Chinese electric vehicle (EV) battery manufacturer Contemporary Amperex Technology Company Limited (CATL) has announced it has entered into a strategic partnership with Turkish battery electric vehicle (BEV) manufacturer Türkiye Otomobili Girişim Grubu (Togg), to share its ‘Bedrock Chassis’ architecture for the development of a new range of compact passenger vehicles.

The agreement was signed by CATL’s chassis subsidiary, Contemporary Amperex Intelligence Technology (Shanghai) Limited (CAIT), and Togg, with the aim of developing a new range of B-segment passenger vehicles using CATL’s Bedrock Chassis. CATL confirmed that Togg will be the first overseas company to produce vehicles using its Bedrock Chassis.
CATL stated that under the agreement, CAIT will contribute its Bedrock Chassis technology and engineering expertise, while working closely with Togg to co-develop the platform for three new B-segment BEV models to be produced by Togg, which will be sold in Turkey and exported to markets in Europe and elsewhere. The first model is scheduled to go into mass production in 2027.
CAIT describes its Bedrock Chassis as an “integrated intelligent chassis built around a battery-centric architecture, combining core chassis components including the battery, electric drive system, thermal management system, and chassis domain controller into a single platform. This allows the chassis to manage both vehicle energy and motion control, effectively acting as a mobile energy carrier for the vehicle.
CATL’s chairman and CEO, Robin Zeng, said in a statement: “This collaboration represents another important milestone in the global expansion of the CATL Bedrock Chassis following its mass production rollout in the Chinese market. It will also serve as a benchmark project in the field of integrated intelligent chassis, strengthening our global partnerships, accelerating electrification and supporting the transition to low-carbon mobility in emerging new energy markets.”
Togg’s chairman, Fuat Tosyalı, stated: “We see mobility not merely as a product category, but as a holistic matter of technology and ecosystem. In this direction, we are taking the partnerships we establish beyond conventional supplier relationships and turning them into strategic partnerships that create shared value and build the future together. Rather than adopting a ready-made solution, we are becoming part of the entire development process, responding more effectively to user needs while also contributing to the development of this ecosystem in our country. In the period ahead, through such value-creating partnerships, we will further enrich the Togg ecosystem and the experience we offer our users by developing new solutions across different segments.”
CATL said that theBedrock Chassis has been developed for global deployment through a “1+1+1” localisation model. This model combines one chassis technology platform with one industrial supply chain pathway and the localised operation of one domestic automotive brand. The aim is to allow BEVs to be designed and produced in ways that reflect the needs of local markets while using a common technological foundation. “The partnership with Togg is expected to apply this approach in Turkey, supporting the development of vehicles tailored to regional consumer preferences while strengthening the local electric vehicle ecosystem.”
