EPA city/highway/combined MPG and CO2 for a model year + make + model.

Tool description as the model sees it

EPA fuel-economy ratings (city/highway/combined MPG, CO2 g/mile, fuel type) for a specific model year + make + model, from fueleconomy.gov (DOE/EPA), proxied live. Pass the model string exactly as fueleconomy.gov lists it (e.g. “Camry”, “F-150 2WD”, “Model 3”) — if unsure, call fuel_economy_models first to see valid model strings for that year+make. A model year/make/model can have several engine/transmission/drivetrain VARIANTS; this returns up to 5, each with its own MPG. Unknown make/model/year combos are refused with a clear error (never an empty success) and, when the make or model itself is not recognized for that year, list a few valid options.

Parameters

Name	Type	Required	Description
`year`	number	yes	Model year, e.g. 2024.
`make`	string	yes	Vehicle make, e.g. “Toyota”.
`model`	string	yes	Vehicle model exactly as fueleconomy.gov lists it, e.g. “Camry”. Call fuel_economy_models to see valid strings.
