A vehicle engine electric starter motor can bring a vehicle engine crankshaft up to a desired spinning speed prior to igniting the accompanying vehicle engine by way of multiple speed ratios. The vehicle engine electric starter motor includes a planetary gearset assembly. The planetary gearset assembly receives rotational drive input from an armature shaft, and transmits rotational drive output to an engine flywheel. Amid use of the vehicle engine electric starter motor, the vehicle engine electric starter motor can provide a first speed ratio by way of the planetary gearset assembly between the rotational drive input and the rotational drive output in a first mode of operation. And the vehicle engine electric starter motor can provide a second speed ratio by way of the planetary gearset assembly between the rotational drive input and the rotational drive output in a second mode of operation.
