Audi A6 Sportback e-tron vs Porsche Taycan

Side-by-Side Specs

Charging Speed

The Porsche Taycan has a peak DC charging speed of 322 kW, which is roughly 19% faster than the Audi A6 Sportback e-tron at 270 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 Taycan finishes in about 16 minutes, which is 5 minutes quicker than the Audi A6 Sportback e-tron at 21 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 130 km more than the Porsche Taycan at approximately 590 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 A6 Sportback e-tron consumes 158 Wh/km, compared to 169 Wh/km for the Porsche Taycan. That means the Audi A6 Sportback e-tron 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 Porsche Taycan has approximately 97 kWh.

Which One Should You Choose?

If fast charging speed is your priority, the Porsche Taycan wins on both peak power (up to 322 kW) and time at the plug (approximately 16 minutes from 10-80%). For long road trips with multiple charging stops, that faster turnaround makes a real difference.

For AC charging (home wallboxes, workplace chargers, and public street chargers), the Porsche Taycan supports up to 22 kW, compared to 11 kW for the Audi A6 Sportback e-tron. In Europe, many public chargers are 22 kW AC, so this difference can mean charging roughly twice as fast at those locations.

If you mostly charge at home or at work and care more about daily driving costs, the Audi A6 Sportback e-tron is the more efficient choice at 158 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 130 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
