5.1 Distribution of LDV, LLDT and HLDT/MDPV

Table 8 summarizes the LDV, LLDT and HLDT/MDPV distribution of the Canadian fleet for the 2005 model year.

A total of 1 349 326 LDV/LLDT and 164 001 HLDT/MDPV were reported for the 2005 model year, for a combined total of 1 513 327 vehicles. The overall Canadian fleet for the 2005 model year was comprised of 58% LDV, 31% LLDT and 11% HLDT/MDPV. This distribution is comparable to the 2004 model year.

5.2 Distribution of Bins and Fleet Average NOx Values

Table 9 summarizes the distribution of vehicles by NOx standard (bin) and calculated average NOx values for each of the LDV/LLDT and HLDT/MDPV fleet.

The average NOx value for the fleet of LDV/LLDT was 0.1432473 grams/mile, which is 25% better than the applicable fleet average NOx standard of 0.19 grams/mile. In addition, approximately 78% of the LDV/LLDT fleet was certified to a bin having a NOx standard similar to or better than the applicable fleet average NOx standard for the 2005 model year (i.e. bin 8 or better).

For the fleet of HLDT/MDPV, the average NOx value was 0.334566 grams/mile, which is 22% better than the applicable fleet average NOx standard of 0.43 grams/mile. In addition, approximately 67% of the HLDT/MDPV fleet was certified to a bin having a NOx standard better than the applicable fleet average NOx standard for the 2005 model year (i.e. bin 9 or better).
