Sales-weighted fuel econ­omy slips in June

The Day - - AUTOMOTIVE DIRECTORY - By Day Mar­ket­ing

The av­er­age fuel econ­omy in newly sold ve­hi­cles in the United States fell back in June, ac­cord­ing to re­searchers at the Univer­sity of Michi­gan Trans­porta­tion Re­search In­sti­tute.

The typ­i­cal ve­hi­cle sold dur­ing the month had a com­bined fuel econ­omy of 25.1 miles per gal­lon. This was down from 25.3 miles per gal­lon in May and 25.2 miles per gal­lon in June 2016.

The de­cline marked the first drop in sales-weighted fuel econ­omy since Fe­bru­ary. The fig­ure had matched or im­proved upon the pre­vi­ous month's av­er­age in the three months prior to June.

UMTRI re­searchers Michael Si­vak and Bran­don Schoet­tle have been track­ing fuel econ­omy in new ve­hi­cle sales since Oc­to­ber 2007. In that month, the av­er­age ve­hi­cle sold in the U.S. got 20.1 miles per gal­lon. The fig­ure is cal­cu­lated us­ing monthly sales data as well as fuel econ­omy in­for­ma­tion on spe­cific ve­hi­cle mod­els from the En­vi­ron­men­tal Pro­tec­tion Agency.

The av­er­age sales-weighted fuel econ­omy reached a high of 25.5 miles per gal­lon in Au­gust 2014. Since then, it has wa­vered be­tween 24.8 miles per gal­lon and 25.3 miles per gal­lon. The model year av­er­age, or av­er­age fuel econ­omy for the months be­tween Oc­to­ber and Septem­ber, has held at 25.1 miles per gal­lon for three con­sec­u­tive years.

The re­searchers also cal­cu­late a fig­ure known as the Eco-Driv­ing In­dex, which mea­sures the es­ti­mated level of emis­sions gen­er­ated by a driver of a typ­i­cal newly pur­chased ve­hi­cle against those of a com­pa­ra­ble driver in Oc­to­ber 2007. This in­dex is up­dated on a two-month de­lay due to a cor­re­spond­ing lag in data up­dates from the Fed­eral High­way Ad­min­is­tra­tion.

The Eco-Driv­ing In­dex for April stood at 0.84, in­di­cat­ing that the typ­i­cal driver of a new ve­hi­cle was gen­er­at­ing emis­sions lev­els that were 16 per­cent lower than the base­line. This was un­changed from the pre­vi­ous year, but marked the first time since Au­gust that the in­dex has im­proved from the pre­vi­ous month. The low­est Eco-Driv­ing In­dex, 0.78, was recorded in Novem­ber 2013.

For the third month in a row, the dis­tance driven in the United States was 5 per­cent higher than in Oc­to­ber 2007. The fuel used per dis­tance driven in April was 20 per­cent lower than the base­line fig­ure.
