I’m not sure which issues you refer to, but the e-Power is roughly 210kg heavier than the DIG-T 158 (1459kg to 1670kg). Which is in line with any other PHEV in terms of weight gain, except you only get 15-20%ish of the battery size? It’s not even a PHEV in the first place, what am i missing?
As a guide, because its difficult comparing like for like accross manufacturers.
The Qashqui E-power Tecna has a kerb weight of 1636kg, The Pug 3008 PHEV has a kerb weight of 1800kg, but the smaller last gen Kia Nero PHEV had a kerb weight of 1519kg and the bigger Kuga FHEV has a kerb weight 1855kg.
