SV6 and trim notes
Some Montana models were marketed as Montana SV6, a badge that signified a higher trim level rather than a different engine family. The SV6 typically used the same 3.4-liter V6 powerplant as the base Montana, with tuning and features that distinguished it in terms of equipment and styling rather than displacement or core output. If you’re shopping used, verify the exact specifications for the specific vehicle and year, as minor variations can occur by market or production run.
