GM May Shrink Lambda Crossovers to Make Room for Unibody Tahoe Replacement (Visit this link)
The Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade – among others — are up for a redesign and in 2012, and GM engineers are seriously considering switching the SUVs to a unibody platform. Those SUVs currently ride on GM's body-on-frame GMT900 platform, which also underpins the company's full-size trucks. The switch to unibody construction would up the SUVs' fuel mileage, but would significantly reduce their towing and hauling capacities. GM already has a plethora of CUVs, thanks to its Lambda range, but we could see room for larger vehicles as the Tahoe and company will no longer be around in their current forms. GM could also downsize its Lambda CUVs over time to make more room for the full-size replacements. However, GM is considering continuing at least one body-on-frame SUV to satisfy the needs of those who need a heavy hauler.
