Side-by-Side Specs
| Spec | Audi e-tron GT | Rolls-Royce Spectre |
|---|---|---|
| Battery (approx.) | ~83.7 kWh | ~102 kWh |
| WLTP range (rated) | ~488 km | ~530 km |
| Efficiency (approx.) | ~202 Wh/km | ~219 Wh/km |
| Max DC charging | up to 270 kW | up to 195 kW |
| 10-80% charge time (approx.) | ~18 min | ~34 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Audi e-tron GT has a peak DC charging speed of 270 kW, which is roughly 38% faster than the Rolls-Royce Spectre at 195 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 Audi e-tron GT finishes in about 18 minutes, which is 16 minutes quicker than the Rolls-Royce Spectre at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Rolls-Royce Spectre has a WLTP rated range of approximately 530 km, which is roughly 42 km more than the Audi e-tron GT at approximately 488 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 Audi e-tron GT consumes 202 Wh/km, compared to 219 Wh/km for the Rolls-Royce Spectre. That means the Audi e-tron GT 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 Rolls-Royce Spectre has approximately 102 kWh of useable battery , while the Audi e-tron GT has approximately 83.7 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the Audi e-tron GT wins on both peak power (up to 270 kW) and time at the plug (approximately 18 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 Audi e-tron GT is the more efficient choice at 202 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Rolls-Royce Spectre has a WLTP rated range of approximately 530 km, which is roughly 42 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.
