The following sections summarize the lineup and where the 6.2 fit into it.

Note on availability
The 6.2L was not offered on every Sierra configuration. It appeared on higher-end models and with specific option packages, most notably the Denali trim. Confirming the exact engine for a given used vehicle requires checking the VIN or original window sticker.
Performance and features associated with the 6.2L
The 6.2L V8 delivered robust acceleration and strong towing capability, typically mated to a 6-speed automatic transmission. In the 2009 Sierra, some later refinements—such as cylinder deactivation features in higher-spec builds—could influence fuel economy, though the effect varied by model and equipment.
What buyers should know
If you’re evaluating a 2009 Sierra with a 6.2L, expect premium trim levels, higher fuel consumption relative to the smaller V8s, and strong towing specs. The Denali badge is a reliable indicator of the 6.2 option in that year.
