Which S8 years got a 4.0L 8-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 S8 report for that year — every engine of the model, not just this one.

The 4.0L 8-cyl S8: common questions
Which S8 years have the 4.0L 8-cyl?
2013–2026 — 12 model years in our VIN decode, across 18 factory configurations and 3,941 VINs.
What does a 4.0L 8-cyl S8 cost?
$59,996 is the typical asking price across the 178 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.
Is the 4.0L 8-cyl turbocharged?
Yes — every configuration in this family decodes as turbocharged.
What is the engine code, and does it matter?
TFSI — 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.
