Porsche Taycan 4 Cross Turismo (2025+, 800V)
97 kWh usable, peaks at 315 kW. Every figure below comes from the same engine as the calculator, run on this car's own charge curve. Charge curve estimated from published charging reports, last checked 2026-10-01. Not independently dyno-verified.
Fast charging, 10% to 80%
DC intake power against state of charge, 0 to 100%.
Highway range
The 80% to 10% window is the range most drivers plan a road trip around: you rarely arrive at a charger empty, and you rarely wait for 100%. Cold weather costs range twice, through denser air and the cabin heater; the 20°F figure has both.
Where these numbers come from
Tuned against Porsche's own published 10%->80% figure for the refreshed 105kWh-gross/97kWh-usable pack (~18 min, 320kW ceiling - simulated 20.0 min) - no named benchmark in the spec. Every 2025 Taycan but the base sedan has this pack. Highway baseline fitted to InsideEVs' 70 mph test of a 2025 Taycan 4 Cross Turismo on the New Jersey Turnpike: 302 mi, about 50F rising to 68F (fitted at 59F), on winter tires, so the fit reads low for a car on summer tires. The trim was changed from the 4S sedan, whose untested baseline put it at 194 mi, to the tested car.
The charge session is integrated across 1% state-of-charge steps on the curve above. In each step the rate is the lowest of the car's curve, the charger's power, the charger's current times this 800 V pack's voltage, and a cold limit that lifts as charging warms the pack. Highway range is road load: rolling resistance on 2,250 kg, drag on a 0.26 drag coefficient and 2.35 m² of frontal area, the always-on electrical load, a cold penalty and a cabin heater that works as hard as the weather asks (235 Wh/mi at 55 mph and 72°F). Formulas and their limits: how it works.
Pack age matters. These figures assume a new pack. The calculator takes a model year and odometer reading and derates both charging and range for an older one.
