2025 BYD Seal Excellence EV AWD Electricity · V3 ALM

Running a BYD Seal Excellence EV AWD is generally cheaper than its petrol or diesel equivalents, with home charging costs typically working out at around 4-5p per mile. The Seal Excellence has a sizeable battery and AWD powertrain, so real-world range will likely be in the 280-320 mile bracket depending on conditions. Public rapid charging will push that cost per mile considerably higher, so factor in your typical charging pattern.

As a pure electric vehicle registered from March 2025, this Seal sits in the lowest VED band and is exempt from road tax until 2030 (when the exemption narrows). It is also exempt from the London Congestion Charge and most Clean Air Zone charges. Insurance for the Seal Excellence AWD is likely to sit in group 40-50 due to its performance credentials and value — get quotes before committing.

Estimated annual maintenance is modest given EVs have fewer moving parts than combustion cars — budget around £150-£300 for routine items plus any tyres, plus electricity. The estimated annual running cost is £1,200-£1,800 covering charging, insurance, tax (currently zero), and maintenance.

Without any MOT history, there is no recorded evidence of component wear or failures to reference on this specific vehicle. For the BYD Seal range generally, owners have reported occasional issues with infotainment glitches, so test the rotating central screen thoroughly — check responsiveness, Bluetooth pairing, and reversing camera clarity. Inspect the 12V auxiliary battery condition, as premature failure has been reported on other Chinese EVs and can cause a no-start situation.

On the test drive, listen for any unusual noises from the electric motors, particularly on full acceleration when both axles should deploy power smoothly. Check that the regenerative braking modes operate correctly and that the one-pedal driving mode functions as expected. Inspect all four tyres for even wear — uneven wear on a near-new AWD EV can indicate alignment or suspension issues from kerbing.

Inspect the underside (using a ramp or lift if possible) for any signs of damage to the undertray or battery pack protection plate, as a low-slung saloon can be vulnerable to kerbs and speed bumps. Verify all charging cables and the granny charger are present, and check the Type 2 inlet for signs of overheating or scorching which could indicate previous charging faults. Finally, confirm all driver-assistance systems (adaptive cruise, lane keep, 360-degree cameras) calibrate and function correctly.
