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.

GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.

2022 GMC Yukon gets larger screen, standard power sliding console

The 2022 GMC Yukon is falling into line with its big SUV siblings, the Chevrolet Tahoe and Suburban, according to a rundown of new features on Muscle Cars & Trucks. We've already covered the availability of the 6.2-liter V8 on the AT4 trim, and it looks like GMC buyers will have an easier time of it than Chevy buyers who want the 6.2, the engine looking like a standalone option on the GMC.  Inside, the Yukon welcomes the 12.3-inch digital gauge cluster, replacing the previous eight-inch cluster that had an analogue tach and speedo. A little to the right, the infotainment system will come with Google Automotive built in, obviating the need to pull up Android Auto to get access to Google Maps, Google Assistant, and the Google Play Store. And just below that, the Yukon Denali makes the power sliding console a standard feature instead of a $350 option.  The big V8 with 420 horsepower and 460 pound-feet of torque comes with a shiny pair of exhaust finishers, plus 2022 sees the addition of Redwood Metallic paint, some new wheel options, and rocker panels that can be gussied up with illuminated sill plates. The current Yukon offers Max and ProGrade trailering packages, for next year an Enhanced Trailering Technology Package adds a 13-camera trailering bundle with the option for an interior accessory camera for those with enclosed haulers. On the safety side, expect reverse automatic braking to join the list of available driver assistance features. Related Video This content is hosted by a third party.
