The Audi A6 Sportback E-Tron has set a Guinness World Record for production cars after covering 831 miles (1,338 km) on a single charge. Polish rally driver Miko Marczyk completed the run on public roads, traveling about 72 percent farther than the model’s official WLTP range of up to 777 km (483 miles).

The record attempt began at 1:55 AM on September 11 in Poland. Marczyk drove along the Vistula, passing through Krakow, Sandomierz, Warsaw, Torun, and Grudziadz before reaching Hel on the Baltic Sea. He then retraced much of the route, with the Audi finally running out of battery somewhere between Torun and Ciechocinek more than 45 hours after setting off.

How the Audi reached 831 miles

Marczyk averaged just 7.09 kWh/100 km during the drive. That is less than half the Audi A6 Sportback E-Tron’s official combined consumption figure, highlighting how dramatically driving conditions and technique can change real-world EV efficiency.

The car remained on public roads throughout the attempt and dealt with regular traffic, including rush-hour conditions. Average temperatures were around 15 degrees Celsius (59 degrees Fahrenheit), with the temperature falling as low as 7°C (45°F).

Marczyk’s approach focused on minimizing energy use. He said drivers should understand the car, use regenerative braking intelligently, maintain correct tire pressures, anticipate traffic, and avoid unnecessary acceleration and braking. Those methods are far removed from ordinary driving, but they helped stretch every kilowatt-hour during the record run.

Aerodynamics and battery capacity

The Audi also brought strong efficiency fundamentals to the challenge. Its Sportback body has a 0.21 drag coefficient, making it Audi’s most aerodynamic production car. The vehicle uses a battery with a net capacity of 94.9 kWh, while its regenerative braking system can deliver up to 220 kW.

Audi says around 95 percent of everyday braking events can be handled through recuperation. That capability, the car’s streamlined shape, and Marczyk’s careful driving combined to produce the record result.

What the record means for everyday range

The 831-mile figure is not an indication that every A6 Sportback E-Tron owner can expect that distance in normal use. Marczyk spent more than 45 hours driving and deliberately optimized speed, acceleration, braking, and route conditions. The car’s official WLTP rating remains up to 777 km (483 miles).

Even with those limitations, the attempt demonstrates the efficiency potential of a modern electric liftback. It also gives the A6 Sportback E-Tron another headline achievement alongside its low-drag body, large battery, and high-power energy recovery system.

This is Marczyk’s second major efficiency record. In 2025, he drove a Skoda Superb diesel 2,831 km (1,759 miles) on one tank, averaging 2.61 liters per 100 kilometers (90.1 mpg).
