Side-by-Side Specs
| Spec | Porsche Cayenne Electric | Tesla Model Y |
|---|---|---|
| Battery (approx.) | ~108 kWh | ~75 kWh |
| WLTP range (rated) | ~610 km | ~586 km |
| Efficiency (approx.) | ~208 Wh/km | ~165 Wh/km |
| Max DC charging | up to 270 kW | up to 250 kW |
| 10-80% charge time (approx.) | ~24 min | ~27 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Porsche Cayenne Electric has a peak DC charging speed of 270 kW, which is roughly 8% faster than the Tesla Model Y at 250 kW. In practice, peak speed 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 10-80% charge (the most common DC fast charging scenario), the Porsche Cayenne Electric finishes in about 24 minutes, which is 3 minutes quicker than the Tesla Model Y at 27 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 24 km more than the Tesla Model Y at approximately 586 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 Tesla Model Y consumes 165 Wh/km, compared to 208 Wh/km for the Porsche Cayenne Electric. That means the Tesla Model Y 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 Tesla Model Y has approximately 75 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the Porsche Cayenne Electric wins on both peak power (up to 270 kW) and time at the plug (approximately 24 minutes from 10-80%). For long road trips with multiple charging stops, that faster turnaround makes a real difference.
Both cars support 11 kW AC charging, so home and workplace charging speeds will be similar.
If you mostly charge at home or at work and care more about daily driving costs, the Tesla Model Y is the more efficient choice at 165 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 24 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.

From Finn, engineer: Charging specs alone do not tell the full story. Real-world charging speed depends on battery temperature, state of charge, and the charger itself. These comparisons use manufacturer-published data. Approximate values only.
