<![CDATA[BYD Sealion 7 Excellence AWD UK Winter Motorway Range Test (M1/M6 at 3°C) & 230kW DC Rapid Charging Curve]]>Just wrapped up my first proper cold-weather motorway run in the 2025 BYD Sealion 7 Excellence AWD (91.3 kWh Blade Battery, 800V-class architecture with 230kW DC charging) from Cambridge up to Manchester and back in 2°C to 4°C wet UK conditions, and wanted to share unfiltered real-world numbers.

BYD Sealion 7 Excellence AWD UK Winter Motorway Range Test (M1/M6 at 3°C) & 230kW DC Rapid Charging Curve

Test Conditions

  • Vehicle: 2025 BYD Sealion 7 Excellence AWD on factory 20" Michelin Pilot Sport EV tyres (39 PSI all round)
  • Weather: 3°C ambient, wet roads, light headwind going north on the M1/M6
  • Cabin: Heat pump AC set to 21°C Auto, heated seats level 1, pre-conditioned on the 7kW wallbox before departure.

Real-World Range & Efficiency (91.3 kWh Usable)

  • Steady 70 mph (GPS) in 3°C wet: 2.8 mi/kWh (22.2 kWh/100km) → ~255 miles (410 km) real 100%–0% winter motorway range (or ~205 miles comfortable 100% down to 18% leg).
  • Mixed A-roads & 50 mph average speed cameras: 3.4 mi/kWh (18.3 kWh/100km) → ~310 miles (500 km).
  • Summer comparison (18°C): Last month I was getting 3.6 mi/kWh comfortably on the same route (~328 miles real range).

230kW DC Rapid Charging Curve (Ionity 350kW Charger)

Plugged in at 11% SOC after using the built-in SatNav charger routing (which triggered battery pre-heating 25 mins prior):

  • 11% to 35%: Held a rock-solid 224 kW – 231 kW!
  • 50% SOC: Still pulling 178 kW
  • 10% to 80% total time: 23 minutes 40 seconds (beat BYD's official 24-minute claim!).

I test-drove a Model Y in Bristol last week and the rear suspension crashed over every pothole.

My 2024 Seal Excellence caps out around 150kW peak (and closer to 95kW in winter if the pack isn't warm). Moving the Sealion 7 Excellence to the 91.3 kWh pack with 230kW peak fixes the single biggest complaint high-mileage UK drivers had.
