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.

2016 Chevy Camaro Convertible gets cleaner looks, improved refinement [UPDATE]

UPDATE: We have live photos from the reveal. Scroll to the bottom of the story and check them out in the Related Gallery. Back in May, Chevrolet introduced a redesigned Camaro. Now, and not at all surprisingly, the Bowtie brand is showing off the latest Camaro convertible, based on the coupe that debuted on Belle Isle in Detroit. From the beltline down, this is the same car that was so well-received last month. But above the waist, there's an all-new, fully automatic canvas roof that can be raised and lowered at speeds up to 30 miles per hour. On top of that, owners will be able to drop the roof remotely by simply pressing a button on the key. Chevy does not, however, say if this new convertible roof is lighter than last year's top. The biggest change for the Camaro convertible, though, is something we've long yearned for – a proper hard tonneau cover that deploys over the folded roof. The current muscle car's roof fabric has the unpleasant tendency to flap in the breeze. The new droptop shouldn't have that problem, and will likely boast an even cleaner top-down profile to boot. Like the hardtop, though, the Camaro convertible does benefit from the same lightweight structure, that helps trim "at least" 200 pounds of body fat. It should also make use of the same powertrain lineup, with a turbocharged four-cylinder, a 3.6-liter V6, and a 6.2-liter V8 with six-speed manuals or eight-speed automatic transmissions spanning the lineup. "From the beginning, the Camaro's architecture was developed to incorporate a convertible with uncompromised driving dynamics," Camaro chief engineer Al Oppenheiser said in the attached release. "Customers will appreciate what they don't feel: quivers, cowl shake or an under-damped chassis typically found in a four-seat convertible." Increased refinement, a cleaner look, better driving dynamics and a more usable convertible roof? We're looking forward to you 2016 Camaro convertible. Chevy claims the new car arrives in "early 2016," which means we should plan on seeing this droptop at the typically cold and snowy Detroit Auto Show. Until then, check out the full press release from Chevrolet.

2021 Chevy Silverado, GMC Sierra fuel economy to go down due to global chip shortage

Production of the 2021 Chevy Silverado and 2021 GMC Sierra is continuing, but the global semiconductor chip shortage is resulting in a mid-year change. Or rather, an omission.  Basically, the availability of cylinder deactivation for the 5.3-liter V8 will be significantly reduced, resulting in a reduction of 1 mpg combined for affected models. This applies whether that engine has the six- or eight-speed automatic, as well as to both the regular Active Fuel Management and the more advanced Dynamic Fuel Management cylinder deactivation systems. DFM does remain with the pairing of 5.3-liter V8 and 10-speed automatic that comes standard on the LT Trail Boss and High Country. "Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed," GM spokesperson Michelle Malcho told Autoblog. She also indicated that the engines will still have the AFM/DFM hardware in place, but that GM will not allow activation of the systems in the future with an ECM change.  Malcho also confirmed to Autoblog that the Silverado and Sierra's other engines will continue to have AFM and DFM, including the 2.7-liter turbo inline-four, 4.3-liter V6 and 6.2-liter V8. In an earlier statement to Reuters, she declined to say the volume of vehicles affected. "By taking this measure, we are better able to meet the strong customer and dealer demand for our full-size trucks as the industry continues to rebound and strengthen," Malcho wrote Reuters in an email. The change runs through the 2021 model year, she said. Malcho told Reuters it would not have a major impact on the Detroit automaker's U.S. corporate average fuel economy (CAFE) numbers. "We routinely monitor our fleet for compliance in the U.S. and Canada, and we balance our portfolio in a way that enables us to manage unforeseeable circumstances like this without compromising our overall (greenhouse gas) and fuel economy compliance," she said. GM's fleetwide fuel economy in the 2018 model year was 22.5 miles per gallon and was projected to rise to 22.8 mpg for 2019, according to a report by the Environmental Protection Agency. To meet federal CAFE requirements, automakers like GM often use credits from either earlier years where they faced less stringent rules and performed better than the requirements or buy credits from other automakers. GM said last month the chip shortage could shave up to $2 billion from this year's earnings.
