Questions and answers

Which is the heaviest convertible or roadster in the 1CARS catalog?

The BMW M4 (M4 (G82/G83) · 2020–present), with 1,953 kg (4,306 lb). Second is the Mercedes-Benz SL-Class with 1,815 kg.

How is this ranking compiled?

Each model appears once, with the highest kerb weight quoted for any of its versions. Makers measure weight differently (with or without driver and fuel), so treat gaps of a few dozen kilograms with caution.

Why is a model missing from the list?

A model is listed only when the 1CARS catalog has a confirmed figure for it. Models without an official figure stay out instead of getting an estimate, and the list grows as we add data. Concept cars, prototypes, one-offs and racing cars are not ranked; limited-run models are marked.
