Audi e-tron range, battery and charging

The Audi e-tron gets impressive rapid-charging capability, but we'd expect better real-world range given the large battery

Range Battery size Wallbox charge time Rapid charge time
186 miles 71kWh (e-tron 50) 10hrs 30mins (0-100%, 7.4kW) 1hr 4mins (10-80%, 50kW)
271 miles 95kWh (e-tron 55) 13hrs 45mins (0-100%, 7.4kW) 1hr 16mins (10-80%, 50kW)

The Audi e-tron 55's 271-mile official range is adequate, but a bit disappointing given the size of the battery. The Mercedes EQC has a smaller 80kWh battery but manages 259 miles of range, while the Jaguar I-Pace records 292 miles.

The e-tron can rapid-charge at 150kW, but a relative dearth of such stations in the UK right now means you'll be lucky to find one that can deliver that charging speed. It's normally only 50kW charging on offer at most motorway services in the UK, which will top up the battery to 80% in about an hour and 15 minutes.

Audi e-tron range

The 2019 Audi e-tron 55 returned a range of 248 miles in official WLTP tests, compared to a range of 292 miles for the Jaguar I-Pace. However, we've driven both of these cars extensively in the UK and found that the e-tron will manage a real-world range of some 192 miles, and the Jaguar is actually not much better, managing around 212 over varied roads in mild weather.

This is in part due to the fact – as with most electric cars – the e-tron keeps some of its battery capacity in reserve to help extend the battery's life. The e-tron has a usable battery capacity of 83.6kWh, which is very close to the usable capacity of the I-Pace.

We've not yet driven the upgraded 2020 e-tron 55, which has a larger 95kWh battery and claims a 271-mile range, nor the new-for-2020 e-tron 50, with a smaller battery and claimed range of 186 miles. As soon as we do, we'll update this review with real-world range estimates for both.

Charge time

The Audi e-tron has the potential to charge very quickly indeed, as it's capable of charging at speeds of to 150kW – faster than the EQC's maximum capacity of 110kW and the I-Pace's top charging speed of 100kW. That'll take the battery from 20-80% capacity in around 30 minutes. The problem is that 150kW chargers are currently few and far between in the UK, so you'll have to rely on 50kW units while out and about for the time being. That means a top-up time more like 90 minutes for the 2019 e-tron 55.

You can also charge the e-tron at home, of course; a standard 7kW wallbox will charge the e-tron in around 12 hours and cost around £11 at the average domestic tariff of 13p/kWh. Of course, charging can be scheduled for off-peak hours, when you could halve that cost by taking advantage of cheaper tariffs.

Battery warranty

Like Jaguar, Audi guarantees its electric vehicles' batteries for eight years or 100,000 miles; whichever comes first. That's on top of the standard manufacturer warranty of three years/60,000 miles, which covers the rest of the car. Unfortunately, there's no guarantee of battery performance, as there is with both Mercedes and Jaguar, both of which promise to replace the batteries if they drop below 70% of the as-new performance within eight years.
