I'd argue sticking with the turbo hybrids in 2026 is the outcome of a sunk cost fallacy: FIA have already acknowledged the complexity has been unsustainable by dropping the MGU-H; Red Bull successfully campaigned for the engine freeze just so they could get RBPT set up for 2026; Renault have been totally unable to catch up even taking full advantage of the reliability loophole and moving to split-turbo. Surely dropping turbos and electric propulsion would save more than going back to more cylinders would cost.
