The Audi A6 e-tron can travel 1,338 km without needing to recharge.
Rally Europe champion Miko Marczyk set a Guinness World Record using an Audi A6 Sportback e-tron performance. With a single battery charge, he covered 1,338 kilometers, with an average consumption of 7.09 kWh per 100 km.

Normally, Miko Marczyk’s focus is on spending as little time as possible on the road. However, during his most recent trip in an Audi A6 Sportback e-tron performance, the opposite was required: less speed, more efficiency. On September 11th, the Polish rally driver set out at 1:55 a.m. to attempt a Guinness World Record, driving along the Vistula River across Poland.
The route took him through Kraków, Sandomierz, Warsaw, Toruń, and Grudziądz to Hel by the Baltic Sea, then back along the same path. But after more than 45 hours, it was finally over—exactly 1,338 kilometers in from Toruń to Ciechocinek.
Marczyk was driving in regular traffic, and according to Audi, partly through heavy commuter traffic as well, and was not allowed to refuel. The average temperature was around 15 degrees Celsius, dropping to as low as seven degrees in Grudziądz early in the morning.
The comparison with the standard range is surprising. The Audi A6 Sportback e-tron performance used in this test officially has a range of up to 777 kilometers according to WLTP standards. In this record attempt, it covered an additional 561 kilometers.
Unsurprisingly, the key lies not in a secret second battery under the trunk floor, but in the driver’s consistent efficiency. Audi reports an energy consumption of just 7.09 kWh per 100 kilometers while driving. For comparison, the usable battery capacity of 94.9 kWh alone shows how far this vehicle had to travel to achieve such low consumption compared to typical everyday use. Marczyk relied on standard efficiency tactics: maintaining a steady speed, driving predictably, minimizing unnecessary acceleration and braking, keeping tire pressure correct, and using regenerative braking effectively.
"Even for me, the result of 1,338 kilometers was a pleasant surprise," says Marczyk. The record-breaking driver attributes this to the combination of the drive system, battery, and low air resistance.
Aerodynamics prove decisive over long distances
Technically, the A6 Sportback e-tron is based on the Premium Platform Electric, or PPE. The performance variant tested features a battery with a gross capacity of 100 kWh and a net capacity of 94.9 kWh, along with an 800-volt architecture.
In such range tests, aerodynamics play a significant role. The A6 Sportback e-tron has a cW value of 0.21, making it Audi’s most aerodynamically efficient production model to date. At higher speeds, the impact of air resistance on energy consumption increases substantially. Audi states that it accounts for around 40 percent of the consumption in the WLTP cycle for this model.
In addition, there is regenerative braking. The vehicle can recover up to 220 kW of energy while decelerating. According to Audi, this allows around 95 percent of everyday braking scenarios to be handled without using the mechanical brakes.
This record should not, however, be confused with a new realistic range figure. Anyone who drives at 130 km/h on the highway in the morning, turns up the heating, and still wants 10 percent of battery charge left upon arrival will not be able to extract 1,338 kilometers from 94.9 kWh. But that’s not the point either.
Such record drives are less of a routine test and more of a technical stress test in the opposite direction. Instead of testing how much power an electric car can deliver, it examines how little energy it needs under favorable conditions. That is precisely why 7.09 kWh/100 km is more interesting than just the distance traveled: it shows what potential exists in aerodynamics, rolling resistance, regenerative braking, and driving strategy when all factors work together in the same direction.
This kind of efficiency record is nothing new for Marczyk. As early as March 2025, he drove a fourth-generation standard Skoda Superb with a 2.0-TDI engine 2,831 kilometers on a single tank of fuel. The average fuel consumption at that time was 2.6 liters per 100 kilometers. Now he has applied the same ambition to electric vehicles — instead of maximizing distance per liter of diesel, the focus this time is on every single kilowatt hour.
