BYD’s 46% Engine vs Volt’s Purist Design: Who Solved Hybrids Better?

Is BYD’s DM-i “over-engineered”—or did it quietly solve the Chevrolet Volt’s biggest weakness?

In this deep technical breakdown, we compare the Chevrolet Volt’s pure series (range extender) philosophy with BYD’s multi‑mode DM-i system (EV / series / engine direct drive / parallel). We answer a brilliant question from a 91-year-old engineer who owned three Volts: Why does BYD use a much more powerful engine in a plug‑in hybrid?

Key topics: thermal efficiency (≈36.5% vs 46.06%), urban vs highway efficiency, range extender double conversion losses, clutch-enabled direct drive, “optimization for the usual” vs “all-scenario readiness,” China’s one‑car family use case, and the future of GPS intelligent energy management.
