What if your EV could travel nearly 560 km farther than its claimed range? That’s exactly what an Audi A6 Sportback e-tron has just managed, covering a staggering 1338 km, or 831 miles, on a single charge. The run has also earned it a Guinness World Record for the longest distance travelled by a production electric car on a single charge.

The car in question was an Audi A6 Sportback e-tron Performance, which has an official WLTP range of up to 777 km (483 miles). Rally driver Miko Marczyk was behind the wheel for the record attempt.

The record attempt began in Poland at 1:55am on September 11, with Marczyk driving along the Vistula before passing through Krakow, Sandomierz, Warsaw, Torun and Grudziadz. He eventually reached the Baltic Sea at Hel, turned around and retraced much of the route. More than 45 hours after setting off, the Audi finally ran out of charge between Torun and Ciechocinek. And no, it wasn’t a case of putting the Audi on a trailer for half the journey. The entire attempt took place on public roads and included regular traffic, including rush-hour conditions. Temperatures averaged around 15 degrees Celsius and dropped as low as 7 degrees during the run. The record run took more than 45 hours, meaning Marczyk’s calculated average speed was under 30 kph. Audi hasn’t disclosed the exact figure, but the low average reflects the nature of the attempt, which was conducted in regular traffic and focused on extracting every possible kilometre from the battery.

The record car uses a single electric motor mounted on the rear axle, producing 365 bhp and 565 Nm. It also boasts a launch-mode output of 380 bhp. Despite being tuned primarily for efficiency, it can still accelerate from 0 to 100kph in 5.4 seconds and has a 210 kph top speed. The really impressive number, however, is the energy consumption. Marczyk averaged a staggering 7.09 kWh/100 km, which is less than half the Audi’s official combined consumption figure. He achieved that by driving with efficiency as the absolute priority, anticipating traffic, avoiding unnecessary acceleration and braking, making intelligent use of regenerative braking and keeping the tyres properly inflated.

The A6 itself also deserves plenty of credit. Its slippery Sportback body has a drag coefficient of just 0.21, making it Audi’s most aerodynamic production car. Underneath is a battery with 94.9 kWh of usable capacity, while the car’s regenerative braking system can recover up to 220 kW of energy. Put those things together and you have an EV that’s particularly well suited to an extreme efficiency run. Marczyk’s 1338 km distance represents roughly 72 per cent more than the A6’s official WLTP figure. And that really is something.

There is, however, a rather important catch. This isn’t the outright record for the greatest distance ever covered by an EV on a single charge. That belongs to the TUfast Eco Team’s tiny muc022 prototype, which travelled 2573.79km in 2023. Marczyk’s achievement is specifically a production-car record.

And while nobody should expect to buy an A6 e-tron, see 777 km on the range display and casually drive another 560 km on top of it, the run does highlight just how much driving style and aerodynamics can influence EV efficiency. Over 1330 km from a production EV is a rather remarkable number.
