The GMT900 platform is by far the highest volume chassis General Motors has here in the States, as it underpins the Chevrolet Silverado, Tahoe, Avalanche and Suburban, the Cadillac Escalade/Escalade ESV, and the GMC Sierra, Yukon and Yukon XL. We never had any doubt that GM would continue to build body-on-frame trucks in the future, but with demand for SUVs shrinking quickly, some thought the body-on-frame SUV would soon be a thing of the past. Maybe not.
Our friends over at Pickuptrucks.com are reporting that the next generation of the GMT platform will be produced by Magna International's Cosma in Canada and Mexico – and that new platform will underpin the next-generation of GM SUVs along with the GMC Sierra and Chevy Silverado. Pickuptrucks quotes Magna spokesperson Scott Worden as confirming that the next generation of GM's large SUVs will come with the body-on-frame architecture. This sort of chassis tends to add weight versus a unibody platform, but it also adds capability for towing and payload at lower cost.
We're not really all the surprised that GM will continue to build BOF SUVs, especially when considering that the General sold a combined 200,000 copies of the Suburban, Yukon, Tahoe and Escalade last month alone. And last we checked, these are still relatively expensive vehicles that bring in quite a bit of desperately needed profit. And if customers are interested in a family hauler with better interior packaging and fuel economy, we're sure GM dealers will be happy to get them into a Buick Enclave, Chevy Traverse or GMC Acadia.
