No starter and no alternator? Hybrids don’t have an electric motor or a way to turn mechanical power into electrical power? Also they don’t have timing belts?

I’m not super convinced that accessory belts are a major cause of maintenance. I only recall having to do that once at around 120k miles.
I think there is a good argument to be made that implementations like Toyotas HSD are more reliable than plain ICE, but you’re not making it here.
- kayodelycaon 1y agoSince I was specifically talking about Toyota hybrid, let me elaborate… The gas engine has a timing chain and chain-driven oil pump. Everything else runs off the DC-DC converter. The transmission is two motor-generators and an ICE directly connected by fixed gearing. This is used to start the engine. The ICE in a hybrid doesn’t need any accessories beyond what the electric drivetrain already provides. Therefore, it does not have a starter or alternator. There are a lot fewer moving parts that can break or wear out. It’s a pretty elegant system that bolts a bare ICE to what is otherwise an electric car.
