Powertrain & Engine Architecture
The heart of the Song Pro DM-i is its plug-in hybrid powertrain. It combines a 1.5-liter naturally aspirated four-cylinder gasoline engine (BYD472QA) with an electric motor and a 12.9 kWh lithium iron phosphate (LiFePO4) battery pack. The gasoline engine produces 101 horsepower and 92.93 lb.-ft. of torque, while the electric motor delivers 163 horsepower and 154.89 lb.-ft. of torque. The system’s combined output is 163 horsepower. The engine utilizes multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT). The E-CVT (electrically controlled continuously variable transmission) is a key component, allowing for seamless transitions between electric and gasoline power, and optimizing efficiency. Unlike traditional CVTs, the E-CVT uses an electric motor to provide continuously variable ratios, eliminating the need for a conventional belt and pulley system. The battery pack is located under the floor, minimizing impact on cabin space.
Driving Characteristics
The DM-i system prioritizes electric driving whenever possible. Under normal driving conditions, the vehicle operates in EV mode, providing a quiet and emissions-free experience. When the battery is depleted or requires additional power, the gasoline engine seamlessly kicks in to provide propulsion or recharge the battery while driving. The E-CVT contributes to smooth acceleration and a lack of noticeable gear changes. While not a performance-oriented vehicle, the 8.3-second 0-60 mph acceleration is respectable for its class. Compared to higher-output gasoline-only versions of the Song Pro, the DM-i offers a more refined and fuel-efficient driving experience, albeit with slightly less overall power. The E-CVT’s programming focuses on efficiency rather than aggressive acceleration, making it well-suited for urban commuting and highway cruising.
Equipment & Trim Levels
The Song Pro DM-i 1.5L typically comes well-equipped, reflecting its mid-range positioning. Standard features generally include LED headlights, a large touchscreen infotainment system with smartphone connectivity (Apple CarPlay and Android Auto), 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 a combination of fabric and leatherette. Optional extras may include a panoramic sunroof, heated and ventilated front seats, a premium sound system, and upgraded interior trim materials. The specific trim levels and available options can vary depending on the market.
Chassis & Braking
The Song Pro DM-i utilizes an independent McPherson strut suspension in the front and an independent multi-link suspension in the rear, providing a comfortable ride and stable handling. Ventilated disc brakes are used on the front wheels, while the rear wheels are equipped with disc brakes. The electric power steering (EPS) system offers light and precise steering feel. The vehicle is equipped with ABS (Anti-lock Braking System) and electronic stability control (ESC) as standard safety features. Tire size is typically 225/60 R18, mounted on 18-inch alloy wheels.
Market Reception & Comparison
The BYD Song Pro DM-i has been well-received in the Chinese market, where it competes with other popular plug-in hybrid SUVs. Critics have praised its fuel efficiency, comfortable ride, and advanced technology. Compared to the gasoline-only versions of the Song Pro, the DM-i offers significantly better fuel economy and lower emissions. It also provides the benefit of electric-only driving for shorter commutes. Compared to other plug-in hybrid SUVs in its class, the Song Pro DM-i offers a competitive price point and a generous all-electric range. Reliability reports are still emerging, but BYD has a growing reputation for building durable and well-engineered vehicles.
Legacy
The BYD Song Pro DM-i represents a key step in BYD’s transition towards becoming a leading global manufacturer of new energy vehicles. The DM-i powertrain technology has proven to be popular with consumers, and it is expected to be incorporated into other BYD models in the future. The long-term reliability of the DM-i powertrain remains to be seen, but the use of LiFePO4 battery technology is generally considered to be safe and durable. As the used car market expands, the Song Pro DM-i is likely to become a sought-after option for buyers looking for a fuel-efficient and technologically advanced SUV.
