Pics Aplenty: Meet the 2014 Chevrolet Silverado and GMC Sierra [w/poll]

Today was a pretty big day for General Motors, debuting the all-new Chevrolet Silverado and GMC Sierra light-duty pickup trucks ahead of their official showcase at the 2013 Detroit Auto Show. And now that the dust has settled at GM's big reveal event, we've had a chance to snap dozens of photos of the new pickup pair from every angle.
We already told you the important bits earlier today (click here in case you missed it), but let's recap. Under the hood are three new engines - a 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 (you know, a version of the small-block that'll also be found under the hood of the C7 Corvette), all mated to six-speed automatic transmissions. The 2014 model year marks the return of the Z71 off-road package with Rancho shocks, front tow hooks and beefier underbody protection. Inside, there's a host of new technology and a greater focus on better quality and refinement.
Some of the nitty-gritty specifics (like engine output numbers and fuel economy) have yet to be revealed, and since we haven't driven the finished products yet, it's hard to say how these trucks will fare against rivals like the Ram 1500 and Ford F-150. For now, we can only judge these two books by their covers, and while we do like the designs of the new trucks, we Autoblog staffers are torn on exactly which one looks best.

2016 Chevy Volt powertrain technical details

The last time General Motors launched a Chevy Volt, it was operating without really knowing how people would use the plug-in hybrid. Sure, it had experience with the EV1, but the Volt was a new kind of car, and you can see in the archives just how much time GM spent explaining this fresh, new powertrain to potential customers. Then, once the vehicle was released, the company collected voluntary data from a large number of owners to learn about their driving and charging habits. The company also asked them what they wanted most in the new version. There's got to be an algorithm buried somewhere in GM headquarters that was used to take all of the numbers GM collected and spat out the headline figures for the 2016 Volt: 50 miles of EV range and 41 miles per gallon. Another important number – price – is something GM isn't talking about yet (expect it in April or May), but the company is sharing some powertrain details about the upcoming car. At a preview lunch in Detroit last week for the SAE 2015 Hybrid & Electric Vehicles Technologies Symposium that's happening now in California, GM engineers Peter Savagian (who is presenting a paper on the new inverter used in the updated Volt) and Tim Grewe (talking about the entire second-generation powertrain) sat down with AutoblogGreen to tell us about the Volt's all-new propulsion system: The overall gist is that the new Voltec 5ET50 drive unit is lighter, smaller and more powerful thanks to a redesigned two-motor traction drive. As previously reported, the new engine is a 1.5-liter DOHC four-cylinder that offers 101-horsepower (at 5,600 RPM). Grewe said it's "great for range extension." The electric motor side of the powertrain offers 149 motoring horsepower from a two-motor, continuously variable transaxle. Initially, the new engine will be made in Mexico. GM will move production to Flint, MI during the first year it makes the 2016 Volt. The battery is slightly bigger in the new Volt – 18.4 kWh compared to 16.5 in the current-gen – and will have less range variation in the cold. GM is also using more of the overall capacity in the pack in the 2016 Volt than in previous versions, but is not saying how much more. GM is not ready to publish acceleration times just yet, but the 2016 Volt has improved numbers, especially when going from 30-60 miles per hour. Most everything on the new powertrain has become more efficient compared to the first-gen Volt.

A Chevy Camaro hybrid? That's what EcoCAR3 could bring

Figuring out a way for a hybrid powertrain to co-exist with the performance expectations of a classic American muscle car is a challenge that could vex that most experienced of automotive engineers. It's a challenge, in fact, being handed to a bunch of college students. Over the next four years, students from 16 North American colleges and universities will attempt to wring fuel efficiency from a 2016 Chevy Camaro as part of EcoCAR3, an advanced-vehicle technology competition sponsored by the Department of Energy, General Motors and others. They'll be attempting to use hybrid or plug-in hybrid technology while not sacrificing the performance of the Camaro, which was selected in part because the current model achieves just 17 miles per gallon in city driving and 28 MPGs on the highway, per EPA numbers. Students will get the latest version of the vehicle to work on, one that is expected to be unveiled next month on Belle Isle in Detroit. "If we still want to produce V8 Camaros, we're going to have to look at alternative methods of propulsion," said Al Oppenheiser, the chief engineer on the Camaro. "So the ideas that these college teams come up with could very easily be adapted to a car like the Camaro." Unlike similar competitions that reward fuel efficiency in vehicles, EcoCAR seeks those gains while emphasizing cost and consumer acceptance of these vehicles. The cars shouldn't look like experiments; they should look like everyday vehicles on the road. Previous competitions have allowed the teams to use whatever powertrain they desired. This time, EcoCAR officials designed the competition to concentrate on hybrid, hybrid-electric and diesel options. Competitors won't have the option of using hydrogen fuel cells as they have in the past. Last year, a team from Colorado State built a vehicle that contained both hydrogen and electric power sources. This year's limit is a curious choice, as some automakers such as Toyota have placed heavy bets on fuel cells in recent years. General Motors also runs a fuel-cell program. With the focus on cost and practicality, however, the program officials wanted to narrow the framework of the contest. "We always have some good decisions on what to make within the scope or out of scope," said Jim Kolhoff, global director of software engineering for General Motors.
