Electrified powertrain control techniques include, in response to a detected cold start request for an engine, controlling one or more electric motors to generate drive torque to physically power an engine for a period to increase a temperature within a primary combustion chamber of a cylinder of the engine, and after the period, starting the engine by combusting a primary charge of fuel/air within the primary combustion chamber using a turbulent jet ignition (TJI) system to combust a pre-charge of fuel/air in a respective pre-chamber of the cylinder using a respective first spark plug and expelling heat energy therefrom into the primary combustion chamber of the cylinder, thereby eliminating a need for a respective second park plug of the TJI system that is associated with the cylinder and configured to heat and promote combustion within the primary combustion chamber.
