Ten years of the Chevrolet Silverado 1500, graded

The Chevrolet Silverado 1500 is one of the nameplates on MotorGPA with every browseable model year scored — 10 scorecards from 2017 to 2026, each produced under the same framework and the same bands. That makes it the best single illustration on the site of what a decade of model years looks like when it is graded consistently, and of how a redesign and a refresh each show up in the data.

Year by year

What moved, and what moved it

Each scored year records, for every subject whose score changed by more than half a point since the previous scored year, the criteria that drove the change. The two largest per year:

Reading the decade

The table tells the story in three chapters, and they line up with the generation boundaries the production history records. The early years of the window are the previous generation in its last seasons — carry-over years whose scores move a point or two as reliability predictions and incentive availability shift. The generation change brings the subjects a new platform can change: Technology jumps as the infotainment is replaced, Performance moves on new towing and payload figures, and the first year of the new body is marked, as first years usually are, by a cautious reliability prediction that pulls that subject down before it recovers.

The refresh inside the current generation is where the largest single move sits, and it is Safety — the model year in which the driver-assistance suite became standard across the range rather than an option is the year the subject grade jumps, and because Safety carries a fifth of the overall GPA, the headline jumps with it. That pattern is not unique to this truck; Why pickups trail SUVs and sedans on Safety explains why it is the shape of every half-ton’s history, and Model years, generations and carry-over: how history is graded shows it across the fleet.

The subject that moved the other way over the decade is worth reading closely. Efficiency & Range fell across the window as the volume powertrain changed and the framework’s economy bands stayed fixed; that is a true statement about the truck as scored, and also a reminder that older years are graded against today’s bands rather than their own — Model years, generations and carry-over: how history is graded has that caveat in full.

Which year to buy used

The framework does not rank years for you, but the table does the arithmetic. The years after the refresh carry the current safety suite and the current infotainment at the previous body’s prices; the first year of the current generation carries the body without either, and grades accordingly. The evolution section on the 2026 Chevrolet Silverado 1500 page lets you put any two of these years side by side, criterion by criterion, which is the comparison a used-truck decision actually turns on.
