BYD SEALION 6

The BYD SEALION 6 is a mid-size SUV featuring a plug-in hybrid (PHEV) powertrain. This model integrates a Xiaoyun 1.5-litre petrol engine, electric motors, and a high-voltage BYD Blade Battery to form the BYD Super Hybrid architecture. It is not a pure EV. This independent guide details the suspension layout, wheel specifications, and tyre guidance for the Australian market.

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.

Suspension Layout and Specifications

The BYD SEALION 6 utilises a front MacPherson suspension and a rear multi-link suspension. The vehicle has an overall length of 4,775 mm, a width of 1,890 mm, and a height of 1,670 mm. The wheelbase is 2,765 mm, providing the foundational footprint for the chassis. The front wheel track and rear wheel track are identical at 1,630 mm, and the vehicle has a minimum turning radius of 5.5 m.

The front MacPherson suspension supports the front of the vehicle, which houses the Xiaoyun engine and the front permanent magnet synchronous motor. The multi-link rear suspension on the BYD SEALION 6 handles ride quality across various surfaces, including country roads. The specific alignment geometries, damper rates, and spring tolerances are subject to manufacturer specifications. Any inspection or adjustment of these components should be recorded carefully.

Kerb Weight and Chassis Dynamics

Because the BYD SEALION 6 is a plug-in hybrid rather than a traditional internal combustion vehicle without electric motors, the suspension system carries substantial mass. The kerb weight varies across the four available variants. The front-wheel drive Essential Standard Range weighs 1,940 kg, while the Dynamic Extended Range weighs 1,995 kg. The all-wheel drive variants carry additional hardware, including a rear 120 kW electric motor; the Premium Standard Range has a kerb weight of 2,100 kg, and the Premium Extended Range weighs 2,160 kg.

A review of the BYD SEALION 6 Dynamic FWD versus the Premium AWD reveals how this difference in kerb weight alters the physical load on the suspension components. The gross vehicle mass (GVM) reaches 2,570 kg on the heaviest variant. Official towing capacities and ground clearance figures are not published in the standard brochure; you must confirm with BYD Automotive Australia for exact measurements prior to fitting towing accessories or planning off-road travel.

Wheels, Tyres, and Pressures

All four variants of the BYD SEALION 6 are equipped with alloy wheels and feature a uniform tyre size of 235/50 R19. The factory-fitted tyres are manufactured by Giti. Maintaining the correct tyre pressure is essential for supporting the vehicle’s mass, ensuring safety, and achieving optimum efficiency. Real-world fuel consumption may differ from the ADR 1.1 L/100 km result recorded for the Essential variant, and correct tyre inflation plays a role in these figures.

The BYD SEALION 6 features a 60 L fuel tank, which adds further weight to the chassis when full. For precise tyre inflation values and load ratings, owners must refer to the official owner’s manual. The tyre pressures must be checked when the tyres are cold, before driving.

Wheel Alignment and Servicing

Wheel alignment and balancing are necessary procedures to keep the vehicle driving straight and to ensure the tyres wear evenly over time. During alignment checks, technicians measure and adjust the geometry of the front MacPherson and rear multi-link suspension. The braking hardware, which includes front ventilated discs, front floating calipers, and rear solid discs, operates in close proximity to the suspension links.

According to the official warranty handbook, wheel alignment, balancing, and tyre replacements are items for which a charge may be made. They are not covered by the 6-year / 150,000 km new vehicle warranty. Tyres have their own coverage through the respective tyre manufacturer. For scheduled maintenance intervals, which occur every 20,000 km or 12 months, owners must consult an authorised BYD dealer.

When looking at replacement options for the 235/50 R19 tyres on the BYD SEALION 6, owners can select from various brands as long as the load and speed ratings match the original equipment. The price of the BYD SEALION 6 in Australia, including any specific driveaway price in Melbourne, Sydney, or Brisbane, does not cover these ongoing maintenance costs. Wait times for specific tyre brands can vary; checking order and delivery availability in Australia directly with a retail outlet is recommended.

Safety and High-Voltage Precautions

The powertrain features a high-voltage BYD Blade Battery, with a capacity of 18.3 kWh on Standard Range models and 26.6 kWh on Extended Range models. The DM-i super hybrid system on the BYD SEALION 6 is explained as a system relying on high-voltage components situated throughout the vehicle structure.

High-voltage orange cables must not be touched or opened by owners. Any dangerous work involving the high-voltage system, steering hardware, suspension replacement, brakes, airbags, or calibration of the DiPilot driver assistance cameras and sensors must be done by an authorised BYD dealer or qualified technician. Never attempt to follow step-by-step repair instructions found online, as improper handling of PHEV systems can result in severe injury or vehicle damage.

Bushings and Operational Sounds

Suspension bushings and linkages isolate the cabin from road imperfections. As a vehicle accumulates kilometres, suspension components flex and shift. Owners noticing any unexpected noises, knocking sounds, or changes in ride characteristics should document the symptoms neutrally. Any diagnostic work to identify worn bushings, leaking dampers, or loose mounts requires lifting the vehicle safely and inspecting the undercarriage. This process must follow official guidelines and must be performed by a qualified professional.

Frequently Asked Questions

Are tyres covered under the BYD new vehicle warranty?

No, tyres are not covered by the BYD 6-year / 150,000 km new vehicle warranty. Coverage for tyres is provided by the individual tyre manufacturer’s warranty.

How does the suspension differ between the Essential and Premium variants?

All variants use a front MacPherson suspension and a rear multi-link suspension. However, the Premium variants are all-wheel drive and have a higher kerb weight (up to 2,160 kg) due to the addition of a rear electric motor and the 1.5 Ti turbocharged engine.

What size are the factory wheels and tyres?

All variants come with alloy wheels and 235/50 R19 Giti tyres. When purchasing replacements, check the placard to ensure the correct load and speed ratings are maintained.

Can I alter the suspension to increase ground clearance?

The official brochure does not state the factory ground clearance. Modifications to the suspension are not recommended, as unauthorised modifications may void the manufacturer warranty.

Does the vehicle weight affect tyre replacement schedules?

Plug-in hybrid vehicles like the BYD SEALION 6 carry high-voltage batteries and electric motors, producing up to 300 Nm of torque at the front motor and possessing a kerb weight up to 2,160 kg. Proper alignment and tyre rotation schedules are necessary to maximise tyre life.

How does the Sealion 6 compare to other PHEVs?

When researching the BYD SEALION 6 versus the Mitsubishi Outlander PHEV in Australia, prospective buyers should review the specific dimensions, battery capacities, and kerb weights of each variant.
