MotorTrend reports that GM insiders are saying that the next-generation Cadillac Escalade will jump from its current GMT900 truck platform to the Lambda crossover architecture that underpins the GMC Acadia, Saturn Outlook, Buick Enclave, and Chevy Traverse. MT points to the Buick Enclave Super that didn't happen as evidence that an Escalambda would be able to handle an eight-cylinder engine, which would be a step up from the rest of El Generalissimo's increasingly-crowded crossover lineup. Edgier, CTS-like styling would likely be a given, too.

Frankly, this is a good idea. The packaging afforded by the Lambda platform is vastly superior to what the GMT900 trucks offer. Remember that in the latter, the 3rd row is bolted to the cargo floor, it doesn't fold flat, and it's generally uncomfortable. The Lambda solves that instantly, and is better suited for what's positioned as a luxury vehicle anyway. Ride quality would be much better, and if GM Design were to deliver an interior on par with what's now found in the CTS, a Lambda-based Escalade would probably represent a quantum leap forward in terms of styling and refinement over the current vehicle.

As for the Avalanche-based Escalade EXT, MT says that GM's mulling over the idea of moving to a unibody pickup, a la the Zeta-based GMC Denali XT concept, to replace both of those vehicles. Again, not a bad idea, especially for Cadillac. The downside is that owners of the current vehicles who use them to tow will likely need to look elsewhere to fill that need. Still, if Cadillac's gig is to sell legit luxury vehicles, moving to more car-like platforms makes all kinds of sense. It's going to be really interesting to see if any of this stuff actually pans out.

The ruthless pruning continues, with GM Inside News reporting that the rear-wheel-drive Kappa II platform has gone to heaven before ever touching this mortal coil. Back in 2004, a vehicle line executive said "The Kappa architecture is a great platform for sporty, driver-oriented applications around the globe." Apparently, not one for which GM could make enough different models to actually earn some money.

Reasons for the sequel platform's demise are allegedly that the first hydra-formed Kappa is just too expensive to fabricate; the cars based on it use expensive, hydra-formed parts; assembly requires inordinate amounts of human labor; and GM didn't make its money back fast enough to justify the investment in a new RWD – read: thirstier – platform.

The current Kappa's suspension and design geometry aren't shared with any other car;, the platform was created to accept one engine, the Ecotec 4-cylinder; and it served under only four varieties of the same car: the Pontiac Solstice, Saturn Sky, Daewoo G2X and Opel GT. It was a lot to ask such a limited platform to achieve the volume's GM needed with cars on expensive underpinnings that didn't demand expensive prices. And if the rumors are true, then your Solstice GXP could be worth more than you expected, and sooner than you expected.
