- Power discrepancy
The P85D "Insane" was widely reported to have 691 horsepower,[1][2][3] but some owners reported 20% less power on dynamometer in various circumstances.[4][5]
Manufacturers are required by EU law to display power "at full setting of the power controller" (from an external DC source when performing laboratory vehicle approval), but not necessarily to show power limited by battery. Other equipment must be removed, or their power added to the measurement.[6][7] Actual power available depends on circumstances,[6] as it does for piston cars[8] which until 1972 could be 25-30% less than given.[9][10]
As of November 2015[update], Tesla website shows battery-limited 463 hp for P85D (532 hp for "Ludicrous").[11][4]
