Relatively low gasoline costs have moved shoppers away from alternative power types and traditionally efficient vehicle segments.

The WardsAuto Fuel Economy Index indicates the average fuel economy of light vehicles sold in the U.S. in July was 25.3 mpg (9.3 L/100 km), up just 0.5% from same-month 2014, the lowest year-over-year improvement since August 2010.
The national average gasoline price was $2.88, 0.2% less than in June and 21.9% below year-ago. July marked the 12th consecutive month of year-over-year price declines, eight of which are in the double-digits.
Consistently low gas prices have moved shoppers away from hybrid and plug-in hybrid models, likely bringing market share of these power-types to a 4-year low for full-2015. Also, the average fueling cost of a standard gasoline-powered light truck so far in 2015 is lower than that for cars in 2014, encouraging the growing share of the light-truck segments.
Diesel and electric variants of the Golf helped boost Volkswagen’s July rating up 7.0% from same-month 2014. At 30.3 mpg (7.8 L/100 km), VW was still the only automaker (except electric-only Tesla) above 30 mpg (7.8 L/100 km).
Jaguar Land Rover hit a record-high 19.9 mpg (11.8 L/100 km), nearly reaching the 20 mpg (11.8 L/100 km) benchmark already passed by every other automaker on the index. An unusually high share of CUVs over SUVs lifted July’s result 5.2% above year-ago. However, JLR was up only 0.8% year-to-date
Subaru posted a small uptick from last month to an all-time high 27.5 mpg (8.6 L/100 km), up 4.4% from last year due to a shift to cars from CUVs.
Nissan experienced a significant drop in the sales of EVs and small cars, bringing the automaker’s rating down 5.7% in July and 2.0% year-to-date.
Toyota has seen share of all car segments and alternative power types drop in favor of trucks and standard gasoline powertrains. A 2.4% downturn in July brought the 7-month average 2.3% below like-2014, the worst change of any index-tracked automaker.
Midsize cars are the only segment group with negative year-over-year results, down 2.6% for the month and 1.4% for January-July. This group has suffered the most from diminishing electrified-powertrain sales.
SUVs rose to a record 18.5 mpg (12.7 L/100 km) after a 6-month stretch at 18.4 mpg (12.8 L/100 km). These vehicles need the most improvement to reach CAFE standards and are the slowest growing light-truck segment on the index, up just 1.7% over the first seven months of this year.
Through July, the light-vehicle index rating sat at 25.4 mpg (9.3 L/100 km), up 1.1%, the lowest rise for the period in the 8-year history of the index.
