Notes:
a Manufacturers must calculate their applicable full useful life SFTP standards
for non-methane hydrocarbon plus nitrogen oxides, particulate matter, and for
carbon monoxide (CO), if using the weighted CO standard. If not using the
weighted CO standard, manufacturers may use the full useful life stand-alone
Tier 1 standards for US06 and SC03.
b Gasoline and diesel vehicles only.
c 1.48 for diesel-fueled vehicles.
d 2.07 for diesel-fueled vehicles.
e Gasoline vehicles only.
f Standards apply at a useful life of 11 years or 120,000 miles.
g Does not apply to diesel-fueled vehicles.
