GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

2019 GMC Sierra interior looks just like the Silverado's

The GMC Sierra has pretty much always been a Chevy Silverado in disguise. There was maybe some fancier trim plus the availability of the ritzier Denali trim, but the differences mostly amounted to different makeup on identical twins. As we can see from the spy photos above, the yet-to-be-shown 2019 GMC Sierra will actually have a more distinctive exterior, but the interior will continue the me-too tradition. Immediately apparent is the fact that the whole dashboard is carryover. It's the same chunky, plasticky place to be that, while likely highly functional, did little to impress when unveiled at the Detroit Auto Show. Really, only the volume, tuning and climate control knobs look different from those in the Silverado. They appear to have a different ridged pattern on the edges, and are possibly a shinier, glossier finish. The steering wheel also looks different, with a chunkier center and more svelte spokes. The Sierra exterior would seem to be better differentiated. The headlights are very different in that they wrap around the fenders more so than on the Chevy. The grille looks more vertical and aggressive than the Silverado's. The wheel arches also differ in that the forward corners are rounded and the rears are more squared off. The GMC Sierra will be revealed March 1 in Detroit. As per usual, it will probably share all of its powertrain bits with the Silverado. That means at least 5.3- and 6.2-liter gasoline V8s and the new turbocharged 3.0-liter inline-six diesel engine. Related Video: This content is hosted by a third party.

2015 Chevy Silverado, GMC Sierra heavy duty trucks unveiled

Proving just how important trucks are in the Lone Star State, General Motors has chosen the State Fair of Texas to reveal its new heavy-duty trucks from Chevrolet and GMC. Looking to take some of the wind out of the sails of the 2014 Ram HD and 2015 Ford F-Series Super Duty, the 2015 Chevy Silverado HD and 2015 GMC Sierra HD will have plenty to brag about when they go on sale in the first quarter of next year.
The bragging starts right up front with two available engines. The standard engine is a Vortec 6.0-liter V8 that produces 360 horsepower in the 2500HD and 322 hp in the 3500HD to go along with 380 pound-feet of torque in all applications. The true benefit of this powerplant is that buyers can opt for it to run on straight gasoline, E85 FlexFuel or even compressed natural gas (CNG). For maximum towing and even more flexibility, the 6.6-liter Duramax turbodiesel B20-capable V8 is the way to go, with its carryover 397 hp and 765 lb-ft of torque. Though the max towing abilities of 23,200 pounds (with a fifth-wheel trailer) are less than the 30,000-pound rating of the new Ram, the GM HD trucks offer better conventional trailer towing (19,600 pounds) and payload (7,374 pounds) than rival heavy-duty trucks...for now. The Duramax is paired with a six-speed Allison automatic transmission, while the gas engine gets GM's six-speed Hydra-Matic - no manual transmissions are offered.
Including the engines, GM continues to offer a broad range of configurations (more than 150, to be exact) including three cabs, two cargo bed lengths, numerous trim levels and, of course, the choice of single- or dual-rear wheels on the 3500. The HD trucks have faces that are similar to their half-ton counterparts, with the exception of a larger grille and bigger for improved air flow, and like the current HD offerings, the new Silverado HD and Sierra HD DRW models feature a one-piece bed design incorporating the fender extensions.
