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.

Where the 12.8L 6-cyl sits in the Cascadia engine lineup

Every engine family this model was sold with, ordered by size. The bar spans the model years recorded for it; the price is a reference across priced configurations, with each configuration weighted equally. Older engines look cheaper because the cars are older — overlapping years alone do not match the vehicles by age, trim, mileage or condition.

The 12.8L 6-cyl Cascadia: common questions

Which Cascadia years have the 12.8L 6-cyl?

2010–2024, without a break — 15 model years in our VIN decode, across 98 factory configurations and 5,559 VINs.

What does a 12.8L 6-cyl Cascadia cost?

$26,995 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?

Detroit DD13 — 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.
