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.

Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.

Weekly Recap: BMW rolls out ambitious plug-in hybrid electric plan

"We believe that for the United States, this is going to be very important." – Julian Arguelles Let there be no doubt, BMW is serious about electric vehicles. The German automaker said this week it will make plug-in hybrid versions of all of its core models, an aggressive move that demonstrates its commitment to electric propulsion systems. BMW did not specify which vehicles will get the plug-in systems or provide a timeline for when they will arrive. But the announcement is clearly more than blustering, and the company revealed a 3 Series plug-in prototype this week at an event in France. BMW said the 3 Series uses a version of its 2.0-liter turbocharged four-cylinder engine (240 horsepower, 300 pound feet of torque) with an electric motor sandwiched between the engine and transmission in place of the torque converter. It has an all-electric range of 22 miles. A plug-in X5 with the same powertrain was also displayed alongside the 3 Series, though the X5 has been on the auto-show circuit for more than a year, including a recent stop in Los Angeles. Those two vehicles use "eDrive," and BMW's plans represent the first widespread transfer of its technology from development of the i3 and i8 models to more mainstream products. BMW said it's developing electric powertrains so they can be deployed rapidly across its range, and they are flexible enough to be used with fuel cells in future products. Enticingly, BMW is also working on a "Power eDrive" system, which debuted in a 5 Series GT concept at the event in France. This setup has two electric motors powered by a 20-kilowatt-hour battery pack, and when teamed with a four-cylinder turbo, pump out about 670 hp. Reinforcing BMW's commitment, the company will add more than 200 jobs at its factory in Dingolfing, Germany, to support electric-vehicle development. The moves come as BMW and other automakers diversify their portfolios while fuel economy and emissions regulations are getting tighter around the world. The United States has set a 54.5-mpg CAFE requirement for the 2025 model year. BMW said the electric vehicles were developed with an eye toward the US market, its government policies and its wide-ranging commuting styles. "We believe that for the United States, this is going to be very important," spokesman Julian Arguelles said. Ben Scott, a senior analyst in London with automotive research firm IHS, said BMW's moves are expensive – but necessary – to keep pace with the market.
