DM-i's fuel consumption at 120 km/h cruising speed is 3.8L. The DM-i system possesses multiple advantages that lead other hybrid technologies, with its 'core concept' being electricity as the primary power source and fuel as supplementary. In terms of architecture, the DM-i Super Hybrid is based on a high-capacity battery and high-power electric motor. During driving, the vehicle relies on the high-power electric motor for propulsion, while the gasoline engine's main function is to charge the battery. Exterior Design: The exterior design is largely consistent with the Qin 100 model, featuring a multi-slat grille integrated with the headlights, offering high recognition and strong overall coherence. The rear still adopts an integrated taillight cluster, with a '5.9s' badge at the back, highlighting BYD Qin's rapid acceleration capability. BYD Engines: The 1.5L engine is mainly used in Qin PLUS and Song PLUS, while the 1.5T turbocharged engine is employed in the larger Tang DM-i model.

I drive a Qin DM-i, and it's already covered over 10,000 kilometers. The fuel consumption of this car is truly impressive. For daily commuting in the city, it mostly runs on electricity, and charging at night costs just a few yuan. Occasionally, when going on long trips with low , the fuel consumption is just over 4L, and the flexibility of gas stations is far superior to electric vehicles. BYD's DM-i technology is indeed amazing—when driving on highways, the engine charges the battery, and in traffic jams, it can switch to electric mode. Last summer, with the air conditioning on, I drove from Shanghai to Hangzhou and recorded only 4.2L. The battery under the seats doesn't affect the interior space, and the biggest surprise is that you don't have to treat it like a sacred object by constantly plugging it into a charging station. Even when running low on battery, it drives just like a regular hybrid.

I recently conducted several fuel consumption tests on the DM-i series. I took the Song DM-i on a mountain road trip with the air conditioning set at 22°C and a load of 300 kg, achieving an actual displayed consumption of 4.3L. Later, I tested it for three consecutive days during Shanghai's morning and evening rush hours in a depleted battery state, with the highest consumption only reaching 4.7L. The official claimed depleted battery consumption of 3.8L requires driving at a constant speed. In real-world usage, adjusting tire pressure to 2.8, setting the air conditioning to ECO mode, and avoiding sudden braking can help most drivers maintain a stable range of 4.2-4.5L. The battery pack is intelligently designed to automatically recover kinetic energy during downhill driving.

Last week, I accompanied my friend to pick up his Han DM-i, and the salesperson gave us a detailed demonstration. When simulating a low- condition in the showroom, the displayed fuel consumption fluctuated between 4.1-4.3L. The EHS hybrid system is most fuel-efficient at 60-80km/h, with quick electric drive response at low speeds. The salesperson mentioned that all DM-i models use the Xiaoyun 1.5L engine, which boasts a globally leading thermal efficiency of 43%. Plug-in hybrid vehicles have much more reasonable fuel tanks compared to pure electric cars, easily exceeding 1,000 kilometers on a full tank. My friend ultimately chose the 121km Premium version, and with the Shenzhen government subsidy, the final price was less than 200,000 yuan.

Just did the first for my brother's Song DM-i at the 4S store, had a long chat with the repair team leader. He said the new vehicle system can actively balance the oil-electric output ratio, with the default fuel consumption limit set at 5.5L. It's recommended to charge at least twice a month with slow charging to protect battery health, as long-term low battery driving will affect engine load. The original semiconductor refrigeration compressor saves 15% more electricity than traditional air conditioning, which is particularly noticeable in traffic jams. Southern users are advised to regularly clean the front condenser, as heat dissipation efficiency directly affects fuel consumption performance.

Last year, I rented a Tang DM-i to drive along the Sichuan-Tibet Highway and specifically checked the fuel consumption at an altitude of 4,000 meters. On the uphill sections of National Highway 318, I consistently used the hybrid mode, and the displayed 5.1L was quite reasonable. On the return trip, I tried the intelligent hold mode set at 70%, and the downhill sections recovered kinetic energy, charging the battery by 15%. I particularly tested the fast-charging feature—using a State Grid charging pile, it took half an hour to charge from 18% to 80%, slower than refueling but more flexible than pure electric. This powertrain performed very stably in high-altitude conditions. The accompanying Pajero had a fuel consumption of 11L, proving that hybrid technology is incredibly friendly for long-distance road trips.
