Tesla's flagship saloon targets the BMW 7 Series and Mercedes S-Class with 405 miles of WLTP range, a 0–60 time under 3 seconds on Plaid, and a price tag that looks reasonable next to its German rivals — until you check the options list.
Running costs: Tesla Model S
At 3.2 miles per kWh the Model S isn't the most efficient Tesla — its size and weight take a toll. Home charging at 26.1p/kWh costs around 8.2p per mile. Compare that with a BMW 5 Series 520i doing 38 MPG at 18.4p per mile (July 2026 prices) and the annual saving at 15,000 miles approaches £1,530. For executives covering significant mileage, the economics become compelling quickly.
