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.

New European charging network will offer speeds up to 350 kW

It's about to get easier to fast-charge your electric vehicle across Europe thanks to four major automakers working together in a new joint venture. BMW, Daimler (Mercedes-Benz), Ford, and the VW Group (Audi and Porsche) have all signed a Memorandum of Understanding to install about 400 DC fast charging sites in Europe. As you may know, there are different types of fast chargers, but the ones that this group is talking about installing will be able to charge an EV in much less time than other stations. That's because these chargers will offer power levels of "up to 350 kW." Compare that to what's generally considered the current gold standard, the Tesla Superchargers, which have rates of up to 145 kW and a statement not that long ago from a Ford exec that suggested that 150 kW chargers would be the new normal. Of course, the Tesla chargers use the company's proprietary connector and the new network the JV is setting up will use the CCS standard. The first new stations will go up in 2017 and those 400 sites are just the beginning. A joint statement by the JV says that EV drivers will "have access to thousands of high-powered charging points" by 2020 along highways and main roads. "The charging experience is expected to evolve to be as convenient as refueling at conventional gas stations," the companies said. While not every electric vehicle will be able to take advantage of the 350 kW charging rate, the companies involved would be silly to build the infrastructure without vehicles that can handle that kind of energy flow. The JV says it would welcome participation from other automakers and will cooperate with interested regional partners.

Audi RS3 Sedan coming to America with over 400 hp?

The Mercedes-Benz CLA45 AMG is a fast, competent car. It's significantly sharper than the Audi S3, and it should be, since its starting price is around $7,000 more. Still, getting walloped by the higher-performing CLA45 AMG must irk some people at Audi, we'd think, which might explain why there are rumors that the S3's big brother is coming to town. Yes, reports are popping up from an Audi of America employee that the Audi RS3 would transition from its Euro-market Sportback body style to a more conventional four-door, and that its styling would be updated in the process. Oh, and it'll have a 400-plus-horsepower, 2.5-liter, five-cylinder turbo with which to bash the four-cylinder AMG. The report comes from Quattro World by way of CarScoops, and goes on to claim that Audi hallmarks like Quattro all-wheel drive and a seven-speed S-Tronic dual-clutch transmission will both be present. The new RS3 Sedan would arrive on US shores in 2017 as a 2018 model, with prices starting between $55,000 and $60,000. That should make Mercedes-AMG very nervous – the CLA45 may start around $50,000, but getting it past the $60,000-range is simple (your author was driving a nearly $68,000 CLA45 just last month, for example). Naturally, we have a call in with Audi of America to see if there's any credence to this report. Stay tuned for updates. Related Video:
