Mild Hybrids auxiliary belt every 4 years now?

Just been looking at the service schedules for the mild hybrids. Am I right in assuming the fact the auxiliary belts are recommended to be replaced :

Every 72 000 miles/4 years - Renew (LTS 21 567 5)

Is because they are used in the mild hybrid system?

Anyone know how much it costs roughly from a ford dealership? Presumably it should be similar in price to the pre hybrids?

I checked on whatever ETIS is now called across Fiesta/Focus/Puma and they all have roughly the same mileage and all have 4 years renew advised.

    The mild hybrid system is belt driven so presumably Ford have found the additional strain has shortened the belts life.

    Yes, I've mentioned the 4 year aux belt on here before.

    None of the mild hybrids have reached 4 years old yet though, so haven't seen any prices so far.

    I suspect the cost will be higher than the "normal" belts because the extra loads (as Alex mentions) will require a stronger material, etc. It will be interesting to find out!

    I have an idea the belt replacement interval was around 72k anyway, but for mhev they have introduced the time element as well, as with cambelts?
