...I'll put the tinfoil hat on and come up with a mad conspiracy theory here...Peugeot didn't design the wetbelt system.
Around 2010 there was a industry supplier called Dayco wandering round selling wetbelts as a solution to lower emissions and better performance. Both Ford and PSA bought the system, however their implementation and responses to the issues caused were significantly different. To be fair the Ecoboost came to wetbelt issues late as few early ecoboosts lived long enough to suffer belt failure with all the other issues they had.
Peugeot are buying up all the brands... and fitting the last generation of ICE cars with terrible, wet-belt short-lasting engines that won't last half the life as most of the buyers previous 207 or C3 ... but now, or Corsa or Panda or etc. So that when they've had lots of trouble with engines, suddenly the BEV models appear to be a way out of ever having oil...belt...turbo issues ever again!
And Ford, well, Ford looked at it differently. They saw the Tesla fires and thought, 'if we make our new petrol engine extremely likely to go on fire, buyers won't dismiss our BEVs as fire hazards since they will know the ICE choice is as bad!'
