Side-by-Side Specs
| Spec | Audi e-tron GT | BMW i5 |
|---|---|---|
| Battery (approx.) | ~83.7 kWh | ~81.2 kWh |
| WLTP range (rated) | ~488 km | ~581 km |
| Efficiency (approx.) | ~202 Wh/km | ~173 Wh/km |
| Max DC charging | up to 270 kW | up to 205 kW |
| 10-80% charge time (approx.) | ~18 min | ~33 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 32% faster than the BMW i5 at 205 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 15 minutes quicker than the BMW i5 at 33 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BMW i5 has a WLTP rated range of approximately 581 km, which is roughly 93 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 BMW i5 consumes 173 Wh/km, compared to 202 Wh/km for the Audi e-tron GT. That means the BMW i5 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 BMW i5 has approximately 81.2 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 BMW i5 is the more efficient choice at 173 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BMW i5 has a WLTP rated range of approximately 581 km, which is roughly 93 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.
