Toyota's future EV architecture focuses on optimizing cabin space

Toyota is developing a new electric vehicle platform set to debut in 2028, featuring a redesigned layout to enhance interior space and comfort for passengers.

Toyota is developing a new electric vehicle architecture set to debut in 2028, replacing the current bZ family platform. A recent patent application filed in the U.S. offers a glimpse into the potential engineering solutions for this future base.

The core concept involves rethinking the layout of components under the floor. Instead of the classic "skateboard" architecture with batteries evenly distributed along the entire underbody, some electronics could be relocated to the area between the front seats. Notably, there won't be a traditional transmission tunnel.

This approach could address a major challenge for EVs: limited interior space due to battery modules. With smaller batteries, manufacturers sometimes have to raise the rear floor, compromising seating comfort. The new layout maintains the battery in the floor while optimizing the placement of auxiliary components. The benefits are clear: lower seating positions, an improved center of gravity, shorter power cable runs, and potential weight reduction.

Furthermore, it frees up additional legroom and headroom for second-row passengers. The new platform is expected to serve as a versatile foundation for various body styles, from SUVs to sports models. While space is less critical for crossovers, it could be a decisive factor for low-slung sedans and coupes.

If Toyota truly moves away from the classic "flat" architecture, it would mark a significant step in automotive development for the 2026–2028 period. The competition is no longer just about range but also about ergonomics. The question remains whether this patent will reach mass production or remain an engineering experiment.
