Expect greater differentiation in GM's next-generation SUVs

General Motors says its next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade models will offer shoppers improved interior differentiation. Car and Driver recently caught up with Chris Hilts, GM's creative manager of interior design, who said that the cabins will all feature unique instrument panels, consoles, center stacks and switchgear moving forward. Apparently GM is now aware that consumers may be bothered by the fact that today's $85,000 Escalade has effectively the same cabin as a $45,000 Tahoe. Hilts says SUV buyers want more refinement than their pickup purchasing counterparts - and those same buyers also want their SUVs to have more exterior differentiation between the company's Silverado and Sierra pickup lines. Shocking.
That all sounds good to us, but we've heard this song and dance before. GM made big waves about how different the new-for-2013 Silverado and Sierra would look from each other, but judging by what we've seen so far, GM's stylists are painting in shades rather than with the full spectrum.

GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

Who sold the most heavy-duty pickups in 2012? PickupTrucks.com investigates

Domestic manufacturers enjoyed a good year for heavy-duty pickup sales in 2012. PickupTrucks.com has taken a close look at exactly how those sales broke down between each manufacturer and between three-quarter and one-ton pickups. Ford sold some 67,786 F-250 Super Duty models last year with the Chevrolet Silverado 2500 HD falling just behind at 56,359 units. The Ram 2500 HD came in third at 41,918, while the GMC Sierra 2500 HD earned itself fourth place with 27,616 deliveries. While Ford held onto the top spot in the one-ton market, Ram easily nailed down second place by selling more 3500 HD models last year than General Motors sold Silverado 3500 HD and Sierra 3500 HD trucks combined.
So, did GM manage to sell more trucks than Ford with its two brands? Very nearly. Ford sold a total of 119,338 heavy-duty pickups to GM's 111,555. Ram, meanwhile, moved a distant 77,583. But perhaps more interesting is the diesel take rate in this segment. PickupTrucks.com says 80 percent of all domestic one-ton trucks roll from the dealer lot with a turbo-diesel under the hood.
