3car

3car is a hypothetical automotive platform and brand concept used in discussions of modular vehicle design. It is not associated with any established automaker or production model, and there is no verified production run or official company behind it. The concept is often cited in design and engineering debates about how a single chassis could support multiple vehicle classes.

The core idea of 3car is a modular skateboard-style chassis that can accommodate three different body configurations on a shared platform. The architecture would use scalable wheelbase and track measurements, swappable battery modules for electric propulsion, and adaptable drivetrains to allow gasoline, hybrid, or all-electric powertrains. The design emphasizes a small footprint for urban use while maintaining the ability to scale up to larger passenger and utility roles. By sharing essential components, proponents argue, manufacturers could reduce development time, cost, and material waste across multiple models.

Proposed variants commonly associated with the concept include a city car for dense urban environments, a midsize family sedan, and a light utility or crossover model. Each variant would use the same chassis and powertrain core but feature different exterior panels and interiors to suit its target market. Critics of the concept point to the challenges of achieving true cost savings, supply-chain complexity, and potential compromises in safety and performance across multiple configurations.

In sum, 3car represents a speculative approach to platform sharing and modular design rather than a current, real-world product line.
