Which mode is the most fuel-efficient for BYD Qin DMi?
4 Answers
BYD Qin DMi is most fuel-efficient in pure electric mode. Modes of BYD Qin DMi: The BYD Qin DMi has four modes in total: series, parallel, pure electric, and hybrid mode, catering to daily driving and various road conditions. The fuel-saving aspect of BYD Qin DMi is most evident in urban areas, with the highway defaulting to hybrid mode. Do not assume that you can run on pure electric until the battery is depleted and then switch to hybrid mode, charging back to 70% before returning to pure electric mode. This method yields the same fuel consumption as using hybrid mode continuously, if not higher. How to switch modes in BYD Qin DMi: The BYD Qin hybrid mode switching is automatically controlled by the computer, with the engine intervening at certain speeds. It can also be manually controlled, switching directly between hybrid and pure electric modes.
My experience driving the BYD Qin DM-i over the past few years is that pure electric mode is the most cost-effective and hassle-free option. As long as the battery has sufficient charge, switching to EV mode and relying entirely on electric power brings fuel consumption down to zero. City commuting becomes quiet and smooth, with seamless acceleration that doesn't consume any fuel. Real-world testing shows a full charge can cover over 100 kilometers, with electricity costs amounting to just a few cents per kilometer—far more economical than gasoline. When battery levels drop, the system automatically switches to hybrid mode. But for maximum fuel savings, you need to set an SOC preservation strategy: use HEV economy mode on highways with the engine running at low speeds to optimize power supply. Take advantage of public charging stations during off-peak hours when electricity rates are cheaper; avoid flooring the accelerator from a standstill, as smooth driving can improve efficiency by about 15%. Pure electric mode is the optimal choice, provided you charge frequently.
As a daily user, I believe the pure electric (EV) mode offers the best cost-saving benefits, especially in urban driving conditions. With sufficient battery, activating EV mode eliminates fuel consumption entirely, significantly reducing monthly commuting costs. I charge after work every day, spending just a few dollars to cover 100 kilometers. For long-distance trips, I switch to HEV hybrid mode in the economy setting, where the engine assists power supply without increasing fuel consumption—actual tests show highway fuel economy below 5 liters per 100 km. The key is to monitor the battery display closely, setting a higher state of charge (SOC) in advance to prevent depletion. Maintain steady speeds while driving and maximize energy recovery to minimize braking losses. In winter, be mindful of heating power usage to avoid rapid EV battery drain. Overall, pure electric mode is economical, but charging convenience and habits are crucial.
The most fuel-efficient mode for my DM-i is pure electric EV. Use it when the battery is sufficient, achieving zero fuel consumption. For daily commuting, I mostly drive in full EV mode and charge at night. For long highway trips, switch to HEV hybrid mode and select the energy-saving option, where the engine optimizes power supply to reduce fuel consumption. Set a reasonable SOC to preserve battery power and switch to EV mode when entering the city. Smooth acceleration and minimal hard braking improve energy efficiency. Frequent charging keeps costs low, with actual tests showing just a few cents per kilometer. Even in hybrid mode without battery power, it's more economical than pure gasoline. Using charging stations is key, as EV mode is the most cost-effective.
