Difference Between Song DM and DMi

[LaAndres]

BYD Song DM and DMi differ in the following aspects: 1. Power difference: Although both are plug-in hybrid systems, their engine displacements are different. Both are equipped with turbocharged engines, but the DM model features a 2.0T engine with a maximum power of 192 horsepower and a maximum torque of 320Nm, while the DMi is equipped with a smaller 1.5T engine delivering a maximum power of 139 horsepower and a maximum torque of 231Nm. 2. Motor difference: Besides the engine, their motors also differ. Although both use permanent magnet synchronous motors, the DMi series all come with a front-mounted single motor, available in two versions: 145kw and 160kw. In contrast, the DM series includes not only a rear-mounted single motor version with 180kw but also two models with front + rear dual motors. Therefore, all DM models are four-wheel drive, with two capable of full electric four-wheel drive, while the DMi models are all two-wheel drive.

I've driven both the Song DM and Song DM-i, and found the core difference lies in the powertrain. The Song DM uses a traditional dual-mode hybrid system where the engine can directly drive the wheels, delivering strong acceleration, but it tends to be less fuel-efficient in urban driving with noticeable transitions between electric and petrol modes, especially in traffic jams where it consumes more fuel. The Song DM-i upgrades to an intelligent super hybrid system where the engine primarily acts as a generator to charge the battery, while the motor handles propulsion, resulting in smoother driving. It's particularly quiet and fuel-efficient when starting from traffic lights, with urban fuel consumption dropping to around 1L/100km. The DM-i also offers longer pure electric range per charge. Maintenance-wise, the DM-i's simplified structure might make repairs easier. Overall, the DM-i represents more advanced technology suited for those prioritizing efficiency, while the older DM excels in acceleration and is better for highway driving. Understanding these differences can help buyers choose based on their driving habits and avoid unnecessary fuel costs.

I mainly rely on my car for commuting, so I'm particularly sensitive to fuel consumption. The Song DM requires frequent refueling, especially during peak hours when the fuel consumption surges to over 5L, which feels a bit wasteful. On the other hand, the Song DM-i is much more economical, with the engine working less and most of the time running on electricity, resulting in lower fuel consumption. The savings on fuel costs in a month can buy several meals. Both models support pure electric mode, but the DM-i has a longer range, making short trips almost fuel-free. In terms of charging frequency, the DM-i is more user-friendly, requiring fewer charges for longer usage. In daily driving, the smoothness of the DM-i is more comfortable, unlike the DM, which has noticeable engine noise during acceleration. Overall, I find the DM-i more practical and economical. If you, like me, prioritize daily expenses and convenience, it would be a great choice.

I value the driving experience more. The Song DM accelerates quickly, but it's noisy with noticeable gear shift jerks; the Song DM-i is smooth and quiet, like driving a pure electric car, with fluent power response and better comfort. In terms of fuel consumption, the DM-i is much lower, making it more suitable for frequent start-stop conditions in the city.

From a cost-saving perspective, I focus on long-term expenses. The Song DM is cheaper upfront but has higher fuel consumption, and the fuel costs over two years could exceed the price difference with the DM-i. The Song DM-i has a slightly higher initial price but extremely low fuel consumption, saving a lot in daily use. Maintenance is simpler, with less engine wear. In terms of cost-effectiveness, the DM-i is more economical.

I care about the environment. The Song DM has slightly higher emissions, and its engine-driven mode produces more pollution. The Song DM-i is primarily electric-driven, achieving zero emissions in the city, with lower fuel consumption and a reduced carbon footprint, making it more sustainable. Both require charging, but the DM-i has better energy efficiency optimization, making it more environmentally friendly in the long run.
