The BYD Qin Pro II DM 1.5T (303 Hp) Plug-in Hybrid DCT is a compact sedan produced by the Chinese automaker BYD from September 2018 to May 2020. Representing a significant step forward in BYD’s “Dual Mode” technology, this variant combined a turbocharged gasoline engine with an electric motor and a relatively large battery pack for its time, offering both all-electric driving capability and extended range through hybrid operation. It was positioned as a mid-range offering within the Qin Pro II lineup, bridging the gap between more basic gasoline-only models and potentially higher-trim, longer-range plug-in hybrid options. The Qin Pro II DM aimed to appeal to consumers seeking fuel efficiency and reduced emissions without sacrificing performance or practicality, particularly within the rapidly growing Chinese automotive market.

Powertrain & Engine Architecture
The Qin Pro II DM 1.5T utilizes a plug-in hybrid powertrain centered around BYD’s 1.5-liter turbocharged four-cylinder gasoline engine (BYD476ZQA). This engine produces 154 horsepower at 5200 rpm and 240 Nm (177 lb-ft) of torque between 1750 and 3500 rpm. The engine features direct fuel injection and a dual overhead camshaft (DOHC) valvetrain, maximizing efficiency and power output. It’s paired with a 150 horsepower electric motor, delivering an additional 250 Nm (184 lb-ft) of torque. The combined system output reaches 303 horsepower and 490 Nm (361 lb-ft) of torque. A 14.4 kWh lithium nickel manganese cobalt oxide (Li-NMC) battery pack, positioned under the floor, provides all-electric range of up to 82 kilometers (51 miles) based on the CLTC (China Light-Duty Vehicle Test Cycle) standard. The powertrain is managed by a 6-speed dual-clutch transmission (DCT), chosen for its quick shifts and efficiency. The system allows for operation in several modes: pure electric, hybrid, and engine-only, automatically switching between them based on driving conditions and battery charge level.
Driving Characteristics
The 1.5T DM powertrain delivers a surprisingly brisk driving experience. The instant torque from the electric motor provides strong acceleration off the line, contributing to a 0-60 mph time of around 5.6 seconds. In hybrid mode, the engine and motor work in concert, offering smooth and responsive power delivery. The DCT transmission provides quick and precise gear changes, enhancing the overall driving experience. Compared to the standard gasoline-powered Qin Pro II models, the DM variant offers significantly improved acceleration and responsiveness. While the electric motor provides silent operation in EV mode, the 1.5T engine is relatively refined for a turbocharged unit. The added weight of the battery pack does slightly impact handling compared to lighter models, but the suspension is tuned to provide a comfortable ride without excessive body roll.
Equipment & Trim Levels
The Qin Pro II DM 1.5T typically came well-equipped, reflecting its mid-range positioning. Standard features generally included automatic climate control, a touchscreen infotainment system with smartphone connectivity, power windows and locks, and a rearview camera. Higher trim levels added features such as leather upholstery, a panoramic sunroof, and advanced driver-assistance systems (ADAS) like adaptive cruise control and lane departure warning. Interior design was modern and functional, with a focus on user-friendliness. The dashboard layout was clean and uncluttered, with intuitive controls. Optional extras often included upgraded sound systems and various cosmetic enhancements.
Chassis & Braking
The Qin Pro II DM 1.5T utilizes a front-wheel-drive layout. The front suspension employs an independent McPherson strut design, while the rear suspension features a torsion beam setup. This configuration balances ride comfort and handling characteristics. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) is standard. The steering system is an electric power steering (EPS) rack and pinion, providing light and precise steering feel. Typical tire sizes ranged from 225/60 R16 to 215/55 R17, depending on the trim level.
Market Reception & Comparison
The BYD Qin Pro II DM 1.5T was generally well-received in the Chinese market, where demand for plug-in hybrid vehicles was strong. Critics praised its combination of performance, fuel efficiency, and all-electric range. Compared to other plug-in hybrid sedans in its class, the Qin Pro II DM offered a competitive price point and a relatively spacious interior. Fuel economy in hybrid mode was impressive, and the all-electric range was sufficient for many daily commutes. Reliability reports were generally positive, although long-term durability data is still emerging. Compared to the gasoline-only Qin Pro II models, the DM variant commanded a premium price, but the added features and fuel savings often justified the cost for environmentally conscious buyers.
Legacy
The BYD Qin Pro II DM 1.5T played a significant role in establishing BYD as a leader in the Chinese plug-in hybrid market. It demonstrated the viability of combining a gasoline engine with electric power to deliver both efficiency and performance. The powertrain technology developed for the Qin Pro II DM has been further refined and implemented in subsequent BYD models. On the used car market, the Qin Pro II DM 1.5T remains a popular choice for buyers seeking an affordable and fuel-efficient plug-in hybrid sedan. The longevity of the battery pack is a key consideration for potential buyers, but BYD’s battery technology has proven to be relatively durable. As the automotive industry transitions towards electrification, the Qin Pro II DM 1.5T represents an important stepping stone in the development of sustainable transportation.
