Is the Honda Prologue built by GM?
The Honda Prologue is built by General Motors at GM's CAMI Assembly plant in Ingersoll, Ontario, using GM's Ultium battery platform, as part of a Honda-GM electric-vehicle collaboration.
What the Prologue is and why it matters
The Prologue marks Honda’s first all-electric SUV for North America and was developed in partnership with GM. It uses GM’s Ultium battery technology and electric-drive components, allowing Honda to leverage GM’s EV platform while bringing Honda’s design and engineering approach to the vehicle. The model represents a broader alliance between the two automakers to accelerate the transition to electric vehicles in the North American market.
Production location and who builds it
Key production details are explained below to clarify where the vehicle comes from and who is responsible for manufacturing:
- Location: CAMI Assembly plant in Ingersoll, Ontario, Canada
- Manufacturer: General Motors (GM) produces the Prologue for Honda
- Platform: GM’s Ultium battery platform underpins the Prologue’s powertrain
- Collaboration: Result of a Honda–GM EV development partnership established to share technology and manufacturing capabilities
These production details highlight the collaborative approach between Honda and GM, with GM handling the manufacturing at its Canadian plant and supplying the underlying EV technology.
Technology and platform: how the Prologue is built
The Prologue is engineered to ride on GM’s Ultium platform, a modular EV architecture that can accommodate different battery sizes and powertrains. By using Ultium, Honda gains access to scalable battery tech, electric motors, and associated electronics that GM has been refining across its own EV lineup. This arrangement enables shared parts, streamlined supply chains, and potential future joint products beyond the Prologue.
What this means for Honda and GM
For Honda, the Prologue provides a practical entry into the U.S. and Canadian EV market without building a wholly new manufacturing footprint from scratch. For GM, it expands production capacity for Ultium-based vehicles and strengthens the collaboration around future EVs. Together, the partners aim to accelerate electrification while leveraging each company’s strengths in design, engineering, and manufacturing.
Market rollout and current status
As of 2024–2025, the Prologue has been introduced in North America as part of the ongoing push to broaden Honda’s electrified lineup. It represents a milestone in the Honda–GM collaboration, with production anchored at a GM plant that has a long history of vehicle assembly in Canada.
Summary
The Honda Prologue is produced by General Motors at the CAMI Assembly plant in Ingersoll, Ontario, using GM’s Ultium technology, as part of a joint EV program with Honda. The arrangement reflects a strategic collaboration designed to speed up Honda’s electrification while expanding GM’s manufacturing footprint for Ultium-based vehicles. The Prologue stands as a concrete example of how automakers are sharing platforms and production capacity to bring electric vehicles to market more quickly.
