The articulated variant of the Bavarian B V was an unusual, 0-6-6, steam locomotive in the Royal Bavarian State Railways (Königlich Bayerische Staats-Eisenbahnen).

The articulated B V was a four-coupled locomotive built by Maffei at their own expense. It was based on the Class B V but, instead of having a third coupled axle, the back of the engine was supported by the front of the tender, called in German a Stütztender or "supporting tender". This was similar to the earlier Engerth design which articulated the tender with the main locomotive frame, allowing some of the weight of the fuel and water to be carried on the driving wheels to improve adhesion. Because the tender was articulated, rather than directly attached to the frame, the locomotive could traverse relatively sharp curves, while still enjoying the advantage of the additional adhesive weight gain. The articulated B V was not a success; it's riding qualities were poor and only one example was produced.
