Mazda's Innovative EV Design Could Revolutionize Sports Cars
A recent patent filing by Mazda has revealed an ingenious approach to designing electric sports cars, focusing on preserving the driving experience that enthusiasts adore. Unlike traditional electric vehicles that rely on flat battery packs under the floor, Mazda is exploring a vertical stacking method for batteries, placing them in the area traditionally occupied by a transmission tunnel. This design aims to maintain the lightweight and agile handling characteristics of its iconic MX-5 model. By concentrating the vehicle's mass closer to its center, Mazda hopes to reduce inertia and enhance agility, ensuring that future electric sports cars retain the fun-to-drive dynamics that have made the MX-5 a favorite among car enthusiasts.
In October of the previous year, Mazda submitted a patent to the US Patent and Trademark Office, which was later disclosed publicly in April. The diagrams within this patent depict a compact, two-door sports car reminiscent of the current MX-5 but equipped with an electric powertrain tailored to uphold the car’s renowned nimbleness. Instead of adopting the common skateboard-style platform used in most electric vehicles, Mazda proposes a novel layout where battery cells are stacked vertically in a column running through the space usually reserved for the transmission tunnel.
This innovative arrangement not only keeps the center of gravity near the car's midpoint but also aids in minimizing the yaw moment of inertia. As a result, the vehicle exhibits superior agility and more balanced handling capabilities. Furthermore, the design might incorporate extra battery modules situated behind the seats and a smaller pack positioned ahead of the passenger compartment. Such a configuration mirrors Rimac's Nevera, albeit tailored for less extreme performance objectives.
Another noteworthy aspect of this potential new electric sports car from Mazda is the placement of the motor. Rather than situating it between the rear wheels, Mazda suggests positioning it within the central tunnel. Through a differential, power is then transferred to the rear, concentrating most of the weight centrally. This strategic positioning ensures optimal weight distribution, further enhancing the car's performance and driving pleasure.
While the existence of this patent does not guarantee its transition into production, it signifies Mazda's commitment to preserving the essence of sports car handling as it ventures into electrification. Should the MX-5 evolve into an electric variant, it will undoubtedly continue to emphasize engaging driving dynamics, assuring fans that the spirit of the roadster remains intact even in an era dominated by electric SUVs and software subscriptions.
