SMB1568H is confirmed voith already by
more than 1 person who rode it..
So SGWiki states 1582 onwards voith is wrong.. maybe some buses
before 1582 alr has the voith gearbox just that no one discovered
it yet (1579 cfm ZF tho)...
SMB1566M, SMB1570A, SMB1573S, SMB1574P, SMB1575L, SMB1577G all ZF 6
gear...
