2013 Infiniti JX: 18 mpg city, 24 mpg highway (FWD); 18/23 mpg (AWD)
Seven-passenger crossover utilities are hardly a fuel-efficient segment, but Infiniti has done its best to give the JX good gas mileage under the constraints of hauling around a large vehicle that may be filled with up to seven people and all their possessions. Infiniti says the JX offers the best fuel economy in its class, though how you define that class may be slightly tricky once you look beyond the Acura MDX.
The 2013 Infiniti JX is rated by the EPA at a combined 21 mpg if you order the front-wheel drive model, which falls to 20 mpg when you opt for the $1,100 all-wheel-drive option. Those break down into 18 city, 24 highway for the front-drive JX, and 18 city, 23 highway for the all-wheel-drive model.
Over a 100-mile test drive in South Carolina that blended highway travel, suburban errands, and two-lane back country roads, we saw exactly 20 mpg on our top-of-the-line JX test car.
That's good for a seven-passenger crossover, with only the all-wheel Toyota Highlander Hybrid seven-seater beating it at 28 mpg for its city, highway, and combined ratings. Whether Infiniti buyers would cross-shop even the most expensive Highlander is a different question, but overall, we give Infiniti good marks for fuel economy in its current competitive set--though we suspect other vehicles will equal or surpass it soon.
Among seven-passenger vehicles, the 2013 Infiniti JX is slightly better than average in fuel economy.
