Provided are combustion engine starter systems and methods. A vehicle includes a combustion engine configured to crank start via torque applied to a crankshaft. The vehicle also includes a first electric machine to drive vehicle wheels powered by a high-voltage power source and coupled to the crankshaft and a second electric machine powered by a low-voltage power source and coupled to the crankshaft. The vehicle further includes a controller programmed to monitor a battery state of charge (SOC) and a voltage of the high-voltage power source. The controller is also programmed to activate only the second electric machine to attempt to crank start the engine in response to either of the SOC or the voltage being less than a predetermined threshold, and activate the first electric machine to attempt to crank start the engine in response to each of the SOC and the voltage being greater than a predetermined threshold.
