Powertrain & Engine Architecture
The Song Pro DM-i utilizes BYD’s DM-i hybrid system, which centers around a 1.5-liter naturally aspirated four-cylinder gasoline engine (BYD472QA) paired with a single electric motor. The engine produces 101 horsepower and 92.93 lb.-ft. of torque. The electric motor delivers 163 horsepower and 154.89 lb.-ft. of torque. The combined system output is 163 horsepower. The engine employs multi-point fuel injection and a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT) to optimize efficiency. The E-CVT (electronically controlled continuously variable transmission) doesn’t have fixed gears like a traditional automatic; instead, it uses a combination of the engine and electric motor to provide seamless acceleration. The 18.3 kWh lithium iron phosphate (LiFePO4) battery pack is positioned under the floor, contributing to a lower center of gravity and maximizing cabin space. The DM-i system is designed to prioritize electric driving whenever possible, switching to the gasoline engine only when the battery is depleted or when extra power is needed.
Driving Characteristics
The 1.5L DM-i powertrain delivers a smooth and refined driving experience, particularly in electric mode. Acceleration to 60 mph takes approximately 8.1 seconds, which is competitive within the compact SUV segment. The E-CVT provides seamless power delivery, eliminating the shift shock often associated with traditional automatic transmissions. In hybrid mode, the engine operates efficiently, often acting as a generator to recharge the battery while driving. Compared to higher-output gasoline-only versions of the Song Pro, this variant prioritizes fuel economy over outright performance. The steering is light and precise, making it easy to maneuver in urban environments. The suspension is tuned for comfort, absorbing bumps and providing a stable ride.
Equipment & Trim Levels
The Song Pro DM-i typically comes well-equipped, even in its base trim. Standard features generally include LED headlights, a large touchscreen infotainment system with smartphone integration, a digital instrument cluster, automatic climate control, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane departure warning, and automatic emergency braking. Interior upholstery is typically cloth or synthetic leather, with higher trims offering genuine leather options. Optional extras may include a panoramic sunroof, heated and ventilated front seats, a premium sound system, and a 360-degree camera system. The specific trim levels and available options vary depending on the market.
Chassis & Braking
The Song Pro DM-i features a front-wheel-drive layout. The front suspension utilizes an independent McPherson strut design, while the rear suspension employs an independent multi-link setup. This configuration provides a good balance of ride comfort and handling. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The vehicle is equipped with an anti-lock braking system (ABS) and electronic stability control (ESC) as standard safety features. The steering system is an electric power steering (EPS) system, providing light and responsive steering feel.
Market Reception & Comparison
The BYD Song Pro DM-i has been well-received in the Chinese market, praised for its fuel efficiency, comfortable ride, and advanced technology. Critics have noted its competitive pricing and spacious interior. Compared to gasoline-only versions of the Song Pro, the DM-i offers significantly better fuel economy, particularly for drivers who frequently commute in urban areas. The DM-i also provides the benefit of electric-only driving for shorter trips, reducing emissions and operating costs. Compared to other plug-in hybrid SUVs in its class, the Song Pro DM-i offers a compelling combination of performance, features, and value.
Legacy
The BYD Song Pro DM-i represents a key step in BYD’s transition towards becoming a leading global manufacturer of electric and plug-in hybrid vehicles. The DM-i technology has proven to be reliable and efficient, and the Song Pro DM-i has become a popular choice among Chinese consumers. As BYD expands its presence in international markets, the Song Pro DM-i is expected to play a significant role in driving the adoption of plug-in hybrid technology. The longevity of the LiFePO4 battery chemistry is a key selling point, known for its stability and long cycle life, suggesting good long-term reliability for this powertrain. On the used car market, well-maintained examples of the Song Pro DM-i are expected to hold their value due to their fuel efficiency and technological features.
