Audi e-tron GT (2021-2024) vs BMW iX

The Audi e-tron GT costs £1,495 more than the BMW iX. For that premium it adds 75 kW faster peak rapid charging. The BMW iX is not just cheaper - it also offers 123 miles more WLTP range, 95 litres more boot space and 1 more seat (5 versus 4). On EVcarsguide's combined category scores, the BMW iX comes out ahead overall.

The BMW iX is £1,495 cheaper to buy. The BMW iX is cheaper to charge, roughly £152 a year versus £208 for the Audi e-tron GT, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the BMW iX comes out roughly £1,775 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.

EVcarsguide estimates a real-world motorway range of about 253 miles for the Audi e-tron GT and 355 miles for the BMW iX - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BMW iX goes roughly 103 miles further between charging stops. A rapid charge to 80% takes around 18 minutes in the Audi e-tron GT and 35 in the BMW iX, so the Audi e-tron GT loses less time at each stop. So the BMW iX stops less often while the Audi e-tron GT stops for less time - pick on which you would rather do.

The two are within 6 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 436 mm of total clearance for the Audi e-tron GT and about 430 mm of total clearance for the BMW iX. The Audi e-tron GT also turns in a 1.2 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi e-tron GT and 84% for the BMW iX. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation. Both batteries carry a 8-year manufacturer warranty.
