New Renault Master E-Tech electric’s WLTP range – up to 460 km

Renault has chosen two batteries optimised for capacity, size and mass, combined with in-depth work on aerodynamics and a brand-new innovative platform. The van comes with a choice of two energy storage capacity ratings: 40 kWh and 87 kWh. These two packs are built into a single casing and designed for driving requirements in cities as much as in suburbs. And they do not hamper the vehicle’s payload capacity – which is an essential criterion in this segment.
