Audi's A6 Sportback E-Tron now holds the Guinness World Record for production cars after covering 831 miles (1,338 km) on one charge, showing how extreme hypermiling and vehicle efficiency can push a production EV well beyond its official range.
Polish rally driver Miko Marczyk completed the attempt, averaging 7.09 kWh per 100 km over the run. The A6 Sportback E-Tron carries a WLTP range of up to 777 km (483 miles), so Marczyk managed roughly 72 percent more distance than the official figure.
The drive began at 1:55 AM on September 11 in Poland and followed the Vistula river corridor, passing Krakow, Sandomierz, Warsaw, Torun, and Grudziadz before reaching Hel on the Baltic Sea. Marczyk then turned back along much of the same route. More than 45 hours after departure, the car exhausted its battery between Torun and Ciechocinek. Ambient temperatures averaged about 15 degrees Celsius and fell to as low as 7 degrees Celsius during the attempt.
Several vehicle details help explain the result. The A6 Sportback E-Tron has a net battery capacity of 94.9 kWh and a drag coefficient of 0.21, Audi's lowest for a production model. Regenerative braking can deliver up to 220 kW, and the manufacturer states around 95 percent of everyday braking events can be handled through recuperation. Marczyk also applied classic hypermiling methods, including careful use of recuperation, precise speed management, correct tire pressures, and avoiding unnecessary acceleration and braking.
This record applies to production cars, not experimental prototypes. The overall single-charge EV distance record remains the 2,573.79 km (1,599.27 miles) run by the TUfast Eco Team's muc022 prototype in Germany in September 2023. Marczyk's achievement joins his previous efficiency record, when he drove a Skoda Superb diesel 2,831 kilometers (1,759 miles) on one tank, averaging 2.61 liters per 100 kilometers (90.1 mpg).
While the result highlights how much range can improve under optimised driving and with an aerodynamic, large-battery vehicle, it is not a typical customer outcome. The record relied on prolonged, deliberate efficiency tactics over public roads and traffic conditions, so everyday drivers should expect real-world range to be closer to official WLTP figures than to this extreme example.
