Leapmotor Aims to Expand EV Cabin Space with New Platform

Leapmotor has unveiled two core technologies that will define its next generation of electric vehicles, starting with models scheduled for release in 2027. The company presented the LEAP 5.0 architecture and the CTC 3.0 battery system at a recent technology event in Hangzhou. These updates are intended to fundamentally alter how space and electrical power are managed inside the vehicle.

According to GN auto tech/ev, the manufacturer describes this shift as a significant leap forward, comparable to the industry’s move from basic feature phones to modern smartphones. The primary goal is to create a more efficient use of the vehicle's footprint while supporting increasingly automated driving features.

Interior space gains from structural changes

The LEAP 5.0 architecture focuses on reclaiming space that was previously occupied by mechanical components. By integrating the air-conditioning system with the rear powertrain, the design reduces the number of parts and cuts down on piping. This consolidation allows the cabin length to increase by 19% without making the exterior of the car larger.

The front suspension has also been redesigned to minimize hardware intruding into the passenger area. A new vertical shock absorber setup increases front-row legroom by nearly 38%. Additionally, a new flat-floor platform design raises the interior height significantly, creating a more open, loft-like environment where occupants can stand up fully.

Unified battery system removes auxiliary unit

The second major update involves the CTC 3.0 High-Low Fusion Battery. This system integrates battery cells directly into the vehicle chassis, eliminating the need for separate battery modules. A key feature is its ability to handle both high-voltage propulsion and low-voltage electrical functions using the same hardware.

This integration allows future models to remove the traditional 12-volt lead-acid battery, which has historically powered lighting, infotainment, and security systems. By sharing thermal management and energy distribution, the new system simplifies the vehicle's electrical architecture while increasing the capacity for low-voltage functions.

Trade-offs in component integration

While the space efficiency and electrical simplification offer clear benefits, these technologies rely on a high degree of component integration. The reduction in separate parts and piping means that maintenance or repairs may become more complex, as systems that were once modular are now deeply embedded in the chassis structure.

Drivers should note that these changes are not immediate. The first production vehicles utilizing the LEAP 5.0 and CTC 3.0 technologies are not expected to arrive until 2027. Until then, current models will continue to use the previous generation of architecture and battery systems.
