipated Dodge Challenger SRT Demon is less than a week away from breaking cover. And, Dodge is making sure the hype is as big as possible with a brand-new teaser video and a final release set for tomorrow. Today’s video is called "Fuel" and focuses on the car’s ground-breaking fuel system.
Essentially the first factory production car able to run on either 100+ high-octane unleaded fuel or the more common 91-octane fuel, the Challenger Demon can be set up for optimum performance on either public roads or the race track at the flick of a switch. Specifically, Dodge created a special powertrain control module calibrated for high-octane fuel and placed a new switch bank on the center stack for easy access. The car leaves the factory with the control module set for premium unleaded pump gasoline, but once at the track, the driver can easily switch to high-octane.
When activated, the controller enables the supercharged Hemi engine "to extract the maximum power from the knock-resistant high-octane fuel by optimizing spark timing," and return "big changes in elapsed time." Dodge says that mixing high-octane and premium unleaded fuels in the tank won’t hurt the Demon’s engine, but it turns out that the high-octane function won’t activate if the combined fuel octane is too low. Drivers will be able to check the octane in the gauge display thanks to a controller that monitors the engine’s knock sensors. On top of the dual fuel pump, the SRT Demon will also feature larger fuel injectors and higher rail pressure.
Needless to say, the Demon is indeed the kind of car you can drive to the drag strip, run the quarter mile, and then return home with minor modifications.
