Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.

2016 Chevy Volt arrives with 50-mile EV range, 41 mpg [w/ video]

Let's start with the numbers. The 2016 Chevy Volt will have an all-electric range of 50 miles from a new, 18.4-kWh lithium battery. It will get 41 miles per gallon (combined) once the battery runs dry and have 102 MPGe. Oh, and it has five seats, sort of. To compare, today's four-seat 2015 Volt has a 38-mile range from a 17.1-kWh battery in a powertrain that offers 37 mpg and 98 MPGe. So, across the board, there are notable improvements. Now that that's out of the way, let's talk story. General Motors will unveil the new Volt at the Detroit Auto Show later today, but it's been talking about how this new version – the first major plug-in hybrid vehicle to get a serious redo in the modern era – was crafted with reams and reams of data from first-gen Volt customers. At a preview event for journalists last week, GM executive chief engineer Pam Fletcher told Autoblog that these owners "gave us the recipe" to make the second-gen model. At the top of the request list was more range (check), more "fun-to-drive" behavior (check?) and a smoother and quieter experience (we'll assume a check here, given that the new 1.5-liter four-cylinder – the first North American application of this new engine family – should offer more power with less noise than the previous 1.4-liter, four-cylinder powerplant). Other customer-driven changes in the new Volt include a different place to store the charging cable (in the side of the trunk instead of under the load floor) and a new brake system with improved blended regenerative braking feel as well as driver-selectable regen levels. The requested 50-mile range comes from a new, lighter battery that has increased capacity from fewer cells (192 vs. 288) and a simplified control architecture. Along with the new battery, the electric drive unit is a two-motor deal that is up to 12 percent more efficient and 100 pounds lighter, while also being "tremendously smaller," notes Fletcher. It offers 294 pound-feet of torque and a maximum 149 horsepower of "motoring power" delivered to the wheels. GM says it has worked hard to reduced the amount of rare earth materials in these motors, and one of them doesn't use any at all. The new powertrain offers improved acceleration times, as well. The 2016 Volt can go from 0 to 60 miles per hour in 8.4 seconds, a seven-percent improvement, while the 0-30 mph time has been improved by 19 percent, down to 2.6 seconds. The new Volt is more conventional looking, but certainly not completely ordinary.

Even if GM does close all 5 of those plants, it'll still have too many

DETROIT — General Motors' monumental announcement on Monday that it will close three car assembly plants and two powertrain plants in North America and slash its workforce will only partially close the gap between capacity and demand for the automaker's sedans, according to a Reuters analysis of industry production and capacity data. Sales of traditional passenger cars in North America have been declining for the past six years and are still withering. After GM ends production next year at factories in Michigan, Ohio and Ontario, it will still have four U.S. passenger-car plants — all operating at less than 50 percent of rated capacity, according to figures supplied by LMC Automotive. In comparison, Detroit-based rivals Ford and Fiat Chrysler Automobiles will have one car plant each in North America after 2019. The Detroit Three are facing rapidly dwindling demand for traditional passenger cars from U.S. consumers, many of whom have shifted to crossovers and trucks. Passenger cars accounted for 48 percent of retail light-vehicle sales in the United States in 2014, according to market researchers at J.D. Power and Associates. This year, sedans will account for less than a third of light vehicle sales. That shift in turn has left most North American car plants operating far below their rated capacities, while many SUV and truck plants are running on overtime. The collapse in passenger-car demand is a challenge for nearly all automakers in the United States, including Japan's Toyota and Honda, which have the top-selling models in the compact and midsize car segments. Toyota executives said last month they are evaluating the company's U.S. model lineup. But Toyota also plans to build compact Corolla sedans at a new $1.6 billion factory it is building in Alabama with partner Mazda. The obstacles facing GM in its plans to close more auto factories became apparent on Tuesday as U.S. President Donald Trump threatened to block payment of government electric vehicle subsidies to GM. While it is not certain that Trump unilaterally has the power to do that, he made it clear he intends to use his office to pressure the company to keep open a small car plant in Ohio that GM says will stop building vehicles in March.
