Denza Reveals Z9S Sedan With 102.3 kWh Battery and 920 km CLTC Range

The official MIIT filing gives battery and motor specs for the smaller Z9S while supplier differences and unverified reports mean independent tests remain needed.

Overview

  • Denza published official images and product details on Friday that, together with a China MIIT filing, list a 102.326 kWh battery and two rear‑wheel‑drive motor outputs roughly 429 hp and 496 hp with a CLTC range claim up to about 920 km.
  • The Z9S is a smaller fastback sedan than the Z9, measuring about 5,090 mm long with a 3,025 mm wheelbase, and the reveal highlights visible ADAS hardware including a roof‑mounted LiDAR and camera.
  • Reporting from CarNewsChina indicates Denza will source battery cells and final pack assembly from different suppliers across variants, which can produce measurable differences in energy density and thermal behavior between trims.
  • An AutoHome listing not included in the MIIT paperwork shows a putative tri‑motor Z9S near 1,200 hp but that variant is unconfirmed and should be treated as speculative until Denza or regulator filings verify it.
  • A separate first‑person autobahn account described a sudden high‑speed steering event in the larger Z9 GT, and experts note MIIT filings and CLTC range figures do not replace independent safety and real‑world range testing that buyers and regulators rely on.
