Mercedes-Benz EQE vs Porsche Taycan (2020-2024)

The Porsche Taycan costs £14,002 more than the Mercedes-Benz EQE. For that premium it adds 55 kW faster peak rapid charging, 155 kW more power and a 6.1s quicker 0-62mph time. The Mercedes-Benz EQE is not just cheaper - it also offers 170 miles more WLTP range and 1 more seat (5 versus 4). On EVcarsguide's combined category scores, the Mercedes-Benz EQE comes out ahead overall.

The Mercedes-Benz EQE is £14,002 cheaper to buy. The Mercedes-Benz EQE is cheaper to charge, roughly £176 a year versus £216 for the Porsche Taycan, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Mercedes-Benz EQE comes out roughly £14,202 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 281 miles for the Mercedes-Benz EQE and 211 miles for the Porsche Taycan - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz EQE goes roughly 70 miles further between charging stops. A rapid charge to 80% takes around 32 minutes in the Mercedes-Benz EQE and 18 in the Porsche Taycan, so the Porsche Taycan loses less time at each stop. So the Mercedes-Benz EQE stops less often while the Porsche Taycan stops for less time - pick on which you would rather do.

The two are within 5 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 439 mm of total clearance for the Mercedes-Benz EQE and about 434 mm of total clearance for the Porsche Taycan. The Porsche Taycan also turns in a 0.8 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 Mercedes-Benz EQE 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.
