BYD INNOVATION IN PHEV TECHNOLOGY
BYD, the world’s leading manufacturer of new energy vehicles (EV & PHEV), is at the forefront of battery-powered automotive innovation, with a longstanding reputation for pioneering development. BYD introduces game-changing technology with the UK entry of the new BYD SEAL U DM-i, bringing to market an exceptional vehicle that pushes the boundaries in the plug-in hybrid SUV class.
The BYD SEAL U DM-i marks a new era in intelligent Plug-in Hybrid Electric Vehicles. It benefits from BYD’s cutting-edge Super DM (Dual Mode) Technology that prioritises electric with ultra-low fuel consumption and superb energy efficiency, making it both an eco-friendly and economical option.
BYD Super DM Technology – setting a new benchmark for PHEV efficiency
Super DM Technology, developed in-house by BYD, incorporates a highly efficient system that uses electric-based hybrid architecture. The technology is powered by an electric motor in 90% of driving conditions, therefore minimising reliance on petrol – reducing fuel costs and carbon emissions. It further benefits from excellent energy efficiency, making it an economical solution for motorists while being practical for both daily needs and long worry-free journeys. BYD Super DM Technology also produces a quiet, smooth ride that feels more like that of a pure-electric vehicle, with powerful acceleration and performance to match. It effortlessly adapts to different driving conditions.
The drivetrain consists of three main components that work seamlessly together: the Electric Hybrid System, the Xiaoyun Hybrid Engine and the Blade Battery.
This electric-based hybrid architecture differs from most other PHEV technologies as it only uses the internal combustion engine for assistance. This means the drivetrain prioritises electric power, therefore only having minimal reliance on fuel, making it kinder to the environment.
Intelligent Electric Hybrid System
The Electric Hybrid System (EHS) is a highly integrated powertrain that incorporates high-speed dual motors, dual controllers and advanced oil-cooling technology to increase motor power density and efficiency. The EHS utilises high-speed dual motors with a maximum speed of up to 15,000 rpm. With two separate functions, the P1 motor generates the power and the P3 motor drives the wheels. Furthermore, the electric motors use innovative hairpin technology which significantly improves heat dissipation performance. Peak efficiency can be as much as 97%, remaining stable above 90% for most of the time. The EHS also benefits from oil cooling technology that directly cools the heat source, enhancing dissipation capabilities, increasing motor power density to a maximum of 5.5 kW/kg. Finally, the highly Integrated Dual Motor Controller (IGBT) elevates the overall electronic control efficiency up to 98.9%.
A significant feature of the electric hybrid system is its ability to intelligently switch between the modes to prioritize electric propulsion whenever possible, providing an efficient and more environmentally friendly driving experience.
When the battery is fully charged and switched to EV mode, the vehicle becomes pure-electric, and when State of Charge (SoC) is low, it transforms into an ultra-low fuel consumption hybrid vehicle alleviating concerns about electric range. When travelling in urban areas, the electric motor powers the vehicle for most of the time.
3 Driving Modes:
Pure EV mode: quiet, smooth, responsive electric driving where the wheels are 100% driven by the electric motor, with industry leading NVH (Noise Vibration Harshness).
HEV mode: urban cycle provides high fuel economy and high performance. When the battery falls below the set state of charge, the combustion engine automatically engages as a generator and charges the battery with the electric motor driving the wheels.
HEV Parallel mode: the wheels are driven by both the electric motor and the combustion engine realising high power performance and good fuel efficiency. This mode produces fast, responsive acceleration when you need maximum power such as when overtaking on motorways.
With regenerative technology, the battery continues to charge while driving regardless of the selected mode.
Specially Developed Xiaoyun Petrol Engine
The BYD SEAL U DM-i utilises a dedicated ‘Xiaoyun’ petrol engine producing world-leading thermal efficiency, which has been specifically developed in-house for the BYD Super DM Technology plug-in hybrid drivetrain. There are two engine variants.

2Power consumption is calculated in accordance with Regulation (EU) 2017-1151.
3The WLTP range and consumption values are obtained under standard EU test conditions, according to the uniform provisions concerning the approval of motor vehicles with regard to the emissions based on the new World Harmonized Light Vehicle Test Procedure (WLTP). The actual range and energy consumption figures may vary due to a number of factors such as weather conditions, traffic situation, vehicle load and driving behaviours.
4Charging times and charging speed may vary due to different factors such as battery temperature, specs of charging infrastructure, state of charge. A CCS2 DC charger with the output higher than 100kW and the voltage higher than 500V, as well as the suitable ambient temperature (25℃) are required to achieve the maximum charging speed.
5 The AC charging power can up to 11kW while the actual charging power might be limited at low SOC.
