Webasto Produces Batteries for Mercedes-AMG GT 4-Door Coupé

Webasto has commenced production of high-performance battery systems for the new Mercedes-AMG GT 4-Door Coupé at its facility in Schierling, Germany. The project encompasses both module and pack manufacturing, underscoring the site's role as a leading technology and competence center for advanced battery production.

Advanced Direct Cooling and Automation
The battery system is designed for peak performance, utilizing an innovative direct cooling method where a specialized oil flows directly around the individual cells. This ensures uniform heat dissipation, which is a critical requirement for sustained high power output. To meet the complex design and stringent quality demands of this cooling technology, Webasto employs highly automated production lines. These incorporate advanced laser welding techniques alongside AI-assisted inspection systems to guarantee process stability and ensure every battery meets strict performance parameters under demanding conditions.

Strategic Collaboration and Industrialization
Marco van der Weerd, Webasto’s global head of the battery business, noted that the successful industrialization of this complex product marks a significant milestone in the company’s expanding operations. Webasto CTO Marcel Bartling added that the close collaboration with Mercedes-AMG from the project's inception highlights Webasto's capability to deliver sophisticated, high-performance systems tailored to exacting customer specifications.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

Direct liquid cooling via dielectric fluid (often referred to as immersion cooling) is an emerging necessity in high-performance hybrids and electric vehicles. Unlike traditional cold-plate indirect cooling—which typically uses water-glycol mixtures and only cools the bottom or sides of a cell—direct oil cooling mitigates thermal build-up across the entire surface area. This allows for ultra-fast discharging and charging rates without prematurely degrading cell chemistry. The Schierling facility's deployment of AI-monitored manufacturing lines reflects a broader industry shift, where Tier 1 automotive suppliers are rapidly scaling specialized, high-margin electric powertrain infrastructure to meet the demands of luxury OEMs.
