Summary: Toyota Motor North America, Inc. supports the EPA's proposal to delay the Tier 4 standards and requests a further one-year extension to 2029 to allow for better evaluation of technology feasibility. The company argues that current standards are based on unrealistic BEV market projections and advocates for performance-based standards that preserve consumer choice and affordability.
