Mazda patents reveal sports car with butterfly doors, RWD platform

Mazda has recently revealed patent filings for a new sports car that hints at exciting design and engineering innovations. Two patent documents have surfaced online, detailing a two-seater convertible sports car with a front-engine, rear-wheel-drive configuration. Most notably, the designs showcase the debut of butterfly doors, a feature never before seen in Mazda's production vehicles. While the specific model remains undisclosed, these patents have fueled speculation about Mazda's future sports car lineup.

The primary patent focuses on integrating butterfly doors into a front-engine, rear-wheel-drive convertible. Mazda appears to have achieved this by redesigning the A-pillar and suspension tower positions, incorporating reinforced structural support and front body bracing. This approach aims to maintain the structural rigidity essential for a convertible while ensuring the necessary strength for the unique door mechanism. This marks Mazda's first public disclosure of research into production-level technology for butterfly doors.

A second patent addresses collision safety, outlining a design that redistributes impact forces through the firewall, side sills, and rear structure to enhance occupant protection. Intriguingly, the patent diagrams clearly depict a longitudinal four-cylinder engine and a traditional driveshaft tunnel, differing from the rotary engine range-extender system featured in the Iconic SP concept car. This detail has led to varied interpretations regarding the intended application of these patents.

Given Mazda's commitment to lightweight, internal combustion engine principles for the next-generation MX-5 and its stated intention to bring the Iconic SP concept to production, these patents could signify technological directions for either model. However, the MX-5's established identity as a lightweight, affordable, and pure driving experience makes the inclusion of costly butterfly doors less probable. Therefore, many analyses suggest these advanced door designs are more likely destined for the higher-positioned Iconic SP. Alternatively, Mazda might be developing a shared new-generation front-engine, rear-wheel-drive platform that could underpin both the MX-5 and the Iconic SP, underscoring Mazda's continued dedication to driver-focused sports car development.
