WASHINGTON, Nov 2 (Reuters) – A group representing General Motors, ​Toyota, Volkswagen ‌and other major automakers on Monday backed the Trump administration ‌in ​a ⁠legal challenge to ⁠its sharply lower vehicle fuel economy standards filed by ​California and other states.

Last month, ⁠the US ⁠Transportation Department ​said it was finalizing ​a fleet wide fuel ‌economy average of 34.9 miles per gallon (14.7 ⁠km per liter) by 2031, down from 50.4 ⁠miles ‌per gallon (21.4 ⁠km per liter) ​that ‌had been approved ​under ⁠then President Joe Biden in 2024.
