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.

GM phasing out light-duty 1500-series vans

In the market for a fullsize van but don't need a heavy-duty model? You're in the minority, and you're also out of luck. That's because there are barely any more fullsize vans on the market with gross vehicle weight rating of less than 8,500 pounds, the threshold that separates light- and heavy-duty vans.
According to PickupTrucks.com, neither the Ford E-Series, Ram ProMaster, nor Mercedes-Benz Sprinter are available in light-duty versions. Few of the Ford Transit configurations are, either, and now General Motors is discontinuing production of the 1500-series Chevy Express and GMC Savana.
Apparently light-duty versions accounted for just 23 percent of Express sales and only 7 percent of Savanas. Add to that the fact that these 1500 versions were the only ones using the old generation of engines and suspension, and that the Wentzville plant near St. Louis, Missouri, is trying to make room for the next Chevy Colorado and GMC Canyon pickups, and the fate of the light-duty GM van was sealed.

GM expanding Lansing Lambda CUV plant

Considering that crossovers are a rapidly growing portion of the US auto market, it's not surprising to hear that General Motors is preparing to build even more of them. The company is investing $63 million to expand its Lansing Delta Township Assembly plant that builds Lambda platform CUVs like the Chevrolet Traverse, GMC Acadia and Buick Enclave.
According to GM, the expansion will add roughly 263,000 extra square feet of space to the plant. Of that, 181,000 square feet will be for an updated body shop with cutting-edge robots. There will also be 54,000 square feet of additional room in the paint shop and 28,000 square feet of more area for general assembly.
GM isn't saying as much, but there is the possibility that this extra space could allow for additional models produced at the factory. Cadillac reportedly dropped plans to build a three-row SUV on the Lambda platform earlier this year, however, dealers for the luxury brand were recently pitched the possibility of adding large and small CUVs, an ATS convertible or a sedan below the ATS.
