Foothill Transit, which is converting its entire bus fleet to electric power, is initially buying two zero-emission Alexander Dennis Enviro500 models, which hold more than 80 passengers, for use on highway routes between downtown Los Angeles and the San Gabriel Valley.
E500終於有純電版，但唔係同BYD合作，仲要係拎嚟飛公路
不過對張 rendering 有啲保留，居然車廂及車身同柴油版冇乜分別??
如果試驗成功，唔知香港啲公司有冇興趣試吓
