As of the time of this writing, Dodge hasn't made any official remarks on the 909-hp E85-powered Challenger rumour.

But if Dodge is developing a super-powerful last-chance Challenger, is 909 horsepower really feasible on E85? Yes, technically.

The resistance to knocking, also known as ping, increases with gasoline octane.

Due to the high component stress placed on forced-induction engines, this is essential for producing significant horsepower.

A tuner may increase boost pressure, alter the ignition timing, and improve horsepower by using a higher-octane gasoline.

Additionally, E85 produces less heat during burning, similar to methanol. As a consequence, the engine maintains a lower temperature, which also aids in increasing power.
