# Please find attached a series of tables and charts summarizing the results of statistical analyses

estimating the relationships between vehicle fuels consumption and size for inclusion in the

above-referenced docket. The Volpe National Transportation Systems Center conducted these

analyses in 2012 at the request of the National Highway Traffic Safety Administration to support

the evaluation of potential corporate average fuel economy (CAFE) and greenhouse gas (GHG)

emissions standards applicable to passenger cars and light trucks produced for sale in the U.S.

after model year 2016. Results show linear relationships fitted using a range of techniques for

adjusting fuel consumption values and weighting differences between observed (after any

adjustments) and estimated fuel consumption.

Please note that these analyses were conducted using market forecasts based on vehicles

produced for sale in the U.S. in the 2008 and 2010 model years, respectively. Fuel co-n-s-u

is reported in gallons per mile (gpm) and size is reported as vehicle "footprint" in square feet.Appendix:FinalRuleRegressionResultsTablesandGraphicsDepictingAnalysisusing2008and2010MarketForecasts8/2/20121U.S.DOTVolpeCenterRegressionResultsThefollowingtablesandgraphsdisplayresultsfollowingdisplayresultsforalloftheregressionsemployedintheanalysisTheseincluderesultsnotusedtoanalysis.includeresultsdevelopthecurves,whicharepresentedforcompleteness.8/2/20122U.S.DOTVolpeCenterRegressiondescriptorsNotation DescriptionolsormadOrdinaryleastsquaresormeanabsolutedeviationPCorLTPassengercarorlighttruckhp_wt_adjAdjustmentforhorsepowertoweightf djAdjfi hF i(SF )wt_t_austmentorwegttoootprntquareeetwt_ft_hp_wt_adjAdjustmentforbothhorsepowertoweightandweighttoFootprint(SquareFeet)initorfinalVehicleswithnotechnology(initial)orwithtechnologyadded(final)uorwUnweighted orweightedbysales8/2/20123U.S.DOTVolpeCenterMY2008‐BASEDMARKETFORECASTThefollowingtablesandchartsreflecttheMY2008BASEDMARKETFORECAST8/2/20124U.S.DOTVolpeCenterOLSRegressionResults2008FleetRegressiontype coefficient constantolsPC init w0 00117478‐0 01974olsPC__init_w0.001174780.01974olsPC__init_u 0.00108464‐0.00983olsPC_hp_wt_adj__init_w 0.00079953‐0.00299olsPC_hp_wt_adj__init_u 0.00089026‐0.00425olsPC_wt_ft_hp_wt_adj__init_w 0.00045244 0.012417olsPC_wt_ft_hp_wt_adj__init_u 0.00067315 0.003585olsPC_wt_ft_adj__init_w 0.00082769‐0.00434olsPC_wt_ft_adj__init_u 0.00086753‐0.002olsPC__final_w 0.0005101‐0.0045olsPC__final_u 0.00046357 0.001844olsPC_hp_wt_adj__final_w 0.00029287 0.005201olsPC_hp_wt_adj__final_u 0.00035105 0.005076olsPC_wt_ft_hp_wt_adj__final_w 0.00013112 0.01238olsPC_wt_ft_hp_wt_adj__final_u 0.00024987 0.008728olsPC_wt_ft_adj__final_w 0.00034835 0.002682l PC t ft dj fi l0 00036240 005496olsPC_wt_ft_adj__final_u0.00036240.005496olsLT__init_w 0.00048306 0.01825olsLT__init_u 0.00043169 0.024855olsLT_hp_wt_adj__init_w 0.00045272 0.019878olsLT_hp_wt_adj__init_u 0.00040929 0.025795olsLT_wt_ft_hp_wt_adj__init_w 0.00066245 0.008813olsLT_wt_ft_hp_wt_adj__init_u 0.00070791 0.009193olsLT wt ft adj init w0.000692790.007185olsLT_wt_ft_adj__init_w0.000692790.007185olsLT_wt_ft_adj__init_u 0.00073032 0.008253olsLT__final_w 0.00025133 0.010116olsLT__final_u 0.00022909 0.013763olsLT_hp_wt_adj__final_w 0.00023902 0.010777olsLT_hp_wt_adj__final_u 0.00022 0.014144olsLT_wt_ft_hp_wt_adj__final_w 0.00034715 0.005072olsLT_wt_ft_hp_wt_adj__final_u 0.00037397 0.005584olsLT_wt_ft_adj__final_w 0.00035946 0.004411olsLT_wt_ft_adj__final_u 0.00038305 0.0052038/2/20125U.S.DOTVolpeCenterMADRegressionResults2008FleetRegressionType coefficient constantmadPC init w0 00122022‐0 02131madPC_init_w0.001220220.02131madPC_init_u 0.00095855‐0.00572madPC_hp_wt_adj_init_w 0.00084028‐0.00449madPC_hp_wt_adj_init_u 0.00084216‐0.00256madPC_wt_ft_hp_wt_adj_init_w 0.00040396 0.014604madPC_wt_ft_hp_wt_adj_init_u 0.00061605 0.005864madPC_wt_ft_adj_init_w 0.00080206‐0.00319madPC_wt_ft_adj_init_u 0.00076199 0.001392madPC_final_w 0.00056031‐0.00699madPC_final_u 0.00033395 0.0065madPC_hp_wt_adj_final_w 0.00032298 0.003623madPC_hp_wt_adj_final_u 0.00028091 0.007726madPC_wt_ft_hp_wt_adj_final_w 0.00012532 0.012299madPC_wt_ft_hp_wt_adj_final_u 0.00020205 0.010432madPC_wt_ft_adj_final_w 0.00031689 0.003752dPC t ft dj fi l0 000257220 009175madPC_wt_ft_adj_final_u0.000257220.009175madLT_init_w 0.00045197 0.019843madLT_init_u 0.00034949 0.029135madLT_hp_wt_adj_init_w 0.00043667 0.021079madLT_hp_wt_adj_init_u 0.0003188 0.030296madLT_wt_ft_hp_wt_adj_init_w 0.00066743 0.008754madLT_wt_ft_hp_wt_adj_init_u 0.00065552 0.011852madLT wt ft adj init w0.000671830.00859madLT_wt_ft_adj_init_w0.000671830.00859madLT_wt_ft_adj_init_u 0.00067562 0.010725madLT_final_w 0.00024535 0.010603madLT_final_u 0.0002101 0.014381madLT_hp_wt_adj_final_w 0.00023411 0.011163madLT_hp_wt_adj_final_u 0.00019092 0.015373madLT_wt_ft_hp_wt_adj_final_w 0.00032725 0.006337madLT_wt_ft_hp_wt_adj_final_u 0.00035317 0.006403madLT_wt_ft_adj_final_w 0.00036207 0.004337madLT_wt_ft_adj_final_u 0.00036383 0.0059538/2/20126U.S.DOTVolpeCenter0.06GPMvs.Footprint(SquareFeet)‐Cars0.050.04
