Circuit/System Description
WARNING: This page is about a different car, the 2011 GMC Yukon, 2011 Chevrolet Tahoe, and 2011 Cadillac Escalade. However, it is still accessible from the selected car via links, so may be relevant.
This vehicle does not use a 12V starter motor to crank the internal combustion engine. A much more powerful 300V motor/generator located within the transmission is utilized to crank the engine. The 300V motor/generator can rotate the engine to operating speed, 800 RPM, within just a few hundred milliseconds. The 300V motor/generator allows near-instant starting of the engine. Once started, engine operation may cycle between Autostop, engine off, and Autostart, engine running, for the duration of the drive trip.
