The US limits are not tested at the same cycle as the European, so it is a assumption, they can not actually be compared.
1 MY = Model Year
2 TLEV 10 % of manufactors production
3 LEV 25 % of manufactors production
4 ULEV 2 % of manufactors production
5 ZEV 10 % of manufactors production (Manufactors selling more than 3000 cars a year )
6 HC + NOx
7 Indirect injection / Direct injection
8 40 sec. runing before start of test is not permited
9 From year 2002 a cold start test by -7° C must be included
