Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.

Recharge Wrap-up: Long Beach ePrix, London's new electric buses

London will put 51 new electric buses into service. With the addition of these buses, two more routes (in addition to one already in operation) will be all-electric. Transport for London plans to have all of central London's 300 single-decker buses running on electricity or hydrogen by 2020. "The expansion of London's electric bus fleet demonstrates our commitment to reducing emissions from public transport in London," says Deputy Mayor of London for Environment and Energy, Matthew Pencharz. "The Ultra Low Emission Zone that will be introduced in 2020 is the most ambitious measure of its kind taken to tackle air pollution anywhere in the world, and it will transform our bus fleet into a cleaner, greener and more pleasant way of travelling for Londoners."

Along with 10 Cruze vehicles, one 2015 Volt has been recalled because of a tie rod that might not have been tightened to the steering gear correctly, which could lead to a loss of steering control. Chevrolet will replace the steering gear assembly, supplied by Robert Bosch Automotive Steering, for free. There have been no reported injuries from this issue. Read more at Detroit News. The Formula E Long Beach ePrix will take place on April 2, 2016. For the second season of the electric racing series, Long Beach is the only confirmed US host, as the spot on the calendar previously held by Miami still remains to be determined. More than 20,000 fans attended the inaugural Long Beach ePrix earlier this year, where Nelson Piquet, Jr. took first place before going on to win the Drivers' Championship. "It's extremely exciting to welcome the ePrix back to Long Beach for a second year," says Long Beach Mayor Robert Garcia, "and we are hopeful that this demonstration of innovation, sustainability, and cutting edge technology will return to our city year after year."

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.
