GM global vehicle line executive for full-sized trucks, Rick Spina, has confirmed that the next Escalade, thought to be moving to the unibody Lambda chassis used by the Buick Enclave, Chevrolet Traverse, and GMC Acadia, will actually stay body-on-frame.
Given recent up-tick in sales of the GMT900 based SUVs (think Suburban, Yukon, Tahoe, and Escalade) GM has decided to invest in a new version of the platform and this will result in a new version of these body-on-frame, rear-drive SUVs being built to replace the current models.
The advantage of the body-on-frame design is normally higher load and tow ratings than a unibody design can match – making it the more desirable design for full-sized SUVs.
This will also cement the Escalade EXT’s future as well (a unibody version of the super-short-bed version of the Escalade would have been difficult to pull off).
