CATL Strikes Bedrock Chassis Deal with Turkey's Togg for 2027 EVs

Key Takeaways

• CATL's Bedrock Chassis to power three Togg EV models from 2027
• Integrated battery‑in‑chassis design absorbs 85% crash energy, boosting safety
• First Chinese intelligent chassis supplied to overseas passenger‑vehicle market
• Togg saves R&D costs, can focus on digital user experience

Pulse Analysis

CATL’s Bedrock Chassis partnership with Turkey’s Togg signals a strategic shift in how battery manufacturers are positioning themselves as full‑vehicle technology providers. By embedding battery cells within a robust, three‑dimensional turtle‑shell underframe, the chassis not only delivers ultra‑high safety—absorbing up to 85% of crash energy—but also offers a modular platform that can underpin multiple vehicle variants. For Togg, leveraging this integrated solution shortens development cycles and reduces capital outlay on chassis engineering, allowing the automaker to concentrate on software‑driven features that differentiate its brand in a crowded EV market.

The technical merits of the Bedrock Chassis extend beyond safety. Its skateboard architecture decouples the vehicle’s upper body from the lower chassis, enabling parallel development streams and rapid model diversification. This modularity aligns with industry trends toward platform sharing, which can lower per‑unit costs and accelerate time‑to‑market. Moreover, the chassis’s ability to withstand a 120 km/h frontal pole test without fire risk addresses consumer concerns about battery safety, a critical factor as EV adoption scales globally.

From a market perspective, CATL’s move reinforces its dominance, now holding roughly 40.7% of the global EV‑battery share in early 2026. Expanding the Bedrock Chassis into Europe via Turkey positions CATL to capture a larger slice of the low‑carbon mobility transition, challenging rivals like BYD and South Korean manufacturers. The deal also illustrates a broader industry pattern where battery firms are becoming integral partners in vehicle architecture, reshaping supply chains and competitive dynamics across the automotive sector.
