WASHINGTON — The Detroit Three automakers again produced vehicles with the most emissions and the lowest fuel economy of any major manufacturers in model year 2021, according to new data from the U.S. Environmental Protection Agency.
Stellantis NV came in last in a field of 14 automakers for both measures, General Motors Co. was second-to-last and Ford Motor Co. was third-to-last. Both Stellantis and GM's fuel economy decreased and emissions increased between model years 2016 and 2021, according to EPA.
The three automakers also lagged behind their peers in model years 2019, 2018 and 2017. Stellantis has had the lowest fuel economy of any manufacturer every year since 2012. Tesla Inc., which produces only electric vehicles, has had the highest fuel economy every year since 2018.
