History
The B12 was Volvo's first large coach chassis with a vertically mounted engine, which limited the available body models that would fit. It was first fitted with the 12.0-litre TD122/TD123, which in 1995 was replaced by the 12.1-litre D12A. Because of the engine height it was probably less popular than the lower B10B, but it was Volvo's only rear-engined coach chassis that was offered as a tri-axle. The only other option for a tri-axle coach was the mid-engined B10M, and not all customers wanted to have the engine "where the luggage was supposed to be". It was succeeded in 2001 by the B12B, which had the same engine but in a horizontally mounted version. Like with the B6 (B6R) and the B6LE (B6RLE), the B12 was marketed as the ''Volvo B12R'' in Australia. They were of the standard version built in Sweden, and not related to the far more known B12R built in Brazil between 2003 and 2011. After Volvo had acquired Drögmöller in 1994, they changed production there from building complete chassis-less coaches to building on Volvo chassis, and the obvious choice was the B12. Out of all the different models Drögmöller had, only two went on to become Volvo models from 1995. The ''E320 EuroPullman'' became Volvo B12-500 and the ''E330H EuroComet'' became Volvo B12-600. They were only available in standard 12-metre length. Later the B12-600 became the basis for the 9900.Volvo B12B and B12R (Brazil)
The production of the B12 in Sweden ended in 2001 in favour of the B12B, but at Volvo's plant inEngines
