GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

2014 Cadillac CTS Vsport [w/video]

Bridging The Gap With Power And Poise
As you read these words, West Coast Editor Michael Harley is preparing to drive the brand-new 2014 Cadillac CTS along the gorgeous, sun-drenched roads of Southern California. And while I'll wait for Harley's full report before I put words in his mouth, I'm willing to bet he enjoys the hell out of Cadillac's new CTS. In fact, I'm sure of it.
I say this with confidence because, about a month ago, I spent the better part of a day flogging the new CTS Vsport around the 2.9-mile Milford Road Course - a challenging circuit laid out in the infield of an oval test track at GM's proving grounds in southeast Michigan. The MRC was built about a decade ago after Bob Lutz was lured out of retirement to work closely with GM's product development team, and thus, this circuit is known informally as the "Lutz Ring." The main objective of the MRC was to have an in-house facility for engineers to fine-tune vehicle dynamics, without having to constantly schlep cars over to Germany's infamous Nürburgring. (Of course, they still do.)

Cadillac Elmiraj Concept slinks in Leno's Garage

Jay Leno's Garage has moved to Pebble Beach for the week. This time around, the affable comedian is taking a look at the Cadillac Elmiraj Concept that debuted during the Monterey car week, and is talking to General Motors vice president of global design, Ed Welburn.
There's plenty of reminiscing about what concept cars were like when these two were kids, before a fairly deep dive into the striking Elmiraj Concept itself. Welburn shares a few anecdotes about the design process behind the two-door concept, including how his designers changed his mind on the grille design.
After bringing up the Cimarron, Leno makes a solid point that the Elmiraj would be a solid production car that could even spawn a four-door variant. We couldn't agree more. Take a look below for the full video from Jay Leno's Garage.
