What platform is Chevy Blazer?
The modern Chevrolet Blazer is built on General Motors' C1 platform, a unibody architecture shared with the GMC Acadia and Cadillac XT5.
In automotive terms, the platform refers to the underlying engineering and frame that support a vehicle’s structure, drivetrain, and features. The Blazer’s platform has evolved over time: the original Blazers used a truck-based, body-on-frame chassis, while the current model (introduced in 2019) adopts a unibody crossover design on GM's C1 platform, enabling a car-like ride with available all-wheel drive.
Current vs. historical platforms
Current generation (2019–present)
The 2019 Chevrolet Blazer uses GM's C1 platform (the family often described as a front-drive crossover architecture). It is shared with the GMC Acadia and Cadillac XT5, and supports two-row seating with optional all-wheel drive and turbocharged engine options, reflecting its role as a midsize crossover rather than a traditional truck-based SUV.
Earlier generations
Earlier Blazer models were built on truck-based, body-on-frame chassis that Chevrolet used for full-size and mid-size pickups and sport-utility trucks. Over time, Chevrolet shifted the Blazer name toward a unibody, crossover format, aligning it with GM’s modern midsize SUVs.
Bottom line: for today’s Blazer, the platform is GM’s C1 architecture shared with the GMC Acadia and Cadillac XT5; its predecessors used different, truck-based platforms, reflecting a shift from rugged body-on-frame designs to car-like unibody construction.
