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's Buckle to Drive teen safety feature comes to more models for 2021

In 2014, GM announced a feature called "Belt Assurance," which would prevent a vehicle from being shifted out of park until the driver and front passenger had buckled their seatbelts. Initially launched on certain fleet vehicles in 2014, the feature rolled out as a free option on the 2015 GMC Sierra, Chevrolet Colorado, Cruze and Silverado. At the time, GM said it would push Belt Assurance to more models if customers took to it. That appears to have happened; come 2019, GM repackaged Belt Assurance as Buckle to Drive, part of the automaker's Teen Driver System that bundled tech such as geofencing and speed limit warnings to help parents keep track of their children's driving habits. In that implementation, the system only works when Teen Driver Mode is activated, locking out the shifter and muting the radio for 20 seconds or until the seatbelts are buckled, whichever comes first. The system shows a visual warning in the gauge cluster, too.  For this model year, the Teen Driver System came standard on 10 Chevy models, but Buckle to Drive was only allotted to the Colorado, Malibu and Traverse. Later this year, the 2021 Camaro will join the Chevys outfitted with the Teen Driver System and will get Buckle to Drive in addition. GM Authority reports that for the 2021 model year, Buckle to Drive will also be picked up by the Cadillac CT4 and CT5. Previously, the Cadillac ATS, CTS, Escalade and XTS came with the Teen Driver System, but three out of those four vehicles are no more, and the 2021 Escalade makes no mention of the Teen Driver System nor Buckle to Drive among its safety features. Elsewhere around the GM empire, the Buick Envision and Encore GX include the Teen Driver System, as do six GMC vehicles, but it's not clear when any will be upgraded with Buckle to Drive. The tech could help save numerous teenagers' lives. On its page of teen crash facts, the Centers for Disease Control and Prevention writes that roughly 300,000 teens between the ages of 16 and 19 ended up in emergency rooms to treat crash injuries in 2017. Furthermore, "only 58.8% of high school students always wore seat belts when riding as passengers," and, "Among young drivers aged 15-20 who died in car crashes in 2017, almost half were unrestrained at the time of the crash (when restraint use was known)."

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises.
