BYD Qin can switch between gasoline and electric power by selecting different driving modes. The driving modes available for BYD include: Pure Electric + Economy, Pure Electric + Sport, Hybrid + Economy, and Hybrid + Sport. The second-generation DM technology equipped in BYD Qin features four working modes, namely EV+ECO, EV+SPORT, HEV+ECO, and HEV+SPORT. Below is an introduction to the HEV+ECO working mode: 1. In HEV+ECO mode, different power distributions are applied under various conditions to achieve optimal comprehensive economy, allowing for free switching. 2. When the starting speed is below 40 KM/H, the vehicle is driven purely by electric power. When the speed exceeds 40 KM/H and the engine is within the economical fuel consumption range (1500-3500 RPM), the vehicle is driven by fuel. 3. During acceleration or climbing, the engine speed gradually increases. The electric motor responds faster than the engine, reacting before the engine exits the economical fuel consumption range. When assisting the engine, the engine remains within the economical fuel consumption range.

I've been driving the Qin hybrid for almost a year now, and switching between fuel and electric modes is super convenient. After starting the car, simply press the EV or HEV button on the center console: a light press switches to pure electric mode, making city driving as quiet as gliding while saving on fuel costs; press it again to return to hybrid mode, where the engine kicks in on highways to provide power. The system also switches automatically—when battery level drops below 15% or speed exceeds 60 km/h, it automatically shifts to hybrid mode to prevent you from getting stranded. I love this seamless transition; you barely notice it while driving, except for a slight sound during gear shifts. Charging frequently allows longer electric driving, reducing fuel costs—remember to prioritize pure electric mode in heavy traffic to save significantly on daily commutes.

As a driver who has owned several hybrid vehicles, I find switching between the Qin's electric and hybrid modes effortless. Start the vehicle, locate the EV or HEV mode button near the steering wheel, and manually switch with straightforward ease. The automatic features are even more thoughtful—for instance, it operates purely on electric power when battery levels are high or during low-speed city driving, while the engine automatically engages in hybrid mode during steep climbs or rapid acceleration. I recommend setting the mode before departure: prioritize electric power in the city and switch to fuel on highways to reduce consumption. Battery maintenance is crucial—I frequently charge to ensure sufficient power and minimize frequent mode shifts. This design is both safe and efficient, offering a worry-free drive without compromising comfort.

I'm very environmentally conscious, and driving the Qin in pure electric mode easily achieves low-carbon emissions. Simply press the EV button to switch to zero-emission mode, enjoying a quiet and comfortable ride throughout. The system automatically switches to hybrid mode when the battery is low, ensuring uninterrupted operation. I usually commute using pure electric mode, reducing engine usage and exhaust emissions to lessen the environmental burden. The transition is smooth and doesn't affect driving, while developing a charging habit increases the pure electric usage rate.
