- SAIC Motor announced that blind pre‑orders for the MG 4X electric SUV with a semi‑solid‑state battery will open on May 11, 2026.
- MG 4X will be offered with a 53.9 kWh semi‑solid manganese‑based lithium‑ion pack (up to 510 km CLTC range) or a 64.2 kWh CATL‑supplied LFP pack (up to 610 km CLTC range).
- SAIC Motor equips the base MG 4X with a 125 kW (167 hp) rear‑mounted motor, while higher‑trim models receive a 150 kW (201 hp) motor.
- Oppo co‑developed the MG 4X’s intelligent cockpit, featuring a 15.6‑inch 2.5K infotainment display and a driver‑cluster screen.
- SAIC Motor claims its semi‑solid‑state battery reduces liquid electrolyte to 5%, lowering combustion risk and extending cycle life, a claim corroborated by needle‑penetration tests.
Why it matters: Chinese consumers gain a safer, longer‑range EV at a competitive price, while SAIC secures a tech edge; CATL and Oppo benefit from new supply and partnership deals, boosting the domestic EV ecosystem.
