What are the analyses of the BYD Song Plus DM-i chassis?

[McMariana]

BYD Song Plus DM-i's shock absorbers and springs are integrated, similar to the front MacPherson strut, which saves space. The links are purely links without other uses, and the rear suspension uses a three-link rear suspension. Below is its related introduction: 1. Definition of DM-i: DM-i utilizes an ultra-high thermal efficiency engine and an ultra-efficient EHS hybrid system, paired with power-type blade batteries. These three major components maximize efficiency under technological support, achieving incredible fuel consumption. 2. Advantages of DM-i: Acceleration is very linear, with good speed increase, responsive and precise. No sense of jerking is felt.

The chassis design of the Song PLUS DM-i is quite interesting. The front suspension adopts the common MacPherson strut structure, with a relatively soft tuning of the shock absorbers and springs, making it almost bounce-free when going over speed bumps. The rear suspension is an independent three-link setup, providing good support during driving and effectively controlling body roll when cornering. The battery pack is flat-mounted right in the center of the chassis, lowering the vehicle's center of gravity, which contributes to exceptional stability at high speeds without any feeling of floatiness. However, the ground clearance is approximately 17 cm, so extra caution is needed when driving on rough roads to avoid scraping the underbody. The factory also includes a 2mm-thick aluminum alloy protective plate for the battery pack, offering top-tier protection in its class.

Having driven the Song PLUS DM-i for over 20,000 kilometers, the most notable impressions of its chassis are comfort and stability. The front suspension's damping system is tuned to be quite soft, so running over manhole covers or small potholes barely transmits any bumpiness to the seats. The rear suspension design is particularly friendly to backseat passengers, making them feel comfortable even when going over bumps. What stands out most is the battery layout, which is embedded directly beneath the chassis, giving the car a solid, grounded feel that inspires confidence during high-speed lane changes. The factory-fitted Giti tires offer good grip, though road noise is somewhat noticeable. The ground clearance is sufficient for city driving, but extra caution is needed on rural dirt roads.

The chassis design of this car is quite clever, with a mainstream combination of front MacPherson struts and rear multi-link suspension, delivering both comfort and stability. Placing the battery pack in the middle of the chassis is indeed smart, lowering the center of gravity and making cornering nimble without sluggishness. The suspension does a great job filtering out bumps, so you don't even need to slow down for speed bumps in the city. However, the battery placement slightly reduces ground clearance, so you need to be cautious on rough roads. The manufacturer thoughtfully added aluminum alloy armor to the battery for solid protection. The advantages of the chassis tuning are most evident at high speeds—it remains rock-solid even at 150 km/h without any floatiness, and the tires provide ample grip.
