Audi Q6 e-tron - Range, charging & running costs
Strong residuals mark the Audi Q6 e-tron out, but it’s not the most efficient electric SUV around
Electric range, battery life and charge time
Of the four available powertrains, all but the base model get a battery with usable energy of 94.9kWh – the entry-level car gets a smaller 75.8kWh useable unit. For the ultimate range, the Performance model, with its big battery and single motor, is the one to have.
Official WLTP figures suggest that it’s capable of up to 393 miles between charges in Sport trim. That’s slightly up on the Quattro, which is claimed to manage 382 miles at best, or as little as 338 miles depending on wheel size. The SQ6 is said to cover 360 miles, while models with the 75.8kWh battery can do 326 miles.
Based on our time behind the wheel of the Edition 1 quattro, the car fell slightly short of the most pessimistic WLTP estimates. Our absolute best in conditions at around 15 degrees Celsius (most EVs tend to do their best work at closer to 25 degrees) produced an efficiency value of 3.1 miles per kilowatt hour, which translates to a range of 294 miles – 44 miles short of the lowest WLTP figure. That’s not bad for an SUV of its size, but things get worse in town, where the hefty Q6 achieves closer to 2.4 miles/kWh in stop-start traffic.

| Q6 e-tron 83kWh Sport | 83kWh (75.8kWh useable) | 326 miles | 44E |

Tax
The EV powertrain makes the Q6 e-tron incredibly cheap to run for company-car users, with Benefit-in-Kind deductions in the 2024/25 tax year starting from just £479 for a higher-rate tax payer choosing the entry-level car.
Insurance groups
Insurance groups range from 44 for the base Q6 e-tron Sport to 50 for the SQ6. Dual-motor models sit in group 49, so are likely to be higher, regardless of model.
Depreciation
By the usual low standards of large, electric SUVs, the Q6 e-tron’s resistance to depreciation is impressive, ranking above average for the new-car market as a whole. Our pick of the range, the base Q6 e-tron Sport, is predicted to cling on to 57.5 per cent of its value after three years, with even the most heavily depreciating SQ6 retaining over 50 per cent. Compare that with the base BMW iX, which is expected to hold on to only 45 per cent over the same period, and it’s clear that the Audi makes more financial sense.
