In place of the Hemi V8, a GME T6 (Global Medium Engine Turbocharged 6) would be used. The next-gen Challenger supposedly features a straight-six turbocharged twin-turbo that can compete with Hemi in terms of output. An ex-Stellantis worker has confirmed to Mopar Insider that the next-gen Charger and Challenger will be powered by a new 3.0-liter, twin-turbocharged inline-six.
Another piece of information is that Dodge will keep selling the Charger and the Challenger with a new straight-six twin-turbo engine. The report indicates that the next-generation Dodge muscle cars will offer the twin-turbo V6 as the top-of-the-line engine option, rather of the Hemi engine that now makes the Challenger and Charger the most powerful cars in their classes. Using the twin-turbo straight-sixes as the transition between the gas-powered era and the electric era, the Hurricane engine may replace the Hemis featured in the current Charger and Challenger, or a newer, modified version may arrive.
Dodge officials have stated on the record that there may be some crossover between the current Ice-powered Challenger and Charger, and the Charger and Challenger replacements, despite the fact that Hellcats will be phased out by the end of 2023. Dodge has stated that manufacture of the existing Challenger and Charger would stop in December 2023, and that the V8-powered muscle vehicles will be replaced by a new electric vehicle platform at that time. Stellantis, Dodge’s parent company, has spent a great deal of time and money developing a new inline-6 engine series called Hurricane I6 that will outperform the venerable Hemi V8s that have long been the backbone of the Charger and Challenger’s popularity.
