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.

GM design boss Welburn says Lincoln isn't a Cadillac rival [w/poll]

General Motors Vice President of Global Design, Ed Welburn, had some dismissive words for a certain cross-town luxury brand during an interview with Car and Driver. When asked about his thoughts on Lincoln, Welburn deflected, before saying, "I don't consider Lincoln to be a competitor for Cadillac."
"They're not a global luxury brand. I don't consider them a competitor. Are they a competitor for Buick? Quite possibly. But not for Cadillac," GM's head designer explained. Welburn, who's been at the helm of GM Design North America since 2003 and is the first to hold the position of VP of Global Design, has been instrumental in the styling renaissance at GM, so predictably, Car and Driver's interview with him focused on the design aspect of cars.
During the interview, Welburn explicitly denied plans for a reborn Cadillac XLR, even as a new Chevrolet Corvette is hitting the market and strides are being made with Cadillac's V-Series performance arm saying, "We have a lot of cars that we're working on for the Cadillac brand. The XLR is not one of them right now."

Cadillac CTS-V spotted with big exhaust, new grille?

If you thought Cadillac was content to leave its twin-turbocharged Vsport as the range-topping CTS, think again. Behold, our first good glimpse at the next-generation Cadillac CTS-V sedan, sporting more aggressive styling (somewhere under there), meaty quad-exhaust pipes, and what very well could be a new face for the V-badged Caddies.
Creating an all-new grille design seems like an awful lot of work just for a prototype, so it's very possible that the vertical-bar treatment you see here could make its way into production. Our spy photographers have pointed out that they've seen this same sort of grille treatment on prototypes for the smaller ATS-V sedan, and we've heard V-series models may soon have greater differentiation from the standard vehicles that sired them - that seems especially necessary if Cadillac insists on expanding this whole Vsport range.
Regardless of how its front end looks, the CTS-V ought to be a real monster. Industry sources say we can expect to see a supercharged version of General Motors' 6.2-liter V8 under the Caddy's hood, and considering the current car already makes 556 horsepower and 551 pound-feet of torque, we wouldn't be surprised to see a decent increase in both of those numbers. After all, one of the CTS-V's main competitors, the Mercedes-Benz E63 AMG, is currently putting out 550 hp and 590 lb-ft of torque. Could this mean a 600-hp Cadillac is on the horizon?
