AMCI Testing’s Certification protocol is based on the statistical imperative for unbiased, repeatable results:
- Testing was conducted over two specific routes: AMCI Testing’s Real-World City/Highway Route (commute-driving simulation in Normal Mode) and AMCI Testing’s Real-World City Route (city-driving simulation in Range Mode)
- Due to vehicle availability, testing was conducted in two waves: first Taycan Turbo and Taycan Turbo S; then Taycan 4S
- All driving was done during weekdays at the same time of day
- Each vehicle began every test cycle with its state-of-charge (SOC) indicator at 100%
- Each was operated on course until it entered its restricted-power “limp home” mode—which was considered the vehicle’s terminal mileage for battery depletion
- All accessory loads were held consistent during each testing cycle and headlights were set to “Auto”
Specific to the AMCI Testing City/Highway Route:
- The Taycan 4S, Taycan Turbo, and Taycan Turbo S were operated in Normal Mode with Regen set to “Auto” and HVAC to “ECO”
- Driving was precisely coordinated at the speed of traffic up to and including the legal speed limit during city driving, and up to 5 MPH over the legal limit on highways
Specific to the AMCI Testing City Route:
- The Taycan 4S, Taycan Turbo and Taycan Turbo S were operated in Range Mode with Regen set to “On” and HVAC to “Off”
- Driving was precisely coordinated at the speed of traffic up to and including the legal speed limit
