EV Platforms & Architectures

Electric vehicles are no longer defined primarily by trim levels or option packages. Instead, their behavior, longevity, charging performance, and software capability are governed by the underlying vehicle platform. This hub provides a structured, EV-native index of major global platforms in use today and those shaping the next generation of vehicles.

What Is a Vehicle Platform?

In an EV context, a vehicle platform is the foundational mechanical, electrical, and software architecture shared across multiple vehicles. It defines battery integration, voltage class, charging behavior, compute topology, and the scope of over-the-air updates.

Why Platforms Matter

Two EVs with similar size and price can behave very differently depending on platform design. Sustained fast-charging performance, thermal resilience, autonomy headroom, and software lifespan are all platform-driven attributes that traditional spec listings fail to capture.

Platform Lifecycle

Most automakers operate multiple platforms simultaneously. Legacy and transitional platforms coexist with clean-sheet, software-defined architectures as product lines evolve over time.
