2021-2023 BYD Song Pro (facelift ) DM-i 1.5 (197 Hp) E-CVT

The BYD Song Pro DM-i 1.5 (197 Hp) E-CVT, a plug-in hybrid electric vehicle (PHEV), represents a significant step in BYD’s strategy to electrify the Chinese automotive market and beyond. Introduced in November 2021 as part of the Song Pro facelift, this variant was produced through May 2023. It occupies a key position within the Song Pro lineup, offering a balance between fuel efficiency, performance, and affordability. The DM-i designation signifies BYD’s “Dual Mode – intelligent” technology, prioritizing electric driving while retaining the flexibility of a gasoline engine. This model is primarily targeted towards urban commuters and families seeking a practical and environmentally conscious SUV.

Technical Specifications

INTRODUCTION

The BYD Song Pro DM-i 1.5, launched in late 2021, is a compact SUV that leverages BYD’s expertise in battery technology and electric powertrains. It’s built on the Song Pro platform, which itself is based on BYD’s 1HX0 architecture, and represents a significant upgrade in terms of efficiency and driving experience compared to earlier Song Pro models. The DM-i variant specifically targets consumers seeking a practical, fuel-efficient, and technologically advanced vehicle, capitalizing on the growing demand for plug-in hybrid SUVs in China. The 197 horsepower output positions it as a mid-range offering within the Song Pro family, slotting above the standard gasoline-powered models but below potential higher-performance DM-i variants.

Powertrain & Engine Architecture

At the heart of the Song Pro DM-i 1.5 lies a sophisticated PHEV system. The powertrain combines a 1.5-liter naturally aspirated four-cylinder gasoline engine (BYD472QA, often referred to as the “Xiaoyun” engine) with a powerful electric motor. The engine produces 110 horsepower at 6000 rpm and 135 Nm of torque at 4500 rpm. It utilizes multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT) to optimize efficiency. The electric motor, a synchronous design, delivers 197 horsepower and 325 Nm of torque. The system’s total combined output is 197 horsepower. The E-CVT (electrically controlled continuously variable transmission) doesn’t rely on traditional belts and pulleys; instead, it uses the electric motor to seamlessly adjust the gear ratio, providing smooth and efficient power delivery. The 18.3 kWh lithium iron phosphate (LiFePO4) battery pack is positioned under the floor, contributing to a lower center of gravity and maximizing interior space. The DM-i system prioritizes electric driving, with the gasoline engine primarily acting as a range extender when the battery is depleted.

Driving Characteristics

The driving experience of the Song Pro DM-i 1.5 is heavily influenced by its electric powertrain. In typical urban driving scenarios, the vehicle operates solely on electric power, offering near-silent operation and instant torque. This results in brisk acceleration and a responsive feel. The E-CVT transmission contributes to a seamless and linear power delivery, eliminating the gearshift interruptions found in traditional automatic transmissions. When the battery is depleted or requires assistance during demanding driving conditions (such as highway overtaking), the gasoline engine seamlessly kicks in. The transition between electric and gasoline power is generally smooth and unobtrusive. While the 0-100 km/h time of 7.9 seconds is respectable, it’s not a performance-oriented SUV. Compared to higher-output DM-i variants or gasoline-powered Song Pro models, this version prioritizes efficiency over outright speed. The steering is light and precise, making it easy to maneuver in city traffic.

Equipment & Trim Levels

The Song Pro DM-i 1.5 typically comes well-equipped, reflecting its position as a mid-range offering. Standard features generally include LED headlights, a large touchscreen infotainment system (often exceeding 12 inches), 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, with options for full leather available on higher trims. Optional extras often include a panoramic sunroof, heated and ventilated front seats, a premium sound system, and a 360-degree camera system. The overall interior design is modern and minimalist, with a focus on functionality and user-friendliness.

Chassis & Braking

The Song Pro DM-i 1.5 utilizes a McPherson strut suspension setup at the front and an independent multi-link suspension at the rear. This configuration provides a good balance between ride comfort and handling. The suspension is tuned to prioritize comfort, absorbing bumps and imperfections in the road surface effectively. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) is standard, enhancing safety and control during emergency braking situations. The electric steering system provides light and precise steering feel, making it easy to maneuver in urban environments. The vehicle’s relatively low center of gravity, thanks to the underfloor battery pack, contributes to improved stability and handling.

Market Reception & Comparison

The BYD Song Pro DM-i 1.5 has been well-received in the Chinese market, where it competes with other popular PHEV SUVs such as the Haval H6 DM-i and the Geely Boyue Pro DM-i. Critics have praised its fuel efficiency, smooth driving experience, and advanced technology. Compared to the standard gasoline-powered Song Pro, the DM-i variant offers significantly better fuel economy and a quieter, more refined driving experience. Compared to higher-output DM-i versions, it offers a more affordable entry point into the plug-in hybrid market, albeit with slightly less performance. Reliability reports have been generally positive, with BYD’s battery technology proving to be durable and long-lasting.

Legacy

The BYD Song Pro DM-i 1.5 represents a pivotal model in BYD’s transition towards becoming a leading global electric vehicle manufacturer. Its success in the Chinese market has demonstrated the viability of the DM-i technology and paved the way for further expansion of BYD’s plug-in hybrid lineup. The LiFePO4 battery technology used in this model is known for its safety and longevity, contributing to the vehicle’s long-term reliability. On the used car market, the Song Pro DM-i 1.5 remains a popular choice, particularly among buyers seeking a fuel-efficient and technologically advanced SUV. Its continued demand reflects the growing awareness of the benefits of plug-in hybrid technology and BYD’s reputation for quality and innovation.
