- Togg will build three models based on CATL's Bedrock Chassis, with the first slated for mass production in 2027.
- The cross-border supply agreement marks the first time a Chinese integrated intelligent chassis will be supplied to the overseas passenger vehicle market.
CATL (HKG: 3750) has reached a partnership with an overseas automaker for its Bedrock Chassis, marking the entry of its integrated chassis technology into international markets.
The world's largest power battery maker announced on Thursday that it has reached an agreement with Turkish automotive brand Togg regarding the Bedrock Chassis.
CATL subsidiary Contemporary Amperex Intelligence Technology (Shanghai) Limited (CAIT-SH) and Togg will focus on the joint development of three models under the automaker's new B-segment platform, with the first model scheduled for mass production in 2027.
This is the Chinese auto industry's first joint development project to directly supply integrated intelligent chassis hardware to the overseas passenger vehicle market, according to CATL.
The cross-border supply agreement signals that CATL's Bedrock Chassis is expanding its global footprint. Under the new partnership, Togg, Turkey's best-selling domestic EV brand, will lead the definition of vehicle product requirements, CATL said.
CATL unveiled the Bedrock Chassis in December 2024, calling it the world's first ultra-safe skateboard chassis.
The skateboard chassis concept was originally introduced by General Motors in 2002. It allows for the decoupling and parallel development of the upper and lower vehicle bodies, thereby shortening the development cycle.
Centered around the battery system, the Bedrock Chassis employs an integrated technology that embeds battery cells directly into the vehicle's chassis to achieve a shared physical structure design.
The innovative chassis system can absorb up to 85% of severe crash energy, significantly higher than the roughly 60% absorbed by traditional chassis, according to information previously released by CATL.
Featuring a three-dimensional bionic turtle-shell underframe structure, the skateboard chassis can withstand a 120-kilometer-per-hour frontal center pole crash test without catching fire or exploding.
The technology, which allows automakers to build multiple different models on a single chassis architecture, will accelerate the shift toward modularity in automotive design.
Entrusting the highly complex chassis development to CATL is expected to help Togg significantly save on research and development resources, enabling the automaker to focus more on digital functional experiences.
Currently, CATL is continuing to expand its partnership footprint across various countries and regions, including Europe and Southeast Asia, to support the global transition to low-carbon mobility, the company said.
