What are the four modes of BYD Qin DM-i?

[LeMia]

BYD Qin equipped with the second-generation DM technology has four working modes, namely EV+ECO, EV+SPORT, HEV+ECO, and HEV+SPORT. Especially in HEV+ECO mode (under different working conditions, different power distributions are made to achieve optimal comprehensive economy.), free switching can be achieved. The following are the relevant details: 1. Starting speed: When the starting speed is below 40KM/H, it is driven by pure electric power; when the speed exceeds 40KM/H and the engine is in the economic fuel consumption zone (1500-3500 rpm), it is driven by fuel; 2. During acceleration: During acceleration or climbing, the engine speed gradually increases, and the motor responds faster than the engine, responding before the engine leaves the economic fuel consumption zone, assisting the engine to keep it within the economic fuel consumption zone.

The four modes of the BYD Qin DM-i are quite practical, and I must say it's very smooth to drive daily. The EV mode is purely electric-driven, suitable for short city trips or during traffic jams—it's especially quiet and fuel-efficient. In HEV series mode, the engine generates electricity to power the motor, functioning like a range extender, which is ideal for acceleration or hilly roads. HEV parallel mode combines the power of both the engine and motor, delivering super strong performance—perfect for highways or urgent overtaking. Lastly, HEV engine direct-drive mode engages the engine to drive the wheels directly during high-speed cruising, ensuring high efficiency and saving battery power. I find switching between these modes quite intelligent—the system adjusts automatically but also allows manual selection. Over time, the vehicle system learns driving habits to help save even more on fuel, especially in traffic jams where EV mode extends battery range. I recommend owners experiment with different scenarios to enhance the overall driving experience and energy efficiency. Overall, this mode design makes the Qin DM-i reliable for both city and long-distance driving.

As someone who enjoys delving into technology, I find the four driving modes of the BYD Qin DM-i ingeniously designed. The EV mode operates purely on electric power, offering zero emissions and quiet operation; the HEV series mode uses the engine to generate electricity and drive the motor, making it ideal for medium-low speeds or climbing, thus saving energy; the HEV parallel mode sees the engine and motor working together to deliver high torque, which is incredibly powerful for highway driving or overtaking; and the HEV engine direct drive mode directly powers the wheels at high speeds, reducing energy loss. The transitions between modes are smooth, with no noticeable jerking, thanks largely to system optimization. Having driven several hybrid models, I can say the Qin DM-i's intelligent switching is the most seamless, especially during rapid acceleration or deceleration. For long-term use, it's also important to pay attention to battery maintenance, often keeping it in balanced mode. In summary, these modes make the car more durable and environmentally friendly, contributing significantly to energy savings and emission reduction.

The four modes of Qin DM-i are all about saving money. The EV pure electric mode is the most fuel-efficient for urban commuting, hardly using any fuel. The HEV series mode, where the engine generates electricity to drive, is suitable for traffic jams or hilly areas with low fuel consumption. The HEV parallel mode offers quick acceleration but uses both fuel and electricity, resulting in slightly higher fuel consumption, so it's best used only when extra power is needed. The HEV engine direct drive is efficient for high-speed cruising, saving electricity and providing a smooth ride. Owners can manually select modes or let the system adapt automatically. Using the EV mode more often can extend battery life. After driving for a year, I've saved a lot on fuel, especially during rush hours by avoiding high-cost routes. If charging is quick, the EV mode can cover even more distance.
