To get the most power out of an engine you disregard emissions standards, the manufacturer can't do that without getting fines and recall orders.

- tlb 1y agoEmissions are tested on a standardized driving cycle that doesn't include full-throttle acceleration, so emissions at full throttle aren't counted. Which is reasonable: high-performance cars spend only a tiny fraction of their time at full throttle so it doesn't contribute much to overall emissions.

See Supplemental Federal Test Procedure US06[0], required by the EPA for light-duty vehicle certification since 2007. It is also largely irrelevant in the real world: nobody is going to tune a car to have mediocre part-throttle performance but then go all-out on full-throttle. 0 - https://www.epa.gov/vehicle-and-fuel-emissions-testing/dynamometer-drive-schedules#US06 https://www.epa.gov/vehicle-and-fuel-emissions-testing/dynam...
