Which mode is the most fuel-efficient for the BYD Qin DM-i?
3 Answers
BYD Qin DM-i is most cost-effective in pure electric mode. Advantages: The BYD Qin Plus is the first model equipped with BYD's DM-i Super Hybrid Technology. The latest DM-i Super Hybrid Technology released by BYD is a hybrid technology primarily based on electricity, offering multiple advantages such as fast acceleration, quiet operation, smooth driving, and environmental friendliness. Powertrain Configuration: The BYD Qin Plus DM-i hybrid version is equipped with a self-developed 1.5T inline four-cylinder engine, codenamed BYD476ZQA. This self-developed engine has a maximum power output of 154 horsepower and a maximum torque of 240 N·m. The electric motor has a maximum power output of 150 horsepower and a maximum torque of 250 N·m. Combined, the entire hybrid system can deliver a total of 295 horsepower and 479 N·m of torque.
What I love most about driving the BYD Qin DM-i is using EV mode for my daily commute – it's absolutely the most fuel-efficient option since it runs purely on electricity without burning any fuel. I mainly drive in the city for short commutes under 20km, and the battery is more than sufficient. Overnight charging is very affordable. Switching modes is straightforward – just press the EV button after starting the car, no hassle needed. On highways, I occasionally use HEV hybrid mode, and even with the engine engaged, fuel consumption remains low at around 5L/100km. But for pure city driving, EV mode with zero fuel consumption is the most cost-effective – each charge costs just a few yuan, far cheaper than refueling. Remember to enable Eco mode assistance and set the regenerative braking one level higher to save more energy. Driving like this long-term can save thousands in fuel costs annually – highly recommended. The key is maintaining sufficient battery charge; don’t wait until it’s low to recharge. With good habits, everything works perfectly.
I believe the BYD Qin DMi is most fuel-efficient in combined mode, where flexible switching maximizes savings. From my own driving observations, using EV pure electric mode for short city trips with sufficient battery results in zero fuel consumption; switching to HEV hybrid mode for long-distance or highway driving keeps the engine working efficiently with low fuel consumption, maintaining a steady 4.5-5L/100km on highways. Don’t forget to enable Eco mode to further reduce energy consumption. The key lies in battery status and driving habits: prioritize EV when the battery is high to save significant fuel costs; when the battery is low, HEV auto-generates power without waste. Regular maintenance, such as cleaning filters, helps prolong efficiency. Tests show that mixed usage yields an average monthly fuel consumption of around 3-4L/100km, saving over half compared to pure gasoline cars. This car is designed for energy efficiency—choosing the right mode and driving smoothly ensures excellent overall energy management, saving both money and hassle.
