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.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.

GM to squeeze out more production capacity for midsize trucks

General Motors was predicting a strong showing for the Chevrolet Colorado and GMC Canyon before they debuted, and demand among dealers for the midsize trucks even exceeded company's expectations. The positive situation has left GM with a problem, though: finding ways to increase capacity for the pickups at the Wentzville Assembly plant in Missiouri. With a third shift already running, GM has continued to look for ways to build just a few more of the trucks at the plant. The company has plans to hire as many as 1,000 more workers for the Saturday and Sunday shifts to construct an additional 2,000 pickups a month, according to unnamed insiders at the factory speaking to Automotive News. The little adjustments even extend to getting rid of an unpaid break to add 18 minute of assembly time over the course of a day, which equals about 3,500 more vehicles a year. All of this effort comes because the trucks are in such high demand. According to GM's figures, the company has delivered a combined 35,720 units of the Colorado and Canyon from January through April 2015, and the Chevy was the fastest-selling truck in the US for the previous three months. In May, it spent an average of just 12 days in showrooms before being snapped up. And even better for the company, 43 percent of these buyers came from other brands. According to Automotive News, the most popular trade-ins have included the Ford F-150, Toyota Tacoma, and Dodge Dakota. Related Video:
