Porsche Taycan vs Tesla Model Y: charging compared
Charging curves overlaid, time-to-charge at every common UK charger speed, and per-network cost — modelled on each car's actual charging behaviour.
At a 150kW UK rapid (10% → 80%): the Tesla Model Y finishes in 24m, around 3 minutes ahead of the PorscheTaycan at 27m.
AI-drafted intro · editorial review pending
The Porsche Taycan and Tesla Model Y are cross-shopped UK EVs in similar size and price brackets. The framing of this comparison: Pragmatic family EV vs flagship 800V.
Both cars' headline charging specs are available on their individual pages; the live tables below show how they actually perform across charger speeds and on every common UK network and home tariff. Where the chart's curve view shows one car holding a higher kW further up the SOC range, that car is generally the faster real-world charger at ultra-rapid sites; where the curves are similar, the practical difference at a 150kW UK rapid will be small.
Cost per mile at home is determined by the tariff and the car's real-world efficiency — both visible above. On a smart EV tariff (~7p/kWh off-peak), both cars cost a few pence per mile. On public rapid charging at PAYG rates, the gap between cheapest and most expensive networks is larger than the gap between most pairs of cars.
Use the tool above to model the specific scenario that matters for your driving — typical SOC range, your usual charger speed, your home tariff — and base the buying decision on those numbers rather than headline peak kW.
Charging behaviour
- Porsche Taycan
- Tesla Model Y
Time to charge by charger speed
SOC range 15% → 80%. Cells softer where the charger speed exceeds the car's peak DC — higher chargers deliver the same time.

Common questions
Which charges faster, the Porsche Taycan or the Tesla Model Y?
Use the time-to-charge table above; the answer depends on which charger speed you're comparing at. Headline peak DC isn't the whole story — the curve shape matters more for total session time.
Are these cars cross-shopped in the UK?
Yes — both are commonly considered in the same shortlist by UK buyers in this price and size bracket.
Which is cheaper to run?
On home off-peak charging, the more efficient car (lower Wh/mile) costs less per mile regardless of which is cheaper to buy. Compare the cost-per-mile table above.
