Method and data

Each model appears once, with the lowest 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. How we collect and check data

Ranked: 24 of 1,149 models in the 1CARS catalog have a figure for this list.

Not ranked: Porsche 356 №1 Roadster (585 kg) — prototype, not sold. Concept cars, prototypes, one-offs and racing cars stay out of the ranking; limited-run models are marked.

Questions and answers

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

The Caterham Seven (Seven I · 1973–present), with 440 kg (970 lb). Second is the Ariel Atom with 612 kg.

How is this ranking compiled?

Each model appears once, with the lowest 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.
