BYD SEALION 6

This independent guide outlines the powertrain and fuel specifications for the BYD SEALION 6 in Australia. The information covers the plug-in hybrid (PHEV) systems, including the internal combustion engine, electric motors, and the BYD Blade Battery. Please note that trim names, specifications, and prices reflect a compiled dataset (October 2026) and that BYD Automotive Australia may update variants, so every figure must be confirmed with an authorised BYD dealer or the official BYD Australia website. Official service/warranty page: https://bydautomotive.com.au/service-and-warranty. This model operates strictly as a plug-in hybrid vehicle; BYD does not offer or authorise LPG/CNG/autogas conversions, and any aftermarket gas conversion voids the factory warranty. For any concerns, always consult an authorised BYD dealer.

Hybrid System Overview

The BYD SEALION 6 powertrain operates as a plug-in hybrid (PHEV), combining a petrol engine with electric motors and a high-voltage traction battery. The DM-i super hybrid system is built on architectures that prioritise both fuel economy and utility. The vehicle features three driving modes: Eco, Normal, and Sport. Depending on the variant, driving terrain modes are also available, including Snow on the Essential Standard Range and Dynamic Extended Range trims, and Snow, Mud, and Sand on the Premium Standard Range and Premium Extended Range trims. The exact powertrain configuration is subject to manufacturer specifications and relies on a seamless integration of the combustion engine and electric drive systems.

Engine Specifications & Output

The petrol engine fitted to the BYD SEALION 6 varies depending on the chosen trim. The Essential Standard Range and Dynamic Extended Range variants feature a Xiaoyun 1.5 litre high-efficiency engine. This engine delivers a peak power output of 72 kW and 122 Nm of torque. In contrast, the Premium Standard Range and Premium Extended Range variants utilise a Xiaoyun 1.5 Ti high-efficiency turbo-charged engine, which produces 96 kW and 220 Nm of torque. Detailed specifications for the 1.5L Xiaoyun engine can be found in official manufacturer literature. The model is equipped with a 60 L fuel tank across all trims. While the tank capacity is confirmed in the brochure, the required fuel grade is not stated. Owners must refer to the official owner’s manual for precise fluid requirements and maintenance schedules, including information related to the engine oil grade, fluid capacity, and filter replacement procedures.

Electric Motors & Drive Layout

The electric drive layout of the BYD SEALION 6 dictates its performance characteristics and driven wheels. The Essential Standard Range and Dynamic Extended Range trims feature a front-wheel-drive layout with a permanent magnet synchronous front motor, producing 145 kW and 300 Nm of torque. The maximum combined power output for these front-wheel-drive variants is 160 kW. The Premium variants employ an all-wheel-drive system, retaining a permanent magnet synchronous front motor with an increased output of 150 kW and 300 Nm, while adding a permanent magnet synchronous rear motor that generates 120 kW and 250 Nm of torque. This configuration results in a maximum combined power of 238 kW for the Premium Standard Range and 253 kW for the Premium Extended Range. The vehicle accelerates from 0-100 km/h in 8.5 seconds (Essential Standard Range), 8.9 seconds (Dynamic Extended Range), 5.9 seconds (Premium Standard Range), and 5.5 seconds (Premium Extended Range).

Battery Capacity & Charging Capabilities

Energy storage is managed by a BYD Blade Battery. The Essential Standard Range and Premium Standard Range models are equipped with an 18.3 kWh battery, whereas the Dynamic Extended Range and Premium Extended Range feature a larger 26.6 kWh capacity. Regarding pure electric driving capability, the 18.3 kWh Blade battery delivers a pure electric range of 92 km on the NEDC cycle for the Essential Standard Range variant. The Dynamic Extended Range achieves 140 km, the Premium Standard Range 81 km, and the Premium Extended Range 128 km.

For charging, all variants include an AC charging port Type 2 capable of up to 6.6 kW, supporting home AC charging via a wallbox or portable charging cable (mode 2). Additionally, the vehicle supports DC fast charging via an 18 kW CCS 2 public charger connection. The model also features a V2L function and comes with a V2L discharge adapter, allowing the vehicle to function as an appliance power supply. The traction battery warranty covers 8 years or 160,000 km, whichever occurs first, with a guarantee of at least 70% capacity retention. Always confirm with BYD Automotive Australia for complete warranty terms.

Fuel Consumption & Efficiency

Official fuel efficiency figures for the BYD SEALION 6 are based on ADR 81/02 test results. With a charged battery (SOC 25%-100% for Standard Range, 20%-100% for Extended Range), the combined fuel consumption is rated at 1.1 L/100 km for the Essential Standard Range, 0.8 L/100 km for the Dynamic Extended Range, 1.4 L/100 km for the Premium Standard Range, and 1.1 L/100 km for the Premium Extended Range. Although the ADR test result shows an impressive 1.1 L/100 km for the Essential Standard Range variant, the real-world fuel consumption may differ depending on driving conditions and battery state of charge. When the battery state of charge is low (under 25% or under 20%), fuel consumption increases to 4.72 L/100 km, 4.8 L/100 km, 5.8 L/100 km, and 5.5 L/100 km across the respective variants.

High-Voltage Safety & Maintenance

The BYD SEALION 6 incorporates high-voltage electrical systems that require specialised care. High-voltage orange cables must not be touched or opened by owners under any circumstances. All maintenance and repairs involving the high-voltage system, electric motors, traction battery, brakes, steering, or airbags must be done by an authorised BYD dealer or qualified technician. Never attempt step-by-step repair instructions found online for these critical systems. If you need to jump start the 12V auxiliary battery under the bonnet, carefully consult the correct procedures in the official documentation to ensure safety. Always refer to the official owner’s manual for complete maintenance schedules and safety guidelines.
