In 1972 Saab brought production of the 1.85&nbsp;L slant-four in-house to their [[Scania AB|Scania]] division at a facility in [[Södertälje]]. An uncorroborated letter to the editor of [[Motor Sport (magazine)|Motor Sport magazine]] references a Saab press release of July 1970 that indicates that this was planned from the outset.<ref name="msmjul76"/> Following the transfer Saab embarked on a redesign of the engine that resulted in the Saab B engine. Displacement increased to 2.0&nbsp;L, but the bore diameter was {{cvt|0.3|mm|in|3}} smaller than the enlarged Triumph version, resulting in a swept volume of {{cvt|1985|cc|cuin|1}}.

Saab's B engine shared much with the original Triumph design, including bore centres and bearings, but some previously problematic features, such as the water-pump and its seal, were redesigned.
