四千哩。环境保护署(EPA)的燃油经济性数据包括1980年前排放控制车型的乘用汽车、1975年至1980年的轻型卡车和1980年的摩托车(EPA首次列出摩托车)。这些数据包括按重量等级、车辆尺寸等级、制造商和英里数范围进行分层;国内与进口、汽油与柴油以及49个州与加州车型。1980年乘用车每加仑英里数比1979年增加了11%,这是由于惯性重量组合的变化,以及系统的优化。1980年柴油车平均每加仑28.6英里,比1980年汽油汽车每加仑22.2英里高出29%。即使有6000到8500磅。卡车增加到1980年的数据库中,销售加权的汽车/卡车车队mpg比1979年增加,平均重量和发动机排量下降。1980年轻型卡车车队平均每加仑17.1英里,而17.5英里,在1979年没有重型卡车。1980年摩托车车队的平均EPA城市mpg为54 mpg(不包括发动机小于50 cc的摩托车,越野车和销量较低的自行车)。
The 4000-mi. Environmental Protection Agency (EPA) fuel economy figures are presented for passenger cars from pre-emission control models through 1980, for light trucks from 1975 through 1980, and for motorcycles for 1980 (first EPA listing of motorcycles). The data include stratification by weight class, vehicle size class, manufacturer, and mpg range; domestic vs. import, gasoline vs. diesel, and 49-states vs. California models. Passenger car fleet mpg in 1980 is up 11% from 1979, due to a shift in the inertia weight mix, followed by system optimization. The 1980 diesel car fleet average (28.6 mpg) is 29% higher than that for 1980 gasoline cars (22.2 mpg). Even with 6000 to 8500 lb. trucks added to the 1980 data base, sales-weighted combined car/truck fleet mpg is up from 1979, and average weight and engine displacement are down. The 1980 light truck fleet mpg average is 17.1 mpg, compared to 17.5 mpg in 1979 without the heavier trucks. Average EPA city mpg for the 1980 motorcycle fleet is 54 mpg (excluding motorcycles with engines less than 50 cc., those for off-road use, and cycles with low sales volume).
