Audi A6 Sportback e-tron vs BMW i7

Side-by-Side Specs

Charging Speed

The Audi A6 Sportback e-tron has the higher published DC charging figure at 269 kW, which is roughly 35% higher than the BMW i7 at 200 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 Audi A6 Sportback e-tron is listed at about 23 minutes, which is 7 minutes quicker than the BMW i7 at 30 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Audi A6 Sportback e-tron has a WLTP rated range of approximately 756 km, which is roughly 145 km more than the BMW i7 at approximately 611 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 i7 consumes 196 Wh/km, compared to 225 Wh/km for the Audi A6 Sportback e-tron. That means the BMW i7 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 Audi A6 Sportback e-tron has approximately 94.9 kWh of useable battery , while the BMW i7 has approximately 101.7 kWh.

Which One Should You Choose?

If fast charging is your priority, the Audi A6 Sportback e-tron has the higher published DC figure (up to 269 kW) and the shorter published charge time at approximately 23 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 Audi A6 Sportback e-tron supports up to 11 kW (22 kW optional), compared to up to 11 kW for the BMW i7. 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 BMW i7 is the more efficient choice at 196 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Audi A6 Sportback e-tron has a WLTP rated range of approximately 756 km, which is roughly 145 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
