Mazda appears to be preparing an electric successor to the ND-generation Miata (MX-5), which has been in production for over a decade. A recently revealed patent document from April includes technical details on EV powertrain layout, accompanied by schematics that strongly resemble the iconic Miata, drawing significant attention.
Filed in October 2024, the patent carries the generic title Electric Automobile, but the schematics clearly depict a classic two-seater sports car. What stands out most is the placement of the battery and electric motor. Unlike the typical skateboard-style EV platform that spreads a flat battery pack across the floor to lower the center of gravity, Mazda has concentrated battery cells in the transmission tunnel area.
This approach is intended to centralize weight and minimize the yaw moment of inertia—essentially reducing the heavy feeling when cornering. It aligns perfectly with the Miata’s longstanding emphasis on nimble, responsive handling.
The motor is also positioned within the tunnel. According to the drawings, it is located near the rear of the seats, creating a layout that pulls both front-rear and left-right weight distribution toward the center. Notably, Mazda has even registered a design that places a small battery in front of the passenger seat to offset the driver’s body weight—evidence of meticulous engineering aimed at achieving balance. Additional battery packs are shown placed directly behind the rear seats, further concentrating the vehicle’s mass toward the center.
Mazda has not officially commented on the release timing of the electric Miata, but it has repeatedly stated that it would not rush electrification until lightweight design goals could be met. This patent is seen as an exploration of the technical possibilities required to fulfill that condition.
Though mass production is likely still a ways off, the significance of this patent lies in showing that Mazda’s core philosophy—lightweight engineering and ideal weight distribution—may survive even in the EV era.
Since its debut in 1989, the Miata has become an icon of driving pleasure rooted in lightness and balance. However, the EV age has threatened that identity, as heavy battery packs often impair steering responsiveness and dynamic performance.
Mazda’s patent offers a blueprint for preserving what matters most to the Miata’s character—through an extremely precise design of battery placement, motor integration, and center of gravity. The proposed layout, featuring motor and battery integration behind the seats, in front of the passenger, and within the tunnel, draws from traditional internal combustion designs—something rarely seen in dedicated EV platforms.
While electric sports cars like the Porsche Boxster EV, MG Cyberster, and Alpine A290 are emerging, most focus on high performance or styling. Few pursue the essence of a lightweight, engaging driving experience. In that sense, Mazda’s approach stands alone.
