The US Senate has approved a bill that calls for all new cars and trucks to meet a corporate average fuel economy (CAFE) rating of 35mpg by 2020, up 40% from the CAFE levels of today’s fleets. The bill will now proceed to the House of Reps, which is expected to vote along the same lines.

The milder proposal put forward by Detroit Senator Carl Levin and the allied carmakers, which called for a standard of 36mpg for cars by 2022 and 30mpg for trucks by 2025, didn’t even make it to the voting round.

Under the new approved proposal, regulators would be able to void the 35mpg standard if there is “clear and convincing evidence” that it isn’t cost-effective, reports Automotive News. Other requirements include a call for the increase of ethanol production, fuel-price manipulation monitoring and more assistance for fuel-efficient vehicles, including hybrids, advanced diesel and battery technologies.
