What matters

Both selected versions are 6-seat, all-wheel-drive M8 models with the same family-vehicle footprint: 5,190 mm x 1,999 mm x 1,795 mm, a 3,105 mm wheelbase, and a claimed 0-to-100 km/h time of 5.2 seconds. Space, parking fit, and straight-line performance therefore do not resolve this choice. Charging access and the meaning of each range figure do.

Key differences

  • The EREV Max+ combines a 53.4 kWh battery with a claimed 310 km CLTC electric range, then uses fuel backup to reach a claimed 1,526 km CLTC total range from a full tank and full charge. Its peak charging claim is 201.2 kW. The practical benefit is route flexibility when a reliable charger is not waiting at every regular stop.
  • The EV Ultra carries a 100 kWh battery, a claimed 625 km CLTC battery-electric range, and a 290 kW peak charging claim. With dependable home and route charging, that supports full-electric daily use and longer trips without retaining a fuel engine.
  • The official six-seat matrix lists EREV Max+ at CNY 399,800 and EV Ultra at CNY 449,800. The CNY 50,000 gap is before options, insurance, taxes, incentives, or transaction discounts, and it includes equipment differences between Max+ and Ultra. Compare the trim content you would actually order before assigning the whole premium to the battery.

Who it is for

  • Pick the EREV Max+ if apartment charging, holiday routes, rural travel, or recurring long drives leave meaningful charging gaps. Fuel backup and the lower listed price reduce planning risk, even though daily ownership still includes a combustion system.
  • Pick the EV Ultra if you can charge reliably at home and along your real routes, intend to drive fully electric, and will use the larger battery and higher peak charging rather than merely paying for the larger headline figures.

Watch-outs

  • Do not compare the EREV's total CLTC range directly with the EV's electric CLTC range. Temperature, speed, driving style, battery state, charger, wheels, and options can also move real range and charging speed away from the official claims.
  • Ownership costs split in different directions: the EREV can add fuel and engine maintenance, while the EV can add charging installation, charging time, and the higher trim price.
  • Buy neither before checking real six-seat comfort, parking fit, route energy use, insurance, option cost, and local charging conditions. The shared body is large, and neither certification range figure replaces a route audit.
