The Bedrock Chassis is heading outside China for its first overseas passenger vehicle project, with CATL’s skateboard chassis arm CAIT signing a strategic deal with Turkish carmaker Togg.
The agreement, signed on April 29, would see Contemporary Amperex Intelligent Technology (Shanghai) Limited, or CAIT, work with Togg on a new platform for three B-segment electric vehicles.
The first model is expected to enter mass production in 2027.
CAIT would bring its Bedrock Chassis technology and engineering know-how, while Togg would shape the user experience, product requirements and digital architecture.
Togg is not taking an off-the-shelf chassis and simply building a car around it. It is involved in the platform’s development from the start, so the final vehicles can better suit Turkish production needs and European buyers.
The Bedrock Chassis is CATL’s integrated intelligent chassis built around what it calls a battery-centric architecture. It combines the battery, electric drive system, thermal management system and chassis domain controller into one platform.
That allows the chassis to manage energy use and motion control, rather than acting only as a structural base.
CATL launched the skateboard-style chassis in late 2024 and has already rolled it out in China. The Togg project marks the next step: exporting the platform into an overseas passenger-car programme.
Togg also gets a shortcut into smaller EVs. The Turkish brand is already known for the T10X SUV, but this partnership moves it into the B-segment, where pricing, packaging and localisation would be more sensitive.
CATL describes the approach as a “1+1+1” localisation model: one chassis platform, one supply chain route and one local vehicle brand. The aim is to let domestic brands build EVs suited to their own markets while still using a common technology base.
CAIT is looking at more Bedrock Chassis partnerships in Europe and Southeast Asia. That could make this Togg project an early test case for CATL’s push into integrated EV platforms, not just batteries.
