74 kWh usable, peaks at 248 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.
Calibrated against a 10%->80% / 72F / 350kW-stall E-GMP benchmark of ~18 min sustained 200+kW. Included as the 800V baseline every other profile on this page is being compared against.
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 300 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.
