In a traditional IC car when driving through water such as a flooded road or a ford the recommendation is to keep the revs up by using more throttle than is necessary. This ensures that the exhaust gas flow prevents water entering the exhaust pipe and prevents damage to the catalytic converter and even engine.
In a hybrid car increased throttle does not ensure that the IC engine will be producing lots of exhaust, or even be on. Is there a recommended way to prevent water entering the exhaust pipe in such a car?
Actually this is a theoretical question that occured to me. It was prompted by experiences I was told about relating to a Mitsubishi Outlander PHEV (fairly new, I do not know the year).
