The price reference is the median of configuration medians, not the median of all active cars. Each configuration has equal weight. Configurations with at least 3 priced listings are used when available; otherwise the reference uses the configurations with a recorded price. Model years, mileage and condition vary. Open a model-year report below for its asking prices across all engines.
Which XT6 years got a 3.6L 6-cyl engine
Every model year this engine was fitted to, newest first. The bar is how much of the family's VIN volume sits in that year — long bars are the years this engine was everywhere.
VIN counts come from our decode of the model's build patterns, not from live listings. A year link opens the full XT6 report for that year — every engine of the model, not just this one.

The 3.6L 6-cyl XT6: common questions
Which XT6 years have the 3.6L 6-cyl?
2020–2025, without a break — 6 model years in our VIN decode, across 36 factory configurations and 82,548 VINs.
What does a 3.6L 6-cyl XT6 cost?
$34,497 is a configuration price reference: the median of configuration medians, with each priced configuration weighted equally. It is not a listing-level median or a valuation of an individual car. The year-by-year ladder shows VIN and inventory counts; its links open model-year price reports covering all engines.
What is the engine code, and does it matter?
LGX — the code the VIN decodes to on the configurations on this page. It matters when you order parts or read a service history: the same displacement badge on another model can be a different code with different outputs.
