Dodge switched to electric power steering (EPS) on the Challenger Hellcat with the introduction of the 2018 Widebody Challenger Models, which require EPS due to the larger tires and wheels. In contrast, some Charger Hellcat models, especially from 2019 and earlier, retained hydraulic steering, though all 2020+ Charger models, including widebodies, use EPS(Electronic Power Steering).
