# Auto-Data.net > Free public catalogue of car technical specifications — 350+ brands, 3,500+ models, > 10,000+ generations and 55,000+ individual modifications, published in 14 languages > since 2010. Operated by Automotive Data Ltd, Stara Zagora, Bulgaria. Each entry covers engine and powertrain data, performance figures, fuel consumption, dimensions, weights, body type, drivetrain, brakes, suspension and tyre sizes, plus battery and range figures for electric and hybrid vehicles. Records are compiled from publicly available sources — manufacturers, retailers and industry experts — and updated daily. More than half of the catalogue covers European-market cars, with American and Asian coverage expanding. The catalogue is organised in four levels, and the URL pattern is predictable: - Brand: /en/{brand}-brand-{id} - Model: /en/{model}-model-{id} - Generation: /en/{generation}-generation-{id} - Modification: /en/{modification}-{id} Replace the /en/ segment with bg, ru, de, it, fr, es, gr, tr, ro, fi, se, no or pl for the other language versions.
