Leapmotor Introduces Advanced LEAP 5.0 Architecture and CTC 3.0 Battery for Future EVs

Leapmotor has announced the introduction of two pivotal technologies poised to redefine its electric vehicles (EVs), starting with models set to arrive in 2027. The Chinese automotive manufacturer debuted its LEAP 5.0 New Mobile Space Architecture alongside the latest version of its Cell-to-Chassis (CTC) 3.0 High-Low Fusion Battery during the 2026 Leapmotor Tech Day, held at the company’s battery facility in Hu Zhou, Hangzhou on September 16.

Reimagining Space Efficiency with LEAP 5.0 Architecture

The LEAP 5.0 architecture has been specifically crafted for Leapmotor's future EV models, emphasizing a dramatic increase in space utilization. According to the company, this new design framework offers 100% space efficiency compared to earlier models while integrating vehicle control systems into a centralized structure that supports both electric and increasingly automated functionalities.

A key innovation stems from merging the air-conditioning system with a rear-mounted powertrain. This integration reduces component count by 18% and decreases required piping by 30%, allowing for a significant 19% increase in cabin length. Furthermore, the redesign of the front suspension layout, featuring a vertical shock absorber with an aluminum tower, enhances front-row legroom by 37.5% while keeping cabin space unobstructed.

A New Interior Experience

With the architectural overhaul, Leapmotor is rethinking the conventional EV interior layout. The new skateboard-style platform contributes to an increased cabin height by 63.7%, resulting in an airy loft-like environment that allows for full standing height. This fresh approach not only maximizes space but also maintains the vehicle's exterior dimensions, potentially offering more flexible interior configurations without sacrificing road presence.

CTC 3.0 Battery Marks a Departure from Conventional Design

Leapmotor has also introduced the CTC 3.0 High-Low Fusion Battery, showcasing its advancements in battery technology that harken back to previous generations. This system incorporates battery components directly into the vehicle's chassis, facilitating a significant leap in integrating high- and low-voltage electrical functions.

With a seven-fold increase in low-voltage capacity compared to its predecessor, this new battery technology allows for the elimination of the traditional 12-volt lead-acid auxiliary battery— a component that has been a mainstay for various electrical systems in vehicles, from lighting to security features, for decades.

Shared Battery Systems Revolutionize Efficiency

Through the novel integration of battery cells and modules within the chassis, CTC 3.0 establishes a unified power distribution system that negates the need for separate modules. By sharing thermal management and energy distribution processes, this architecture allows the same battery cells to manage both high- and low-voltage needs, streamlining the overall electrical system and minimizing component count.

Leapmotor asserts that its future vehicles, which will be the first in over 70 years to forgo a traditional lead-acid auxiliary battery, will see enhanced performance due to this sophisticated design.

Considerations for Environmental Sustainability

The elimination of the conventional 12-volt battery could yield several long-term benefits. Lead-acid batteries frequently require replacement throughout a vehicle's lifespan, contributing to waste. Leapmotor’s CTC 3.0 system, engineered for lifetime maintenance-free operation, could liberate owners from the need for periodic battery replacements, while also significantly reducing the volume of lead-acid batteries entering landfills. The company estimates that widespread implementation of this technology could eventually eradicate the necessity for tens of millions of such batteries annually.

This shift in strategy reflects a broader trend among EV manufacturers as they seek to enhance the fundamental architecture of electric vehicles, going beyond typical metrics like range and charging speed.

Anticipating Leapmotor's Future

The LEAP 5.0 architecture and CTC 3.0 battery systems are designed to work in tandem, establishing a groundwork for Leapmotor’s future EVs. By concentrating on physical design elements rather than merely increasing battery capacity or adding software features, Leapmotor aims to reimagine vehicle packaging and structural efficiency.

With the first production models slated for unveiling in 2027, Leapmotor appears set to take significant strides in the next phase of its electric vehicle evolution.
