EcoCar2 is on the hunt for a better, cleaner Chevy Malibu [w/video]

The students spent three years transforming an ordinary Chevy Malibu into a revolutionary vehicle. Not far from the building where General Motors once invented the Chevy Volt, a dozen or so college students are standing on the blacktop alongside a test track, watching a professional driver push the limits of a plug-in hybrid car they've built that's far more radical. These students, from Colorado State University, have spent the past three years transforming an ordinary Chevy Malibu into a revolutionary vehicle. At first glance, it still looks like a regular sedan. But under the hood, they've installed a hybrid powertrain that contains both hydrogen and electric power sources. Even by the standards of the Department of Energy competition they're participating in, it's an outlier. That's exactly what they had in mind. "We didn't want to come here and tell them how to build a better Volt," said Tom Bradley, faculty adviser for the Colorado State team. "They already know how to do that. We can tell them how to think about these possibilities in a whole new way." After three years of work, it all comes down to this. The Colorado State team was one of 15 that came to GM's Milford Proving Grounds last week for the final stretch of the EcoCar2 competition, which challenges regular college students who have no automotive experience to do nothing less than reinvent the American car. The teams have come from across North America, and include schools like Ohio State and Virginia Tech that have a long history of participating in similar competitions, and schools like the University of Washington and Embry-Riddle Aeronautical University that are here for the first time. After three years of work, it all comes down to this. The teams have operated 24 hours a day for almost two weeks here at the Proving Grounds, running a gamut of tests that include a 310-point safety inspection, emissions and energy-consumption tests and road tests, in which professional GM drivers ensure they're road worthy. The winning team will be announced tonight in Washington D.C. Revolutionary cars, ordinary package While other green-car competitions encourage extreme designs, this one comes with a somewhat constraining twist: Yes, students must improve fuel economy and reduce emissions, but in the end, they still have to have a car that would appeal to mainstream customers. In practical terms, that means they must keep conveniences like air conditioning and trunk space.

2019 GMC Sierra revealed with CarbonPro bed and new diesel engine

It's only March, and it's already been one hell of a year for trucks. January's Detroit Auto Show saw the reveals of the 2019 Ram 1500, 2019 Ford Ranger and the 2019 Chevy Silverado. The Chicago Auto Show brought new versions of the Toyota Tacoma and Toyota Tundra TRD Pro. Today, we finally got our first look at the Silverado's twin, the 2019 GMC Sierra. The truck features new styling, a new diesel engine and — on the Sierra Denali — a carbon fiber bed. As with every new full-size truck, the Sierra is larger than the outgoing model in almost every dimension, though exact dimensions haven't been revealed. For reference, though, the Chevy Silverado's bed is 7-inches wider than before. The new Sierra grille is more upright than before and features new C-shaped lighting. The Denali gets LED headlights, tail lights and fog lights. Both SLT and Denali trims get unique 22-inch wheels. As we saw in spy photos, the Sierra's interior is mostly just a copy of the Silverado's with some chrome accents sprinkled throughout. If you like the current truck interiors, you'll be pleased with the new model. Those hoping for a wholesale change will be left wanting. The big improvements inside include a full-color heads-up display, trailer hitch assist apps and cameras, and the rear-camera mirror found in models like the Chevy Traverse and Cadillac CT6. Safety and convenience features include a surround-view camera, blind-spot monitoring, pedestrian detection and low-speed automatic braking. Like the Silverado, there's been a significant effort to cut weight in the new Sierra. The 2019 model loses as much as 360 pounds compared to the current truck. It uses aluminum for the doors, hood and tailgate. Steel is still used for the fenders, roof and standard cargo box. The Denali, however, gets the real surprise here. Available only on the top-tier trim, the bed box will be constructed of carbon fiber rather than steel, saving 62 pounds. Carbon fiber only replaces the steel inner panels and floor. GMC says the carbon fiber will also help scratch and corrosion resistance. SLT and Denali models also get a new MultiPro tailgate. This is unique to the Sierra and separate from the Silverado's power assist unit. A new feature that helps one get into and out of the bed using an assist handle. The tailgate step has a maximum weight capacity of 375 pounds. There multiple positions that allow customers to extend the bed, or drop the center vertically to gain easier access to the back.

Nissan Leaf sets new November sales record, Chevy Volt drops again

When you talk to people in the plug-in vehicle industry, one theme you hear repeatedly is that the more plug-in cars that are out there, the better things are for everyone. One reason is that more EVs build a need for more public chargers, and more chargers mean more people see that plugging in is feasible. But there's still something to be said for old-fashioned competition, and in the sales race between the two long-running plug-in vehicles in the US, the Nissan Leaf is resoundingly beating the Chevy Volt for 2014. In fact, it won't be long before the EV's cumulative sales top the PHEV's. But that's a topic for another month. For now, we have the sales results from November. Unsurprisingly, Nissan set another monthly record (that is, the best Leaf sales in any November, the 22nd time in a row we've seen a monthly record) with 2,687 sales last month. That's up 34 percent over last November and up 35 percent year-to-date. Toby Perry, Nissan's director of electric vehicle marketing, said in a statement that, "Our 'Kick Gas' ad campaign and 'No Charge to Charge' launch in Chicago and Atlanta drove an increase in November Leaf sales. Even with gas prices falling across the country, consumers appreciate that the cost of driving a Nissan Leaf is still a fraction of that of a gas-powered car." Over on the Chevy side of the ledger, there were 1,336 Volt sales last month, down 30.4 percent from the 1,920 sold in November 2013. So far this year, Volt sales are down 16.4 percent and Chevy has sold 17,315 Volts in 2014. As we said last month, the Volt slump might be due to people waiting on the new version to make an appearance at the Detroit Auto Show next month before going on sale in the second half of 2015. So far in 2014, Nissan has sold 27,098 Leafs. Look for our detailed post of US green car sales in the near future. Until then, please discuss last month's Leaf and Volt sale in the comments, below.
