BMW Details Neue Klasse Push as Rimac‑Built Gen6 Battery Heads to Updated i7

The 4695 round‑cell pack promises higher energy density with faster charging, signaling European battery production at scale.

Overview

  • BMW says the refreshed i7 will be its first EV to use a Gen6 battery co‑developed with Rimac that debuts publicly in Beijing later this month.
  • The new 4695 cylindrical cells deliver about 20% higher volumetric energy density than BMW’s prior prismatic Gen5 cells, according to the company.
  • Rimac has outfitted its Zagreb campus to build the high‑voltage packs on a 15,000 m² line sized for about 300,000 modules a year, with finished systems shipped to BMW’s Dingolfing plant.
  • Press reports describe a reworked BMW i3 on the Neue Klasse platform that turns the 3 Series into a full EV, launching as a dual‑motor 50 xDrive rated at 345 kW and 645 Nm.
  • BMW targets i3 production in Munich from August 2026 with first deliveries in autumn, while the current i4 remains on sale with low advertised leases that require a large upfront payment.
