The EPA's most and least efficient automakers
The Top 5 and the Bottom 5
The EPA has released its findings regarding automakers' corporate average fuel economy, and the news is good overall. As an industry, average fuel economy increased by 0.5 mpg, despite an increase in truck and SUV sales, and almost all of the manufacturers that met the EPA's production number requirement (150,000 for manufacturers and 40,000 for makes) improved fuel economy. However, there are still companies that are more efficient than others.
The companies listed here represent the five most fuel efficient companies, followed by the five least. The fuel economy numbers are for the 2015 model year, the most recent year the EPA has finalized data for. The numbers were also obtained using the normal test cycle used to determine window sticker fuel economy, but with highway mileage weighted more heavily. Production numbers of different vehicles was another factor in the EPA's evaluation, which brought a couple of manufacturers down this year.
It's also worth noting that Volkswagen was excluded by the EPA because the company is still being investigated. For more details on the EPA's report, you can check out its summary here, or our story on some of the interesting tidbits here.
