Mercedes F1 to use Qualcomm 5 GHz WiFi for its tire data

In Formula 1 you need more of everything. More speed, more grip, more hospitality, more money. And you need data, reams and reams of data. The Mercedes-AMG Formula 1 team – the guys with the silver cars driven by 2015 F1 champion Lewis Hamilton and his teammate Nico Rosberg – need so much information that they've teamed with Qualcomm to wirelessly upload thermal imaging data of its tires. During a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Live telemetry has been a feature of Formula 1 for 20 years, though there are more restrictions on it than in the past. (In the days leading up to last weekend's United States Grand Prix in Texas, Formula 1 major domo Bernie Ecclestone said that F1 needs to cease being an engineering war and return more responsibility to the drivers.) Nevertheless, F1 teams gather vast amounts of data during a race weekend, particularly in practice sessions during which restrictions on what they can upload from cars – from engine/power unit parameters to aerodynamic loads – are less prohibitive. For example, during a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Mercedes F1 technical director Paddy Lowe points out that the standard telemetry system simply doesn't have the bandwidth to handle the thermal tire imaging data that the onboard thermal cameras generate. Why do you want a thermal video of the tires? Because it tells the engineers and drivers precisely how much temperature there is across the surface of a tire during a lap, in corners and on the straights. It also indicates how quickly the tires come up to temperature and when they potentially overheat. Understanding the temperature variations allows the team to set the cars up optimally for grip and tire life during a stint. Qualcomm's system works with the race cars like this: Each car has forward- and rear-facing cameras in a winglet mounted on the left side of the engine intake behind the driver's head, which continuously record thermal images of the tires. As a Mercedes enters the pit lane, it passes a Qualcomm 802.11ac WiFi receiver to which it uploads the thermal data. As the car nears the garage, another receiver takes over the upload. Several Qualcomm Snapdragon 805 processors crunch the raw data as it uploads. The data is encrypted – there are always prying eyes in Formula 1.

Which car should win 2015 World Green Car of the Year?

There were three finalists for the World Green Car of the Year announced about a month ago at the Geneva Motor Show: the BMW i8, the Mercedes-Benz S 500 Plug-In Hybrid and the Volkswagen Golf GTE. With the New York Auto Show upon us and the winner scheduled to be announced tomorrow, we thought it's high time to ask our readers which one should win. There were seven other vehicles named to the finalists list: the Hyundai x35/Tucson Fuel Cell, the Volvo XC90 T8 Twin Engine, the Audi A3 Sportback E-Tron, the BMW X5 xDrive40e, the Kia Soul EV, the Nissan e-NV200 and the Opel Adam 1.0 Direct Injection Turbo ecoFLEX Start. Would you have named one of these to the top three list instead? POLL 14386429 Green BMW Mercedes-Benz Volkswagen 2015 ny auto show world green car of the year vw golf gte

Workers at Mississippi auto supplier protesting low wages

Workers at an automotive seat factory in Mississippi are protesting what they say are low wages and poor working conditions as they attempt to unionize in what could become a new front for the United Auto Workers in the state. A group of workers and supporters at the Faurecia SA seating plant in Cleveland plans a Tuesday march. "We work an auto job and we're getting paid like Wal-Mart wages," said Jamarqus Reed, a 32-year-old Pace resident who has worked at the plant for almost 10 years. "We're trying to better ourselves." Nationally, the UAW has staked its future on unionizing Southern auto factories, with limited success so far. The union has been trying to organize Nissan Motor Co.'s Canton, MS, plant for years, and lost a 2008 worker vote at a Johnson Controls plant in nearby Madison that French-based Faurecia bought in 2011. The UAW narrowly lost a unionization vote at the Volkswagen AG plant in Chattanooga, TN, last year, but the union has since qualified for a new labor policy at the plant that grants access to meeting space and to regular discussions with management. The policy stops short of collective bargaining rights. The union is also trying to organize Nissan's assembly plant in Smyrna, TN, and Daimler AG's Mercedes-Benz plant in Tuscaloosa, AL. Protesters say Faurecia employees make a top wage of $11.64 per hour, while contract workers make $7.73 an hour. Company spokesman Tony Sapienza said that with overtime, the typical Faurecia employee makes more than the $27,000 a year that is the median wage around Cleveland. Wages are often low in the heavily impoverished Delta. "We are very confident that we are offering a very competitive wage," Sapienza said. Organizers criticize use of lower-paid contract workers Shannon Greenidge, a 44-year-old Cleveland resident, said she worked for a labor agency for more than two years before being hired directly by Faurecia. Greenidge said she makes $9.29 an hour, and can't save for retirement or to send her 11-year-old daughter to college. "That's not going to help me down the line in life," she said. Union supporters say as many as half the workers at the plant work for a contract-labor agency. Sapienza said that while the number varies, the company expects 15 percent of its workforce will be temporary employees this year. The UAW has organized some Southern auto parts plants in recent years, including Faurecia plants in Cottondale, Alabama, in 2012 and Louisville, Kentucky in 2013.
