Trump reportedly says he wants to wipe German cars off the U.S. map

BERLIN/FRANKFURT — A report that U.S. President Donald Trump has threatened to pursue German carmakers until there are no Mercedes-Benz rolling down New York's Fifth Avenue dented shares in the luxury car manufacturers on Thursday. An excerpt from German magazine Wirtschaftswoche's article, which cited several unnamed European and U.S. diplomats but did not include any direct quotes, could not be independently verified, while a U.S. Embassy spokesman in Berlin referred questions to Washington. The news and current affairs magazine said Trump had told French President Emmanuel Macron in April that he aimed to push German carmakers out of the United States altogether. Macron's administration in Paris declined to comment on the report. The Trump administration last week opened a so-called Section 232 trade investigation into vehicle imports, which could result in a 25 percent tariff on cars on the same "national security" grounds Washington used to impose metals duties in March. This could destroy exports by German carmakers, which control 90 percent of the U.S. premium market and are the biggest European Union exporters of cars to the United States. BMW owns Rolls-Royce, while Daimler has Mercedes-Benz, and Volkswagen controls Bentley, Bugatti, Porsche and Audi. Daimler, BMW and Audi declined comment. Porsche was not immediately available for comment. BMW shares were trading 0.5 percent lower at 0939 GMT, while Daimler and VW's shares were down 1 percent and 1.6 percent respectively, underperforming Germany's blue-chip DAX. Trump has railed against German carmakers before. And in early 2017, in an interview with German newspaper Bild, he said he would impose 35 percent tariffs on imported cars. At the time, the president called Germany a great car producer but said that the business relationship with the United States was an unfair one-way street. Germany's auto industry association VDA says its members exported 657,000 vehicles to North America last year, with total exports of vehicle components, cars, engines, as well as second-hand vehicles totaling 31.2 billion euros in 2016. Imports from the United States to Germany amounted to 7.4 billion euros, meaning a trade deficit of 23.8 billion euros the VDA's latest available figures show. However, German brands also have huge factories in the United States, where they built 804,000 cars last year, VDA said, providing jobs for U.S. workers. Berlin has reacted angrily to the U.S.

Mercedes spotted testing new S-Class cabrio in the snow

A fullsize luxury convertible is a rare species. There's the Bentley Continental GTC, maybe the Aston Martin DB9 or Vanquish Volante and the Maserati GranTurismo Convertible if you won't need those rear seats too often, but that's about it. The segment seems to be expanding, though, with the imminent arrival of the drop-head version of the Rolls-Royce Wraith and the new challenger you see here. Spied undergoing winter testing in Sweden, this prototype for the upcoming Mercedes-Benz S-Class Cabriolet is wearing barely any camouflage or body cladding whatsoever. In all likelihood that's largely because it's essentially the S-Class Coupe we already know, but with a folding fabric roof: Mercedes typically keeps the origami tin-tops to two-seaters like the SL and SLK. When the new S-Class cabrio is ready to launch – probably sometime between now and the summer – it'll join an expanding array of convertible Benzes that already includes the aforementioned SL and SLK and the E-Class Cabriolet, and will soon adopt the AMG GT roadster as well.

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.
