64 kWh usable, peaks at 143 kW. Every figure below comes from the same engine as the calculator, run on this car's own charge curve. Charge curve calibrated against a named, published dyno or road-test benchmark.
DC intake power against state of charge, 0 to 100%.
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.
Shares the 300e's pack and curve (same e-TNGA platform). Cold-gate calibrated against a 30F/150kW-stall benchmark of 50-60 min; highway range calibrated against a 75mph/45F/heat-on benchmark of ~115-125 full-charge, ~80-88 safe-window miles.
The charge session is integrated across 1% state-of-charge steps on the curve above, with the cold-weather intake limit applied below 68°F. Highway range applies aerodynamic drag scaling, a cold-air penalty and a temperature-dependent cabin heater to a 349 Wh/mi baseline. 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.
