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 intends to offer semi-autonomous vehicles by 2020

Prepare for a few years of technological saber-rattling, as the world's automakers begin pushing to bring self-driving cars to market. Earlier this week, Nissan announced that it aims to offer autonomous vehicles by 2020, while Google, BMW and several other marks are working on similar efforts.
General Motors is doing things differently, though. Rather than push for a fully autonomous car, it's continuing to refine its semi-autonomous Super Cruise, a product that we tested in April 2012 and that will eventually see use on some Cadillacs before trickling down to the rest of the General Motors family. Super Cruise, which is undergoing testing in the Cadillac SRX, doesn't take complete control out of the driver's hands. Rather, under a very specific set of circumstances on the freeway, it will marry the capabilities of things like lane departure warning and adaptive cruise control to allow the driver to take their hands off the wheel. All of which sounds a lot like the system Mercedes-Benz is launching on the 2014 S-Class.
The system is still in development, according to John Capp, GM's director of electrical controls and active safety technology. Now that that the biggest hurdle, steering control, has been cleared, GM's engineers can focus on things like teaching the system to adapt to differing road conditions and visibility levels. As we reported in 2012, Super Cruise is still befuddled in low-visibility situations or when road markings aren't particularly clear.

Meet the other Cadillac wagon. It's as American as ABBA

The Cadillac CTS Wagon became a cult classic the second it went on sale. We all knew that it was never going to sell in anything approaching significant numbers, and if that "we" didn't include those actually working at GM, one would have to wonder what they were smoking. Cadillac was still having a hard enough time trying to convince people that it was now a BMW-fighting sport luxury brand rather than the purveyor of Grandpa-piloted land yachts. To many, a sport sedan like the CTS seemed like a stretch. But a CTS sport wagon? It sure seemed like GM was just doing things for funzies, an impression only enhanced by the CTS-V Wagon. Forget cult classic. That thing was an instant legend.  And yet, the CTS wasn't the only Cadillac of that era offered as a wagon. It wasn't even the first. Before GM said "to hell with it, let's have some fun" on this side of the pond, over in Europe, it had already taken a page from its old badge-engineering playbook to create the 2006 Cadillac BLS Wagon. It was available as a sedan, too, but its awkward majesty is best enjoyed as the long-roof model.  There's just something off about the whole thing, right? That's probably because it also looks vaguely familiar, as if you've seen it before. So where the hell does this thing come from? Sweden! Behind that Cadillac Art and Science face is a Saab 9-3, and in the case of the BLS Wagon, the Saab 9-3 Sport Combi wagon. The roofline is the dead giveaway, as no other wagon has ever looked like that. In fact, the roof and windows were the only exterior elements to copy directly over from 9-3 to BLS. No kidding. With the Cadillac front end, doesn't the Saab-funky-boxiness make it look like a miniature hearse? The answer is yes. GM's design team, led by Ed Welburn, was quite pleased with his work. Perhaps it even egged him on to create a real Cadillac sport wagon? "The whole team was very excited to apply Cadillac's design language to a wagon for the first time," said Welburn in a press release from the time. "The V-shaped chrome-plated grille, a Cadillac hallmark, is picked up again by the shape of the rear window, and the body side character lines make it unmistakably a Cadillac." The interior is surprisingly different from the 9-3, including the ignition switch migrating from the center console up to the steering column. It also wasn't exactly in keeping with the Cadillac norm of the time.
