BYD SEALION 7 vs Porsche Cayenne Electric

Side-by-Side Specs

Charging Speed

The Porsche Cayenne Electric has the higher published DC charging figure at 270 kW, which is roughly 17% higher than the BYD SEALION 7 at 230 kW. In practice, that figure only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.

For the published fast-charge window, the Porsche Cayenne Electric is listed at about 24 minutes, roughly matching the BYD SEALION 7. In this case, the headline kW number should not drive the decision by itself.

Range and Efficiency

The Porsche Cayenne Electric has a WLTP rated range of approximately 610 km, which is roughly 108 km more than the BYD SEALION 7 at approximately 502 km. WLTP is a standardized lab test. Expect your actual range to be lower, varying with speed, weather, terrain, and driving style.

Efficiency matters more than battery size for daily driving costs. The Porsche Cayenne Electric consumes 208 Wh/km, compared to 208 Wh/km for the BYD SEALION 7. That means the Porsche Cayenne Electric uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.

A more efficient car does not always mean more range. Battery size plays a role too. The Porsche Cayenne Electric has approximately 108 kWh of useable battery , while the BYD SEALION 7 has approximately 91.3 kWh.

Which One Should You Choose?

If fast charging is your priority, the Porsche Cayenne Electric has the higher published DC figure (up to 270 kW), but both cars are listed at approximately 24 minutes for the published fast-charge window. For long road trips, published stop time matters more than the headline kW number alone.

For AC charging (home wallboxes, workplace chargers, and public street chargers), the Porsche Cayenne Electric supports up to 11 kW (22 kW optional), compared to up to 11 kW for the BYD SEALION 7. In Europe, many public chargers are 22 kW AC, so this difference can matter at those locations if the higher AC figure is fitted on the car you buy.

Both cars have similar efficiency at 208 Wh/km, so daily charging costs should be comparable.

For maximum range between charges, the Porsche Cayenne Electric has a WLTP rated range of approximately 610 km, which is roughly 108 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
