NCAP Vehicle Variants and Ids by Make, Model and Year (NHTSA)

nhtsa/safety-rating-variants

The vehicle variants (body style and drive, for example 4 DR FWD) that NHTSA's New Car Assessment Program (NCAP) holds a safety-ratings record for, given a model year, make and model, with the VehicleId of each. Pass a VehicleId to the NCAP safety rating tool for the star ratings. An unknown make, model or year, or a model name that is not NCAP's own exact name (use the NCAP models tool to list them), returns an empty list rather than an error. Source: NHTSA, a US federal agency whose data is in the public domain. Not an official NHTSA product.
