It’s important to note that there are currently no factory-made electric convertibles available in the U.S. The absence of electric convertibles is due to several challenges, including the packaging of EV components, weight, safety considerations, and cost.
Electric vehicles (EVs) are typically built on skateboard platforms that feature a flat battery pack under the floor and between the axles. This design allows for different body styles to be placed on top with minimal changes to the underlying platform. However, engineering satisfying roadster or convertible shapes with limited floor height for the battery pack can be challenging.
Moreover, convertibles have unique safety challenges as their body structures must handle collision forces without the added protection of a solid roof. While automakers have developed innovative safety technologies for convertibles, adapting these technologies to heavier EVs can be complex and costly.
Additionally, convertibles tend to have limited sales potential compared to other body styles, making them less attractive for automakers to develop. Consequently, there are currently no hybrid, plug-in hybrid, or fully electric convertibles widely available in the U.S. market.
Despite these challenges, some automakers are exploring the possibility of electric convertibles. For example, MG is developing the Cyberster, an electric roadster, but its availability in the U.S. remains uncertain. Luxury brands like Fisker, Genesis, and Rolls-Royce have also hinted at electric convertible models, but these are likely to be high-priced offerings.
In the future, we may see more electric convertibles as technology advances and automakers find creative solutions to the challenges posed by these open-top vehicles. Mazda, for instance, has hinted at electrifying its iconic MX-5 Miata roadster. However, fully electric convertibles for the mass market are still a rare sight in the U.S. for now.
