I was under the impression that one of the benefits of new Integrated Starter Generator (ISG) design of the 48volt mild-hybrid is that there is no longer a need for a serpentine belt. But it’s worth noting I don’t have a GLS in my driveway yet (Grrr) otherwise I would go out and double check before responding. But I found this as a sanity check - “The ISG eliminates the need for a belt drive for ancillary components at the front of the engine, which reduces its overall length.”https://www.greencarcongress.com/201...23-gle580.html
