For comparison's sake, most modern trucks manage between 5.5 and 6.5 mpg. For most long-haul truck drivers, an increase in fuel economy of 54 percent would equate to a savings of around $25,000 per year at current diesel prices.
The truck standard has to rise from 23.5 mpg to 28.8. This means cars must improve by 37 percent, trucks by 23 percent. Combined, cars and trucks in 2016 should average 34.1 mpg, up 35 percent from the current 25.3 mpgâa jump of 5.1 percent per year.While pondering these figures, keep in mind that the tests used to measure CAFE numbers are based on old city and highway tests.owever, the governmentâs 2016 fuel-economy numbers of 37.8 mpg and 28.8 mpg are projections because, unlike today, when every car and truck fleet must meet the same mandated average, the future requirements will be instead based on the size of each vehicle in a manufacturerâs fleet.
