Race Recap: 2013 Twelve Hours of Sebring, cakewalk up front, grindfest out back [w/spoilers]

This year's 12 Hours of Sebring wasn't exactly a foregone conclusion because we're still talking about racing, and anything can happen when the speeds are as high as the adrenaline and the desire. But we're still talking about Audi bringing it's two top-spec racers - and its huge budget and its nearly neurotic attention to detail - to a race that it uses as a test bed for The 24 Hours of Le Mans and as a way to open the endurance racing season with a victory.
Besides, 12 hours is a long time, especially at Sebring, and things didn't go all Audi's way. On top of that, although it was a pretty quiet race, behind the Audis things got even grimier, with plenty of battles, plenty of mechanical issues, and the new BMW Z4 GTE and Viper GTS-R being race tested. Oh, and that brand new chromed-out DeltaWing...

GM under fire from safety advocates over braking problem caused by recall fix

Safety experts are lambasting General Motors over what they say is the automaker’s slow notification of owners of certain 2019 sedans and trucks that a recall fix could cause power braking to fail and increase the risk of a crash, the Detroit Free Press reports.  GMÂ’s original recall in December targeted about 550,000 Cadillac CT6 sedans and Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, all from the 2019 model year, over potentially defective electronic stability control and antilock brakes. In that case, GM said the errors would not show up as a diagnostic warning on the instrument cluster. But after GM had done recall work on 162,000 vehicles, about 1,700 owner have complained that their power brakes didnÂ’t work after they had the recall done and then used the OnStar app to start their vehicle. GM then issued a supplemental fix for customers whoÂ’d already had their vehicles serviced. In this case, a diagnostic warning should illuminate saying either “Service Brake Assist” or “Service ECS,” which GM says is a signal that a customer should not drive the vehicle and instead call their dealer, which will tow the vehicle and have it repaired. Safety advocates say the automaker hasnÂ’t gone far enough to protect customers. “The fact that you could potentially start a vehicle and not have brakes is a pretty risky proposition,” Sean Kane, president of the Safety Research and Strategies, which works on auto issues for plaintiffs and governmental organizations, told the Freep. “The fact that they wouldnÂ’t notify owners (sooner) is pretty stunning.” GM told the Freep it was required to notify the National Highway Traffic Safety Administration and file paperwork before it notified customers about the original recall, which was made Dec. 12. It then had to investigate and resolve the problem created by its original recall fix before alerting customers. GMÂ’s call center and dealers are contacting the remaining 900 customers who havenÂ’t yet had the update made to the original recall repair. GM also hired a vendor to send recall letters to the 550,000 customers affected by the original recall notifying them about the update. There are no known injuries or deaths related to the problem.

Recharge Wrap-up: Ford HQ gets giant solar array, Chevy City Express gets 24 MPG city

Ford will be building Michigan's largest solar array at its Dearborn headquarters. With funding from DTE Energy, the solar carport will provide covered parking, as well 30 charging stations for electric vehicles. The array is expected to generate 1.13 million kWh per year for Ford's operations, and offset 794 metric tons of carbon emissions. Read more in the press release below. Chevrolet announced the fuel economy for the 2015 City Express, at 25 mpg combined. The cargo van is rated at 24 mpg in the city, and 26 mpg on the highway. Chevy credits the van's inline four-cylinder engine and continuously variable transmission for its impressive city mileage. For its customers - which are mainly businesses - "The fuel economy of the City Express will help stretch their dollar at the pump and give them the flexibility to invest the savings back into their business," says Chevrolet's Ed Peper. The City Express starts at $22,950. Read more in the press release below. Engineers at the University of Wisconsin have developed an efficient engine that runs on a diesel-gas blend. The engine, which uses a computer to control the blend proportions, is about 15 percent more efficient than the any diesel engine according to mechanical engineering professor Rolf Reitz. The team has put the experimental reactivity controlled compression ignition (RCCI) engine in a demonstration car - a 2009 Saturn. "This vehicle can do 50 miles per gallon," says Reitz, who believes the system could be improved further. Read more at Wisconsin Public Radio. The Southeast Alternative Fuel Conference and Expo will take place in October in Raleigh, North Carolina. Held at the NC Clean Energy Technology Center from October 22-24, the event will feature a variety of exhibitors, speakers and, most importantly, alternatively powered vehicles. "The three day conference will be a one-stop shop for fleet and transportation related decision makers to learn about return on investment, efficiency and alternative transportation fuels such as biodiesel, electricity, ethanol, propane and natural gas," says Anne Tazewell of the NC Clean Energy Technology Center. If you can't make it to Raleigh for the Expo, you can still enter to win a free two-year lease of a Nissan Leaf at the Center's website. Learn more about the event in the press release, below.
