Caterpillar Inc. and Blue Bird Corp. today showcased Blue Bird's first school bus powered by Caterpillar's ACERT technology.
Caterpillar says it is the only engine manufacturer to offer both medium- and heavy-duty truck and bus engines that meet the U.S. Environmental Protection Agency's (EPA) 2004 emission standards, which require more stringent testing to demonstrate lower emissions over longer periods of engine operation.
Caterpillar signed a long-term engine supply agreement with Blue Bird to provide the majority of engines used in Blue Bird's school bus production.
