Audi RS e-tron GT (2021-2024) vs Porsche Taycan (2020-2024)

The Audi RS e-tron GT costs £27,583 more than the Porsche Taycan. For that premium it adds 42 miles more WLTP range, 45 kW faster peak rapid charging and 85 kW more power. On EVcarsguide's combined category scores, the Porsche Taycan comes out ahead overall.

The Porsche Taycan is £27,583 cheaper to buy. Running costs are almost identical - about £216 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Porsche Taycan comes out roughly £27,583 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 246 miles for the Audi RS e-tron GT and 211 miles for the Porsche Taycan - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi RS e-tron GT goes roughly 35 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 18-18 minutes.

The two are within 2 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 RS e-tron GT and about 434 mm of total clearance for the Porsche Taycan.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi RS e-tron GT and 84% for the Porsche Taycan. 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.
