Audi Vehicle Models & Specifications

This hub indexes every Audi model line we hold verified data for — 46 nameplates covering 596 distinct trim and powertrain combinations across model years 2015 to 2027. That works out to roughly 13 variants per model line, which is why picking the exact year and engine matters when you compare fuel economy: two Audi vehicles wearing the same badge in the same year can differ by several MPG depending on drivetrain and transmission.

The deepest Audi coverage sits with the A5 (40 variants, 2015–2027), the A3 (36 variants, 2015–2026) and the A6 (36 variants, 2015–2026). 23 Audi models are still current as of 2027, while 23 lines have been discontinued or renamed — those stay published because used buyers and owners still look up their MPG, engine, and service data.

Every Audi model page below breaks its data into five focused views: fuel economy (EPA city, highway, and combined MPG plus estimated annual fuel cost), engine specifications (displacement, cylinder count, fuel type, and forced induction where applicable), transmission, drivetrain, and vehicle class. Where a Audi model is rated for towing or has published bed and cargo dimensions, those figures appear on the model page too. Figures come from the EPA and Department of Energy fueleconomy.gov datasets and are cross-checked against NHTSA vPIC records; blank fields mean the source data does not publish that value for that trim, not that the value is zero.

If you are cross-shopping, start with the model you already have in mind, note the combined MPG for the specific year and drivetrain, then use the comparison tool to put it side by side against a rival. Annual fuel cost is usually the number that separates two otherwise similar Audi trims over a five-year ownership window.
