IS GENERAL MOTORS LAMBDA PLATFORM BIG ENOUGH FOR NEXT ESCALADE?

Rumours abound that with the soon-coming stiffening of miles-per-gallon standards in the United States that General Motors is considering arresting the development of larger Cadillacs (or has already) and that the next Cadillac Escalade won’t be on a shared platform with the GMC Yukon and Chevrolet Tahoe.

No, as the rumour goes, the gigantic Escalade could be a cooperative effort on the Lambda platform – the architecture that’s spawned the Buick Enclave, Saturn Outlook, GMC Acadia, and Chevrolet Traverse. 
Heresy, you say. Can you imagine such a backwards solution? What ‘Slade owner would be willing to sacrifice their magnitude and grandeur? 
Truth be told, of the three generations of Escalade produced so far, only the short-lived first-gen suffered in terms of differentiation. The first real Escalade (2001-2006) was a very unique vehicle, and the current Escalade is about as far from the Yukon and Tahoe as an SUV can get without jumping to a new platform. So fears that Cadillac wouldn’t be able to produce a sharp, edgy, high-class Escalade ought to be allayed with that realization.
Ignoring the Escalde ESV and EXT for a moment, have a look at the Numbers below. They show the dimensional differences between all-wheel drive derivatives of the regular Cadillac Escalade and the most luxurious Lambda to date, the Buick Enclave. Now, is it such a stretch…. or rather, such a shrink?
