I Tested The New Porsche Cayenne EV's 400-kW Charging, And Even Without Reaching The Peak It's Fast As Hell
Jalopnik • • business
Key Points:
- The new Porsche Cayenne Electric offers a maximum DC fast-charging rate of 390 kW, allowing it to charge from 10% to 80% in about 16 minutes, placing it among the fastest-charging EVs currently available.
- The author tested the Cayenne EV at a 400-kW public charger in Toronto, achieving a peak charging rate close to 350 kW and confirming the manufacturer’s claimed charge time with a 13% to 80% charge in 16 minutes.
- The Cayenne Electric’s advanced double-sided battery cooling system helps maintain high charging speeds and battery health during fast charging sessions.
- Despite the high charging speed, 400-kW chargers remain rare in North America, limiting the practical accessibility of such rapid charging for most users.
- Even at premium DC fast-charging prices, the cost per mile for the electric Cayenne is approximately $0.18, which is notably cheaper than the $0.28 per mile cost for a comparable gas-powered Cayenne S, highlighting the cost-efficiency of electric driving.
