What are the four fundamental modular architectures of Geely Automobile?

[DiIvan]

Geely Automobile has introduced four global fundamental modular architectures (BMA, CMA, SPA, and SEA). Modular architecture divides a complete automobile structure into several modules, each assembled with components, and then integrates these modules together. BMA for A-segment vehicles: It is a compact modular architecture entirely independently developed and designed by Geely, meeting international technical standards. It retains the inherent high flexibility and scalability of the CMA–Compact Modular Architecture, initially co-developed by Geely Automobile Group and Volvo Cars. CMA for mid-size vehicles: This is the first mid-size vehicle fundamental modular architecture led by Volvo and co-developed with Geely, specifically designed for mid-size vehicles. It can cover products from A to B-segment vehicles. SPA for mid-to-large SUVs: SPA is Volvo's proprietary production platform. SEA for pure electric vehicles: The SEA architecture is currently the most extensive pure electric architecture globally, with a wheelbase range from 1800mm to 3300mm, covering all vehicle sizes from A to E-segment. It meets all styling requirements for sedans, SUVs, MPVs, compact city cars, sports cars, pickup trucks, and future mobility vehicles.

I've been researching Geely a lot lately and find their four major modular architectures really interesting. The BMA architecture focuses on compact practicality, specifically designed for small cars with exceptionally high space utilization. The CMA architecture was jointly developed with Volvo, compatible with both fuel and electric vehicles, offering a strong sense of quality. The SPA architecture is the premium flagship, used for larger models like the Lynk & Co 09, with platform rigidity that's beyond reproach. What impresses me most is the SEA浩瀚 architecture, a pure electric-exclusive platform featuring advanced 800V high-voltage fast-charging technology, with the Zeekr 001 as its representative model. Each of these architectures has its own expertise, and Geely's ability to expand its product line so broadly relies heavily on them as the foundation.

As someone frequently exposed to automobiles, I find Geely's four architecture design philosophies remarkably clear: BMA is like a flexible engineer, specifically addressing the space constraints of compact urban vehicles; CMA is the all-rounder, with hybrid compatibility making it akin to a Transformer; the SPA architecture leans towards stability, giving premium cars the sophistication of a well-tailored suit; SEA Haojiàn is the most radical, with its integrated battery-chassis design representing the future direction. Each architecture is developed and operated by independent teams, resulting in distinctly different product personalities.

From a technological evolution perspective, BMA is like modular building blocks that can quickly assemble compact cars; CMA possesses expansion genes, allowing the same chassis to spawn vehicles with different styles; SPA emphasizes material quality with an ultra-high proportion of aluminum alloy in the chassis; SEA represents a complete electrification revolution, integrating battery packs directly into the chassis to form a flat structure. This tiered strategy enables Geely to support vehicles ranging from 100,000 to 500,000 yuan with corresponding technical platforms.

After test driving the entire Geely lineup, I felt: BMA platform cars handle speed bumps very crisply, with more space than peers; CMA cars are exceptionally stable in corners, with surprisingly good quietness; SPA feels like a moving sofa, with no body sway even over potholes; SEA's most impressive feature is its charging speed - a coffee break can add 300km range. These four platforms are like the Four Great Inventions of the automotive world, doubling vehicle development efficiency.

Having followed the technological development of domestic cars for over a decade, Geely's architecture system is truly leading. BMA minimizes the manufacturing costs of compact cars, CMA triples the reliability of hybrid vehicles, SPA utilizes aerospace-grade bonding techniques to maximize body rigidity, and SEA's motor integration technology enables 0-100km/h acceleration to easily break into 3 seconds. Building cars now is like assembling LEGO—different architectures combine to create entirely distinct driving experiences.
