| Analysis of WLTP Utility Factor Distributions |
| Reference Number: WLTP-06-08 |
|
Discussion of utility factors used in weighting emissions and fuel consumption. Utility factors are ratios based upon driver statistics and vehicle ranges recorded by off-vehicle charging (OVC) hybrid electric vehicles (HEV) (i.e., plug-in hybrid electric vehicles) in charge-depleting and charge-sustaining modes. |
