CATL’s Bedrock Chassis will underpin three new B‑segment electric models for Türkiye after the battery giant’s CAIT (Contemporary Amperex Intelligent Technology (Shanghai) Limited) signed a strategic partnership with Turkish automaker Togg, the companies said Thursday. The deal marks the first time CATL’s integrated “skateboard” chassis will be supplied to an overseas passenger‑vehicle program, and the first overseas deployment of the Bedrock platform outside China.
Under the agreement, CAIT will provide the Bedrock Chassis technology and engineering support while Togg will lead vehicle product definition, digital architecture and user‑experience development for three models on its new B‑segment platform. The first model is slated to enter mass production in 2027, with the subsequent vehicles planned to follow into the Turkish and nearby European markets from mid‑2027 onward.
CATL describes the Bedrock Chassis as a battery‑centric, integrated intelligent underframe that consolidates battery cells, electric drive components, thermal management and a chassis domain controller into a single modular platform. The architecture — a modern iteration of the “skateboard” concept — is intended to enable faster, parallel development of multiple body styles on a common technical foundation and to reduce automakers’ R&D burden by outsourcing complex lower‑vehicle engineering.
Company statements highlight safety and modularity as key selling points. CATL has said the Bedrock design features a three‑dimensional bionic “turtle‑shell” underframe and can absorb up to 85% of severe crash energy, surpassing conventional chassis absorption rates. The platform successfully endured a 120 km/h frontal center‑pole crash test in internal demonstrations without thermal runaway, according to previously released CATL data.
CATL Chairman Robin Zeng framed the partnership as a milestone in the international expansion of the Bedrock Chassis following its mass‑production rollout in China in 2024, adding that the platform is built for global deployment through a “1+1+1” localisation approach combining a standard chassis technology, an industrial supply chain pathway, and localized operation with a domestic automaker.
Togg Chairman Fuat Tosyalı said the collaboration extends beyond a traditional supplier relationship, positioning Togg to help shape product requirements and the mobility ecosystem in Türkiye while saving development resources that can be redirected toward digital services and user experience.
The arrangement underscores CATL’s broader push to export integrated vehicle technologies beyond batteries, with the company pursuing partnerships across Europe and Southeast Asia to accelerate electrification in emerging markets. For Togg, the deal provides access to a ready‑made, scalable understructure intended to speed up time to market and support localized models tailored to regional preferences.
