The definition of a roadster has historically been clear: a two-seat, open-top car focused on driving pleasure. However, as the automotive industry evolves with electric vehicles and new body styles, pinning down which cars qualify as true roadsters has become increasingly difficult.
According to automotive historians, classic roadsters like the Mazda MX-5 Miata and the original Lotus Elan set the standard with lightweight construction and manual transmissions. Modern interpretations, such as the Tesla Roadster (first generation, 2008-2012) and the upcoming second-generation model, challenge this tradition by adding electric powertrains and advanced technology, yet retaining the two-seat convertible layout.
Industry experts note that the rise of coupe-cabriolets and targa tops further blurs the line. Vehicles like the Porsche 718 Boxster are often called roadsters, but some purists argue that only cars with a fully removable soft top qualify. Meanwhile, the BMW Z4 and Mercedes-AMG SL also compete in this space, each with different interpretations of the roadster concept.
As of June 2026, no single regulatory body defines a roadster for legal or classification purposes. The term remains largely marketing-driven, with manufacturers using it to evoke sportiness and heritage. This ambiguity means that what one enthusiast calls a roadster, another might dismiss as a mere convertible.
