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.

Hertz and GM team up to put 175,000 rental EVs on the road

Hertz and General Motors have announced a significant partnership that will send up to 175,000 electric vehicles into rental fleets across the country. The deal will unfold over the next five years and include vehicles from all GM brands.   The partnership will run through 2027. Hertz estimates that the electric fleet can save as many as 8 billion gasoline-powered miles, removing 1.8 million metric tons of carbon dioxide-equivalent emissions from the air. Hertz says it will invest in becoming the largest renter of EVs in North America and notes that it already has tens of thousands available at 500 locations in 38 states. By the end of 2024, it plans to electrify a quarter of its fleet. Electric rental cars are a great way for travelers wanting to avoid gas, and they make excellent urban commuter cars. Hertz will also likely save a few dollars by avoiding oil changes and other routine maintenance that gas engines need. However, a hidden societal benefit of this deal may come when Hertz’s EV rental customers begin shopping for new cars. Many people are skeptical of EVs for various reasons, including range, charging, ease of operation, and cost. Giving people a low-risk introduction to EVs and the ability to test-drive one without a pressuring salesperson could drive more people to electrics. At the same time, there's also the risk that renters wanting to take their Hertz-GM EV on a road trip into sparsely populated areas may return with charging and range-related horror stories. Hertz currently doesnÂ’t ask what youÂ’re planning to do with your rental, but it does offer a chat service for questions, and range information is presented clearly on each vehicle.

New recall issued in 2019 Chevy Silverado and GMC Sierra brake software saga

General Motors (GM) has issued a new recall for select 2019 Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks that aims to resolve a faulty fix for a previous recall. According to National Highway Traffic Safety Administration (NHTSA) campaign No. 20V055000, a software update for the Electronic Brake Control Module (EBCM) could cause the electronic brake assist to be disabled.  The NHTSA first launched a recall for 463,995 Silverados, Sierras, and Cadillac CT6es on December 12, 2019 due to a software issue in the electronic brake control module (EBCM) that could disable the electronic stability control (ESC) and anti-lock braking system (ABS). As a response and resolution to that recall, GM began to reprogram the software in affected vehicles. GM later learned that the fix was creating a different problem. The installed software had its own error that was disabling the electronic brake assist. If customers see “Service Brake Assist” or “Service ECS" diagnostic warnings, they should park the vehicle and have it towed to a dealership, GM warns. While GM was going through the process of testing, pinpointing the issue, determining action and working with the NHTSA, safety experts have criticized Chevrolet and GMC for not reacting promptly and appropriately.  According to the recall, 148,055 are now affected, all of which do not meet the standards of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control" and 135, "Light Vehicle Brake Systems." To fix the braking issue, GM will once again reprogram the software. GM began notifying owners of the recall on February 10, 2020. Related Video:
