What is the top speed of the BYD Qin Plus DM-i?
3 Answers
The top speed of the BYD Qin Plus DM-i is 185km/h. Relevant information about the BYD Qin Plus DM-i is as follows: 1. The Qin PLUS-DM-i is a plug-in hybrid vehicle. It is equipped with the DM-i Super Hybrid System, which consists of the Xiaoyun 1.5L plug-in hybrid dedicated engine, EHS hybrid system, and Blade Battery. The engine has a maximum power of 81kW and a maximum torque of 135N·m, while the motor offers two options: 132kW and 145kW. The transmission is matched with an E-CVT gearbox. 2. The interior is full of futuristic technology. Standard features include cruise control, a 10.1-inch large screen, OTA remote upgrade, rearview camera, LED headlight group, etc. The ultimate configuration also includes an L2 autonomous driving system and wireless phone charging. 3. It has strong practicality. With dimensions of 4765/1837/1495mm and a wheelbase of 2718mm, the interior space is very spacious, and the trunk is also relatively large.
I've been driving the BYD Qin Plus DM-i for almost a year now. I remember the top speed is 185 km/h, and I tried 170 km/h on the highway—it felt quite stable, but the wind noise increased noticeably. For daily driving, I usually cruise at around 60 km/h in the city or 110 km/h on the highway. At these speeds, the power delivery is smooth and fuel-efficient, with my actual average fuel consumption being just 4-5 liters. The vehicle's weight and suspension design provide good control at high speeds, but pushing it harder can cause fuel consumption to spike easily beyond 6 liters. Safety-wise, it's more prone to slipping in rainy or foggy conditions. I recommend not risking it by chasing the top speed—185 km/h is more than enough for daily use, and driving comfortably is far better than pushing the limits. My real-world experience shows that the hybrid system performs more efficiently with steady driving, which also helps extend the vehicle's lifespan. Driving slower actually makes for a more worry-free experience.
From a technical perspective, the BYD Qin Plus DM-i's top speed is calibrated at 185 km/h, largely thanks to its DM-i hybrid system. The 1.5-liter Xiaoyun engine and electric motor work in perfect harmony during high-speed phases, with the engine taking over as the primary power source beyond 120 km/h to ensure smooth output. The 185 km/h design limit is a comprehensive consideration of aerodynamics, tire grip, and energy consumption balance, as fuel consumption rises above 6 liters at high speeds, unlike the more economical low to medium speeds. I've also noted the vehicle's ECU finely adjusts power distribution to prevent overload. Overall, the top speed setting is reasonable, designed for functional coverage rather than racing. Driving this car, acceleration up to 150 km/h is smooth, but approaching 180 km/h, the engine's high RPM signals a drop in efficiency.
