As R&T first reported back in July, rumors have swirled that Dodge is planning to unveil a variant of the Challenger capable of running on E85 fuel. This model was rumored to bring as much as 909 hp to the table, which is 202 more than the original 6.2-liter Hellcat engine provided when it arrived in 2015. In fact, that’s quite a bit more power than provided by the Dodge Demon, which makes just 840 hp when running on race fuel. Those sorts of power levels could explain why Dodge is currently struggling with reliability as far as the final Last Call model is concerned. Dodge requires all of its production engines to survive extensive dyno testing, during which time the engines may be run at full tilt for hundreds of hours.
