Please note that trim names, specifications and prices reflect a compiled dataset (October 2026). BYD Automotive Australia may update variants, so every figure must be confirmed with an authorised BYD dealer or the official BYD Australia website.

For all official service requirements, refer to the official owner’s manual. High-voltage systems present a serious hazard and must never be opened or tampered with by owners. For questions regarding BYD SEALION 6 order, delivery, and availability in Australia, contact the distributor directly.

Electric Motor Specifications

The Essential and Dynamic variants are front-wheel drive and feature a front-mounted permanent magnet synchronous motor producing 145 kW and 300 Nm. These models pair the electric motor with the 1.5 litre Xiaoyun petrol engine, which contributes 72 kW and 122 Nm. The official maximum combined system power for these front-wheel drive variants is 160 kW, subject to manufacturer specifications.

Comparing the BYD SEALION 6 Dynamic FWD against the Premium AWD models reveals a more powerful dual-motor arrangement. Premium variants feature a front permanent magnet synchronous motor delivering 150 kW and 300 Nm, together with a rear permanent magnet synchronous motor providing 120 kW and 250 Nm. The Premium variants are paired with the 1.5 Ti turbo-charged Xiaoyun engine producing 96 kW and 220 Nm. Maximum combined power reaches 238 kW on the Premium Standard Range and 253 kW on the Premium Extended Range. All output figures are subject to manufacturer specifications and should be confirmed with an authorised BYD dealer.

Variant	Front Motor	Rear Motor	Engine	Combined Power
Essential / Dynamic (FWD)	145 kW / 300 Nm	—	72 kW / 122 Nm	160 kW
Premium (AWD)	150 kW / 300 Nm	120 kW / 250 Nm	96 kW / 220 Nm	238–253 kW

High-Voltage System and Inverter

The drive motors receive power from the high-voltage BYD Blade Battery via the inverter and motor controller. The BYD SEALION 6 18.3 kWh Blade Battery is fitted to the Essential and Premium Standard Range variants, with pure electric range of 92 km (Essential) and 81 km (Premium Standard Range) on the NEDC cycle. The Dynamic and Premium Extended Range variants use a 26.6 kWh battery, enabling electric range of 140 km and 128 km respectively. These figures are based on ADR 81/02 test conditions and may differ in real-world use.

The inverter converts direct current from the battery into alternating current for the traction motors, and the system incorporates regenerative braking. High-voltage orange cables and the e-motor controller must not be touched or opened by owners under any circumstances. Any diagnosis or work on the inverter or high-voltage circuitry must be performed by an authorised BYD dealer or qualified high-voltage technician.

Drive Unit Noise and Vibration

If unusual noise or vibration symptoms are noticed while driving the BYD SEALION 6, these should be assessed professionally without delay. Symptoms such as whining, humming, or knocking noises felt through the floor or steering wheel may relate to the drive unit or associated components and warrant professional diagnosis.

Because the drive unit assembly involves high-voltage components and precision-engineered parts, owners should not attempt disassembly or self-diagnosis beyond noting the circumstances in which the symptom occurs (for example, at a particular speed, during acceleration, or during deceleration with regenerative braking active). Any inspection, diagnosis, or component replacement must be carried out by an authorised BYD dealer. Confirm with BYD Automotive Australia if a symptom persists after a dealer assessment.

Frequently Asked Questions

What powers the electric drive motors?

The traction motors draw electrical power from the high-voltage BYD Blade Battery. Depending on the variant, battery capacity is either 18.3 kWh or 26.6 kWh. When the battery charge is low, the petrol engine supplements or takes over drive duties as managed by the DM-i system.

What does the drive unit and power battery warranty cover?

The BYD Warranty and Service Handbook covers the drive motor and drive motor controller for 8 years or 160,000 km, whichever comes first, with a guarantee of at least 70% battery capacity retention. The new vehicle warranty is 6 years or 150,000 km. Full details are available at https://bydautomotive.com.au/service-and-warranty.

What should I do if I notice vibration or unusual noise from the drive unit?

If vibration or noise symptoms develop, note when they occur — for example, during acceleration, at a steady speed, or under regenerative braking — and take the vehicle to an authorised BYD dealer for diagnosis. Do not attempt to inspect or disassemble the drive unit assembly.

Does the SEALION 6 have a rear motor on all variants?

No. The Essential and Dynamic variants are front-wheel drive and have a single front motor. Only the Premium variants (all-wheel drive) are fitted with both a front and rear permanent magnet synchronous motor. Confirm the exact specification of any particular variant with an authorised BYD dealer or via the official BYD Australia website.
