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.

Mercedes-Benz, Volkswagen, and Audi announce Takata recalls

Daimler, Volkswagen, and Audi will recall nearly 1.7 million total vehicles in the US to replace their Takata airbag inflators. The Japanese parts supplier and the National Highway Traffic Safety Administration announced in late January that several automakers would need to fix around five million more vehicles, and the various companies have been releasing the details since then. Daimler has a recall for 841,000 vehicles in the US, including 705,000 from Mercedes-Benz and 136,000 from the company's van division. Reuters reports the affected models consist of 2005-2014 examples of the SLK-Class, C-Class, E-Class, M-Class, GL-Class, R-Class, and SLS-Class. The vans comprise the 2007-2014 models of the Dodge, Freightliner, and Mercedes Sprinter. Autoblog reached out to Mercedes USA to confirm these details, and we're awaiting a reply. Daimler expects the repair campaign to cost 340 million euros ($382 million at current rates). The company will book the costs as part of its financial year 2015 results, and net profit for that year will fall to 8.7 billion euros ($9.8 billion). Volkswagen's recall covers 680,000 vehicles in the US to replace their driver side airbags. The affected models have Takata's SDI and PSDI-5 inflators, which could rupture in an crash, but the automaker isn't aware of any explosions for these parts in its products. This campaign includes: 2006-2010 Passat Sedan and Wagon (German Production) 2012-2014 Eos 2010-2014 Golf 2010-2014 Jetta SportWagen 2012-2014 Passat (U.S. Production) 2009-2014 CC There are also 170,000 Audi vehicles with the SDI and PSDI-5 inflators in the US, but there are no reports of the parts rupturing in the company's models. The affected products are: 2005-2013 A3 2006-2009 A4 Cabrio 2009-2012 Q5 2010-2011 A5 Cabrio VW and Audi are still working to identify the specific VINs for these vehicles. Afterwards, they will notify affected owners. Ford, Mazda, and Honda already announced details for their new round of Takata repairs. VW and Audi also recalled a small number of Tiguans and Q5s to replace their side airbag inflators from the Japanese company. NHTSA still expects BMW and Saab to detail expanded safety campaigns.

Aston wants to build DBX on its new platform, not Mercedes'

Aston Martin is proceeding with plans to launch the DBX as its first production crossover. It just can't say at this point what it will be based on. Speaking with Automotive News Europe, Aston's new CEO Andy Palmer indicated that basing the DBX on a Mercedes SUV platform would not be its first choice because they "clearly sit in a very different space to the one we want to go" with the DBX. Instead, the company's first choice would be to build the crossover atop the new platform it's developing for its sports cars. "It just depends how high off the ground it could go," said Palmer. "I don't exclude the possibility of using some [Mercedes] parts, but I would say very much the primary route is our platform." The prospect of building an Aston SUV on Mercedes architecture – namely that of the GL-Class – has been on the table for some time now. The Lagonda SUV concept it showcased at the Geneva show in 2009 was based on the GL, and the two automakers have been forging a tightening alliance in the years since. The British automaker's next-generation engine is to be built by Mercedes-AMG, and it is expected to source other components from the German automaker as well. For its part, Mercedes has been taking a sportier approach with its latest crossovers, as demonstrated by the GLE Coupe that debuted before the more conventional version and the Concept GLC Coupe that previewed the GLK's replacement in Shanghai last month. Aston Martin, on the other hand, is building a new sports car platform that will underpin its next generation of luxury GTs, replacing the long-serving VH architecture that has served for decades as the basis for its entire model line. Perhaps the most surprising of ANE's report, though, is that Aston seems to be proceeding with plans to build the DBX apparently without even knowing what platform it will use.
