Introduction
The BYD Song Pro DM 1.5T (473 Hp) 4WD DCT, launched in July 2019, represents a significant advancement in BYD’s Dual Mode (DM) technology. Built on the Song Pro platform, it’s a compact SUV designed to cater to the growing demand for fuel-efficient and technologically advanced vehicles in the Chinese market. The “DM” designation signifies its plug-in hybrid nature, allowing for both all-electric driving and combined gasoline-electric operation. The 1.5T variant, with its 473 horsepower combined output, sits at the top of the Song Pro DM range, offering a performance-oriented option alongside more economically focused trims. It was produced until August 2022, with updates and revisions occurring throughout its production run.
Powertrain & Engine Architecture
The heart of the Song Pro DM 1.5T is its sophisticated powertrain. It combines a 1.5-liter turbocharged four-cylinder gasoline engine (BYD476ZQB) with two electric motors – one powering the front wheels and another driving the rear axle, providing all-wheel drive capability. The gasoline engine produces 160 horsepower at 5200 rpm and 245 Nm (180.7 lb-ft) of torque at 4000 rpm. It utilizes direct fuel injection and a turbocharger with an intercooler to enhance efficiency and power output. The electric motors, utilizing synchronous technology, contribute a combined 313 horsepower and 530 Nm (390 lb-ft) of torque. The total system output reaches an impressive 473 horsepower and 775 Nm (571.61 lb-ft) of torque. The vehicle employs a 6-speed dual-clutch transmission (DCT) to manage power delivery. The 15.7 kWh lithium iron phosphate (LiFePO4) battery pack, positioned under the floor, provides an all-electric range of 81 kilometers (50.33 miles).
Driving Characteristics
The Song Pro DM 1.5T delivers a surprisingly dynamic driving experience for a plug-in hybrid SUV. The dual-motor all-wheel-drive system provides excellent traction and stability, particularly in adverse weather conditions. The combined power output results in brisk acceleration, with a 0-100 km/h (0-62 mph) time of just 4.7 seconds. In electric mode, the vehicle offers smooth and quiet operation, ideal for city driving. When the gasoline engine engages, the transition is generally seamless. The DCT transmission provides quick and precise gear changes, contributing to the sporty feel. Compared to lower-powered Song Pro DM variants, the 1.5T offers significantly more responsive acceleration and a more engaging driving experience. The gear ratios are tuned to balance performance and efficiency, prioritizing low-end torque for everyday driving and higher-end power for overtaking maneuvers.
Equipment & Trim Levels
The Song Pro DM 1.5T typically came well-equipped, reflecting its position as a premium trim level. Standard features often included leather upholstery, a large touchscreen infotainment system with navigation, a panoramic sunroof, automatic climate control, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane departure warning, and automatic emergency braking. Optional extras could include upgraded sound systems, ventilated front seats, and a 360-degree camera system. Interior design focused on a modern aesthetic with a minimalist dashboard layout and high-quality materials. The dashboard configuration typically featured a digital instrument cluster and a centrally mounted touchscreen display.
Chassis & Braking
The Song Pro DM 1.5T utilizes an independent suspension system – McPherson struts at the front and a multi-link setup at the rear – providing a comfortable ride and good handling characteristics. The suspension is tuned to balance ride comfort with body control. Braking duties are handled by ventilated discs at the front and solid discs at the rear, coupled with an anti-lock braking system (ABS) and electronic brake-force distribution (EBD). The electric motors also contribute to regenerative braking, helping to recapture energy and extend the vehicle’s range. The steering system is an electric power steering (EPS) setup, offering light and precise steering feel.
Market Reception & Comparison
The BYD Song Pro DM 1.5T was generally well-received in the Chinese market, praised for its performance, fuel efficiency, and advanced technology. Critics highlighted its impressive acceleration and comfortable ride. Compared to other plug-in hybrid SUVs in its class, the Song Pro DM 1.5T offered a compelling combination of power and efficiency. While some reviewers noted the slightly firm ride quality, the overall consensus was positive. Compared to the standard gasoline-powered Song Pro models, the DM 1.5T commanded a higher price premium, reflecting its more advanced powertrain and features. Compared to lower-powered DM variants, the 1.5T appealed to buyers prioritizing performance and all-wheel-drive capability.
Legacy
The BYD Song Pro DM 1.5T played a crucial role in establishing BYD as a leader in the Chinese new energy vehicle (NEV) market. Its advanced plug-in hybrid technology and impressive performance helped to demonstrate the potential of electric and hybrid powertrains. While the specific 1.5T variant is no longer in production, its technology and design elements have influenced subsequent BYD models. On the used car market, the Song Pro DM 1.5T remains a popular choice, particularly among buyers seeking a well-equipped and fuel-efficient SUV with a proven track record. The LiFePO4 battery technology is known for its durability and safety, contributing to the long-term reliability of the powertrain. However, as with any used vehicle, potential buyers should carefully inspect the battery health and overall condition before making a purchase.
