1. Combustion Engine and Electric Traction Core

Under the hood sits a 1.5-liter, naturally aspirated engine that produces 74 kW of peak output. Operating primarily as a high-efficiency generator to sustain battery voltage or provide direct assist under high load, this motor is paired with a powerful, permanent magnet electric motor. The electric drive unit delivers an individual output of 175 kW (equivalent to 235 PS), providing the instant throttle response and silent torque characteristics typically reserved for battery-electric vehicles (BEVs).

2. Blade Battery Capacities and Extraordinary Range Profiles

Energy management is handled by BYD’s signature, lithium iron phosphate (LFP) advanced blade battery pack, which is integrated directly into the floor structure for improved crash safety and chassis rigidity. Buyers can tailor the crossover to their driving habits by selecting between two distinct battery capacities:

26.6 kWh Battery Variant: Delivers a highly competitive pure electric driving range of up to 205 kilometers under standard testing cycles, allowing for weeks of emissions-free urban commuting without burning fuel.
38.0 kWh Battery Variant: Pushes electric capability even further, securing an incredible 310 kilometers of zero-emission driving on a single charge.

The most impressive metric emerges when the dual-mode framework works together. With a fully topped-off fuel tank and a 100% battery state-of-charge (SoC), the Song Ultra DM-i achieves an exceptional highway range of up to 1,845 kilometers. This eliminates range anxiety for long-distance cross-country travel. Even when the battery pack is completely depleted, the system operates as a traditional hybrid, achieving an impressive depleted battery fuel consumption rate of just 3.3 liters per 100 kilometers.
