Audi e-tron GT vs Tesla Model S (2019-2020)

The Audi e-tron GT costs £7,205 more than the Tesla Model S. For that premium it adds 70 kW faster peak rapid charging and 84 kW more power. The Tesla Model S is not just cheaper - it also offers 340 litres more boot space and 1 more seat (5 versus 4). On EVcarsguide's combined category scores, the Audi e-tron GT comes out ahead overall.

The Tesla Model S is £7,205 cheaper to buy. Running costs are almost identical - about £184 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Tesla Model S comes out roughly £7,165 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 321 miles for the Audi e-tron GT and 280 miles for the Tesla Model S - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi e-tron GT goes roughly 41 miles further between charging stops. A rapid charge to 80% takes around 18 minutes in the Audi e-tron GT and 30 in the Tesla Model S, so the Audi e-tron GT loses less time at each stop. That makes the Audi e-tron GT the stronger long-distance car.

The two are within 0 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 436 mm of total clearance for the Tesla Model S.

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 Tesla Model S. 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.
