Brief Introduction
As gasoline prices hover around 9 CNY per liter, fuel costs have become a heavy burden for car owners. BYD's DM-i super hybrid system offers a compelling solution: its 3.8L/100km fuel consumption in battery-depleted state outperforms conventional gasoline vehicles. For drivers traveling 15,000 km annually, this translates to over 5,000 CNY in annual fuel savings. Beyond numbers, its adaptive performance across urban commutes and long-distance trips redefines cost-efficient mobility.
1. Daily Commuting: The Unseen Cost Saver
Urban commuters face the biggest challenge from high oil prices, but DM-i turns this pain point into an advantage. Take a typical 40km daily round trip: a Volkswagen Lavida 1.5L consumes about 8L/100km, costing 28.8 CNY daily at 9 CNY/L. In contrast, the BYD Qin PLUS DM-i uses just 3.8L/100km even when battery-depleted, cutting the daily cost to 13.68 CNY.
Media tests confirm this efficiency: in extreme 25% SOC (state of charge) conditions, the Qin PLUS DM-i achieves 3.5L/100km in city traffic. For office workers driving 240 days yearly, this means 3,628.8 CNY in annual fuel expenses—5,184 CNY less than the Lavida. The difference becomes more tangible during rush hours, as the DM-i’s electric drive eliminates frequent stop-start fuel waste.
2. Long-Distance Travel: No Anxiety, Low Consumption
Weekend getaways or family road trips once meant frequent gas station stops, but DM-i changes this. Equipped with the 5th-generation DM technology, models like the Seal 06 DM-i boast 2,100km combined range. Even at a steady 120km/h on highways, its fuel consumption stays around 4.37L/100km—far below the 9.8L/100km of the Honda Avancier 2.0T.
A 600km journey exemplifies this advantage: the DM-i uses 22.8L of fuel (205.2 CNY), while a comparable gasoline SUV needs 58.8L (529.2 CNY). The 1.5L high-efficiency engine, with 46.06% thermal efficiency, runs in its optimal 2,000-4,000rpm range during cruising, minimizing waste. Drivers can enjoy the trip without calculating refueling stops.
3. The Tech Behind 3.8L/100km
This efficiency stems from BYD’s integrated technology ecosystem. The core is the "electricity-first" architecture: the EHS hybrid system, with 92% working efficiency, seamlessly switches between five modes. In battery-depleted state, it activates series mode—where the engine only generates electricity at peak efficiency—avoiding inefficient low-speed operation.
The upgraded 1.5L engine employs 16:1 compression ratio and intelligent split cooling to maximize energy conversion. Paired with the Blade Battery’s 94% discharge efficiency, it reduces energy loss during power transfer. Unlike traditional hybrids, the DM-i prioritizes electric drive for 85% of urban journeys, with the engine intervening only when necessary.
4. The 5,000 CNY Annual Savings: More Than Numbers
For private car owners, 5,000 CNY in annual fuel savings covers routine maintenance costs. For ride-hailing drivers logging 30,000 km yearly, the figure doubles to 10,000 CNY—directly boosting income. This advantage persists over time: with oil prices projected to stay high, the DM-i’s cost gap with gasoline vehicles will widen.
Importantly, this efficiency doesn’t sacrifice performance. The Qin PLUS DM-i accelerates from 0-100km/h in 7.3 seconds, outperforming many 1.5L gasoline cars. Its quiet electric drive also enhances comfort, making it a practical choice for both economy and experience.
Conclusion
In the 9 CNY/L oil era, the BYD DM-i isn’t just a car—it’s a cost-management tool. Its 3.8L/100km battery-depleted consumption solves the dual pain points of high fuel costs and range anxiety. For urban commuters and road trippers alike, it delivers tangible savings without compromising convenience or performance. As energy prices rise, choosing DM-i means choosing long-term economic freedom.
