Information sheet 30,New vehicle sales, Since 2001 annual new light vehicle sales have grown by 30 per cent surpassing. 1 million new light vehicle sales a year The vehicle mix has continued the trend. evident in 2001 namely a decrease in the proportion of passenger cars with an. increase in the all terrain wagon sports utility vehicle ATW SUV category Between. 2001 and 2008 passenger cars have decreased their share from 72 to 61 per cent. ATW SUVs have increased from 15 to 20 per cent and the light commercial vehicles. LCV share has grown from 13 to 18 per cent, Figure 1 illustrates the new light vehicle sales in Australia since July 1978. Figure 1 New light vehicle sales in Australia,New vehicle sales.

Average fuel consumption, The BITRE New Passenger Vehicle Database records fuel consumption as city highway. cycles as recorded in GRD The National Average Fuel Consumption NAFC was. calculated for the new vehicle fleet using the combined city highway fuel cycles. weighted by sales The fuel cycles were combined by using 55 per cent city and. 45 per cent highway fuel consumption values as per convention 1.

per cent lower than actual on road fuel consumption The Glass s dataset has continued to provide this information. Information sheet 30, New passenger cars have continued their downward trend in fuel consumption. with a steeper downward trend after 2004 Similarly ATW SUV fuel intensities are. declining possibly due to the emergence and popularity of the compact and. medium ATW SUVs The LCV category although somewhat volatile has remained. relatively flat and is the least fuel efficient part of the light vehicle fleet Figure 3. shows the relationship between the smoothed annual percentage decline in the fuel. intensity of total light vehicle sales and smoothed real petrol prices in Australia In. general when real petrol prices are high as in the early 1980s and in the period since. 2004 the decline in the average fuel intensity of new vehicle sales accelerates mainly. through buyers shifting to smaller vehicles, Figure 3 Declines in fuel intensity versus petrol price.

www greenvehicleguide gov au from 2002 onwards BITRE has estimated average. CO2 emissions from new light vehicles over time The estimates indicate an overall. drop in emissions intensity of new light vehicles of about 30 per cent over the period. see Figure 4 By 2008 the average CO2 emission level for light vehicles had fallen to. about 235 grams per kilometre, Figure 4 Average CO2 emissions per vehicle for new light vehicles. in Australia,Average CO2 emissions per vehicle grams km. Source BITRE estimates,Information sheet 30,Light vehicle power and weight trends. The new light vehicle fleet has continued a steady increase in power and a slight. increase in gross vehicle mass GVM The passenger car category however has. remained relatively flat for both power and GVM whereas the LCV and SUV ATW. categories have shown increases in mass and power However the top eight SUV. sales for 2008 all achieved more than 10 thousand sales and all were from either the. SUV Medium or SUV Compact categories the SUV category is disaggregated by. compact medium large and luxury, Figure 5 presents the trends in power and Figure 6 shows the trends in GVM.

Information sheet 30,Entire light vehicle fleet, The new passenger light vehicle fleet has carry on implications for the entire light. vehicle fleet Figure 8 presents the new light vehicle average fuel consumption together. with the entire light vehicle fleet rated average fuel consumption The new light vehicle. average fuel consumption has dropped a total 22 per cent since 1979 nearly 1 per cent. per year decrease whereas the entire light vehicle fleet has decreased a total 12 per. cent nearly 0 5 per cent per year The entire light vehicle fleet current value is similar. to the new light vehicle fleet value in 1987 indicating an approximate 20 year lag. But the rated value of the fleet intensity is based on the old 55 45 city highway split. which in reality is closer to 85 15 Also in the real world vehicle engines deteroriate with. time The combination of these two corrections means that the actual fuel intensity of. the light vehicle fleet is considerably higher than the rated value see Figure 8.

Federal Test Procedure USFTP standard which had city and highway components. which were weighted 55 45 The new United Nations Economic Commission for. Europe UNECE Type 1 test which underlies the Green Vehicle Guide GVG figures. has a freeway component but only 10 per cent of the test time is spent above. 70 kph This new standard also has much more acceleration deceleration in its city. component which apparently more than balances the limited freeway component. Figure 9 shows that the new combined standard is approximately equal to the old city. component which is probably the best approximation to the value the new standard. would have had pre 2003,Information sheet 30, Figure 9 Comparison of USFTP and UNECE standards for new light vehicles.

Conclusion, The trends evident in BITRE s earlier Information Sheet have continued since 2001. Vehicle sales have increased with the ATW SUV and LCV categories continuing to. increase their shares With the introduction of compact and more fuel efficient SUVs. the ATW SUV category has shown a considerable reduction in fuel consumption. LCV sales have been increasing along with power weight and a stable level of fuel. consumption, Australian consumers preference for vehicle characteristics that increase fuel. consumption power weight accessories 4WD capability has meant that potential. reductions in fuel consumption made possible by technological advances have not. been fully realised see Thoresen 2008 This is a worldwide trend in the automobile. sector and it cautions against undue reliance on technology alone to deliver. reductions in fuel use and emissions However that said the long term downward. trend in energy intensity has accelerated somewhat in recent years as the latest. generation of more fuel efficient light vehicles entered the market and buyers. downsized to smaller cars as petrol prices rose,Information sheet 30.
