Our Technologies
Technology is the core of our vehicle development. Since our establishment, we have made significant investments in our technological capabilities and research and development efforts. In 2022, 2023 and 2024, our research and development expenses amounted to RMB5,446.3 million, RMB8,369.2 million and RMB9,720.2 million (US$1,331.7 million), respectively, representing 17.1%, 16.2% and 12.8% of our total revenues for the same periods, respectively. Relying on these efforts, we have built a full-range technology stack including (i) E-Platform Structure, (ii) E/E Architecture, (iii) Zeekr OS, (iv) FOTA, and (v) Zeekr AD.

Sustainable Experience Architecture
Introduced in 2020, the Sustainable Experience Architecture (SEA) is an open-source, electric, and modular platform designed to innovate and optimize the design and engineering of Battery Electric Vehicles (BEVs). Development began within the Geely Group in 2016 and was officially announced in 2020. The Zeekr 001 is the first mass-produced vehicle based on SEA.
Key Technological Advantages

●   Superior Performance: SEA’s modular architecture delivers superior performance in range, NVH, charging, braking, and steering.
----------------------------------------------------------------------------------------------------------------------------------

●   FOTA Updates: Over-the-air updates ensure our vehicles stay equipped with the latest technology throughout their lifecycle.
-------------------------------------------------------------------------------------------------------------------------------

●   Efficient Development: Our deep understanding of SEA reduces the concept-to-completion process and development costs.
-------------------------------------------------------------------------------------------------------------------------

●   Versatile Application: SEA supports BEVs from A to E segments, including sedans, SUVs, MPVs, hatchbacks, roadsters, and robotaxis.
--------------------------------------------------------------------------------------------------------------------------------------

●   Customization Options: SEA offers extensive options for vehicle body, battery packs, motors, chassis, and braking systems, enabling longer wheelbases and shorter overhangs for enhanced passenger comfort.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

●   Open-Source: SEA is accessible to other BEV manufacturers, fostering collaborative innovation and technology sharing within the Geely Group.
