Tesla Model S or Porsche Taycan: the batteries compared
What the advert doesn’t say: capacity by version, the manufacturer’s warranty, and what a failure would cost.
The essentials
- Longest warranty: Tesla Model S, 8 years or 150,000 miles, against 8 years or 100,000 miles (Porsche Taycan).
- Cheapest to charge: Porsche Taycan, from £6.82 per 100 miles at home, against £7.41 (Tesla Model S).
- Module-by-module repair: feasible on Tesla Model S, not on Porsche Taycan.

Before you choose
A table compares models; you buy a car. Capacity depends on the version, the warranty on the date of first registration, and the state of health on the life the battery has had. The checker answers for one specific car: remaining warranty, expected state of health, cost of a failure.
