According to MotorTrend, General Motors is considering fitting its 4.5-liter Duramax V8 Turbodiesel inside the Cadillac CTS sedan as a stepping-stone between the standard V6-equipped CTS and the barn-burning CTS-V.

Few icons are as synonymous with the American automobile as Cadillac and the station wagon, so it may come as a surprise that Cadillac has never officially offered a station wagon to American customers in its 106-year long history. Sure, there was the SRX crossover that came rather close, and the enormous Escalade SUV, as well. Cadillac even offers the BLS as a wagon, but that's only for overseas customers. Depending on which way you look at it, the new Cadillac CTS Sport Wagon may not be it either. Even with its edgy styling, the extended-roof CTS blurs the line between wagon and hatchback.

Put your checkbook away. As desirable as a CTS wagon in hot-rod V trim is, it's not here yet. The CTS Sport Wagon was developed as a way to offer the European market a configuration that's sure to sell, and it's headed to North America by the end of next year. When the Caddy wagon finally gets here, it will have the excellent 3.6-liter V6 providing power. Wagons aren't great sellers here, though, so the CTS Sport Wagon will likely be a niche model, dashing most of our hope that Cadillac will put its hottest powertrain in the two-box car just like BMW, Mercedes and Audi do.

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.

With enormous V8 land-yachts and even bigger Escalades rolling down America's boulevards, Cadillac doesn't have the most environmentally friendly of images. But that's a perception that the premium GM division is working hard to combat. After unveiling the Escalade two-mode hybrid, reports have begun to surface that Cadillac is considering a four-cylinder model for the American market like the Saab-based BLS it offers in Europe.

There are some old-timers out there who think Cadillacs should have big fins and V8 engines who aren't going to like this one bit. Emerging reports suggest that the General's luxury division may launch a four-cylinder model for the American market by 2011.

The Cadillac Cimarron from the '80s is perhaps the very best (or worst) example of rebranding gone awry. Based on the never-meant-for-a-Caddy J Platform, which underpinned the Pontiac Sunfire through 2005, the Cimarron marked the lowest point in Cadillac's illustrious history. The Caddy-that-wasn't is so bad, in fact, that it's claimed iconic status way earlier than most of Detroit's past iron, as evidenced by our reader-submitted Future Classics post from last year.
