Hyundai Will Build Its First Mid-Size Pickup on GM's Colorado Architecture
Hyundai is entering the mid-size pickup truck segment through an unlikely partnership. The Korean automaker will use General Motors' GMT 31XX platform, the same architecture underpinning the current Chevrolet Colorado, to develop a pickup destined for Central and South American markets. Production is scheduled to begin in 2028 at GM's São José dos Campos assembly plant in São Paulo state, Brazil.
The collaboration is part of a broader manufacturing agreement announced last year between the two companies, covering more than 800,000 vehicles annually across multiple segments. This pickup program represents the most visible product to emerge from that deal so far.
🔧 What Changes Under the Skin
Sharing a platform does not mean sharing identical trucks. Hyundai's engineering teams are making targeted modifications to the GMT 31XX architecture to suit both the brand's identity and regional market demands.
The rear axle is being reworked to increase load capacity, a critical spec for commercial buyers in Brazil, Argentina, and Colombia where pickups double as work vehicles. The powertrain strategy also diverges from the US-market Colorado. Engineers are adapting the platform to accommodate diesel engines, which remain the dominant choice for mid-size trucks across Latin America due to fuel cost advantages and established refueling infrastructure.
Body style options will include single-cab configurations, a format that has largely disappeared from the North American market but remains popular in South America for fleet and agricultural use. The Hyundai variant will carry its own exterior design, interior layout, and brand-specific technology features, distinguishing it clearly from the Chevrolet version rolling off the same production line.
GM Gets a Redesigned S10 Out of the Deal
Hyundai is not the only beneficiary. GM plans to use this same development cycle to launch a redesigned Chevrolet S10, the nameplate it sells across Latin America (distinct from the Colorado sold in the US and Australia). Both vehicles will share the updated GMT 31XX underpinnings and São José dos Campos manufacturing capacity, spreading tooling and production costs across higher volumes.
For GM, the math is straightforward. Platform sharing with Hyundai reduces per-unit costs on a vehicle line that serves a price-sensitive market. For Hyundai, it provides instant access to a segment where building a platform from scratch would require years of development and billions in investment with uncertain returns.
A Regional Play, Not a Global One
Neither the Hyundai pickup nor the revised S10 will reach North American dealerships. This is a product developed specifically for the economic and regulatory conditions of Latin American markets, where diesel powertrains, single-cab body styles, and payload capacity outweigh the tech-laden, crew-cab-dominant preferences of US and Canadian buyers.
Hyundai has been transparent about keeping its global pickup ambitions separate. The company has confirmed that a body-on-frame pickup truck is in development for the US market, built on a different platform and targeting a different buyer profile entirely. Executives have described that US-bound truck in enthusiastic terms, positioning it as a distinct product with no mechanical overlap with the GM-partnered Latin American model.
Why Brazil Is the Manufacturing Hub
GM's São José dos Campos facility gives both companies an established, high-capacity plant in the largest auto market in South America. Brazil sold over 2.6 million vehicles in 2025, and pickups represent a growing share of that total. Local manufacturing also sidesteps the steep import tariffs that make foreign-built trucks uncompetitive in the region. Mercosur trade agreements further benefit vehicles assembled in Brazil with preferential access to Argentine, Uruguayan, and Paraguayan markets.
The 2028 timeline gives both engineering teams roughly two years to finalize platform modifications, validate diesel powertrain calibrations, and establish supplier networks for region-specific components.
Two Trucks, One Factory, Separate Identities
The partnership between GM and Hyundai on this project is pragmatic rather than philosophical. Each company retains full control over its brand expression, dealer network, and pricing strategy. What they share is the expensive, invisible foundation: the steel architecture, the factory floor, and the economies of scale that make a mid-size pickup viable in a market where margins are tight. Production at São José dos Campos is targeted for the first half of 2028, with the Chevrolet S10 and Hyundai's yet-unnamed pickup expected to launch within months of each other across the region.
