Summary
The two biggest Chinese plug-in hybrid rivals in Europe: BYD Seal U DM-i taking on the popular MG HS II Plug-in Hybrid.
Verdict
The MG HS II offers a larger 21.4 kWh battery with 120 km WLTP range and a trusted 7-year European warranty. The BYD Seal U DM-i counters with ultra-safe Blade LFP technology, 18 kW DC rapid charging, and a noticeably more tech-forward rotating cockpit.
