Hennessey H1000 ‘Last Stand’ Dodge Challenger & Charger, 2023. The final run of the supercharged 6.2-litre Hellcat HEMI V8 is marked with an upgraded version of the engine that produces 1000hp thanks to larger supercharger (non-Redeye models only), upgraded fuel injectors, a high-flow induction system, pulley upgrade, stainless-steel long tube headers, high-flow catalytic converters, and a crankcase ventilation system.
