The B12BLE features the 12-litre Volvo DH12 engine, which is based on the D12 engine from Volvo FH trucks. The DH12D engine meets Euro 3 emission level, and DH12E meets levels 4 and 5 with SCR technology. The engine is mounted horizontally, as it was in the B10BLE. The radiator is mounted at the rear on the right hand side.
From its launch in 2001 until 2005, it was available with the Euro 3 DH12D engine and ZF Ecomat2 & Voith D864.3E automatic transmissions. From 2004/2005, the B12BLE was available with an updated electrical system. Available transmissions were 6-speed ZF 6HP602C, Voith D864.3E and the Volvo I-Shift
Numerous public transport operators in Australia operate copious amounts of the B12BLE, either in its Euro III or Euro IV guises.
The Volvo B12BLEA was conceptualised for the State Transit Authority of Sydney, Australia because the B7LA was too underpowered for many of Sydney's bus routes due to the hilly terrain. The world's first B12BLEA entered service with State Transit Authority of Sydney in late 2005.
State Transit Authority has placed an order for 80 B12BLEA articulated buses, and they will be assembled with Custom Coaches bodywork. The custom buses are powered by the 12-litre Volvo DH12 diesel engine with 6-speed ZF 6HP602C automatic transmission.
State Transit Authority also ordered additional B12BLEA's in the Volgren CR228L body. The Volgren bodied buses are mostly seen running the high capacity Metrobus service. Most of the buses are built in Volgren's Tomago factory while the rest were built in Dandenong.
The Volvo B12BLE also come in a 12.5m configuration in Custom Coaches bodied CB60 and CB60 Evo 2 bodies. Volgren 12.5m variants were also ordered in both 12.5m and 14.5m bodies both Euro 5 complaint.
The 12.5m Custom Coaches CB60 are Euro 3 complaint while the newer CB60 Evo 2 bodied buses are Euro 5 complaint.
2 Volvo B12BLEAs are operated by Sentosa under the guise of a beach tram running on the island's Siloso Beach Tram route. The rear module of the bus consists of a large, sheltered standing area with an al-fresco seating area on the elevated part of the bus where the drive axle is. The buses are bodied by ComfortDelGro Engineering Corporation and are speed-limited for safety reasons. The vehicles were in Purple Livery.
