BMW’s Neue Klasse EV family is unveiling its coupe version, offering a glimpse into the future of electric vehicles. Spotted by spies, the prototype reveals the presence of independent, hub-mounted motors. This design is a significant departure from the traditional motor-and-axle layout found in current EVs. The adoption of hub motors has been a long-suggested evolution for electric vehicles, despite facing challenges such as increased un-sprung mass at each suspension corner.
A closer look at the prototype wheel reveals an absence of brake calipers, suggesting that the outer face of the hub-mounted motor incorporates the hydraulic braking system. While this configuration addresses the weight issue associated with hub motors, it presents a new challenge—managing waste heat from the braking system. However, when it comes to innovation, BMW has a track record of pushing boundaries, as demonstrated by their introduction of “turbine” wheels.
Details about the platform for this coupe prototype are still limited, but BMW hinted at some specifications when they showcased the concept sedan in late 2023. The newly-developed battery cells on this platform promise 20% more energy density and 30% faster theoretical charging speeds compared to the current i4 model. Not only will these batteries be capable of storing more energy in the same-sized pack, but BMW also claims that overall vehicle driving efficiency will increase by up to 25% and even up to 40% in winter conditions, thanks to a new heat pump. These advancements are expected to result in a 30% increase in range compared to BMW’s current generation of EVs.
With the prototype displaying a body shape that indicates production-intent, BMW is likely approaching the stage where they will share more details about their next-gen powertrains. This development certainly piques our curiosity as to what BMW has in store for the future of electric mobility.
