Audi A6 e-tron travels 1,338 km without recharging
European Rally Champion Miko Marczyk has set a Guinness World Record with an Audi A6 Sportback e-tron performance. On a single battery charge, he covered 1,338 kilometers with an average consumption of 7.09 kWh/100 km.

Normally, Miko Marczyk’s focus is on losing as little time as possible on the road. But for his latest outing in the Audi A6 Sportback e-tron Performance, the opposite was required: speed out, efficiency in. On 11 September at 1:55 AM, the Polish rally driver set off on a Guinness World Record attempt that took him along the Vistula River across Poland.
The route passed through Kraków, Sandomierz, Warsaw, Toruń and Grudziądz before reaching Hel on the Baltic coast, then returned along the same path. But after more than 45 hours, the journey finally came to an end – between Toruń and Ciechocinek, after exactly 1,338 km.
According to Audi, Marczyk drove in regular traffic, including during rush hour, and was not allowed to recharge. The average temperature was around 15 degrees Celsius, dropping to as low as seven degrees in Grudziądz in the early morning.
The comparison with the standard range is surprising. The Audi A6 Sportback e-tron Performance officially offers up to 777 km per WLTP. During the record attempt, it managed an additional 561 km.
Unsurprisingly, the key was not a secret second battery under the boot floor, but consistent efficiency on the part of the driver. Audi reports that energy consumption during the drive was just 7.09 kWh per 100 kilometres. For comparison: the usable battery capacity of 94.9 kWh alone shows how far the car was driven from typical everyday consumption. Marczyk relied on the usual efficiency levers: steady speed, anticipatory driving, minimal unnecessary acceleration and braking, correct tyre pressure, and targeted use of regenerative braking.
“Even for me, a result of 1,338 kilometres was a pleasant surprise,” says Marczyk. The record driver attributes this to the interplay of the drivetrain, battery, and low aerodynamic drag.
Aerodynamics Prove Their Worth on Long Distances
Technically, the A6 Sportback e-tron is based on the Premium Platform Electric (PPE). The tested Performance variant features a battery with 100 kWh gross and 94.9 kWh net capacity, as well as an 800-volt architecture.
For such a range attempt, aerodynamics likely play a significant role. The A6 Sportback e-tron achieves a drag coefficient (c W) of 0.21, making it Audi’s most aerodynamic production model to date, according to the manufacturer. At higher speeds, the proportion of air resistance in energy consumption increases significantly. Audi states that it accounts for around 40 percent of consumption in the WLTP cycle for the Sportback.
Regenerative braking also contributes. The vehicle can recover up to 220 kW during deceleration. According to Audi, this allows around 95 per cent of everyday braking manoeuvres to be handled without using the mechanical brake.
However, this record should not be confused with a new realistic range figure. Anyone who drives on the motorway at 130 km/h in the morning, cranks up the heating, and wants to have ten percent charge left at their destination will not squeeze 1,338 km out of 94.9 kWh. But that is not the point.
Such record drives are less about everyday testing and more about a technical stress test in the opposite direction. Instead of examining how much power an electric car can deliver, they explore how little energy it needs under favourable conditions. This is why the 7.09 kWh/100 km figure is more interesting than the sheer kilometre count: it demonstrates the potential of aerodynamics, rolling resistance, regenerative braking, and driving strategy when all factors work in the same direction.
This type of efficiency record is not entirely new for Marczyk. As early as March 2025, he covered 2,831 kilometres on a single tank of fuel in a standard Škoda Superb of the fourth generation with a 2.0 TDI engine. The average consumption at the time was 2.6 litres per 100 km. Now, he has transferred the same ambition to an electric car – this time, the focus was on extracting every last kilowatt-hour instead of maximising kilometres per litre of diesel.
