📖BYD Tang II: sophisticated full-size SUV bridging international EV and hybrid markets

BYD Tang II (2018-2021)

The second-generation Tang elevated BYD's flagship SUV with striking 'Dragon Face' design, seven-seat family luxury and world-class powertrain engineering in both PHEV and pure EV formats. Keeping this substantial vehicle in prime condition calls for disciplined BYD Tang maintenance, tailored to the specific powertrain installed.

PHEV models feature a 2.0-litre turbo engine mated to a six-speed dual-clutch gearbox and electric drive motors, while EV editions boast an 82.8 kWh battery pack driving single- or dual-motor setups via a dedicated reduction gearbox. High thermal loads are controlled by an advanced multi-zone cooling system managing both high-voltage electronics and cabin climate.

When inspecting a used Tang II, check tyre wear patterns across all four 20- or 22-inch wheels, as heavy vehicle weight accelerates inner shoulder wear. Verify smooth hybrid mode transitions on PHEVs, test rapid DC charging speeds on EV editions, and inspect rear suspension bushes for movement over bumpy roads.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Commanding road presence with striking design and a luxurious, whisper-quiet seven-seat cabin.
  • Versatile choice between high-performance plug-in hybrid and long-range pure electric drivetrains.
  • Potent all-wheel-drive acceleration combined with reassuring high-speed motorway stability.

Chronic weak spots

Keep an eye on
  • Tyre wear rates: large 20- to 22-inch tyres wear rapidly under heavy electric acceleration; check alignment.
  • PHEV dual-clutch transmission: ensure smooth gear transitions and verify transmission fluid changes.
  • High-voltage cooling loop: monitor coolant levels and pump operation to ensure battery temperatures remain optimal.
  • Auxiliary 12 V battery health: test low-voltage battery annually to prevent waking module faults.

Critical deadlines

Do not miss
  • Engine oil service (PHEV models): renew fully synthetic engine oil every 7,500 to 10,000 km or 12 months.
  • Brake fluid replacement: drain and flush DOT 4 hydraulic fluid every 40,000 km or 24 months.
  • Gearbox and reduction fluid service: inspect transmission oil at 40,000 km; renew fluid at 60,000 km.
  • Cooling system flush: replace high-voltage and engine coolant loops every 40,000 km or 24 months.

Frequently asked questions about BYD Tang II

Is servicing the same on every Tang II version?▾
No. The Tang II is available as petrol/diesel, hybrid or electric depending on the version. The jobs differ by powertrain, especially oil change and timing belt on combustion engines, and battery/electrical-system checks on EVs.
Which service markers apply to an electric Tang II?▾
On fully electric versions, plan an electrical-system and traction-battery check around 15,000 km / 1 year, and battery coolant around 120,000 km / 10 years (always confirm with the manufacturer).
What are the common problems on the Tang II?▾
Tang II owners should especially watch: Tyre wear rates: large 20- to 22-inch tyres wear rapidly under heavy electric acceleration; check alignment. PHEV dual-clutch transmission: ensure smooth gear transitions and verify transmission fluid changes. Garajo includes these watch points so you can act early.
How much does it cost to service a BYD Tang II?▾
The service budget for a BYD Tang II sits about 32% above the market average (premium positioning). Allow about 355 € for a full service, for example. Garajo estimates your budget by powertrain and tracks what you actually spend, for free.
Which BYD Tang II powertrain is best for town use?▾
BYD Tang II mix: hybrid : 1 version ; electric : 1 version. For mostly urban use, prefer electric versions first, then hybrids (full hybrid / mild hybrid) to keep consumption down in dense traffic.
Which BYD Tang II powertrain should you choose if you mostly drive on the motorway?▾
BYD Tang II mix: hybrid : 1 version ; electric : 1 version. For frequent motorway use, a plug-in hybrid still makes sense if you charge regularly in town; otherwise an equivalent petrol/diesel version is often more coherent.
