Ford Police Interceptors dominate Michigan State Police testing

Once again, Ford Motor Company builds the fastest police vehicles. The Blue Oval touted the news in an official release following Michigan State Police and Los Angeles County Sheriff's Department testing. Ford did very well. Except for one acceleration metric – zero to 10 miles per hour – the Blue Oval's Taurus and Explorer-based cop cars were the quickest, with particular praise coming for the EcoBoost-powered models, which bested Chevrolet and Dodge's V8-powered variants. Dearborn's products also posted the fastest average times around MSP's vehicle dynamics course. But it wasn't all positive for Ford. The only four-cylinder in the contest, the 2.0-liter, EcoBoost Ford SSP Sedan, had both the lowest top speed, 120 mph, and the slowest acceleration figures. It was also the slowest in track testing. Ford's products also failed to match the braking and top speeds of its rivals from Detroit and Auburn Hills – the rear-drive Charger Pursuit posted the best braking stats of the entire test, while the V8-powered Chevrolet Caprice hit the highest top speed, at 155 mph. Ford did score a top speed award, among SUVs, but at 132 mph, the naturally aspirated Police Interceptor Utility had to share its award with the equally fast, rear-drive Chevrolet Tahoe. The LA County Sheriff's timing isn't publicly available, but according to Ford, the EcoBoost-powered police cars put on a similarly impressive show for cops on the West Coast. We've assembled a spreadsheet on Google Docs that offers an easy to browse comparison of the different stats assembled by the Michigan State Police, and divided the vehicles between standard V6-powered sedans, high-performance sedans (EcoBoost and V8 models), and SUVs.

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.

GM to cut production at 5 plants in North America, kill several models

DETROIT/WASHINGTON — General Motors Co said on Monday it will cut production of slow-selling models and slash its North American workforce in the face of a stagnant market for traditional gas-powered sedans, shifting more investment to electric and autonomous vehicles. The announcement is the biggest restructuring in North America for the U.S. No. 1 carmaker since its bankruptcy a decade ago. GM said it will take pre-tax charges of $3 billion to $3.8 billion to pay for the cutbacks, but expects the actions to improve annual free cash flow by $6 billion by the end of 2020. GM plans to halt production next year at three assembly plants: Lordstown, Ohio, Hamtramck, Michigan, and Oshawa, Ontario. The company also plans to stop building several models now assembled at those plants, including the Chevrolet Cruze, the Cadillac CT6 and the Buick LaCrosse, the sources said. Sources said the Chevrolet Volt, Impala and Cadillac XTS would also be discontinued. Signs of the demise of six passenger-car models have been swirling since July. Plants in Baltimore, Maryland, and Warren, Michigan, that assemble powertrain components have no products assigned to them after 2019 and thus are at risk of closure, the company said. It will also close two factories outside North America, but did not identify those plants. The AP reported that 14,700 jobs would be affected. Some 8,100 of those would be white-collar jobs reduced through buyouts or layoffs. The No. 1 U.S. automaker signaled the latest belt-tightening in late October when it offered buyouts to 50,000 salaried employees in North America. The company also said it will cut executive ranks by 25 per cent to "streamline decision making." Some 6,000 factory workers could lose their jobs or be transferred to other plants. Its shares were last up 6.2 percent at $38.16. Tariff 'headwinds' and cost-cutting GM Chief Executive Officer Mary Barra told reporters on Monday the company can reduce annual capital spending by $1.5 billion and increase investment in electric and autonomous vehicles and connected vehicle technology because it has largely completed investing in new generations of trucks and sport utility vehicles. Some 75 percent of its global sales will come from just five vehicle architectures by early in the 2020s. It plans to reduce annual capital spending to $7 billion by 2020 from an average of $8.5 billion a year during the 2017-2019 period.
