Every vehicle the Hurricane engine has been is a sales disaster. That engine on its own led to Stellantis worse sales years across every vehicle the Hurricane was in and you see now why they got rid of Tavares and put the Hemi back in vehicles and now Ram has magically recovered within 6 months of just the 5.7 Hemi back even though the trucks are still way too expensive.
Stellantis thought if they made the RHO the same price as the 2021 TRX when it first came out, they would get a sales boom. They were mistaken and even at the same price point of the 2021 Ram TRX, the RHO sales are nowhere near the TRX and the TRX production numbers were held back by covid shortages and dealer markups. I guarantee you if they made a 65k 392 Hemi V8 RHO, it would easily out sale the Hurricane RHO even with it being slower.
