What is the maximum speed of the Song Plus DM-i?

160 kilometers per hour is the maximum speed of the Song PLUS-DMi, but the speed limit on highways is capped at 120 kilometers per hour. The maximum speed of the Song PLUS-DMi does not refer to the instantaneous top speed of the car, but rather the stable maximum speed, which is one of the indicators used to measure a vehicle's maximum power. The maximum speed of the Song PLUS-DMi is related to factors such as wind resistance, maximum power, and transmission ratio. If the maximum power is constant, the lower the wind resistance, the higher the car's maximum speed. When the car is traveling at its maximum speed, the driving force is in balance with the total resistance the car encounters, primarily from air resistance. When the engine outputs its maximum power and the car is moving at a constant speed, the car reaches its maximum speed. The larger the transmission ratio, the lower the car's speed will be. However, typically, a car can only reach its maximum speed when the power and resistance are balanced. The energy type of the Song PLUS-DMi is plug-in hybrid. The battery type for the four-wheel-drive version is front and rear dual-mounted lithium iron phosphate batteries, while other versions use a single front-mounted lithium iron phosphate battery.
I've been driving this Song Plus DM-i for a while now. Its official top speed is around 175 km/h, but in my actual tests on flat roads, I've managed to hit 180 km/h. On highways, I usually keep it under 120 km/h. To be honest, speed racing isn't its forte - hybrids excel more in fuel efficiency. The pure electric mode is very quiet in the city, but the engine noise becomes noticeably louder when it kicks in on highways. A safety reminder: speeding carries significant risks. While the body remains fairly stable even with high wind resistance, it tends to feel floaty during sharp turns. For daily commuting, the speed is more than adequate. I'd recommend regular checks on tires and brakes, as higher speeds not only cause fuel consumption to spike but may also lead to component wear.
Regarding the Song Plus DM-i's top speed, I recall the standard model can reach 175 km/h. This stems from its 1.5L engine and electric motor combination with limited total power output, combined with vehicle weight and comfort-oriented economical design. At high speeds, the system switches to fuel-dominant mode, but reaching top speed takes tens of seconds, unlike performance vehicles. Influencing factors include a drag coefficient around 0.3 - additional load or AC usage may slightly reduce speed. For details, consult the user manual as different configurations may have minor variations, but 175 km/h is generally the limit. Emphasizing safe driving - do not exceed speed limits.
