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.

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events."

No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.

Car Club USA: Louisiana Mudfest

There's nothing quite like mudding. Big tires, huge power, and crazy-wild gearheads that like to throw down on a mud pit almost as much as a thirty rack of Coors. In the latest, and some might argue greatest yet episode of Car Club USA, we head to Louisiana to throw some dirt at Mudfest. As Louisiana's one and only Mouth of the South puts it, "If you don't mud ride... go to Texas I guess." Joining The Mouth and friendly rivals The Most Hated Mud Sluts, we dive in. Beyond the obvious V8 blasting and tractor-tire spinning, those who know best describe Mudfest as, "Good cooking, good friends, good fun, and a lot of partying." It's a motorsport spectacle unlike any you're likely to find up North or out West, though no less impressive to behold. Follow along with the fun, the impromptu drag racing, the trash talking, and the mechanical madness. And find out why, at Mudfest, "if we don't tear it up, we ain't done it right." Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.
