Audi RS e-tron GT vs Porsche Taycan Sport Turismo

The Audi RS e-tron GT costs £38,225 more than the Porsche Taycan Sport Turismo. For that premium it adds 50 kW faster peak rapid charging, 310 kW more power and a 1.9s quicker 0-62mph time. On EVcarsguide's combined category scores, the Porsche Taycan Sport Turismo comes out ahead overall.

The Porsche Taycan Sport Turismo is £38,225 cheaper to buy. Running costs are almost identical - about £176 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Porsche Taycan Sport Turismo comes out roughly £38,305 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 306 miles for the Audi RS e-tron GT and 293 miles for the Porsche Taycan Sport Turismo - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. 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 Sport Turismo.

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 Sport Turismo. 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.
