NIO (蔚来) says 48V integrated suspension is a generation ahead of 400/800V split systems

NIO's claim at the ES9 launch

It has been reported that NIO (蔚来) founder, chairman and CEO Li Bin (李斌) used the ES9 flagship SUV launch to make a forceful technical claim: the company's 48V integrated full active suspension is "one generation ahead" of the more common 400/800V split solutions. The new ES9 ships with NIO's Tianxing (天行) 48V integrated active suspension, which Li said delivers five advantages — more agile, more precise, more energy‑efficient, quieter and more comprehensive vehicle control.

What 48V integrated means, and why NIO argues it matters

In plain terms, a 48V integrated approach consolidates actuation and distribution for vehicle subsystems closer to a modest-voltage architecture, whereas 400/800V split systems separate high-voltage powertrain rails from lower-voltage auxiliary systems. NIO argues that for active suspension — which requires fast, distributed electrical actuation — the lower-voltage, integrated layout offers simpler packaging and finer control. Li Bin framed the case around ride quality and efficiency rather than raw powertrain performance.

Industry context and wider significance

Li Bin reportedly predicted that 48V integrated active suspension will become the industry standard for the next generation of battery electric vehicles, and he said Tesla's Cybertruck uses a 48V power distribution architecture as well. Architecture choices like these matter beyond handling: they shape supplier ecosystems, chip and component demand, and resilience amid rising geopolitical scrutiny of advanced automotive electronics. Will rivals follow NIO's bet on lower‑voltage integration? The claim positions NIO squarely in the debate over how software, electrification and supply chains will define the next wave of EV differentiation — but market adoption, not rhetoric, will decide the winner.
