Risk of rusting in exhaust system?

[Glen Tindall]

A question for you folk in U.K., and Europe - as you have had plug-in hybrids longer than us Antipoedians, have you seen any problems with rusting exhaust systems due to the short runs of the petrol engine before going into ev mode? We were always told that not heating the system up through short runs causes rusting through the system not fully heating up completely, leaving water in the exhaust system. Love the ev mode, but are we creating problems by having the short runs on petrol mode?

I had a Toyota for like 15 years. Toyota Corolla petrol.

My travel to work is 24km, from and to.

So short distance.... Never had any exhaust issues. By this is Toyota we are talking about..... It all depends on the chosen metal for the exhaust I think...

The short runs I was thinking of is the 2-3 kms of petrol while the heating, charge mode, or demister are in play. These wouldn't heat the exhaust as thoroughly as a 24 kms run.

Stainless steel exhaust systems are the answer. Whether or not this is factored in is another matter!
