Audi A6 Sportback e-tron vs BMW i4 eDrive35

Side-by-Side Specs

Charging Speed

The Audi A6 Sportback e-tron has a peak DC charging speed of 270 kW, which is roughly 50% faster than the BMW i4 eDrive35 at 180 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 A6 Sportback e-tron finishes in about 21 minutes, which is 5 minutes quicker than the BMW i4 eDrive35 at 26 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 720 km, which is roughly 220 km more than the BMW i4 eDrive35 at approximately 500 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 i4 eDrive35 consumes 154 Wh/km, compared to 158 Wh/km for the Audi A6 Sportback e-tron. That means the BMW i4 eDrive35 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 95 kWh of useable battery , while the BMW i4 eDrive35 has approximately 67.1 kWh.

Which One Should You Choose?

If fast charging speed is your priority, the Audi A6 Sportback e-tron wins on both peak power (up to 270 kW) and time at the plug (approximately 21 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 i4 eDrive35 is the more efficient choice at 154 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 720 km, which is roughly 220 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
