BMW bumps the 7 Series for 2027, adds all-new battery

The 2027 BMW 7 Series leads the luxury EV segment with a groundbreaking battery chemistry that boosts range by 18% over the outgoing model, achieving 420 miles on a single charge. This new solid-state-inspired pack also cuts DC fast-charging time to 22 minutes for a 10–80% top-up, outperforming the Mercedes EQS by 15 miles and 6 minutes. The upgrade signals BMW's aggressive bet on premium electric sedans, even as overall EV market growth slows to 8% year-over-year. By eclipsing #5’s range figures and charging speed, the 7 Series redefines expectations for full-size luxury EVs.
