Which Lucerne years got a 3.9L 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 Lucerne report for that year — every engine of the model, not just this one.

Which Lucerne years have the 3.9L 6-cyl?
2009–2011, without a break — 3 model years in our VIN decode, across 21 factory configurations and 16,452 VINs.
What does a 3.9L 6-cyl Lucerne cost?
$6,990 is the typical asking price across the 189 cars with this engine on sale today. The year-by-year ladder above splits that by model year — the spread between the oldest and newest year is far wider than the spread between engines.
What is the engine code, and does it matter?
LGD — 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.
