2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

Meet the Greenest and Meanest vehicles of 2016

If you've been keeping track, you won't be surprised with the number one entry in this year's list of greenest cars from the American Council for an Energy-Efficient Economy (ACEEE). In fact, the top three spots on the 2016 list are all the same as they were in 2015. After that, things get interesting. For one thing, this is the first Greenest list that doesn't have any purely internal combustion engine powertrain on it. Hybrids, yes, but if you want to be one of the top 12 greenest cars this year, you'd better have some sort of electric angle. ACEEE says that the conventional, gas-powered Smart Fortwo and Chevrolet Spark just missed the cut. In a statement, ACEEE lead vehicle analyst Shruti Vaidyanathan said, "The 2016 scores are in, and plug-in electric vehicles are outpacing all other vehicle offerings in terms of environmental friendliness." Like last year, one of the noticeable vehicles missing from the green list is the Tesla Model S. One reason? ACEEE takes curb weight into account (lighter is better), and the Model S is a heavy beast. The ACEEE doesn't just look at the clean side of the ledger. It also puts out a "meanest" list. These are the vehicles that pollute the most, not only from their tailpipes, but also any pollution created during the entire manufacturing process, from mining the raw materials to the energy used to produce the vehicle at the factory. The entire list, from greenest to meanest, is done using a "cradle to grave" analysis.

Today at greenercars.org, the American Council for an Energy-Efficient Economy (ACEEE) released its 19th annual comprehensive environmental ratings for vehicles.

GM admits goal of 500,000 EVs by 2017 won't be met

After a little over four years of Chevy Volt sales, General Motors has a better handle on how many people it expects will buy cars with plugs. And it's less than the company thought back in 2012, when then-senior vice president of global product development, Mary Barra, said that GM expected to sell 500,000 "vehicles with electrification" by 2017. In a sustainability report released this week, GM says that half-million vehicle target will not be met but that it still, "believes the future is electric." In the report, GM says that, "For our commitment to electrification, our forecasted outlook currently projects us, along with the broader automotive industry, falling short of expectations for 2017. ... We continue to aspire to our stated goal." GM's electric lineup includes the Volt, the recently popular Spark EV, the slow-selling Cadillac ELR and upcoming Malibu Hybrid, CT6 plug-in hybrid and eAssist technology in the Buick LaCrosse and Regal. GM says it has 180,834 electrified vehicles on the road in the US today. In 2013, it had 153,034; 95,578 in 2012, and 39,843 in 2011. The company's next big plug-in vehicle will be the second-gen Chevy Volt, which is coming to market later this year, followed by the 200-mile Bolt EV coming, we think, in 2017. GM Employees on Mission to Transform Transportation Sustainability report outlines vehicle and manufacturing progress; sets new targets 2015-05-07 DETROIT – General Motors' just-released sustainability report chronicles efforts by the company's 216,000 employees to live out GM's newly defined purpose and values by earning customer loyalty, applying meaningful technology advances and improving the communities where it does business. These actions – led by CEO Mary Barra – further drive sustainability into the company's culture through building safer and smarter vehicles with less environmental impact. "GM will take a leading role in the auto industry's transformation as it undergoes an unprecedented period of change," said Bob Ferguson, senior vice president, GM Global Public Policy. "From GM's labs to its assembly lines, our people are driving the world to a better place through improved mobility." The company believes the future is electric, with billions of investment to support an all-in-house approach to the development and manufacturing of electrified vehicles. It now counts 180,834 on the road in the U.S – up from 153,034 in 2013.
