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-AMG to phase out 5.5-liter V8 after next year [UPDATE]

UPDATE: A previous version of this story indicated that AMG's 6.0-liter twin-turbo V12 was still mated to a five-speed automatic transmission, however the latest models (including the S65 AMG sedan and coupe, SL65 roadster and G65 sport-ute are equipped with the newer seven-speed unit. Mercedes also reached out to point out that the 5.5-liter engine will be phased out gradually, not overnight. There's a lot to love about AMG's 5.5-liter twin-turbo V8. It produces as much as 577 horsepower and 590 pound-feet of torque, and delivers blistering performance to even the heaviest of vehicles. But try not to get too attached, because like its 6.2-liter, naturally aspirated predecessor, it's not long for this world. The latest word comes from Autocar, which reports that Mercedes will release the last applications for the 5.5 biturbo within these next two calendar years in the new GLE63 AMG and upcoming S63 AMG convertible. After that, even though it was only introduced in 2011, it will be phased out. Fortunately Affalterbach has a worthwhile successor already in place in the 4.0-liter twin-turbo V8 from the Mercedes-AMG GT. The smaller powerplant, already in store for the new C63, is already producing 503 hp and 479 lb-ft in S spec. That's still shy of the larger unit's output, but where the 5.5 is nearing the end of its production cycle, the 4.0 is just starting out. Of course the 4.0-liter biturbo isn't the only engine AMG is making these days. Smaller models (based on the front-drive platform) employ the 45-designation, high-output 2.0-liter turbo four. Models at the very top of the lineup, however, use a 6.0-liter twin-turbo V12 that may be a dinosaur, but with 621 hp and 738 lb-ft of torque on tap, still can't be beat.

Mercedes details plans for move to Georgia

Automakers are getting restless in America, moving their headquarters from one location to another. Toyota is shifting its US operations to Dallas, Porsche is moving to a new headquarters across town, Cadillac is relocating from Detroit to New York, but lately the news has been about Mercedes. The German automaker has run its US operations out of its current facility in Montvale, NJ for decades, but now it's preparing to relocate to a new facility in Atlanta. And it has just announced further details of the move. The company is building a new facility at the corner of Abernathy and Barfield in Sandy Springs outside of Atlanta. That's right near where the Georgia 400 meets Interstate 285 near Hartsfield-Jackson airport, giving Mercedes access to an existing infrastructure of hotels, restaurants and of course transportation routes. The facility will take up a 12-acre plot of land and is earmarked for completion in early 2018. Lest you think MBUSA will stay put in Montvale in the meantime, though, it won't. The company is actually going to relocate twice, moving in the meantime to a temporary, 186,000-square-foot facility at the Perimeter Center in Dunwoody, GA. That move will kick off in July. The move detailed earlier this week at a press conference at the Georgia State Capitol with Governor Nathan Deal will see Mercedes hiring hundreds of new employees in Atlanta. Even after it moves down south, though, the company will keep certain functions in New Jersey, both in Montvale and in Robbinsville where it has its parts distribution center. MERCEDES-BENZ USA ANNOUNCES DETAILS OF NEW CORPORATE HEADQUARTERS IN ATLANTA MBUSA to occupy interim office space in Central Perimeter before opening new, state-of-the-art facility in 2018 February 03, 2015 - ATLANTA -- At a press conference today at the Georgia State Capitol, Mercedes-Benz USA (MBUSA) announced the permanent and interim locations for its new corporate headquarters in Atlanta. Company President and CEO Stephen Cannon made the announcement with Georgia Governor Nathan Deal. MBUSA, which is currently headquartered in Montvale, New Jersey, will construct a new, state-of-the-art headquarters facility on a greenfield site located at the corner of Abernathy and Barfield roads in Sandy Springs, expected to be completed in early 2018.
