In recent years, the industry has been adopting modular platforms for electric vehicles, allowing components to be shared across different models. I wonder how this strategy impacts overall energy efficiency, both in terms of consumption and production. Do you think modularity truly delivers significant improvements, or could it introduce trade-offs that reduce performance? I’d love to hear your thoughts and experiences with this architecture.
How does the modular architecture of EVs influence their energy efficiency?

In my workshop, I've assembled several models based on modular platforms (for example, Geely's CMA architecture and VW's e-CMP) and I've noticed that modularity often reduces energy consumption in the production phase: by reusing frames, batteries, and transmission systems, materials and assembly time are saved, resulting in less electrical energy use and a smaller carbon footprint. In daily use, however, the impact depends on how additional modules are managed; if each variant carries “extra” components (such as larger battery packs or more complex climate control systems), the total weight increases and propulsion efficiency decreases slightly.
My practical advice: when choosing an EV based on a modular platform, review the list of optional modules and opt for the simplest configuration that meets your needs. Keeping the battery at its standard size and avoiding unnecessary add-ons like dual-motor systems usually offers the best balance between range and energy consumption. Also, check that the manufacturer has optimized the thermal management of the battery pack; good cooling prevents energy losses and extends the lifespan of the system.
