A belt driven starter motor system used to start an internal combustion engine. The system comprises a starter motor having a rotor and a pulley, a crankshaft pulley, and a belt tensioner, which are connected by a belt. The belt tensioner has a pulley that is movable between a first position and a second position. The tensioner pulley in the first position applies tension to the belt and the pulley in the second position corresponds to a condition wherein there is generally no tension on the belt. The starter motor begins rotation prior to the initial rotation of the crankshaft pulley, whereby the starter motor partially uses rotational energy to rotate the crankshaft pulley, which results in starting the internal combustion engine.
