Porsche Cayenne Electric vs Subaru Solterra

Side-by-Side Specs

Charging Speed

The Porsche Cayenne Electric has the higher published DC charging figure at 270 kW, which is roughly 80% higher than the Subaru Solterra at 150 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, which is 6 minutes quicker than the Subaru Solterra at 30 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Porsche Cayenne Electric has a WLTP rated range of approximately 610 km, which is roughly 195 km more than the Subaru Solterra at approximately 415 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 Subaru Solterra consumes 200 Wh/km, compared to 208 Wh/km for the Porsche Cayenne Electric. That means the Subaru Solterra 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 Subaru Solterra has approximately 69 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) and the shorter published charge time at approximately 24 minutes. 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 6.6 kW for the Subaru Solterra. 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.

If you mostly charge at home or at work and care more about daily driving costs, the Subaru Solterra is the more efficient choice at 200 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Porsche Cayenne Electric has a WLTP rated range of approximately 610 km, which is roughly 195 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
